    STATE OF CONNECTICUT v. JOSHUA
    KOMISARJEVSKY
    (SC 18973)
    Robinson, C. J., and Palmer, D’Auria, Mullins,
    Ecker, Alvord and Keller, Js.*
    Syllabus
    Convicted of numerous crimes, including six counts of capital felony, in
    connection with the invasion of the P family home in the town of
    Cheshire that resulted in a triple murder, sexual assaults, kidnappings,
    and arson, the defendant appealed to this court. The defendant, along
    with his accomplice, S, entered the home around 2 a.m. and proceeded
    to tie up the members of the P family, which consisted of J, her husband,
    W, and their daughters, H and M. Discovering that there was no money
    in the house, and concerned that his and the defendant’s DNA would
    be found there, S drove J’s car to a nearby gas station to buy gasoline
    and then, around 9 a.m., took J to a bank so she could withdraw a large
    sum of cash. While S was gone, the defendant sexually assaulted M and
    took sexually explicit photographs of her with his cell phone. After
    returning to the home, S sexually assaulted J and strangled her to death.
    Upon realizing that W was escaping and that the police, responding to
    a 911 call from the bank, were surrounding the house, S poured gasoline
    throughout the home, ignited it, and fled with the defendant in J’s car.
    The defendant and S crashed the vehicle and were apprehended, while
    H and M perished in the ensuing fire. S was tried first and convicted.
    Prior to the defendant’s trial, the defendant filed a motion to change
    the venue from the judicial district of New Haven, arguing that the
    pretrial publicity surrounding his case, exacerbated by coverage of S’s
    trial, would prevent him from empaneling an impartial jury. The trial
    court denied the motion. The jury returned a guilty verdict, and the trial
    court rendered judgment in accordance with the verdict, from which
    the defendant appealed to this court. Held:
    1. The trial court did not violate the defendant’s right to a fair trial by an
    impartial jury in denying his motion to change the venue from the judicial
    district of New Haven or in denying his challenges for cause to twelve
    prospective jurors:
    a. There was no merit to the defendant’s claim that the pretrial publicity
    surrounding his case created an irrebuttable presumption of prejudice
    that would have required moving the trial from New Haven, because,
    although certain factors relevant to determining whether prejudice
    should be presumed favored the defendant, namely, the nature of the
    media coverage and whether the passage of time had alleviated the
    impact of the prejudicial publicity, the extensive jury selection process
    employed by the trial court in this case, along with the characteristics
    of New Haven’s population, strongly favored the state with respect to
    whether to presume prejudice: certain media coverage of the incident,
    particularly remarks from a state senator calling for the defendant to
    be hanged in the street by his genitalia and commentary from a bipartisan
    array of state politicians citing the home invasion in support of the death
    penalty, evoked the sort of community wide rush to judgment that can
    trigger a presumption of prejudice, and, because the defendant’s case
    was tried only several months after S was convicted and sentenced, the
    passage of time between the home invasion and the defendant’s trial
    did not mitigate the impact of that prejudicial publicity; nevertheless,
    when compared to other geographic regions that courts have considered
    sufficiently populous to permit the selection of an impartial jury, the
    size and diversity of New Haven, which had an urban and suburban
    population of 846,000 at the time of trial, greatly increased the feasibility
    of identifying an impartial jury, and the jury selection process in the
    present case, which allowed the attorneys for the state and the defendant
    to assess each prospective juror’s familiarity with the case and ability to
    render an impartial verdict, which afforded each party forty peremptory
    challenges instead of the minimum thirty required in capital cases, and
    which left open the possibility of a change in venue in the event that
    individual voir dire did not result in the empaneling of an impartial jury
    in New Haven, outweighed the inflammatory nature of the publicity
    associated with the case such that the defendant failed to surmount the
    extremely high bar necessary to establish the existence of presump-
    tive prejudice.
    b. The extensive pretrial publicity surrounding the defendant’s case did
    not result in actual prejudice that deprived the defendant of a fair trial, as
    the voir dire process by which the jury was selected was constitutionally
    adequate: the individual voir dire process did not consist of the blind
    acceptance of prospective jurors’ assurances of impartiality but involved
    a lengthy and thorough probing of their responses to questions by the
    state, the defendant, and the trial court, the defendant did not exhaust
    his peremptory challenges until the voir dire of the backup alternate
    jurors, after the regular and alternate jurors had been selected, or chal-
    lenge for cause any juror who actually deliberated in his case, and the
    trial court implemented thorough measures to ensure the jury’s continued
    impartiality through daily admonishments counseling the avoidance of
    any publicity; moreover, a detailed, juror by juror analysis of the jury
    selection record, which focused on the extent of each juror’s exposure
    to pretrial publicity and its effect on his or her case knowledge and
    impartiality, revealed that each juror who deliberated at trial and sentenc-
    ing repeatedly expressed his or her ability to be fair and impartial, to
    apply the appropriate burden of proof and the presumption of innocence,
    and not to be swayed by sympathy or to be affected emotionally after
    viewing disturbing evidence; furthermore, the fact that some of the jurors
    expressed sympathy for W and the P family did not indicate that they
    were so impartial that they could not set aside their impressions to
    return a verdict on the basis of the evidence, none of the jurors was
    personally affected by the events at issue, and the fact that several
    prospective jurors lost their composure and made inappropriate out-
    bursts, including crying openly in court and making menacing comments
    about or toward the defendant, did not deprive the defendant of a fair
    trial because the trial court questioned the prospective jurors who had
    witnessed the outbursts to ensure that the outbursts would not affect
    the jurors’ impartiality; accordingly, in light of the deference appellate
    courts afford to a trial court’s assessment of the impact of pretrial
    publicity on juror impartiality, this court concluded that the trial court
    had correctly determined that the pretrial publicity did not result in
    actual jury prejudice.
    c. The defendant could not prevail on his claim that the trial court
    had abused its discretion in denying his challenges for cause to twelve
    potential jurors because any error was harmless; an improper denial of
    a for cause challenge is not prejudicial unless the defendant shows that
    the ruling resulted in an identifiable, objectionable juror actually serving
    on the jury that decided the case, and none of the twelve jurors that the
    defendant challenged for cause actually deliberated on his case or
    decided his guilt.
    2. The trial court did not abuse its discretion in denying the defendant’s
    motions for a continuance, to reopen the evidence, and for a mistrial,
    which were all based on his contention that the state had improperly
    failed to disclose until after the close of evidence approximately 130
    pages of letters written by S while S was incarcerated, as there was no
    miscarriage of justice or prejudice resulting from the late disclosure of
    the letters: even if the letters, which, according to the defendant, con-
    tained S’s admissions that he was the mastermind behind the home
    invasion and that he previously had raped, tortured, and murdered seven-
    teen other women and girls, were admissible, nothing contained therein
    was exculpatory or directly supported the defendant’s theory that he
    did not intend for anyone to be killed, as the letters indicated that the
    home invasion was a joint venture and contradicted certain theories of
    defense proffered at trial, namely, that the defendant did not engage in
    anal intercourse with M and that it was S who had poured the gasoline
    throughout the house; moreover, the trial court properly found that the
    letters likely would have reinforced the basis for a guilty verdict and
    would have served to establish certain aggravating factors needed to
    secure a death sentence during the penalty phase.
    3. The defendant could not prevail on his claim that the state had violated
    his due process rights under Brady v. Maryland (
    373 U.S. 83
    ) by failing
    to disclose recordings of certain communications made by various
    Cheshire police officers during and after the response to the home
    invasion:
    a. The trial court correctly determined that it was the defendant’s burden
    to prove, by a preponderance of the evidence, the existence of a police
    communications log, which J’s sister, C, claimed to have received via
    e-mail several months after the home invasion and which purportedly
    established that police officers were present at the P home when S
    and J returned from the bank, the preponderance standard having been
    consistent with the one required by federal and sister state courts for a
    defendant to prove the existence of purported Brady evidence and with
    the standard used by Connecticut courts to make other preliminary
    determinations of fact involving a defendant’s constitutional rights; more-
    over, the trial court did not commit clear error in finding that the defen-
    dant had failed to prove the existence of the e-mail or the communications
    log it contained by a preponderance of the evidence because, even though
    the trial court found that the testimony of C was credible and that she
    had no motive to help the defendant by fabricating evidence, C had
    deleted the e-mail and lost her only printout of it, making it impossible
    to determine its provenance, C did not know who sent the e-mail, a
    search of the Cheshire Police Department’s records did not reveal a
    corresponding communication, despite C’s belief that someone from the
    department had sent it, and the log had not been turned over to the
    defense; furthermore, any error on the part of the trial court in sustaining
    the state’s objection, during an evidentiary hearing, to a question about
    whether the e-mail appeared to have been created by the police was
    harmless.
    b. Certain undisclosed communications regarding the Cheshire Police
    Department’s response to the bank’s 911 call, which the parties agreed
    constituted impeachment evidence insofar as it supported the defen-
    dant’s theory that the testifying officers’ embarrassment over the alleg-
    edly inadequate response colored their testimony, were not material,
    and, therefore, the state’s failure to disclose them did not violate Brady;
    none of the communications would have impeached the veracity of the
    officers who testified with respect to the principal issues disputed during
    the guilt phase of the trial, namely, whether the defendant committed
    an anal sexual assault of M and his intent to kill J, H, and M, as DNA
    evidence recovered from M’s body provided overwhelming support for
    the jury’s verdict with respect to the defendant’s sexual assault of M,
    any inadequacy in the police response bore no relation to the defendant’s
    theory that the DNA had been contaminated by a laboratory technician,
    and none of the circumstantial evidence on which the state relied to
    prove the defendant’s intent depended in any way on the observations
    or veracity of the officers who testified.
    c. Statements made by certain police officers describing the defendant
    as ‘‘simple as they come’’ and ‘‘nobody home,’’ and S as looking ‘‘evil,’’
    were not material for Brady purposes: the officer who described the
    defendant’s demeanor observed the defendant only fleetingly in a police
    station hallway and took no part in the response to the home invasion,
    the investigation, or any interviews with the defendant, and it was not
    reasonably likely that the officer’s testimony would have influenced the
    jury on the issue of the defendant’s demeanor in light of more probative
    evidence in the record, namely, a detective’s testimony that the defendant
    was emotionless following his arrest and the recording of the defendant’s
    statement to the police; moreover, the statement describing S as looking
    evil was a casual observation that, in the absence of anything further,
    did nothing to inform the jury’s assessment of what actually happened
    in the P residence or to support the defendant’s theory that S was the
    mastermind behind the home invasion and that the defendant wanted
    no part in killing J, H, or M.
    4. There was no merit to the defendant’s claim that the state had violated
    his due process right to a fair trial by presenting evidence that it knew
    or should have known to be false or misleading, namely, the testimony
    of an expert witness, B, that an inflammatory photograph of female
    genitalia found on the defendant’s cell phone depicted M, as that testi-
    mony was not material: even if B’s testimony was false or substantially
    misleading, there was no reasonable probability that it would have
    affected the jury’s verdict, it having been undisputed that the other five
    photographs in the exhibit containing the purportedly inflammatory
    photograph were in fact of M, which corroborated the defendant’s state-
    ment to the police that he had taken photographs of M for his personal
    use, and the content of the image did not bear on the principally con-
    tested issues in the guilt phase, that is, whether the defendant had
    sexual assaulted M anally and whether he had the requisite intent to
    kill; moreover, if the person depicted in the photograph was not M, it
    necessarily had to have been H, which would have introduced an addi-
    tional sexual assault victim to the case.
    5. The defendant’s challenge to the statute (§ 18-10b) imposing certain
    restrictive conditions of confinement on inmates, like the defendant,
    who have been convicted of capital felony or murder with special circum-
    stances was not reviewable on direct appeal: the record was insufficient
    to resolve the defendant’s claims that the conditions of confinement set
    forth in § 18-10b are unconstitutional on the grounds that they constitute
    an ex post facto law, violate equal protection, and are excessive and
    disproportionate, as there was no evidence beyond an averment of
    information and belief with respect to the claimed disparate treatment
    of defendants who had received life sentences after the abolition of the
    death penalty, as compared to capital defendants who previously had
    received life sentences, and there was no evidence as to the conditions of
    confinement actually imposed on the defendant, who was incarcerated
    in Pennsylvania; moreover, the proper vehicle by which the defendant
    may challenge his conditions of confinement is a petition for a writ of
    habeas corpus, and the defendant can present evidence that is relevant
    to his claim before the habeas court, which is empowered to make
    factual findings on the basis of that evidence.
    Argued October 17, 2019—officially released April 12, 2021**
    Procedural History
    Information charging the defendant with six counts
    of the crime of capital felony, four counts of the crime
    of kidnapping in the first degree, three counts of the
    crime of murder, and one count each of the crimes of
    sexual assault in the first degree, burglary in the second
    degree, arson in the first degree and assault in the sec-
    ond degree, brought to the Superior Court in the judicial
    district of New Haven, where the court, Blue, J., denied
    the defendant’s motions for a change of venue, to
    sequester the jury, to continue jury selection, to strike
    the jury panel, for additional peremptory challenges
    and to excuse tainted jury panels; thereafter, the case
    was tried to the jury before Blue, J.; subsequently, the
    court denied the defendant’s motions for a continuance,
    to open the evidence, and for a mistrial; verdict of guilty;
    thereafter, during the penalty phase of the proceedings,
    the jury found the existence of an aggravating factor
    or factors that outweighed any mitigating factors; sub-
    sequently, the court, Blue, J., rendered judgment in
    accordance with the jury verdict and the jury’s findings
    during the penalty phase, and imposed a sentence of
    death with respect to the six capital felony counts, and
    the defendant appealed to this court; thereafter, the
    court, Blue, J., granted in part the defendant’s motions
    for augmentation and rectification of the record; subse-
    quently, the court, Blue, J., granted the defendant’s
    motion to correct an illegal sentence. Affirmed.

    Opinion
    ROBINSON, C. J. The principal issue in this appeal
    is whether Connecticut’s individual voir dire process
    protected the right of the defendant, Joshua Komisar-
    jevsky, to a fair trial by assessing and mitigating the
    prejudicial effects of pretrial publicity about this partic-
    ularly notorious case involving a home invasion in
    Cheshire that resulted in multiple fatalities. The defen-
    dant appeals1 from the judgment of conviction, ren-
    dered after a jury trial, of, among other crimes, six
    counts of capital felony in violation of General Statutes
    (Rev. to 2007) § 53a-54b. On appeal, the defendant
    claims, inter alia, that the trial court improperly (1)
    denied his motions to change the venue of his trial from
    the judicial district of New Haven (New Haven), (2)
    denied his challenges for cause to twelve prospective
    jurors, and (3) denied his motions to reopen the evi-
    dence, for a mistrial, or for a continuance because of
    the state’s belated disclosure of certain letters written
    by the defendant’s accomplice, Steven Hayes. The
    defendant also contends that the trial court unconstitu-
    tionally applied the stringent conditions of confinement
    set forth in General Statutes § 18-10b2 to the defendant
    when he was resentenced after his death sentence was
    vacated. Finally, the defendant contends that the state
    deprived him of his due process right to a fair trial by
    (1) failing to disclose certain communications among
    various Cheshire police officers during and after the
    response to the home invasion, in violation of Brady
    v. Maryland, 
    373 U.S. 83
    , 
    83 S. Ct. 1194
    , 
    10 L. Ed. 2d 215
     (1963), and (2) failing to correct materially false
    expert testimony about a highly inflammatory photo-
    graph of female genitalia found on the defendant’s cell
    phone in violation of Giglio v. United States, 
    405 U.S. 150
    , 
    92 S. Ct. 763
    , 
    31 L. Ed. 2d 104
     (1972), and Napue
    v. Illinois, 
    360 U.S. 264
    , 
    79 S. Ct. 1173
    , 
    3 L. Ed. 2d 1217
     (1959). We disagree with all of these claims and,
    accordingly, affirm the judgment of the trial court.
    The record reveals the following facts, which the jury
    reasonably could have found, and procedural history. In
    2007, the P family, consisting of W, an endocrinologist,
    J, his wife, who was a nurse, and their two daughters,
    seventeen year old H, and eleven year old M, lived in
    a house at 300 Sorghum Mill Drive in Cheshire. In the
    early evening of July 22, 2007, the defendant went to
    the Stop and Shop supermarket at the Maplecroft Plaza
    in Cheshire to meet a contractor who owed him wages
    for construction work. While in the Stop and Shop park-
    ing lot, he saw J and M, who were there shopping for
    dinner. Intrigued by J’s car, a Chrysler Pacifica, the
    defendant followed J and M to the P residence, and
    was further impressed by their apparent prosperity.
    The defendant then contacted Hayes, with whom he
    had been communicating by text message about plans
    to make money in some way. After spending the evening
    caring for his daughter, the defendant returned to the
    Stop and Shop parking lot at approximately 10 p.m.,
    where he met Hayes. After driving around for a while
    in the defendant’s van discussing ways to make money,
    including robbing people who were using ATMs or com-
    ing out of bars, the defendant remembered J and M
    from earlier in the evening and told Hayes about them.
    After some discussion, Hayes and the defendant came
    to believe that there might be a lot of money in the P
    family home.
    After driving around for a while longer, the defendant
    and Hayes went to Sorghum Mill Drive in the defen-
    dant’s van, parked around the corner from the P family
    residence, and donned rubber gloves and face masks
    improvised from cut up shirts and a hat. Hayes brought
    with him a pellet gun that he had purchased the day
    before at a nearby Wal-Mart while accompanied by the
    defendant; the pellet gun looked like a nine millime-
    ter pistol.
    At approximately 2 a.m. on July 23, 2007, the defen-
    dant and Hayes approached the P residence and walked
    around the house. They noticed that W was sleeping
    on a couch in the sunroom. The defendant then entered
    the house through an unlocked bulkhead door to the
    basement. The defendant found a baseball bat in the
    basement and carried it with him to the sunroom, where
    he repeatedly struck W in the head with the bat, causing
    W to make an ‘‘unearthly scream.’’ After W, who was
    bleeding profusely and confused, backed into the cor-
    ner of the couch and quieted down, the defendant let
    Hayes into the house through the back door.
    After W stirred and sat up, Hayes pointed the pellet
    gun at him. The defendant then ordered W to lie down
    on the couch and covered his bleeding head with a
    towel; Hayes and the defendant bound W’s wrists and
    ankles with a cotton rope clothesline that the defendant
    had found on the basement stairs. The defendant told
    Hayes to ‘‘put a bullet in’’ W if he were to move, and
    said to W, ‘‘if we get the money, nobody will be hurt
    . . . .’’ In response to the defendant’s questions about
    whether anyone else was in the house, W told him that
    J, H, and M were upstairs. Hayes and the defendant
    then tied up J and M, who were sleeping in the same
    bed in the master bedroom, and went into H’s bedroom
    and tied her up, as well.
    After talking with J and searching the house, the
    defendant and Hayes concluded around 4 a.m. that there
    was no money there, but they realized from the check
    register and receipts in J’s purse that W and J had
    approximately $40,000 in their Bank of America
    accounts; they asked W and J about that money at
    various points during the encounter. The defendant and
    Hayes decided to wait until the bank opened at 9 a.m.,
    at which point Hayes would take J there to withdraw
    $15,000, an amount that they believed would not raise
    a ‘‘red flag . . . .’’ The defendant and Hayes then went
    back upstairs and retied the ropes binding J, H, and M,
    making sure to secure them to their bedframes. The
    defendant and Hayes took all of the family’s portable
    and cell phones that they could find and drove the
    Pacifica and the defendant’s van to a nearby condomin-
    ium complex on Mountain Road, where, to avoid trig-
    gering any of the neighbors’ suspicions, they parked
    the defendant’s van before returning to the house in
    the Pacifica.
    At approximately 5 a.m., the defendant and Hayes
    moved W from the sunroom down to the basement in
    order to avoid the possibility that a neighbor might see
    him through the sunroom window. They tied W to a
    support pole in the basement with a rope, sat him on
    a pillow, and rebound his feet with a plastic zip tie.
    Shortly thereafter, J, acting at Hayes’ direction, called
    W’s medical office and asked a nurse to cancel his
    morning schedule because he was ill.
    During the encounter, the defendant spoke to M sev-
    eral times about her summer plans and schooling; he
    also brought her water and provided her with bathroom
    breaks. In the meantime, tensions continued to rise
    between Hayes and the defendant because Hayes
    expressed concern to the defendant about having left
    traces of their DNA in the house; Hayes then proposed
    burning down the house and kidnapping the victims
    using the family’s vehicles. A short time later, Hayes
    became angrier because he believed that the defendant
    had used his real name in front of the victims, and he
    proposed killing them instead. Hayes found several one
    gallon bottles of windshield washer fluid in the garage
    and emptied them into the kitchen sink. At approxi-
    mately 8 a.m., Hayes drove the Pacifica to a nearby
    Citgo service station and filled four of the containers
    with gasoline, communicating with the defendant sev-
    eral times on his cell phone while he was out. Hayes
    then returned to the house and left those four containers
    in the garage.
    Shortly before 9 a.m., Hayes and J drove in the Pacif-
    ica to the Bank of America branch located at the
    Maplecroft Plaza near the Stop and Shop. To emphasize
    the gravity of the situation to J, Hayes called the defen-
    dant on his cell phone while they were driving to the
    bank and asked about W, H, and M. When they arrived,
    J entered the bank by herself and told Kristin Makh-
    zangi, a teller, that she needed to withdraw $15,000
    because two men were holding her family hostage in
    their house. Because there was not enough money in
    the account that J desired to use, and J lacked the
    identification required to make withdrawals from her
    other accounts, Makhzangi relayed this information to
    Mary Lyons, the branch manager. Lyons then came out
    to speak with J, who told her that the two men had
    been polite and had promised to free the P family upon
    receiving the money. Lyons subsequently approved the
    withdrawal of $15,000 from a home equity line of credit
    and notified the Cheshire police at approximately 9:21
    a.m. of the ongoing hostage situation at the P family
    house; she provided the police with descriptions of J
    and Hayes, whom she had seen waiting in the Pacifica.
    In the meantime, Makhzangi gave J $15,000 in cash,
    packaged in three straps of $50 bills, from the vault. At
    9:23 a.m., J exited the bank, where Hayes picked her
    up in the Pacifica, and drove back to the P family house.
    While Hayes was out of the house purchasing gas
    and going to the bank with J, the defendant went to
    check on W and H, who were still tied up in the base-
    ment and on her bed, respectively. The defendant then
    went to M’s bedroom and, after some additional conver-
    sation, cut her clothes off and sexually assaulted her
    anally.3 The defendant also took several sexually
    explicit photographs of M using the camera on his cell
    phone. After committing the sexual assault, the defen-
    dant allowed M to shower and poured bleach on her
    shorts in an attempt to eliminate traces of his DNA.
    When Hayes and J returned from the bank with the
    money, he and the defendant retied J’s hands and feet
    and put her on the couch in the living room. Hayes and
    the defendant then moved into the dining room and
    argued again about whether it was necessary to kill the
    family to avoid detection. Hayes initially planned to
    strangle the family using nylon stockings, and he paced
    around the house to ‘‘psyche himself up . . . .’’ Hayes
    then went into the living room where he was alone with
    J for approximately fifteen minutes, at which point he
    sexually assaulted her vaginally and strangled her to
    death.
    Meanwhile, W’s weight had caused the ropes binding
    him to loosen as he slumped over while drifting in and
    out of consciousness; when he awoke, he was able to
    free himself from the bindings. W heard numerous
    noises from his position in the basement, including loud
    thumps and the Pacifica leaving from the garage. Rather
    than confront the defendant and Hayes himself, W
    chose to escape the basement via the bulkhead door,
    and he crawled to the home of his next door neighbor,
    David Simcik, for help. When Simcik saw W, he told
    his wife to call 911 because of W’s visible injuries. While
    Simcik’s wife was on the phone with the police dis-
    patcher, two Cheshire police officers, Dennis Boucher
    and Thomas Wright, appeared, having been dispatched
    in response to the call from the bank,4 and asked
    whether there was anyone still in the house. W informed
    them that J, H, and M were still in the house. W was
    subsequently transported by ambulance to St. Mary’s
    Hospital in Waterbury, where he was admitted for sev-
    eral days and treated for head injuries, including the
    loss of five to seven pints of blood.
    In the meantime, the defendant, who had heard the
    basement bulkhead door opening, yelled to Hayes that
    W was escaping. Instead of chasing W, the defendant,
    who saw J’s lifeless body on the living room floor, told
    Hayes that they had to leave immediately. Hayes took
    a bag that had the money from the bank, gave it to
    the defendant, and told him to start the car. While the
    defendant looked for the car keys, he saw Hayes pour-
    ing copious quantities of gasoline from the windshield
    washer fluid containers around the house, including in
    the living room, stairways, hallway, and master bed-
    room. At this time, H and M were still restrained in
    their bedrooms. Realizing that the police were starting
    to arrive and surround the house, the defendant started
    the Pacifica in the garage as Hayes flicked a lit match
    into the kitchen, igniting a pool of gasoline on the floor
    and causing flames to travel toward the front hallway
    of the house. The first responding police officers were
    unable to gain access to the interior portions of the
    house because of heat and flames from the rapidly
    spreading fire, in which H and M perished.5
    After Hayes jumped into the passenger seat of the
    Pacifica, the defendant backed down the driveway at
    a high rate of speed, first striking the front passenger
    side of an unmarked police car driven by Captain Robert
    Vignola, a Cheshire police detective, which had pulled
    up to block the driveway, and then a small stone wall
    at the front of the lawn. Vignola and Boucher, along
    with another officer, Sergeant Philip Giampietro, drew
    their weapons and approached the passenger side of the
    Pacifica while commanding the defendant and Hayes
    to exit the vehicle with their hands up. The defendant,
    however, was able to recover control of the Pacifica
    and drove it at a high rate of speed down Sorghum
    Mill Drive, first at Sergeant Christopher Cote, who was
    standing in the road with a long rifle but was able to
    jump out of the way, and then toward a bend in the
    road where he crashed into a pair of police cruisers
    that had parked in a V formation to block the road,
    causing the airbags to deploy and the vehicle to stop.
    At that point, multiple police officers apprehended the
    defendant and Hayes. When questioned after being
    grabbed forcefully by Joseph Vitello, a Cheshire police
    detective, the defendant told the officers that there were
    no other accomplices, that he believed J was dead, and
    that there were ‘‘two girls in the upstairs . . . front
    facing bedrooms, and that they were still alive.’’6 The
    officers placed the defendant and Hayes under arrest.
    After his arrest, the defendant waived his rights and
    gave a detailed statement to the investigating officers,
    including Vitello and Rafael Medina, a state police
    detective, which was admitted into evidence at trial.7
    The state charged the defendant with six counts of
    capital felony in violation of General Statutes (Rev. to
    2007) § 53a-54b, three counts of murder in violation of
    General Statutes § 53a-54a (a), four counts of kidnap-
    ping in the first degree in violation of General Statutes
    § 53a-92 (a) (2) (B), one count of sexual assault in the
    first degree in violation of General Statutes § 53a-70
    (a) (1), one count of burglary in the second degree in
    violation of General Statutes § 53a-102, one count of
    arson in the first degree in violation of General Statutes
    § 53a-111 (a) (1), and one count of assault in the second
    degree in violation of General Statutes § 53a-60 (a) (2).
    The defendant and Hayes were tried separately in
    New Haven. Hayes was tried first in the fall of 2010;
    he was found guilty by a jury of, inter alia, multiple
    counts of capital felony and sentenced to death. In mid-
    2011, following extensive pretrial motions practice, the
    defendant’s case was tried to a jury, which returned a
    verdict of guilty on all counts. After a penalty phase
    trial with respect to the capital felony counts, the trial
    court sentenced the defendant in accordance with the
    jury’s verdict to six consecutive death sentences, fol-
    lowed by a term of imprisonment of 140 years. This
    direct appeal followed. See footnote 1 of this opinion.
    While this appeal was pending, this court held in
    State v. Santiago, 
    318 Conn. 1
    , 9–10, 
    122 A.3d 1
     (2015),
    and reaffirmed in State v. Peeler, 
    321 Conn. 375
    , 377,
    
    140 A.3d 811
     (2016), that the imposition of the death
    penalty on offenders convicted of capital felonies prior
    to the prospective abolition of the death penalty by
    statute on April 25, 2012, would violate the Connecticut
    constitution’s prohibition of cruel and unusual punish-
    ment. Accordingly, the trial court granted the defen-
    dant’s motion to correct an illegal sentence and vacated
    his death sentences; the trial court resentenced him to
    a total effective sentence of six consecutive sentences
    of life imprisonment without the possibility of release,
    followed by a term of imprisonment of 140 years.8
    On appeal, the defendant claims that (1) the trial
    court improperly denied his motion to change the venue
    of his trial from New Haven given the effects of prejudi-
    cial pretrial publicity, (2) the trial court improperly
    denied his challenges for cause to twelve prospective
    jurors, (3) the trial court improperly denied his motions
    for relief following the state’s disclosure of certain let-
    ters written by Hayes while he was incarcerated, (4)
    the prosecutor deprived him of his due process right to
    a fair trial by failing to disclose certain communications
    among various Cheshire police officers in violation of
    Brady, (5) the prosecutor failed to correct materially
    false expert testimony in violation of Napue and Giglio,
    and (6) the trial court unconstitutionally applied the
    stringent conditions of confinement pursuant to § 18-
    10b to the defendant after his death sentences were
    vacated. Additional facts and procedural history will
    be set forth in the context of each claim on appeal.
    I
    PRETRIAL PUBLICITY AND JURY
    SELECTION CLAIMS
    We begin with the defendant’s claims arising from
    adverse pretrial publicity about this case, which he con-
    tends sent the New Haven area into ‘‘paroxysms of
    inquisitional paranoia and communal hysteria.’’ Specifi-
    cally, the defendant argues, inter alia, that the trial court
    improperly denied (1) his motions for a change of venue
    and for a new trial, and (2) his challenges for cause to
    numerous jurors.9
    A
    Additional Relevant Facts and Procedural History
    On February 4, 2011, the defendant filed a motion to
    change the venue of the trial from New Haven to the
    judicial district of Stamford-Norwalk (Stamford). In
    that motion, the defendant argued that Stamford was
    ‘‘the most potentially neutral site’’ given the ‘‘unprece-
    dented, prejudicial publicity surrounding this case, as
    exacerbated by the recent trial of . . . Hayes,’’ during
    which Hayes attempted ‘‘to deflect responsibility for
    his crimes . . . .’’ In support of the motion, the defen-
    dant also filed an accompanying memorandum of law
    and a study that was undertaken by two psychology
    professors at the John Jay College of Criminal Justice
    of the City University of New York, Steven Penrod10
    and Margaret Bull Kovera,11 who conducted a telephone
    survey to analyze the effect of pretrial publicity in this
    case on potential jurors in several judicial districts,
    namely, New Haven, Fairfield, Stamford, and Danbury.12
    The study was intended to determine the proportion of
    qualified jurors13 who had heard about this case, the
    extent and sources of their knowledge about the case,
    and the degree to which they believed the defendant
    was guilty and had arrived at some judgment ‘‘about
    what the appropriate penalty would be for this case.’’
    The study concluded that New Haven was ‘‘resound-
    ingly the least favorable judicial district in terms of
    juror taint, whereas [Stamford was] the most favorable
    relative to affording [the defendant] the best opportu-
    nity to empanel a fair and impartial jury.’’14
    At a hearing on the motion to change venue, Penrod
    explained the study.15 He described the pretrial publicity
    as ‘‘[o]verwhelmingly negative’’ with respect to the defen-
    dant, with guilt and death penalty judgments running
    approximately 20 percent higher than they had in a
    similar study he had performed slightly more than one
    year before in connection with Hayes’ trial. Approximately
    97 percent of qualified jurors in Stamford recognized
    the case, and approximately 98 percent of qualified jurors
    in New Haven recognized it, either immediately by name
    or after being prompted with one cue, namely, that it
    was a home invasion. The lowest recognition level was
    in Danbury, with approximately 94 percent recognition.
    The recognition of this case in all four districts studied
    was comparable to the state court prosecution of Terry
    Nichols, who had bombed the Alfred P. Murrah Federal
    Building in Oklahoma City, after his conviction in fed-
    eral court, the Menendez brothers,16 and John Walker
    Lindh, the ‘‘American Taliban,’’17 in their respective
    jurisdictions. Penrod opined that the ‘‘least prejudicial’’
    of the four studied judicial districts would be Stamford
    because it is ‘‘generally the lowest across the board’’
    with respect to judgments about the defendant’s guilt
    and knowledge about the case. Penrod stated, however,
    that this was a matter of ‘‘relative disadvantage,’’ given
    that this case reflected ‘‘the highest levels of prejudg-
    ment of guilt’’ he had ever seen.
    Turning to a district by district analysis of the respon-
    dents’ knowledge about the case,18 Penrod noted that,
    although there was a very similar reported rate of fol-
    lowing the news media generally, approximately 70 per-
    cent of New Haven respondents followed this case ‘‘very
    closely’’ or ‘‘somewhat closely,’’ as compared to approx-
    imately 49 percent in Stamford.19 He determined that
    Stamford respondents had a much lower rate of case
    knowledge than those in New Haven, with 2.5 percent
    knowing the names of the defendant and Hayes sponta-
    neously and 58 percent after receiving a cue, as com-
    pared to 22 percent and 89 percent in New Haven,
    respectively. In Stamford, 73 percent were aware of
    Hayes’ conviction, in comparison to 88 percent in New
    Haven; with respect to Hayes’ death sentence, the
    awareness rates were 39 and 66 percent, respectively.
    Forty-nine percent of the New Haven respondents had
    seen or heard about W’s interview with Oprah Winfrey
    approximately one month before the survey took place,
    as compared to 31 percent in Stamford. Thirty-one per-
    cent of the respondents in New Haven had heard about
    the defendant’s prison journals, in comparison to 11
    percent in Stamford. Interestingly, more respondents
    in Stamford believed that the crimes were ‘‘disturbing/
    graphic’’ than those in New Haven, 5.6 and 4.9 percent,
    respectively, which is a difference that Penrod did not
    believe was statistically significant.
    Moving beyond general awareness to impartiality, in
    Stamford, 65 percent of the respondents had ‘‘very nega-
    tive’’ impressions of the defendant, as compared to 76
    percent in New Haven; there were 6 and 5 percent
    reports of ‘‘somewhat negative’’ impressions, respec-
    tively, for each jurisdiction.20 In Stamford, 50 percent
    of the respondents believed that the defendant was
    ‘‘definitely guilty’’ of murder, and 22 percent ‘‘probably
    guilty,’’ as compared to 60 and 25 percent, respectively,
    in New Haven.21 In New Haven, 71 percent of those
    surveyed reported that they could decide the case based
    solely on the evidence, as compared to 80 percent in
    Stamford. Thirty-two percent said that they could ‘‘defi-
    nitely’’ be ‘‘fair and impartial’’ in New Haven with
    respect to the defendant, and 18 percent ‘‘probably’’
    so, as compared to 44 and 22 percent in Stamford,
    respectively. Penrod stated that the ‘‘most significant’’
    difference between New Haven and Stamford was the
    number of respondents who believed that they could
    render a not guilty verdict, which was 15 percent in
    New Haven and 30 percent in Stamford. In Penrod’s
    view, this suggested that there were ‘‘twice as many
    people’’ prepared not to convict in Stamford, with Stam-
    ford below New Haven with respect to virtually every
    measure of knowledge about the case.22 Ultimately, Pen-
    rod described Stamford as ‘‘a venue that is . . . less
    prejudice[d] against the defendant [and that] has a
    smaller fund of knowledge [on] which that prejudice
    is based.’’
    During cross-examination, Penrod acknowledged
    that the publicity concerning this case was ‘‘extensive’’
    across all four of the surveyed districts, with the lowest
    level of recognition being approximately 94 percent in
    Danbury and the highest being approximately 98 per-
    cent in New Haven. Penrod also acknowledged that,
    with respect to some specific factors, there was greater
    recognition in Stamford than in New Haven, and that
    approximately 70 percent of the respondents in New
    Haven reported that they could render a verdict based
    just on the evidence, with approximately 50 percent of
    the respondents in New Haven ‘‘definitely’’ or ‘‘proba-
    bly’’ able to give the defendant a fair trial, despite that
    being a ‘‘somewhat lower’’ percentage answer than in
    Stamford.23
    Significantly, Penrod also acknowledged that studies
    indicated that more extensive voir dire processes were
    beneficial for the purpose of exploring a potential
    juror’s knowledge and attitudes about the case, and
    that there has not been research exploring the effect
    of voir dire lasting more than one hour in counteracting
    the effects of pretrial publicity. He agreed that Connecti-
    cut’s individual voir dire process is good—and ‘‘more
    than minimal’’ for counteracting adverse pretrial public-
    ity—and would be ‘‘[u]nquestionably’’ more effective
    than the phone survey. Penrod also conceded that it
    was not ‘‘impossible’’ to select a fair and impartial jury
    from New Haven but simply that it would be ‘‘more
    likely’’ to occur in Stamford, which would also present
    ‘‘significant difficulties’’ in that respect. Penrod agreed
    with the trial court’s observation that the difficulties of
    teasing out prejudices during voir dire would be present
    in either location.
    After the hearing, the trial court denied the defen-
    dant’s motion for a change of venue. In its memorandum
    of decision, the trial court emphasized that the cases
    had been widely reported on throughout the state—
    and, indeed, the world—observing that many of the
    media materials provided had been published on the
    Internet, as well as in print. The trial court noted that
    ‘‘at least 97 percent of Connecticut residents have at
    least heard’’ of the defendant and Hayes. Relying on
    Skilling v. United States,

    , 
    124 S. Ct. 1614
    , 
    158 L. Ed. 2d 254
    (2004), the trial court declined to presume the existence
    of prejudicial publicity prior to voir dire, emphasizing
    (1) that the large, diverse pool of jurors in New Haven,
    with a population of more than 846,000 people, rendered
    it distinct from the contaminated pool in the much
    smaller rural community at issue in Rideau, (2) that
    the survey respondents’ perceptions of guilt did not
    arise from admissions of guilt, (3) the lapse of four
    years from the crime to the time of trial, and (4) the
    fact that the jury in Hayes’ case, which had received
    similar publicity, had returned a verdict finding him not
    guilty of one count of arson, which suggested that jury
    impartiality was possible despite the extensive public-
    ity. The trial court contrasted Connecticut’s ‘‘particu-
    larly searching’’ individual voir dire process with the
    ‘‘vastly more truncated federal jury selection process
    found constitutionally adequate in Skilling’’ and empha-
    sized that ‘‘the parties will have ample opportunity to
    inquire about the effects of pretrial publicity on the
    individuals involved.’’ The court further stated that it
    would revisit its decision should voir dire not produce
    the requisite number of impartial jurors.
    Jury selection began on March 16, 2011, and ended
    on June 14, 2011.24 The court agreed with the parties’
    recommendation to seat twenty-one jurors, twelve regu-
    lar, six alternate, and three backup alternates. The trial
    court allotted each party forty peremptory challenges,
    ten more than the thirty mandated in death penalty
    cases under General Statutes 54-82h (a).25 The twelfth
    regular juror was selected on May 10, 2011; at that point,
    the state had used twenty-one peremptory challenges
    and the defendant twenty-eight. On June 8, 2011, after
    the six alternates had been chosen, the defendant had
    one peremptory challenge remaining. He requested
    forty more for the selection of the three backup alter-
    nates.26 The trial court denied that motion. Once jury
    selection was concluded on June 14, 2011, with the
    three backup alternates selected, each party had
    exhausted its challenges. None of the alternates was
    ultimately required to deliberate, and the defendant did
    not challenge for cause any juror who actually decided
    his guilt.
    On May 16, 2011, the defendant also filed a motion
    to continue the then pending jury selection in this case
    for approximately three months, arguing that Senator
    Edith Prague, a prominent state legislator and longtime
    opponent of the death penalty, had publicly announced
    her decision to withdraw her support for abolition of
    the death penalty after meeting with W. In announcing
    her decision, Senator Prague made comments, later
    reported in the Hartford Courant, the New Haven Regis-
    ter, and other print and broadcast media, that ‘‘ ‘[t]hey
    should bypass the [defendant’s] trial and take that sec-
    ond animal and hang him by his penis from a tree out
    in the middle of Main Street.’ ’’ Senator Prague reiter-
    ated her comments in television news interviews over
    the following days; she expressed no regret for having
    made them and emphasized her support for the P family,
    calling the defendant a ‘‘ ‘monster . . . .’ ’’ The defen-
    dant argued that this call for a ‘‘lynching’’ lent ‘‘legiti-
    macy’’ to similar views expressed in reader comments
    in online news stories about this case and further
    infected the venire. The defendant argued that a three
    month continuance would reduce the prejudicial effect
    of Prague’s call for a lynching by allowing it to ‘‘slip from
    the mind of potential jurors.’’ The trial court denied
    that motion.
    Over the monthslong jury selection process, the con-
    duct of several prospective jurors—none who ulti-
    mately served as jurors—evidenced the emotional
    impact of this case. Questioning during voir dire
    revealed that some prospective jurors had discussed
    with each other their distaste for the defendant, includ-
    ing a belief that he should immediately receive the death
    penalty. Other prospective jurors became emotional,
    with some refusing to enter the courtroom and others
    berating the defendant and openly stating their beliefs,
    either in open court or to court staff, that the defendant
    should ‘‘fry,’’ or offering to execute him personally.
    For example, one prospective juror, J.M.-M., after being
    peremptorily challenged by the defendant, screamed at
    him and called him a ‘‘[k]iller, asshole.’’ Another, B.G.,
    after being excused for hardship, offered to ‘‘take care
    of him right here.’’ Similarly, two alternate jurors, D.V.
    and J.B., who had been selected based on their assur-
    ances that they could withstand pressure and decide
    the case impartially, were stricken from the panel after
    they returned to court to express concern about their
    impartiality after friends and coworkers had questioned
    them about the case and offered unsolicited opinions.
    On September 12, 2011, the defendant renewed his
    motion for sequestration of the jury pursuant to Practice
    Book § 42-22, arguing that sequestration was necessary
    to preserve his right to an impartial jury in light of the
    pretrial publicity and the notorious nature of the case.
    The trial court denied this motion.
    On September 15, 2011, the defendant again moved
    for a change of venue from New Haven to Stamford,
    and to strike the selected jury panel, arguing that the
    subjective assessment of juror impartiality via the voir
    dire process was insufficient to protect his rights to a
    fair trial, as was demonstrated by the previously
    described statements of prospective jurors J.M.-M. and
    B.G. and alternate jurors D.V. and J.B. The defendant
    argued that the conduct of these individuals, along with
    the comments of others during voir dire, was indicative
    of the adverse effects of the pretrial publicity. The trial
    court denied this motion. After he was found guilty, the
    defendant renewed these pretrial publicity claims in his
    motion for a new trial, which the trial court also denied.
    B
    Review of the Defendant’s Pretrial Publicity
    Claims and General Governing Principles
    On appeal, the defendant relies on, among other
    cases, the United States Supreme Court’s decisions in
    Skilling v. United States, supra, 
    561 U.S. 358
    , and
    Rideau v. Louisiana, 
    supra,
     
    373 U.S. 723
    , and contends
    that, given the extensive, frenzied, and inaccurate media
    publicity in this ‘‘extreme’’ case, an irrebuttable pre-
    sumption of prejudice mandated moving the trial from
    New Haven to Stamford, which was the Connecticut
    venue mostly likely to yield an impartial jury. Arguing
    that Skilling is distinguishable because it was a white
    collar case that took place in the much larger city of
    Houston, Texas, the defendant argues that emotional
    outbursts in open court by multiple prospective jurors,
    with some openly weeping or shouting at him, demon-
    strated the impact on the New Haven juror pool of the
    media coverage of this crime, including Hayes’ earlier
    trial. The defendant contends that any presumption of
    prejudice cannot be rebutted because the voir dire in
    this case demonstrated that six of the eighteen seated
    jurors had preconceived notions that the defendant was
    guilty, ‘‘virtually all had substantial knowledge of the
    case,’’ and many had been told by family, friends, and
    other people that the defendant was guilty and should
    be sentenced to death. Overall, the defendant argues
    that ‘‘the voir dire proceedings establish beyond dispute
    that the jury selection process did not produce a jury
    untainted by pretrial publicity and community animus,’’
    with the seated jurors’ self-assessments that ‘‘they could
    be fair . . . [being] far from conclusive proof of their
    impartiality.’’27 (Internal quotation marks omitted.)
    In response, the state, citing, as an example, the Bos-
    ton Marathon bombing case; see In re Tsarnaev, 
    780 F.3d 14
     (1st Cir. 2015) (order denying petition for man-
    damus); contends that the trial court properly applied
    the factors articulated by the Supreme Court in Skilling
    v. United States, supra, 
    561 U.S. 382
    –83, in denying the
    motion for a change of venue, given the relatively large
    and diverse jury pool in New Haven, the ‘‘porosity of
    geographic boundaries due to the effects of the Internet’’
    on the media coverage of this case, Penrod’s study
    indicating that prospective jurors had greater aware-
    ness of the crime in general, rather than of the defendant
    personally, the fact that coverage of Hayes’ preceding
    trial and conviction would not disadvantage the defen-
    dant’s apparent strategy of asserting that Hayes was the
    ringleader, and the fact that Hayes’ jury had rendered
    a partial acquittal at his trial. The state also relies heavily
    on the ‘‘unique’’ protections provided by Connecticut’s
    constitutionally mandated individual voir dire process;
    Rozbicki v. Huybrechts, 
    218 Conn. 386
    , 392 n.2, 
    589 A.2d 363
     (1991); see Conn. Const., amend. IV; to demonstrate
    that any prejudice was rebuttable due to a lack of actual
    prejudice because the jury, as empaneled after a
    monthslong voir dire, was one that the defendant him-
    self had ‘‘accepted’’ as ‘‘actually . . . impartial,’’ and
    the trial court took precautions to protect that impar-
    tiality. The state posits that the jurors selected, although
    aware of the crimes generally, knew nothing about the
    primary contested issue in this case, namely, the role
    and relative culpability of each accused. We agree with
    the state and conclude that the trial court did not violate
    the defendant’s right to a fair trial by an impartial jury
    when it denied his motions for a change of venue from
    New Haven to Stamford because there was neither pre-
    sumptive nor actual prejudice resulting from the pre-
    trial publicity.
    We begin with the standard of review and background
    legal principles. ‘‘In requesting a change of venue, a
    defendant bears the burden of showing that he could
    not otherwise receive a fair and impartial trial. The trial
    court exercises its discretion in deciding whether to
    grant such a change of venue. . . . The trial court’s
    discretion is governed by Practice Book [§ 41-23], which
    provides: Upon motion of the prosecuting authority or
    the defendant, or upon his own motion, the judicial
    authority may order that any pending criminal matter
    be transferred to any other court location: (1) If the
    judicial authority is satisfied that a fair and impartial
    trial cannot be had where the case is pending . . . .
    Despite the broad discretion vested in the trial court in
    considering such a motion, its denial has constitutional
    implications and appellate review requires an indepen-
    dent evaluation of the circumstances upon which the
    claim of an unfair trial is based. . . .
    ‘‘For an appellate court to reverse a conviction on the
    [ground] of prejudicial pretrial publicity, a defendant
    generally must prove actual juror prejudice. . . . A
    defendant need not, however, show actual prejudice in
    extreme circumstances whe[n] there has been inher-
    ently prejudicial publicity such as to make the possibil-
    ity of prejudice highly likely or almost unavoidable.
    . . . A defendant cannot rely, however, on the mere
    fact of extensive pretrial news coverage to establish
    the existence of inherently prejudicial publicity. Promi-
    nence does not, in itself, prove prejudice. . . . Rather,
    [t]he defendant must demonstrate that the publicity
    was so inflammatory or inaccurate that it created a
    trial atmosphere utterly corrupted by press coverage.’’

    Indeed, ‘‘[t]o place our analysis of the defendant’s claim
    regarding the extensive publicity in context, we must
    recognize the first amendment right of a free press to
    observe and publicize criminal trials. . . . It follows
    naturally that the public will hear and read reports of
    such proceedings. Dissemination of such information
    and the accompanying publicity itself, therefore, [are]
    not constitutionally objectionable. Extensive publicity
    implicates the defendant’s due process rights only if it
    rises to a level sufficient to preclude a fair trial for the
    accused.’’ (Citation omitted; footnote omitted.) State v.

    Before we turn to the record in this case, we find
    instructive a detailed review of Skilling v. United
    States, supra, 
    561 U.S. 358
    , which is the United States
    Supreme Court’s most recent decision concerning pre-
    trial publicity. In Skilling, the court considered whether
    Jeffrey K. Skilling, the chief executive officer of Enron
    Corporation (Enron), had received a fair trial on crimi-
    nal charges arising from the collapse of that business
    in the federal district that included Houston, which had
    been its home. 
    Id.,
     367–68. Given the extensive and
    negative pretrial publicity about the case because of
    the severe economic consequences Enron’s collapse
    had on the Houston area; 
    id.,
     368–70; Skilling argued
    ‘‘that his trial ‘never should have proceeded in Houston.’
    . . . And even if it had been possible to select impartial
    jurors in Houston, ‘[t]he truncated voir dire . . . did
    almost nothing to weed out prejudices,’ . . . so ‘[f]ar
    from rebutting the presumption of prejudice, the record
    below affirmatively confirmed it.’ ’’ (Citation omitted.)
    
    Id., 377
    . The Supreme Court observed that ‘‘Skilling’s
    [fair trial] claim thus raise[d] two distinct questions.
    First, did the District Court err by failing to move the
    trial to a different venue based on a presumption of
    prejudice? Second, did actual prejudice contaminate
    Skilling’s jury?’’ 
    Id.
    The court began its analysis in Skilling with the
    ‘‘foundation precedent’’ of Rideau v. Louisiana, 
    supra,
    373 U.S. 723
    , in which ‘‘Wilbert Rideau robbed a bank
    in a small Louisiana town, [kidnapped] three bank
    employees, and killed one of them. Police interrogated
    Rideau in jail without counsel present and obtained his
    confession. Without informing Rideau, no less seeking
    his consent, the police filmed the interrogation. On
    three separate occasions shortly before the trial, a local
    television station broadcast the film to audiences rang-
    ing from 24,000 to 53,000 individuals. Rideau moved for
    a change of venue, arguing that he could not receive a
    fair trial in the parish where the crime occurred, which
    had a population of approximately 150,000 people.’’
    Skilling v. United States, supra, 
    561 U.S. 379
    . The
    Supreme Court held that Rideau could not receive a
    fair trial because ‘‘[w]hat the people [in the community]
    saw on their television sets . . . was Rideau, in jail,
    flanked by the sheriff and two state troopers, admitting
    in detail the commission of the robbery, kidnapping,
    and murder. . . . [T]o the tens of thousands of people
    who saw and heard it . . . the interrogation in a very
    real sense was Rideau’s trial—at which he pleaded
    guilty. . . . [The court] therefore [did] not hesitate to
    hold, without pausing to examine a particularized tran-
    script of the voir dire, that [t]he kangaroo court pro-
    ceedings trailing the televised confession violated due
    process.’’ (Citations omitted; emphasis in original; inter-
    nal quotation marks omitted.) 
    Id.,
     quoting Rideau v.
    Louisiana, 
    supra,
     725–27.
    The United States Supreme Court also considered
    in Skilling ‘‘two later cases in which media coverage
    manifestly tainted a criminal prosecution,’’ namely,
    Estes v. Texas, 
    381 U.S. 532
    , 
    85 S. Ct. 1628
    , 
    14 L. Ed. 2d 543
     (1965), and Sheppard v. Maxwell, 
    supra,
     
    384 U.S. 333
    , both of which featured media coverage and
    reporting to the extent that the reporters and television
    crews physically overran the courtroom itself, creating
    ‘‘ ‘[b]edlam’ ’’ and a ‘‘ ‘carnival atmosphere’ ’’ around the
    trial. Skilling v. United States, supra, 
    561 U.S. 379
    –80.
    Relying on Murphy v. Florida, 
    supra,
     
    421 U.S. 798
    –99,
    however, the court emphasized in Skilling that its ‘‘deci-
    sions . . . cannot be made to stand for the proposition
    that juror exposure to . . . news accounts of the crime
    . . . alone presumptively deprives the defendant of due
    process. . . . Prominence does not necessarily pro-
    duce prejudice, and juror impartiality, we have reiter-
    ated, does not require ignorance.’’28 (Citations omitted;
    emphasis in original; footnotes omitted; internal quota-
    tion marks omitted.) Skilling v. United States, supra,
    380–81. Accordingly, the court emphasized in Skilling
    that a ‘‘presumption of prejudice . . . attends only the
    extreme case.’’ Id., 381.
    The Supreme Court rejected Skilling’s argument ‘‘that
    [it] need not pause to examine the screening question-
    naires or the voir dire before declaring his jury’s verdict
    void.’’ Id. The court emphasized that ‘‘[i]mportant differ-
    ences separate Skilling’s prosecution from those in
    which [the court has] presumed juror prejudice,’’ con-
    trasting Houston’s population of more than 4.5 million
    with the smaller communities at issue in its other cases,
    particularly Rideau. Id., 381–82; see also footnote 28
    of this opinion. The court observed that, with Houston’s
    ‘‘large, diverse pool of potential jurors, the suggestion
    that [twelve] impartial individuals could not be empan-
    eled is hard to sustain.’’ Skilling v. United States, supra,
    
    561 U.S. 382
    .
    The Supreme Court also considered the nature of the
    media coverage, observing that, ‘‘although news stories
    about Skilling were not kind, they contained no confes-
    sion or other blatantly prejudicial information of the
    type readers or viewers could not reasonably be
    expected to shut from sight. Rideau’s dramatically
    staged admission of guilt, for instance, was likely
    imprinted indelibly in the mind of anyone who watched
    it.’’ 
    Id.,
     382–83. The court also observed that, ‘‘unlike
    cases in which trial swiftly followed a widely reported
    crime . . . over four years elapsed between Enron’s
    bankruptcy and Skilling’s trial. Although reporters cov-
    ered [Enron related] news throughout this period, the
    decibel level of media attention diminished somewhat
    in the years following Enron’s collapse.’’ (Citation omit-
    ted.) Id., 383. The court further determined that Skilling
    was not prejudiced by the ‘‘[well publicized] decision’’
    of a codefendant Enron executive to plead guilty
    because the District Court ‘‘took appropriate steps to
    reduce that risk,’’ such as delaying jury selection pro-
    ceedings by two weeks and expanding voir dire inquir-
    ies to address recent publicity, including any news
    about the codefendant. (Internal quotation marks omit-
    ted.) Id., 384–85. ‘‘Finally, and of prime significance,’’
    the court emphasized that the jury’s verdict in Skilling
    demonstrated the jurors’ impartiality, insofar as they
    found him not guilty ‘‘of nine [insider trading] counts.
    Similarly, earlier instituted [Enron related] prosecu-
    tions yielded no overwhelming victory for the [g]overn-
    ment.’’ Id., 383. Thus, the court concluded that
    ‘‘Skilling’s trial, in short, share[d] little in common with
    those in which [the court] approved a presumption of
    juror prejudice,’’ emphasizing that ‘‘pretrial publicity—
    even pervasive, adverse publicity—does not inevitably
    lead to an unfair trial. . . . In this case . . . news sto-
    ries about Enron did not present the kind of vivid,
    unforgettable information [the court has] recognized as
    particularly likely to produce prejudice, and Houston’s
    size and diversity diluted the media’s impact.’’ (Citation
    omitted; internal quotation marks omitted.) Id., 384.
    The Supreme Court next turned to the actual preju-
    dice claims and examined the voir dire in Skilling to
    consider whether an impartial jury had in fact been
    selected. Id., 385. Emphasizing the customary deference
    given by appellate courts to trial courts’ assessments
    of juror impartiality; see id., 386–87; the court engaged
    in a detailed examination of the juror selection process,
    including the use of individual voir dire in conjunction
    with a ‘‘comprehensive questionnaire drafted in large
    part by Skilling,’’ which was used as an initial screening
    tool ‘‘to identify prospective jurors excusable for cause
    and served as a springboard for further questions put
    to remaining members of the array. Voir dire thus was
    . . . the culmination of a lengthy process.’’ (Internal
    quotation marks omitted.) Id., 388; see id., 389
    (‘‘[i]nspection of the questionnaires and voir dire of the
    individuals who actually served as jurors satisfie[d] [the
    court] that . . . the selection process successfully
    secured jurors who were largely untouched by Enron’s
    collapse’’); id., 395 (The court emphasized the role of
    the individual voir dire process ‘‘to uncover concealed
    bias. This face-to-face opportunity to gauge demeanor
    and credibility, coupled with information from the ques-
    tionnaires regarding jurors’ backgrounds, opinions, and
    sources of news, gave the court a sturdy foundation
    to assess fitness for jury service.’’). The court further
    rejected Skilling’s claims that several specific jurors
    who sat at his trial were biased, noting that he had
    challenged only one of them for cause. See id., 395–99.
    In the wake of Skilling, it has become axiomatic that,
    although ‘‘any [high profile] case will receive significant
    media attention’’ and ‘‘people in general, and especially
    the well-informed, will be aware of it . . . [k]nowledge
    . . . does not equate to disqualifying prejudice. Distin-
    guishing between the two is at the heart of the jury
    selection process.’’ In re Tsarnaev, supra, 
    780 F.3d 15
    ;
    see also State v. Reynolds, supra, 
    264 Conn. 224
    (‘‘[j]urors need not be totally ignorant of the facts and
    issues involved in a criminal trial and the fact that some
    jurors have some prior knowledge about the case does
    not itself constitute identifiable jury prejudice’’ (internal
    quotation marks omitted)). With these principles in
    mind, we now examine the record in this case to deter-
    mine whether it is one in which the ‘‘community’s
    knowledge . . . has . . . crossed from familiarity
    . . . to . . . prejudice’’; In re Tsarnaev, supra, 23;
    mindful that ‘‘the prospect of seating an unbiased jury’’
    is the key to the presumed prejudice inquiry, with the
    actual prejudice inquiry ‘‘turn[ing] on [the] perception
    of the adequacy of the [jury selection] process’’ itself.

    States, supra,

     n.19.
    C
    Presumed Prejudice
    In determining whether prejudice should be pre-
    sumed, we consider the following factors articulated
    by the United States Supreme Court in Skilling, namely,
    (1) ‘‘the size and characteristics of the community in
    which the crime occurred,’’ (2) the nature of the media
    coverage, (3) whether the passage of time has alleviated
    the impact of any prejudicial publicity, and (4) whether
    the jury’s actions and verdict, along with the jury selec-
    tion procedures utilized, were consistent with imposing
    a presumption of prejudice. Skilling v. United States,
    supra, 
    561 U.S. 382
    –83.
    Courts applying the Skilling factors have deemed
    the size and characteristics of the community to be of
    paramount importance. ‘‘The larger the community, the
    more likely that impartial jurors can be found within
    it. . . . And [i]t is well recognized that in a small rural
    community in contrast to a large metropolitan area, a
    major crime is likely to be embedded in the public
    consciousness with greater effect and for a longer time.
    . . . Thus both the size and the character of the coun-
    ty’s population, while not determinative, are factors to
    be considered.’’ (Citation omitted; internal quotation
    marks omitted.) State v. Sowell,

    and In re Tsarnaev, supra, 
    780 F.3d 21
    , New Haven,
    with an urban and suburban population of 846,000, is
    significantly larger than other regions that courts have
    deemed sufficiently populous to permit the selection
    of an impartial jury, even in cases of local, and often
    national, notoriety, particularly when expanded voir
    dire procedures are employed. See, e.g., United States
    v. Philpot,

    , 738, 741 (7th Cir. 2013) (North-

    , 464, 
    951 N.E.2d 903
     (2011) (observing that ‘‘[t]he small size of

    local prejudice’’ in light of its ‘‘just over 10,000 perma-

    among the victim’s family, members of the [overall] jury
    venire, and trial witnesses demonstrate[d] the network
    of social relations connecting this community, of which
    the victim was a valued member, and to which the
    defendant was an outsider’’). The size and diversity of
    New Haven, with its population of 846,000 at the time
    of trial, greatly increase the feasibility of identifying an
    impartial jury, meaning that this Skilling factor weighs
    very strongly in favor of the state, particularly given
    the much smaller populations that have been deemed
    adequate to mitigate the prejudicial effect of substantial
    and adverse pretrial publicity.29
    With respect to media coverage and public aware-
    ness, as a general proposition, even a high volume of
    coverage about a sensational or particularly violent
    crime does not by itself tip this Skilling factor to favor
    a criminal defendant who is the subject of that publicity.

    300 Kan. 1
    , 67, 69, 
    331 P.3d 544

    increased purchases of home security systems]. It can
    hardly help but be so. . . . Yet, overall . . . the pri-
    marily factual tone of the press coverage . . . compen-
    sated for its sheer magnitude, and the second Skilling
    factor did not weigh in favor of presumed prejudice.’’

     (‘‘[o]ne who is
    reasonably suspected [of] murdering [a police officer
    in the line of duty] cannot expect to remain anonymous’’
    (internal quotation marks omitted)). This is particularly
    so, given that the impact of media coverage has become
    increasingly difficult to assess. Unlike the relatively lim-
    ited local television coverage considered by the United
    States Supreme Court in Rideau v. Louisiana, 
    supra,
    373 U.S. 725
    –27, in which the viewership was geographi-
    cally confined and readily ascertainable, we must also
    consider the reality of life in the twenty-first century.
    ‘‘Simply because prospective jurors may have heard
    about a case through media reports does not render
    them incapable of jury service, since, in today’s informa-
    tion age, [when] news of community events [is] dissem-
    inated virtually instantaneously by an ever multiplying
    array of delivery methods, it would be difficult to find
    [twelve] jurors who do not at least have some knowl-
    edge of the facts of an important and tragic incident
    like this one.’’ (Internal quotation marks omitted.) State

    dice in notorious murder case, especially when defen-
    dant was ‘‘relatively unknown outside Puerto Rico’’

    (D.P.R. August 17, 2020) (The court questioned whether
    the First Circuit’s description in 1987 of Puerto Rico
    as ‘‘ ‘a compact, insular community’ ’’ that is ‘‘ ‘highly
    susceptible to the impact of local media’ ’’ remains accu-
    rate given ‘‘[t]he advent of the [I]nternet and social
    media (and other developments) . . . . Like the resi-
    dents of Boston, it is possible that Puerto Ricans now
    ‘obtain their news from a vast array of sources.’ ’’).
    Thus, caution about changing venue is appropriate ‘‘in
    any case that draws significant national attention’’
    because, ‘‘[i]f exposure to a certain level of pretrial
    publicity renders a community presumptively unable
    to convene an impartial jury, then no venue will be
    acceptable, and no trial will be possible . . . .’’ (Inter-

    That having been said, we acknowledge that at least
    some of the coverage in the media in the present case
    went beyond the reporting of even the most disturbing
    facts and, instead, was at times evocative of the ‘‘lynch
    mob mentality’’ or ‘‘[community wide] rush to judg-
    ment’’ identified by the United States Supreme Court
    as being sufficiently prejudicial to trigger a presumption
    of prejudice. (Internal quotation marks omitted.) State
    v. Gribble, supra, 
    165 N.H. 27
    . Commentary from a bipar-
    tisan array of prominent political figures made clear
    the extent to which this case affected the debate about
    criminal justice public policy and, particularly, the
    death penalty. Most graphic were the widely reported
    comments of Senator Prague, who, as we previously
    noted, was a formerly ardent death penalty opponent who
    changed her position on the issue after meeting with
    W, and then stated for the public record—while jury
    selection was ongoing in this case—her widely reported
    view that the defendant should be hanged in a public
    street by his genitalia. Indeed, then Governor M. Jodi Rell
    specifically cited this case in vetoing legislation repeal-
    ing the death penalty. See Connecticut Executive Branch,
    Press Release, Governor Rell Vetoes HB 6578, An Act
    Concerning the Penalty for a Capital Felony (June 5,
    2009), available at https://www.ct.gov/governorrell/
    cwp/view.asp?A=3675&Q=441204 (last visited April 8,
    2021). Similarly, former Governor Dannel Malloy stated
    in his 2010 campaign for office that he would support
    legislation prospectively repealing the death penalty,
    with a prospective only repeal aimed specifically at
    ensuring the executions of the defendant and Hayes.
    In our view, targeted public commentary of this ilk—
    above the line from the comments section and made
    by prominent public officials—is sufficient to tip the
    press coverage Skilling factor in the defendant’s favor,
    even accounting for the twenty-first century reality of
    the omnipresent media coverage of notorious crimi-
    nal cases.
    Turning to the remaining Skilling factors, we agree
    with the defendant that the passage of several years
    from when the home invasion occurred did not, by
    itself, blunt the potentially prejudicial impact of the
    coverage, insofar as this case was tried several months
    after Hayes’ conviction and death sentence, the media
    coverage of which operated to revive any dissipation
    that had taken place. Cf. Skilling v. United States,
    supra, 
    561 U.S. 383
    –85 (passage of four years between
    Enron bankruptcy and trial minimized prejudice to Skil-
    ling, although another Enron executive’s ‘‘[well publi-
    cized] decision to plead guilty shortly before [Skilling’s]
    trial created a danger of juror prejudice’’ that was
    addressed by continuances and enhanced voir dire
    (internal quotation marks omitted)); State v. Gribble,
    supra, 
    165 N.H. 22
    –23 (effect of media coverage on
    home invasion case tried approximately four months
    after verdict in coconspirator’s trial, which had
    ‘‘received substantial publicity,’’ was mitigated because
    defendant pleaded not guilty by reason of insanity and,
    therefore, did not contest most factual allegations).
    Most significant, however, the jury selection process
    used in this case very strongly favors the state with
    respect to whether to presume prejudice. Having denied
    the motion to change venue without prejudice, the trial
    court properly relied on the prospect of Connecticut’s
    attorney led, individual voir dire process to give the
    parties and the court a comprehensive opportunity to
    assess each prospective juror’s familiarity with the case
    and ability to render an impartial verdict; that process
    far exceeded the more truncated process deemed con-
    stitutionally adequate in Skilling.30 See, e.g., Skilling
    v. United States, supra, 
    561 U.S. 387
    –89 (court led,
    individual voir dire over five hour period following sub-
    mission of questionnaires). Indeed, the trial court pru-
    dently enhanced the utility of this extensive and
    searching individual voir dire process by awarding each
    of the parties forty peremptory challenges, which
    exceeded the minimum of thirty mandated in capital
    cases by § 54-82h (a). Coupled with the size and diver-
    sity of New Haven’s population, this extensive process
    strongly supports a conclusion that there was no pre-
    sumptive prejudice in this case.31 See In re Tsarnaev,
    supra,

    voir dire process in Boston Marathon bombing case);

    the trial court also prudently left open the possibility
    of changing the venue should the individual voir dire
    process indicate that an impartial jury could not be
    empaneled in New Haven. See State v. Reynolds,
    supra, 224.
    As the California Supreme Court recently observed
    in upholding the denial of a second change of venue in
    the Scott Peterson death penalty trial,32 which was a
    case of similar national notoriety arising from a hus-
    band’s murder of his pregnant wife, the ‘‘publicity . . .
    generated’’ in this case, ‘‘like the trials of O.J. Simpson,
    the Manson family, and any number of other so-called
    trials of the century before them, was intrinsic to the
    case, not the place,’’ particularly given ‘‘the explosion
    of cable television and the Internet as sources of infor-
    mation, facilitating nationwide coverage of the case,’’
    meaning it was ‘‘speculation to suppose [the] results of
    jury selection would be any different anywhere else.’’
    (Emphasis in original; internal quotation marks omit-
    ted.) People v. Peterson, supra, 
    10 Cal. 5th 440
    . Put
    differently, the endless and instant flow of informa-
    tion—and in some cases disinformation—enabled by
    twenty-first century media, does not stop at the political
    boundaries of our judicial districts. ‘‘Instead, in a [high
    profile] case such as this one, provided a sufficiently
    large pool is available . . . the better answer is not to
    change venue . . . but to rigorously vet potential
    jurors to screen out those tainted and irrevocably biased
    by pretrial publicity, to find [twelve], plus alternates,
    who can decide only on the evidence admitted at trial.’’
    Id., 441. We conclude, therefore, that the defendant
    has not surmounted the ‘‘extremely high’’ bar; (internal
    quotation marks omitted) State v. Robinson, supra, 
    303 Kan. 76
    ; see also Skilling v. United States, supra, 
    561 U.S. 381
    ; necessary to establish the existence of pre-
    sumptive prejudice in this case, insofar as the other
    Skilling factors function to outweigh the inflammatory
    nature of the publicity that attended this case with
    respect to the possibility of empaneling an impartial
    jury.
    D
    Actual Prejudice
    We next consider whether pretrial publicity resulted
    in actual prejudice in this case.33 This requires us to
    examine the record of jury selection to determine
    whether it ‘‘adequately detect[ed] and defuse[d] juror
    bias.’’ Skilling v. United States, supra, 
    561 U.S. 385
    .
    Particularly in cases with extensive pretrial publicity
    and notoriety, individual voir dire, which is mandated
    by article four of the amendments to the Connecticut
    constitution; see, e.g., Rozbicki v. Huybrechts, supra,
    
    218 Conn. 392
     and n.2; is critical to ensure the selection
    of jurors who are sufficiently impartial to serve. See
    Commonwealth v. Toolan, supra, 
    460 Mass. 468
     (failure
    to conduct individual voir dire regarding exposure to
    pretrial publicity denied defendant his right to fair trial
    given risk of prejudice occasioned by ‘‘small, socially
    interconnected community’’ in Nantucket and extensive
    pretrial publicity).
    As a matter of both well established Connecticut and
    federal constitutional law, ‘‘[n]o [hard and fast] formula
    dictates the necessary depth or breadth of voir dire.
    . . . Jury selection . . . is particularly within the prov-
    ince of the trial judge. . . .
    ‘‘When pretrial publicity is at issue, primary reliance
    on the judgment of the trial court makes [especially]
    good sense because the judge sits in the locale where
    the publicity is said to have had its effect and may base
    her evaluation on her own perception of the depth and
    extent of news stories that might influence a juror. . . .
    Appellate courts making after-the-fact assessments of
    the media’s impact on jurors should be mindful that
    their judgments lack the [on the spot] comprehension
    of the situation possessed by trial judges.
    ‘‘Reviewing courts are properly resistant to second-
    guessing the trial judge’s estimation of a juror’s impar-
    tiality, for that judge’s appraisal is ordinarily influenced
    by a host of factors impossible to capture fully in the
    record—among them, the prospective juror’s inflection,
    sincerity, demeanor, candor, body language, and appre-
    hension of duty. . . . In contrast to the cold transcript
    received by the appellate court, the [in the moment]
    voir dire affords the trial court a more intimate and
    immediate basis for assessing a venire member’s fitness
    for jury service.’’ (Citations omitted; internal quotation
    marks omitted.) Skilling v. United States, supra, 
    561 U.S. 386
    –87; see also State v. Griffin, 
    251 Conn. 671
    ,
    710, 
    741 A.2d 913
     (1999) (‘‘[t]he trial court is vested
    with wide discretion in determining the competency of
    jurors to serve’’); State v. Pelletier, supra, 
    209 Conn. 572
     (describing trial court’s ‘‘broad discretion’’ with
    respect to ‘‘determining the credibility of prospective
    jurors and their ability to be impartial’’).
    In assessing for actual prejudice, we are cognizant
    that a lengthy voir dire process is frequently necessary
    to seat a sufficient number of impartial jurors and that a
    lengthy duration is not, by itself, indicative of ‘‘pervasive
    prejudice permeating through the jury pool,’’ insofar as
    ‘‘a jury selection process of several weeks in length is
    not unusual in either contemporary or historical terms.
    [M]ajor cases have been known to require six weeks
    or more before the jury is seated.’’ (Footnote omitted;
    internal quotation marks omitted.) In re Tsarnaev,
    supra, 
    780 F.3d 25
    –26; see 
    id., 26
     (‘‘it defies logic to
    count the efforts the [D]istrict [C]ourt has taken to
    carefully explore, and eliminate, any prejudice as show-
    ing the existence of the same’’ (emphasis in original)).
    This is particularly so in death penalty cases, which add
    significant lines of questioning to the juror qualification
    process.34 See 
    id.,
     26 and n.15.
    Accordingly, we now turn to a detailed analysis of
    the jury selection process in the present case. Our juror
    by juror35 analysis to determine whether the trial court
    empaneled an impartial jury focuses on the jurors who
    actually deliberated at trial and sentencing. See, e.g.,
    State v. Gould, 
    322 Conn. 519
    , 531, 
    142 A.3d 253
     (2016)
    (‘‘[p]rejudice is assessed with reference to the jurors
    who [found] the defendant [guilty] because [t]he consti-
    tutional standard of fairness requires [only] that a defen-
    dant have a panel of impartial, indifferent jurors’’
    (internal quotation marks omitted)).
    For the sake of relative brevity, our review does not
    extensively consider the jurors’ personal background
    histories, focusing instead on the portions of voir dire
    relevant to the major issues in this appeal, namely, the
    extent of their exposure to pretrial publicity and the
    effect of that exposure on their case knowledge and
    impartiality. Although the death penalty is no longer at
    issue in this case, we include in footnotes a review of
    each juror’s views on that topic, insofar as that subject
    would have strongly informed the parties’ decision
    whether to accept a particular juror.36 Finally, we note
    that each selected juror repeatedly expressed his or her
    ability (1) to be fair and impartial, (2) to understand
    and apply the reasonable doubt burden of proof as to
    each element of each charged offense, along with the
    presumption of innocence, and (3) not to be swayed
    by sympathy for the P family or to be affected emotion-
    ally after viewing disturbing crime scene or autopsy
    photographic evidence. None of the jurors who were
    asked whether they had participated in the P family
    memorial or charitable activities responded in the affir-
    mative. None of the jurors who were asked had changed
    their home security habits as a result of this case.
    Finally, the trial court instructed each selected juror not
    to talk about the case with anyone or to do independent
    research, and to avoid media coverage of the case dur-
    ing the time between jury selection and the start of
    trial. We now turn to an examination of each juror’s
    individual voir dire.37
    1
    Review of Jurors
    a
    M.N.
    The first regular juror selected was M.N., a physi-
    cian.38 When the trial court asked M.N. whether he
    could be fair and impartial with respect to both the
    guilt and penalty determinations, he stated: ‘‘[C]learly,
    I’ve heard of this case, and, when it first happened, I
    read about it in the news and saw some stories on TV.
    Nonetheless, I realize that things may not always be the
    way they are represented in the media, and I understand
    that my charge would be to evaluate things based solely
    on the evidence, evidence that would be presented dur-
    ing court, and I will try my hardest to do that.’’ M.N.
    had read about the case in the New York Times and
    on Google News, and had ‘‘occasionally’’ seen stories
    about it on television news. When asked about what
    he knew about the case, M.N. stated: ‘‘I think that the
    home was, I guess, the term has been used in the media,
    the home was invaded, three of the four individuals
    were raped and killed, and the fourth individual was
    beaten, and then the house was put to fire.’’ M.N. was
    familiar with Cheshire, having lived in a nearby town,
    but did not know the area where the crime occurred.
    M.N.’s last exposure to information about the case was
    during Hayes’ trial; he was aware that Hayes was con-
    victed but did not know the sentence imposed. Both
    parties accepted M.N. without challenge.39
    b
    T.A.
    The second regular juror chosen was T.A., a college
    student studying criminal justice and social work who
    interns with a program that assists sex offenders with
    transitioning from incarceration to the community. T.A.
    obtained most of his news, including knowledge about
    this case, from television and stated that none of that
    coverage would keep him from being fair and impartial,
    particularly because he viewed the media as having ‘‘a
    tendency of twisting and turning things . . . .’’ When
    asked to rate how frequently he had heard about this
    case on a scale of one to ten, he rated it between five
    and seven. T.A. did not make a point of following the
    coverage and had not read any of the books written
    about the case. When questioned about his case knowl-
    edge, T.A. stated that ‘‘a murder occurred in Cheshire,
    and it was pertaining to the family members that, you
    know, one person or two people, you know, were the
    culprits of a murder.’’ T.A. believed that ‘‘three or four’’
    people were killed in the incident and that two perpetra-
    tors had been arrested. T.A. also knew that the other
    person who was arrested had been convicted and sen-
    tenced to death. T.A. was familiar with Cheshire but
    not the street where the crime took place. T.A. stated
    that none of that knowledge would keep him from being
    fair and impartial because being a juror ‘‘pertains to
    evidence and the law, so you can’t really manipulate
    evidence or the law’’; he informed defense counsel that
    he would consider this case on its own facts because
    he did not ‘‘know [Hayes’] case. I don’t know what . . .
    evidence . . . was presented to the jury to make [it]
    decide that . . . .’’ He had not had ‘‘big’’ discussions
    about the case with other people, having talked about
    it once with his brother; T.A. did not remember his
    brother’s opinion, which he emphasized would not
    affect his decision making as a juror in any event. Both
    parties accepted T.A. as a juror.40
    c
    T.M.
    The third regular juror selected was T.M., an investi-
    gator for a state agency working on ‘‘family issues,’’
    whose responsibilities required her to testify in court
    regularly.41 T.M. testified that she followed local televi-
    sion news, along with some Internet news, but did not
    read the New Haven Register ‘‘much.’’ T.M. had not
    followed the news about this case ‘‘consistently’’ and
    had no impressions about it other than that ‘‘innocent
    people’’ had ‘‘suffered . . . .’’ She had not read any
    books written about this case. When asked what she
    knew about the case, T.M. stated that, from what she
    had ‘‘been subjected to probably in the news and then
    hearing it at work or wherever,’’ her impression was
    that ‘‘the woman was followed from Stop and Shop to
    her residence. I guess they waited outside and, at some
    point . . . they kind of scoped out the neighborhood,
    the area. Later that night, they broke into a basement
    where [W] was, beat him up, tied him up, went upstairs
    or proceeded upstairs and raped the young girls, [J],
    beat them up, killed them, murdered them, and set the
    house on fire, tried to escape. Or, excuse me, missing
    the part where I guess she went to the bank to take
    out ‘x’ amount of dollars or, you know, she was being
    robbed.’’ T.M. emphasized, however, that she did not
    have any preconceived ideas about the defendant’s guilt
    or innocence and that she could put her knowledge
    aside and keep an open mind because she has ‘‘to hear
    both sides.’’ T.M. was aware that the defendant had
    been caught at the scene, which indicated to her that
    he was at the very least ‘‘a suspect at this point,’’
    although he ‘‘may’’ or ‘‘may not’’ have committed the
    crimes. T.M. did not see W’s appearance on The Oprah
    Winfrey Show, although she had seen him on the news.
    Her impression was that W was ‘‘suffering from a great
    loss’’ but that she could still assess his credibility objec-
    tively.42 T.M. had heard some discussions about Hayes’
    trial and death sentence but did not believe that should
    affect the defendant’s trial because he is a ‘‘[d]ifferent
    individual,’’ and she did not ‘‘know the facts,’’ including
    ‘‘what part’’ the defendant had played, or even ‘‘if he
    played a part.’’ T.M. had no preconceived notion as
    to the sentence that the defendant should receive if
    convicted of a capital offense, and she did not know
    anything about him personally.
    T.M. also testified that, prior to voir dire, two or three
    of the other prospective jurors had discussed the case,
    opining that ‘‘the police should have been there . . .
    right away or should have done something that day.
    That the two men [who] participated and that they’re
    evil, things like that.’’ Those jurors thought that the
    defendant and Hayes were ‘‘caught red-handed, so [they
    were] guilty,’’ with one stating that the defendant should
    receive life imprisonment. None of those prospective
    jurors personally knew the P family or any of their
    friends or colleagues. T.M. testified that these discus-
    sions would not keep her from being fair and impartial
    and deciding the case on the evidence heard in court.
    T.M. also had discussed the case with family and
    friends because it was a ‘‘hot topic’’ in the New Haven
    area; although none of them had expressed a desire to
    have the defendant executed, neither had any expressed
    a belief that he was innocent. T.M. had never expressed
    an opinion personally to anyone about the defendant’s
    guilt or potential sentence. Her impression was that
    ‘‘[t]here’s different opinions’’ within the community,
    acknowledging that many people believed that the
    defendant should be executed. T.M. emphasized that
    none of the community members’ views would influ-
    ence her decision in any way and that she could with-
    stand any pressure that she might feel because, ‘‘at
    trial, you can’t listen to someone who’s not, you know,
    involved in the issue or, you know, here every day, so,
    no. I would have to go based on the facts that . . . I
    learn during the trial. It wouldn’t have anything to do
    with it.’’ T.M. said that she routinely pushes other peo-
    ple’s opinions aside to reach decisions in both her pro-
    fessional and personal lives. T.M. expressed confidence
    in her ability to stand her ground and to consider other
    people’s opinions during a difficult deliberation. Both
    sides accepted T.M. as a juror.43
    d
    K.A.
    The fourth regular juror selected was K.A., a physi-
    cian.44 When asked about her familiarity with the case,
    K.A. replied that she ‘‘under[stood] a family was lost
    that day’’ and that ‘‘a family, a woman and her daughters
    were murdered in their own homes,’’ as well as that ‘‘I
    don’t remember the details, but I know that there was
    also sexual abuse to some of them, including the daugh-
    ters.’’ K.A. had not followed the case closely or read
    anything about it recently.
    K.A. had not discussed the case recently, although
    her husband ‘‘ha[d] brought it up’’ to her ‘‘[i]ntermit-
    tently,’’ in the context of his own religious ‘‘struggle[s]’’
    with the death penalty and his sympathy for the P family.
    K.A. further stated that this conversation had taken
    place in the context of the Hayes verdict and that her
    husband was ‘‘a bit disappointed with himself’’ for being
    ‘‘comfortable’’ with Hayes’ death sentence. K.A. did not
    know enough about Hayes’ case to take a position dur-
    ing that conversation. K.A. stated that her husband
    believed that the defendant was guilty, as well, but that
    his opinion had ‘‘[n]ot much’’ effect on her—and he
    would ‘‘back [her] up on that,’’ as she listens to him
    ‘‘[c]onstructively’’ and will make up her own mind.
    When questioned by defense counsel, K.A. stated that
    the fact that she was a mother to two young children
    would not keep her from being fair and impartial.
    K.A. averred that she was proud of the criminal justice
    system because ‘‘it’s part of what’s so great about this
    country altogether,’’ as ‘‘it is pretty noble that we try
    to give everybody the opportunity to . . . make their
    case . . . for what’s happened rather than just assum-
    ing . . . these are [the] facts or this is how the facts are
    presented and . . . clearly this person must be guilty.
    I think it’s ambitious and noble that we go beyond that
    and try to make it a systematic presentation of what
    the facts truly were rather than the circumstantial evi-
    dence.’’ Both the state and the defendant accepted K.A.
    as a juror.45
    e
    V.K.
    The fifth regular juror selected was V.K., a mental
    health counselor who works primarily with children
    and adolescents.46 V.K. testified several times that she
    would not have any problem being fair and impartial
    to both sides, despite the fact that her sister is a victim’s
    advocate who works with sexual assault victims. V.K.
    testified that she was living in Spain when the murders
    happened, and she had not heard anything about the
    case at that time. When asked what she knew about
    the case, V.K. stated that ‘‘it happened in Cheshire,’’
    ‘‘[t]wo daughters and . . . the mother were murdered,’’
    and ‘‘the father I guess was there, but he survived. Um,
    and their house was burnt down. And I guess there
    [were] two suspects.’’ V.K. was aware that the first
    suspect had been tried and convicted, and she
    believed—but did not ‘‘know’’—that he had been sen-
    tenced to death. V.K. had not followed Hayes’ trial or
    other local news, choosing to follow only ‘‘important
    national news’’ and ‘‘international news . . . .’’ V.K. did
    not know anything about the defendant, favorable or
    otherwise, including what his involvement was in the
    crime. V.K. was not aware that books had been written
    about this case.
    V.K. had not discussed the case with friends, family,
    or coworkers, although she perceived that everyone in
    the community believed that the defendant was guilty.
    She would, however, be able to ‘‘make a sound judgment
    based on the evidence that was presented to me’’ and
    to ‘‘stand by what I chose,’’ despite the beliefs of other
    community members. V.K. would not let the communi-
    ty’s apparent wishes factor into her decision making,
    believing that her professional background left her
    suited to resist peer pressure. She would make her
    decision based solely on the evidence in the courtroom,
    ‘‘[m]ostly because I don’t know anything of the case
    . . . so I really would need to hear all of the evidence
    to make a sound judgment.’’ V.K. would be ‘‘honored
    if [she were] asked’’ to serve on the jury because she
    believed it to be an ‘‘important’’ civic obligation for her
    to ‘‘do my part as a citizen.’’ She acknowledged that,
    while waiting, she had discussed the case with some
    of the other prospective jurors, who had made ‘‘[m]ostly
    negative’’ comments about it, opining that they ‘‘could
    never be . . . unbiased [toward] it and that they felt
    [the defendant] was guilty.’’ V.K., however, did not
    express any opinion about this case in those discus-
    sions. V.K. was accepted as a juror.47 See footnote 46
    of this opinion.
    f
    M.B.
    The sixth regular juror selected was M.B., a retired
    municipal social services employee. M.B. learned about
    this case by reading the newspaper. When asked what
    she knew about it, M.B. stated: ‘‘What I read is that
    there were two people who broke into a home and
    assaulted [J] and [W] and set the house on fire, and the
    people who were in the home at the time, only one
    person escaped, and the other three perished. . . .
    [W]hat I know about it is what I’ve read. . . . I don’t
    know exactly what I think about it . . . .’’ M.B. was
    aware that the defendant had been arrested ‘‘directly
    after he . . . left the house’’ and knew from reading
    the newspaper that he had an accomplice named Hayes
    who had already been tried, convicted and, she thought,
    sentenced to death. Both parties accepted M.B. as a
    regular juror.48
    g
    L.C.
    The seventh regular juror selected was L.C., an archi-
    tect employed by a university. L.C. had heard about
    this case but did not watch television news and typically
    just skimmed local newspapers for stories about her
    employer. When asked what she knew about the case,
    L.C. stated that ‘‘there was a murder in Cheshire,’’ but
    she could not ‘‘exactly remember the date . . . and I
    know the name of the family from seeing it, you know,
    hearing it.’’ L.C. had not read any books about the case.
    L.C. knew that there was another trial related to the
    case because she passed the courthouse each day on
    her way to work, and she was ‘‘racking my brains at
    lunchtime’’ to remember that ‘‘there was a conviction,
    but I don’t remember the sentence.’’ She had flipped
    past, but had not read, stories about the Hayes trial;
    she contrasted her lack of awareness of this case to
    that of another homicide that she had followed more
    closely because it had happened at the university where
    she worked and had ‘‘affected us so much.’’ When ques-
    tioned by defense counsel, L.C. explained that she could
    be impartial because ‘‘I haven’t followed [the case] that
    much . . . compared to most people in Connecticut
    I’m probably not very knowledgeable about it. And . . .
    it’s what our legal system is. I mean, that is what one
    is supposed to do, and . . . I am a very ethical person.’’
    She presumed that the defendant was innocent, and
    she was ‘‘embarrassed to admit’’ that she did not recog-
    nize him, had not heard his name before, and could not
    ‘‘remember the name of the first guy . . . .’’
    L.C. had briefly discussed the case with her husband
    in July, 2007, because they were ‘‘horrified . . . that
    these deaths had happened, but, other than that . . .
    we really haven’t talked about it,’’ including the verdict
    or penalty in Hayes’ case. She did not have any conver-
    sations with other coworkers, friends, or family mem-
    bers about the case. L.C. assumed that the community
    ‘‘want[ed] some sort of retribution for the deaths of
    . . . a woman and her two children,’’ but believed it
    was her ‘‘professional duty’’ to withstand any pressure
    during or after the trial.
    L.C. stated that the other prospective jurors did not
    discuss the case while they were waiting, other than
    complaining about logistics and the inconvenience of
    waiting. Both parties accepted L.C. as a juror.49
    h
    R.F.
    The eighth regular juror selected was R.F., a munici-
    pal employee with a college degree in public health.
    R.F. had been exposed to ‘‘bits and pieces over the
    course of . . . several months and years’’ about the
    case from television coverage. R.F. had ‘‘heard’’ about
    the case and ‘‘read [about it in] the newspaper’’ and
    very briefly while looking at books at Barnes & Noble
    bookstore; he had been aware of it from the day of the
    incident when it was discussed in the breakroom at
    his job, as well as in subsequent discussions with his
    coworkers and his family about current events. When
    asked whether he had a ‘‘preconceived idea’’ about the
    defendant’s guilt from that coverage, he acknowledged
    that ‘‘[p]robably, I would think he was guilty from what
    I’ve read in the paper and what I’ve seen on TV,’’ but
    he also had no ‘‘preconceived idea’’ of an appropriate
    punishment. R.F.’s last reading about the case con-
    cerned Hayes’ trial and subsequent suicide attempt.
    When asked to provide a narrative of what he knew
    about the case, R.F. stated that ‘‘the victims were at
    . . . a food store of some sort and they were followed
    home and then they broke in [at] some point later on,’’
    and ‘‘tied them up. . . . I think they raped the wife
    . . . and then they took her to the bank, I believe, to
    try and withdraw money. They came back. He tried to
    start a fire or did start a fire. They killed three of them,
    and then they tried to drive away. The police stopped
    them.’’ R.F. did not know which perpetrator had started
    the fire or purchased the gasoline, and he could not
    remember what was said in the newspaper about it; he
    did not ‘‘know the details’’ of which parts were perpe-
    trated by the defendant. R.F. was aware of Hayes’ name
    and trial and the fact that he was found guilty and
    sentenced to death, as well as that the defendant and
    Hayes were arrested together, but, when questioned
    about whether that would affect his impartiality or deci-
    sion in this case, emphasized repeatedly that he ‘‘would
    just ignore that’’ and that it ‘‘wouldn’t affect’’ him.
    R.F. stated that, despite previous discussions with
    family and coworkers about the ‘‘gruesome’’ nature of
    the case, he did not ‘‘really remember’’ any opinions
    about what should be done to the defendant or Hayes,
    and he emphasized that he personally would ‘‘come in
    with an open mind’’ and continue to presume that the
    defendant was innocent. R.F. also understood that his
    decision had to be based on the evidence presented in
    court rather than ‘‘[p]ast history’’ such as newspapers
    or conversations, describing himself as ‘‘pretty open-
    minded,’’ despite his exposure to coverage of the case
    in newspapers and on television, and conversations
    with his parents, who thought it was ‘‘a pretty much
    open and shut case . . . .’’
    R.F. believed that the community was ‘‘angry’’ about
    the case, and he indicated that some of his coworkers
    had expressed opinions about it. R.F. had never posted
    anything on social media about the case. Acknowledg-
    ing that it would be ‘‘difficult,’’ R.F. stated that he could
    reach a verdict independently, having made ‘‘unpopular
    decisions’’ in the past that had made people ‘‘very angry
    with me,’’ and believing that his friends and family
    would not hold his decision against him. R.F. had not
    heard other waiting, prospective jurors talk about the
    case, other than complaining about how long the voir
    dire process was taking. It did not bother him that two
    potential jurors had left crying in his presence because
    he could ‘‘understand them getting emotional about it,
    but it didn’t really affect me.’’ Both the state and the
    defendant accepted R.F. as a juror.50
    i
    L.K.
    The ninth juror selected was L.K., a university
    employee with a masters degree in psychology. L.K. had
    not ‘‘read about the trial . . . or the case or anything
    in a while.’’ When asked to provide a narrative of what
    she knew about the case, which was a product of read-
    ing newspapers, CNN’s website, and watching local tele-
    vision news, L.K. stated: ‘‘[F]rom what I’ve heard, there
    were two men who went into a house, and I believe
    the—the father, who is [W], was, I think, asleep in
    another room, and they came in, and I’m not sure if
    they had, you know, hit him or something happened, but
    then they ended up—the—the mother—I don’t know
    if the girls woke up, too, but they ended, like, at—that
    was, like, in the evening, I think.
    ‘‘And then the next day I know that . . . the wife
    and mom went to the bank to withdraw a sum of money,
    and I think that she told the tellers there that—I don’t
    know if she told them details or that she was being
    held captive or whatever, but she indicated something
    to them, and they did report that to the police.
    ‘‘And then I know that there are charges—I think
    there were charges of sexual assault as well, and then
    I know that the house was burned down and [W] did
    manage to escape, but that the other three died in the
    fire.’’ L.K. testified that she was ‘‘sketchy’’ about the
    details of the arrests of Hayes and the defendant. She
    did not ‘‘recall’’ who had performed specific acts in the
    house. The last thing she read about the case was that
    Hayes had been tried and convicted, and she ‘‘believe[d]
    he was sentenced to death.’’ L.K. had not seen W’s
    appearance on The Oprah Winfrey Show; she had seen
    him elsewhere on television and only had the ‘‘general
    impression’’ that he ‘‘was a man who lost his family.’’
    When asked whether she could decide the case based
    solely on the evidence presented in court, given that
    some of it might be consistent with what she knew and
    some might be different, L.K. replied that she could do
    that, along with affording the defendant his presump-
    tion of innocence. She understood that ‘‘serving on a
    jury and being part of this is . . . just about what is
    presented here,’’ and she would ‘‘come in with the
    understanding that [the] knowledge that I’ve heard and
    learned or opinions that I may have come or thought
    about are left . . . outside because I can only evaluate
    or think about what is shown to me in . . . this court-
    room.’’ When asked whether the Hayes’ verdict would
    affect her thinking, L.K. observed that, ‘‘in an ideal
    world, you know, we would have people who knew
    nothing and just walked in . . . but that’s not the world
    we live in. And, so, you need to take knowledge and
    prior things that you know and realize that this trial is
    not for the person, that person was convicted, that was
    what happened with him, this is for someone else. It’s
    an important thing to evaluate critically. . . . [M]y goal
    in coming in and being a juror would be to just listen
    to what I am told here.’’ L.K. acknowledged that, based
    on the prior coverage and Hayes’ verdict, before coming
    to court and hearing the instructions, she would have
    felt that the defendant ‘‘probably was guilty but that,
    you know, he hasn’t been tried.’’ She was ‘‘comfortable’’
    that she could put aside any ‘‘preconceived ideas’’ that
    she had about the case.
    L.K. had spoken about the case over the last few
    years with friends, family, and coworkers because ‘‘it’s
    been a very big case’’ and believed that ‘‘the community
    wants justice . . . . [Y]ou know it was a horrific
    crime.’’ She believed that the general feeling was that
    ‘‘whoever did that should absolutely be punished for
    it.’’ L.K.’s decision would not be influenced by what she
    thought the community would want, emphasizing: ‘‘I
    don’t want to be chosen, but . . . being a part of this
    jury . . . it’s an important thing to do. I don’t think
    that I could walk away or feel at rest with myself if
    . . . I didn’t do it the way it was supposed to be done.
    . . . [T]hese are big decisions that have to be made and
    . . . this was a horrific crime, and this is someone’s
    life that we’re . . . sitting here discussing, and I think
    that it would be very important for me to do it in the
    way that is the law and that has to be done. I couldn’t
    rest with myself if I didn’t.’’ Both the state and the
    defendant accepted L.K. without challenge.51
    j
    S.H.
    The tenth juror selected was S.H., a truck mechanic.
    S.H. read the New Haven Register and the Meriden
    Record-Journal daily but did not remember the last
    thing he had read or seen on television news about the
    case. S.H. did not regularly search the Internet for news
    or use it otherwise. He did not know that jury selection
    was going on in this case until he reported for jury duty.
    When asked what he knew about the case, S.H. stated
    that he had ‘‘read the early headlines and maybe a
    little bit of the follow-up on that’’ in July, 2007. S.H.
    ‘‘underst[ood] a couple of guys broke into a house . . .
    I guess they tried to make it look like a robbery, I
    believe, and they killed some people.’’ He believed that
    three people had died and that two had been arrested.
    S.H. thought that ‘‘a mother and a daughter [were killed]
    but [was] not sure beyond that.’’ He did not know how
    the victims died or the respective roles of the individuals
    arrested. S.H. did not know about the Hayes trial. S.H.
    did not know the defendant’s name or background. He
    had not discussed the case with anyone and had no
    sense of what the community wanted done with the
    case. S.H. was familiar with Cheshire but had never
    been near the crime scene. Both parties accepted S.H.
    as a juror.52
    k
    J.H.
    The eleventh juror selected was J.H., a corporate
    compliance officer and insurance fraud investigator.
    J.H. subscribed to the Meriden Record-Journal but did
    not read it every day—she received it primarily to help
    her parents keep up on the obituaries. When asked what
    she knew about the case, J.H. stated that she had ‘‘read
    somewhat about it in the newspaper’’ but ‘‘was not
    really following the case, and that it was a terrible
    tragedy.’’ Providing an additional narrative, J.H. recalled
    that ‘‘two individuals broke into the home of [W], and
    subsequently his wife and two daughters were killed.’’
    When asked about whether she knew anything about
    a trip to the bank, J.H. remembered having ‘‘read some-
    thing about going to the bank,’’ but that was ‘‘unclear
    to [her].’’ She did not know how the deaths occurred
    but remembered reading ‘‘something’’ about allegations
    of sexual assault. J.H. did not know how the suspects
    were caught. She knew that the case of the other suspect
    was ‘‘settled recently’’ and that he was found guilty, but
    she did not ‘‘know any more than that,’’ including the
    punishment he received. She also did not know anything
    about the different activities of the two men in connec-
    tion with the crime. When asked whether she knew
    anything about the defendant’s background, J.H.
    ‘‘recall[ed] something about a father, but . . . nothing
    really more than that.’’ She had not seen W on television.
    J.H. did not read any books about the case or ever call
    into a radio talk show to discuss it. She was a ‘‘little
    bit’’ familiar with Cheshire but did not know the location
    of the crime scene.
    J.H. had discussed the case with family members
    when it first happened, ‘‘not at length, but just to be
    very sympathetic.’’ She did not discuss it with cowork-
    ers. She thought the community wanted ‘‘[j]ustice’’ but
    ‘‘couldn’t presume to know’’ what that meant in this
    case. J.H. stated that she was ‘‘used to controversy’’ and
    that the feelings of the community ‘‘wouldn’t change
    my vote or my opinion’’ because a juror hearing evi-
    dence for several months is in a different position than
    the general public. J.H. emphasized that she would con-
    fine her decision to the evidence presented in court
    and would not consider the ‘‘fair amount of sympathy’’
    that she was sure she would feel. Both parties accepted
    J.H. as a juror.53
    l
    C.A.
    The twelfth regular juror selected was C.A., a tennis
    coach. C.A. testified that he had heard ‘‘[n]ot a lot, but
    some’’ about the case. He read the New York newspa-
    pers ‘‘[f]airly regularly,’’ and the New Haven Register
    ‘‘periodically,’’ as well as watched local television news
    and saw some news on the Internet. C.A. had seen news
    stories about the case but had not followed the case
    regularly or made a point of learning about it. C.A. knew
    there was ‘‘a lot of attention, a lot of media coverage,’’
    but did not ‘‘remember . . . any specific details that
    stood out because it was hard to piece kind of all of it
    together . . . .’’ When asked what he knew about the
    events, C.A. recalled ‘‘[o]nly that it was a . . . very,
    very heinous crime’’ and that ‘‘[t]here was a home break-
    in, people were killed, a wife and daughters were killed,
    the house was set on fire, and [that] relatively, as far
    as I know, is it.’’ He did not know how the house was
    set on fire or where the suspects were arrested. C.A.
    had heard the defendant’s name before in the news but
    did not have any impression of him from that coverage.
    C.A. could not remember the last thing he had heard
    about the case. He was not familiar with the neighbor-
    hood in Cheshire where the crime occurred. C.A. was
    aware that there had been another trial but did not
    know the name of the other defendant or the result of
    his case.
    In stating his ability to presume the defendant inno-
    cent and to decide the case based only on the evidence
    in court, C.A. recognized that ‘‘the case itself hasn’t
    come to trial,’’ and ‘‘everybody deserves a fair shot in
    the court, not necessarily in the court of opinion or in
    the court of television, newspaper, media, whatever.’’
    C.A. described himself as ‘‘a facts person,’’ stating that
    ‘‘I want to hear everything before I make judgments.’’
    C.A. testified that the other prospective jurors had
    not discussed the case while they were waiting. He did
    not know what the community wanted to happen with
    the case and had not discussed it with his family or
    friends. C.A. suggested that, ‘‘maybe, the people in
    Cheshire who are close to the situation and have knowl-
    edge of it would . . . want a certain verdict, but I don’t
    know if I can answer that for the community at large,
    basically, you know, make a general statement like
    that.’’ C.A. stated that, if he did come to learn of those
    opinions, they would not affect his decision in this case.
    Both parties accepted C.A. as a juror.54
    2
    Actual Prejudice Analysis
    We conclude that the defendant suffered no actual
    prejudice from the extensive pretrial publicity about
    this case, as both the jury and the voir dire process by
    which it was selected compared very favorably to that
    which the United States Supreme Court deemed consti-
    tutionally acceptable in Skilling v. United States, supra,
    
    561 U.S. 358
    . First, the individual voir dire process did
    not consist of blind acceptances of prospective jurors’
    assurances of impartiality but involved a lengthy and
    thorough probing of their responses to questions by the
    state, the defendant, and the trial court. The defendant
    did not exhaust his peremptory challenges until the voir
    dire of the backup alternate jurors—after the regular
    and alternate jurors had been selected—and did not
    challenge for cause any juror who actually deliberated
    in this case. We also ‘‘note that the trial court took
    unusually thorough measures to ensure the jury’s con-
    tinued impartiality through the use of extensive daily
    admonishments counseling the avoidance of any public-
    ity.’’ State v. Crafts, supra, 
    226 Conn. 261
    .
    Although some of the jurors in this case expressed
    abstract sympathy for W and the P family based on what
    had happened to them—none of which was disputed
    at trial—these statements paled in contrast to those
    made by certain jurors deemed impartial in Skilling,
    several of whom had been personally affected by the
    Enron collapse. See Skilling v. United States, supra, 
    561 U.S. 396
     (noting that District Court properly rejected
    challenge for cause in crediting juror’s statement that
    he would have no trouble telling coworker who had
    lost 401 (k) funds in Enron collapse of not guilty verdict,
    despite fact that juror personally believed Enron’s col-
    lapse was product of ‘‘ ‘greed’ ’’ and that ‘‘corporate
    executives, driven by avarice, ‘walk a line that stretches
    sometimes the legality of something’ ’’); id., 397 (District
    Court did not commit manifest error in seating juror
    who ‘‘said she was angry about Enron’s collapse and
    that she, too, had been forced to forfeit [her] own 401
    (k) funds to survive layoffs’’ because she ‘‘made clear
    during voir dire that she did not personally blame Skil-
    ling for the loss of her retirement account,’’ thought
    she could be fair and impartial, and had ‘‘not [paid]
    much attention to [Enron related] news . . . [so] she
    quite honestly did not have enough information to know
    whether Skilling was probably guilty’’ (internal quota-
    tion marks omitted)); id. (District Court properly cred-
    ited multiple assurances of impartiality from juror who
    ‘‘wrote on her questionnaire that [Skilling] probably
    knew [he] [was] breaking the law,’’ after she stated that
    ‘‘she did not know what [she] was thinking when she
    completed the questionnaire’’ (internal quotation marks
    omitted)). As the United States Supreme Court
    observed, ‘‘[j]urors . . . need not enter the box with
    empty heads in order to determine the facts impartially.
    It is sufficient if the juror[s] can lay aside [their] impres-
    sion[s] or opinion[s] and render a verdict based on the
    evidence presented in court.’’ (Internal quotation marks
    omitted.) Id., 398–99.
    Consistent with the deference that we afford to the
    trial court’s assessment of juror impartiality, pre-Skil-
    ling decisions from this court also support the conclu-
    sion that there was no actual prejudice in this case. For
    example, State v. Pelletier, supra, 
    209 Conn. 564
    , arose
    from the highly publicized Purolator Armored Car rob-
    bery in Waterbury, during which three guards were
    shot to death. See 
    id.,
     567–68. In Pelletier, this court
    concluded that the trial court did not deprive the defen-
    dant of a fair trial by declining to transfer his felony
    murder case out of Waterbury for a new trial after
    a successful appeal from the judgment of conviction
    rendered at his first trial. 
    Id.,
     568–69. The court rejected
    the defendant’s claim that ‘‘the best evidence of actual
    prejudice is found in the results of the voir dire examina-
    tion of 381 venirepersons. Of those examined, the defen-
    dant claim[ed] that 199 were excused for cause because
    of prior knowledge of the case. [The court concluded,
    however, that this] fact alone . . . [did] not establish
    actual jury prejudice.’’ Id., 570. The court emphasized
    that ‘‘[e]ach prospective juror was thoroughly and
    extensively examined. The parties fully explored the
    level and effects of each prospective juror’s exposure
    to the publicity concerning the defendant. . . . While
    slightly more than 50 percent of the prospective jurors
    had prior knowledge of the case that would affect their
    ability to be impartial, of the twelve jurors and two
    alternates actually selected, none had substantial
    knowledge of the case or preconceived notions of the
    defendant’s guilt. It is clear that [q]ualified jurors need
    not . . . be totally ignorant of the facts and issues
    involved. . . . Notably, none of the jurors or alternates
    selected knew of the defendant’s prior conviction. . . .
    [T]here was no connection between the pretrial public-
    ity and actual jury prejudice and, therefore . . . the
    trial court did not abuse its discretion in denying the
    defendant’s motion to transfer the prosecution.’’ (Cita-
    tions omitted; emphasis added; internal quotation
    marks omitted.) Id., 570–71. In particular, the court
    deferred to the trial court’s decision to credit the state-
    ments of ‘‘eight venirepersons . . . that their knowl-
    edge of the defendant’s conviction [at his first trial]
    would not affect their ability to be impartial,’’ particu-
    larly when ‘‘[t]hroughout the voir dire the trial court
    excused for cause those venirepersons it believed could
    not be impartial.’’ Id., 572.
    Similarly, in the infamous ‘‘ ‘woodchipper murder
    case’ ’’; State v. Crafts, supra, 
    226 Conn. 258
    ; this court
    held that there was no actual prejudice requiring a new
    trial because ‘‘the voir dire . . . reveal[ed] that,
    although many prospective jurors were familiar with
    the fact of the defendant’s arrest and of his first trial,
    most had only a vague recollection of any particular
    accounts of the crime.’’ Id., 259. This court also
    observed that the defendant in Crafts had failed to
    exhaust his peremptory challenges after unsuccessful
    challenges for cause and had had the opportunity to
    explore fully each juror’s exposure to pretrial publicity;
    id., 259–60; and that ‘‘the trial court took unusually
    thorough measures to ensure the jury’s continued
    impartiality through the use of extensive daily admon-
    ishments counseling the avoidance of any publicity.’’
    Id., 261.
    Sister state case law similarly makes clear the defer-
    ence appellate courts afford to trial courts’ assessments
    of juror impartiality during voir dire during notorious
    trials. See, e.g., People v. Avila, supra, 
    59 Cal. 4th 508
    ,
    513 (local radio show broadcast during jury selection
    urging death verdict and recruitment of ‘‘ ‘stealth
    juror’ ’’ did not require change of venue because trial
    court properly used voir dire to determine whether
    prospective jurors had listened to program, and review
    of voir dire ‘‘fully support[ed] the trial [court’s] estima-
    tion of the jury’s impartiality’’); State v. Carr, 
    supra,
    300 Kan. 76
     (The court held that there was no actual
    prejudice in a death penalty trial, which arose from
    a crime spree culminating in a home invasion with a
    quadruple homicide and sexual offenses, because,
    ‘‘despite widespread pretrial publicity, an unbiased jury
    had been selected in Wichita [Kansas]. Eight of the
    [twelve] jurors eventually seated in the defendants’ trial
    held no prior opinions on guilt. The four who admitted
    to forming such opinions ultimately said that they could
    set their opinions aside.’’); State v. Gribble, supra, 
    165 N.H. 26
    –28 (no actual prejudice from pretrial publicity
    in home invasion, double homicide case given that trial
    court credited jurors’ assurances that they could decide
    case based solely on evidence, despite fact that ‘‘almost
    all of the prospective jurors were aware of the crimes
    before jury selection,’’ and all ‘‘sixteen seated jurors
    reported knowing about the crimes prior to jury selec-
    tion, and most acknowledged that they had seen or
    heard media accounts of the case,’’ even when trial
    court had denied five challenges for cause to seated
    jurors with some having previously discussed case with
    others); People v. Cahill, 
    2 N.Y.3d 14
    , 36–37, 40–41, 
    809 N.E.2d 561
    , 
    777 N.Y.S.2d 332
     (2003) (upholding denial
    of venue change in case of husband accused of poison-
    ing his wife after she was comatose from beating he
    inflicted on her, despite facts that 86 percent of prospec-
    tive jurors, including eight of twelve who sat, had heard
    of case and that 52 percent ‘‘came to court with an
    opinion as to [the] defendant’s guilt or innocence . . .
    [because] the voir dire successfully culled out jurors
    who may have been biased by pretrial publicity’’).
    As the defendant points out, the appropriately lengthy
    jury selection process in this case was not always the
    smoothest of sailing. A number of prospective jurors
    lost their composure at times, with some crying in open
    court or making menacing comments about or toward
    the defendant, with one, for example, calling him a
    ‘‘[k]iller, asshole,’’ after she was excused from jury ser-
    vice. These comments were a serious breach of the
    decorum expected in our state’s courthouses. Neverthe-
    less, these outbursts, although inappropriate and unfor-
    tunate, did not deprive the defendant of a fair trial
    because the trial court queried any prospective jurors
    who had witnessed them about any effect that the out-
    bursts might have had on their impartiality. See State
    v. Ziel, 
    197 Conn. 60
    , 65–67, 
    495 A.2d 1050
     (1985) (com-
    mentary in jury room by venire members that defendant
    was guilty did not require excusal of entire panel, and
    trial court properly credited testimony of two jurors
    that they could remain impartial and decide case based
    solely on evidence in court, despite having heard those
    comments). Given the extensive voir dire conducted in
    this case, we defer to the trial court’s assessment of
    the credibility of these jurors in light of their answers
    that they could remain fair and impartial, particularly
    insofar as only one of the prospective jurors who wit-
    nessed an outburst, R.F.—who saw two women leave
    crying—actually sat as a juror in this case, and the
    defendant did not challenge him—or any other regular
    juror—for cause. See part I C 1 h of this opinion. Accord-
    ingly, we conclude that the pretrial publicity did not
    result in actual jury prejudice that deprived the defen-
    dant of a fair trial.
    E
    Whether the Trial Court Improperly Denied the
    Defendant’s Challenges for Cause
    The defendant next claims that the trial court abused
    its discretion by denying his challenges for cause to
    twelve potential jurors,55 thus depriving him of a fair
    trial. He argues that they could not judge his case fairly
    and impartially, and the trial court improperly placed
    ‘‘undue reliance on [those jurors’] own assessments—
    expressed with varying degrees of certainty—that they
    could be fair and impartial.’’ In response, the state cites,
    among other cases, State v. Campbell, 
    328 Conn. 444
    ,
    
    180 A.3d 882
     (2018), and State v. Esposito, 
    223 Conn. 299
    , 
    613 A.2d 242
     (1992), and contends, inter alia, that
    the defendant cannot prevail on these claims because
    he did not exhaust his forty peremptory challenges until
    after the twelve main and six alternate jurors had been
    seated, and, most important, no juror who decided his
    guilt was one whom he had challenged for cause. We
    agree with the state and conclude that any error with
    respect to challenges for cause was harmless because
    none of the challenged jurors actually decided his guilt.
    ‘‘The Connecticut constitution guarantees a criminal
    defendant the right to exercise peremptory challenges
    in the selection of his jury. Conn. Const., [amend. IV];
    see also General Statutes §§ 54-82g and 54-82h. . . .
    [W]e agree with numerous other courts throughout the
    nation that it is reversible error for a trial court to force
    an accused to use peremptory challenges on persons
    who should have been excused for cause, provided the
    party subsequently exhausts all of his or her peremptory
    challenges and an additional challenge is sought and
    denied.’’56 (Internal quotation marks omitted.) State v.
    Esposito, supra, 
    223 Conn. 313
    ; see State v. Campbell,
    supra, 
    328 Conn. 476
    ; State v. Kelly, 
    256 Conn. 23
    , 31,
    
    770 A.2d 908
     (2001).
    ‘‘[I]t is implicit in Esposito that, in determining
    whether the denial of a for cause challenge was poten-
    tially harmful, this court considers whether an identifi-
    able, objectionable juror actually served on the jury
    that decided the case, not whether the composition of
    the jury would have been different in the absence of
    the claimed error.’’ State v. Ross, 
    269 Conn. 213
    , 232,
    
    849 A.2d 648
     (2004); see id., 233 (failure to seek and
    exercise additional peremptory challenge against spe-
    cific juror after exhaustion of peremptory challenges
    rendered harmless any previous improper denial of for
    cause challenge because ‘‘the defendant was not forced
    to accept an incompetent or objectionable juror after
    his peremptory challenges had been exhausted’’). Put
    differently, ‘‘the general rule is that an improper grant
    or denial of a for cause challenge is not prejudicial
    unless the defendant shows that the ruling resulted in
    an identifiable, objectionable juror actually serv[ing] on
    the jury that decided the case . . . .’’ (Internal quota-
    tion marks omitted.) State v. Gould, supra, 
    322 Conn. 530
    . ‘‘Prejudice is assessed with reference to the jurors
    who convicted the defendant because [t]he constitu-
    tional standard of fairness requires [only] that a defen-
    dant have a panel of impartial, indifferent jurors. . . .
    The right to challenge is the right to reject, not to select a
    juror of the defendant’s preference.’’ (Citations omitted;
    internal quotation marks omitted.) Id., 531. But cf id.,
    531–32 (violation under Batson v. Kentucky, 
    476 U.S. 79
    , 
    106 S. Ct. 1712
    , 
    90 L. Ed. 2d 69
     (1986), is ‘‘a limited
    exception’’ to prejudice rule).
    We conclude that the defendant cannot prevail on
    his for cause challenge claims because no challenged
    juror actually sat to deliberate in this case. It is undis-
    puted that the defendant did not challenge for cause
    any of the twelve main jurors who actually deliberated
    on this case; see part I C of this opinion; and none of
    the alternates or backup alternates, some of whom had
    been challenged for cause, was required to participate.
    Accordingly, we need not reach the merits of these
    claims because any error in the trial court’s rulings on
    these identified challenges for cause was harmless due
    to the fact that none of those jurors deliberated with
    the jury that decided his guilt.57
    II
    CLAIMS ARISING FROM HAYES’ LETTERS
    The defendant next raises several claims arising from
    the state’s disclosure, after the close of evidence, of
    approximately 130 pages of letters written by Hayes
    while he was incarcerated, which the Department of
    Correction (department) had intercepted before they
    reached their intended recipient, an unidentified
    woman in North Carolina. In addition to claiming that
    the state’s disclosure of the letters after the close of
    evidence violated Brady v. Maryland, 
    supra,
     
    373 U.S. 83
    , the defendant also contends that the trial court
    improperly denied his motions (1) for a continuance to
    assess the information therein, and (2) to reopen the
    evidence because the trial court had found that the
    letters were not sufficiently trustworthy to render them
    admissible as statements against penal interest under
    § 8-6 (4) of the Connecticut Code of Evidence.58 The
    defendant argues that Hayes’ letters would have sup-
    ported his theory of the case, namely, that he did not
    intend for anyone to be killed, insofar as Hayes essen-
    tially admitted in the letters that he was the ‘‘master-
    mind’’ of the invasion of the P family home, and also
    confessed to raping, torturing, and murdering seventeen
    other women and girls. In response, the state contends
    that the trial court properly exercised its discretion to
    deny the various motions given its predicate determina-
    tion that the letters were not admissible as statements
    against penal interest, which also rendered them imma-
    terial for Brady purposes. The state further argues that
    any error was harmless because admitting the letters in
    their entirety into evidence would have been extremely
    prejudicial to the defendant because they contained
    graphic depictions of sexual assaults—including the
    assault of M that the defendant denied committing—
    and descriptions of joint efforts between the defendant
    and Hayes to plan and execute the crimes. We agree
    with the state and conclude that the trial court did not
    abuse its discretion in denying the defendant’s motions
    for a continuance, mistrial, or to reopen the evidence
    on the basis of the disclosure of the letters after the
    close of evidence.
    The record reveals the following additional relevant
    facts and procedural history. After the close of evi-
    dence, on October 7, 2011, the state provided the defen-
    dant with 132 pages of handwritten letters from Hayes
    to an unidentified woman who lived in North Carolina,
    which the department had intercepted and given to the
    prosecutor. On October 11, 2011, which was the day of
    closing arguments, the defendant moved for a continu-
    ance, claiming that he needed time to assess the letters
    because they contained information that was exculpa-
    tory to him, as, in addition to vividly describing the
    details of what had transpired in the P residence, Hayes
    confirmed his leadership role when he stated: ‘‘The [P]
    home invasion was a dry run in the partnership between
    [the defendant] and myself. I do now realize had we
    gotten away, I would have killed [the defendant]. He
    was not even close to being worthy of my partnership.
    His sloppiness and lack of control would have been my
    downfall . . . .’’ The defendant also argued that the
    letters provided evidence of other crimes that estab-
    lished Hayes’ modus operandi, given his claim therein
    that he had committed seventeen other murders by
    strangulation across the northeastern United States,
    each of which was preceded by a sexual assault. The
    trial court denied the motion for a continuance, stating
    that, although it would have granted one during a court
    trial, ‘‘we have the jury that’s ready to go, and [its] time
    has to be considered, too, and it’s a balancing act.’’
    The trial court further observed that the letters did not
    appear exculpatory to the defendant. The trial court
    did, however, agree to delay submitting the case to the
    jury for deliberations until the following day, in order
    to give the defendant and the court an additional oppor-
    tunity to review the letters in more detail later that day.59
    The next day, the defendant moved for permission
    to reopen the defense, initially proposing to offer Hayes’
    testimony to establish his lack of availability to testify
    as a predicate to the admissibility of the letters.60 The
    defendant also suggested that the postevidence disclo-
    sure of the letters, which appeared to have been written
    between August and September of 2011, could form the
    basis for a motion for a mistrial, although he agreed
    that the prosecutor had not been dilatory about provid-
    ing the letters. Defense counsel reiterated his desire
    for a continuance because he ‘‘had very little time to
    actually go through [the letters] and figure out [their]
    evidentiary potential,’’ observing that Hayes’ ‘‘depraved
    letter . . . outlines details perceived by him and writ-
    ten by him as to the events that occurred in the [P]
    home; perhaps, more importantly, as he details other
    crimes he’s committed, he develops [a modus operandi]
    that is similar to this crime.’’ Defense counsel again
    argued that the language describing the P home invasion
    as a ‘‘dry run’’ and indicating that Hayes would have
    killed the defendant had they escaped ‘‘clearly demon-
    strates that Hayes was the mastermind and the leader,’’
    which was ‘‘exculpatory in rebutting the state’s theory
    that [the defendant] was the leader.’’ Defense counsel
    also argued that Hayes’ claimed history of having raped
    and strangled seventeen women ‘‘would indicate that,
    unbeknownst to [the defendant] . . . when they
    entered that house . . . Hayes had an agenda that he
    [had not] exposed to [the defendant], which was to
    further his [modus operandi] and to further his
    depraved actions that he had done in the past.’’61 Coun-
    sel argued that it was ‘‘fundamentally unfair’’ that, given
    the ‘‘clear . . . exculpatory information’’ in the letters,
    he did not have time to investigate ‘‘information of this
    type,’’ including the identity of the woman and any
    questions that might have been posed to Hayes in
    responsive letters, which might provide context for his
    statements. The state objected to the defendant’s
    motion to reopen, arguing that the letters were hearsay
    that were ‘‘unequivocally, undeniably . . . not reli-
    able . . . .’’
    The trial court treated the defendant’s motions as
    ones for both a continuance and to reopen, and denied
    both, relying on this court’s decision in Wood v. Bridge-
    port, 
    216 Conn. 604
    , 
    583 A.2d 124
     (1990). The court
    determined that there was nothing in the letters that
    would lead to a ‘‘miscarriage of justice’’ should the
    evidence not be reopened. Assuming that Hayes would
    assert the fifth amendment privilege and thus be
    unavailable as a witness, the trial court nevertheless
    determined that the letters were not admissible as state-
    ments against penal interest under § 8-6 (4) of the Con-
    necticut Code of Evidence because the statements
    therein were unreliable, as Hayes’ descriptions of the
    seventeen homicides were ‘‘couched in terms that
    would be very difficult to allow corroboration because
    no dates are given, no times [are given], no locations
    are given, what he did with the bodies is not given.’’
    Most important, the trial court emphasized that the
    defendant ‘‘cherry-picks’’ certain portions of the letters,
    while ignoring others that were ‘‘quite damning’’ to him,
    with the letters in their entirety being ‘‘the seal of [the
    defendant’s] doom’’ were they to be admitted into evi-
    dence.62 Specifically, the trial court observed that the
    letters would not benefit the defendant, even if Hayes
    were to be deemed ‘‘the leader in this horrendous enter-
    prise,’’ given statements therein that the defendant him-
    self had admitted prior killings, Hayes stated that they
    had planned to kill all of the occupants of the P house,
    Hayes vividly described watching the defendant sexu-
    ally assault M anally, and Hayes said that it was the
    defendant who had poured the gasoline. The trial court
    further concluded that the probative value of the letters
    was outweighed by their prejudicial effect because lead-
    ership was not relevant to the elements of the crimes,
    with the content of the letters ultimately being harmful
    with respect to supporting the defendant’s claim of lack
    of intent.63 The trial court then denied the defendant’s
    motion for a mistrial based on prejudice caused by the
    late production of the letters, concluding that the state
    had turned them over immediately upon receipt.
    The defendant’s various claims arising from the dis-
    closure of the Hayes letters after the close of evidence
    are evaluated under similar, well established legal stan-
    dards, and we consider them together. With respect to
    the defendant’s request to reopen the evidence, we note
    that, ‘‘[i]n any ordinary situation if a trial court feels that,
    by inadvertence or mistake, there has been a failure to
    introduce available evidence upon a material issue in
    the case of such a nature that in its absence there is a
    serious danger of a miscarriage of justice, it may prop-
    erly permit that evidence to be introduced at any time
    before the case has been decided. . . . Whether . . .
    a trial court will permit further evidence to be offered
    after the close of testimony in a case is a matter resting
    in the sound discretion of the court. . . . Such a
    reopening should not be permitted if it would result in
    substantial prejudice to a party.’’ (Citations omitted;
    internal quotation marks omitted.) Wood v. Bridgeport,
    supra, 
    216 Conn. 606
    ; see, e.g., State v. Carter, 
    228 Conn. 412
    , 420–21, 
    636 A.2d 821
     (1994); State v. Dunbar,

    247 Conn. 962
    , 
    724 A.2d 1126
     (1999). In considering
    ‘‘whether the trial court acted within its broad discre-
    tion in rejecting the defendant’s request for permission
    to introduce [evidence] after the defendant had rested
    his case,’’ we consider the admissibility of the proffered
    evidence, as well as ‘‘the specific circumstances of the
    defendant’s request, including the state’s interest in an
    orderly trial process, the potential for jurors to have
    placed undue emphasis on the evidence had it been
    admitted, and the nature of the evidence.’’ State v. Car-
    ter, supra, 425; see id., 422.
    It is likewise well established that the ‘‘determination
    of whether to grant a request for a continuance is simi-
    larly within the discretion of the trial court. . . . The
    court, in exercising its discretion, may weigh various
    factors in considering a request for a continuance,
    including the likely length of the delay . . . the impact
    of delay on the litigants, witnesses, opposing counsel
    and the court . . . the perceived legitimacy of the rea-
    sons proffered in support of the request . . . [and] the
    likelihood that the denial would substantially impair
    the defendant’s ability to defend himself . . . . In the
    event that the trial court acted unreasonably in denying
    a continuance, the reviewing court must also engage
    in harmless error analysis.’’ (Citations omitted; internal

    assault victim’s jeans given the lack of evidence of
    semen at the scene, the likely length of the delay for
    the testing, the lack of evidence that testing was possi-
    ble given the age of the exhibit, and the fact that the
    defendant was not prejudiced because he could ‘‘argue
    to the jury that the state, which bore the burden of
    proof, had presented no scientific evidence connecting
    him to the crime, and he specifically highlighted the
    lack of testing on the jeans. The defendant made that
    argument with the knowledge that, even if he was con-
    victed, he probably would be granted a new trial if the
    test results proved exculpatory.’’).
    Finally, ‘‘[a]lthough the remedy of a mistrial is permit-
    ted under the rules of practice, it is not favored. [A]
    mistrial should be granted only as a result of some
    occurrence upon the trial of such a character that it is
    apparent to the court that because of it a party cannot
    have a fair trial . . . and the whole proceedings are
    vitiated. . . . If curative action can obviate the preju-
    dice, the drastic remedy of a mistrial should be avoided.
    . . . On appeal, we hesitate to disturb a decision not
    to declare a mistrial. The trial judge is the arbiter of
    the many circumstances [that] may arise during the
    trial in which his function is to [ensure] a fair and just
    outcome. . . . The trial court is better positioned than
    we are to evaluate in the first instance whether a certain
    occurrence is prejudicial to the defendant and, if so,
    what remedy is necessary to cure that prejudice. . . .
    The decision whether to grant a mistrial is within the
    sound discretion of the trial court.’’ (Internal quotation
    marks omitted.) State v. Guilbert, 
    306 Conn. 218
    , 270–
    71, 
    49 A.3d 705
     (2012).
    ‘‘The law governing the state’s obligation to disclose
    exculpatory evidence to defendants in criminal cases
    is well established. The defendant has a right to the
    disclosure of exculpatory evidence under the due pro-
    cess clauses of both the United States constitution and
    the Connecticut constitution. . . . In order to prove a
    . . . violation [of Brady v. Maryland, 
    supra,
     
    373 U.S. 83
    ], the defendant must show: (1) that the prosecution
    suppressed evidence after a request by the defense; (2)
    that the evidence was favorable to the defense; and (3)
    that the evidence was material. . . .
    ‘‘[E]vidence known to the defendant or his counsel,
    or that is disclosed, even if during trial, is not considered
    suppressed as that term is used in Brady. . . . Even if
    evidence is not deemed suppressed under Brady
    because it is disclosed during trial, however, the defen-
    dant nevertheless may be prejudiced if he is unable to
    use the evidence because of the late disclosure. . . .
    Under these circumstances, the defendant bears the
    burden of proving that he was prejudiced by the state’s
    failure to make the information available to him at an
    earlier time.’’ (Citations omitted; internal quotation
    marks omitted.) State v. Guilbert, supra, 
    306 Conn. 271
    –72; see 
    id.,
     272–74 (belated disclosure of surveil-
    lance video recording did not deprive defendant of fair
    trial because, ‘‘even without the video recording, the
    defense was able to show inconsistencies between the
    eyewitness’ descriptions of the defendant and the
    shooter,’’ defense was able to ask ‘‘generally whether
    the police officers had provided [the] witnesses with
    information about the defendant’s appearance,’’ and ‘‘a
    reasonable juror might have concluded that the video
    recording corroborated some of the eyewitness tes-
    timony’’).
    Having reviewed the letters in their entirety, we con-
    clude that the defendant’s various claims arising from
    Hayes’ letters lack merit. Even if we assume, without
    deciding, that the letters would have been admissible
    as dual inculpatory statements against Hayes’ penal
    interest; see Conn. Code Evid. § 8-6 (4);64 there is noth-
    ing therein that is in any way exculpatory or directly
    supports the defendant’s theory that Hayes was the
    ringleader and that the defendant’s role was subservient
    to Hayes—even if that were relevant to the elements
    of the crimes charged. At most, the letters—including
    Hayes’ statement that he would have killed the defen-
    dant had they gotten away—indicate that the invasion
    of the P home was a joint venture. Indeed, substantial
    portions of the letters directly undercut in graphic detail
    certain theories of defense proffered at trial, namely,
    that the defendant did not engage in anal intercourse
    with M and that it was Hayes who had poured the
    gasoline before setting the house on fire.65 Thus, we
    agree with the trial court’s observation that the Hayes
    letters likely would have been ‘‘the seal of [the defen-
    dant’s] doom’’ by both reinforcing the basis for a guilty
    verdict and laying the groundwork for the existence of
    several aggravating factors that the state needed to
    prove to obtain a death verdict during the penalty phase.
    Accordingly, we conclude that there was no miscarriage
    of justice or prejudice as a result of the late disclosure
    of the letters, and the trial court did not abuse its discre-
    tion in denying the defendant’s motions for a mistrial,
    to reopen the evidence, or for a continuance.
    III
    BRADY CLAIMS ARISING FROM VARIOUS CHESHIRE
    POLICE COMMUNICATIONS
    The defendant next claims that the state violated his
    due process rights under Brady v. Maryland, 
    supra,
    373 U.S. 83
    , by failing to disclose to trial counsel
    recordings of numerous Cheshire Police Department
    communications. The claims arising from these commu-
    nications fall into three categories: (1) six communica-
    tions concerning the police response to the home
    invasion, (2) a police communications log contained in
    an e-mail received in January, 2008, by C.H.-R., who is
    J’s sister, and (3) two communications relevant to the
    state of mind and demeanor of both Hayes and the
    defendant at the time of their arrests. The defendant
    argues that the state’s failure to disclose these commu-
    nications deprived him of his right to a fair trial because
    they would have (1) ‘‘strongly supported the defendant’s
    theory that, because of their woefully inadequate
    response to the 911 call from the Bank of America, the
    Cheshire police were motivated by guilt, anger, and
    embarrassment to undermine the credibility of the
    exculpatory parts of his police statements,’’ (2)
    ‘‘strongly supported the defense theory that . . .
    Hayes was the mastermind of the murders and that the
    defendant, stunned by Hayes’ statements and actions
    during the crime, was slow to process and react appro-
    priately to them,’’ and (3) ‘‘constituted powerful excul-
    patory evidence of the defendant’s exhaustion and
    disorientation when arrested and when he waived his
    Miranda rights and gave his police statements.’’ We
    address each Brady claim in turn.
    A
    Additional Relevant Facts and Procedural History
    The record reveals the following additional facts and
    procedural history relevant to the defendant’s Brady
    claims. Robert Sage, an inspector with the prosecutor’s
    office, coordinated the discovery in this case, including
    collecting evidence from the police and bringing it to
    the prosecutors. That material was later distributed by
    the prosecutor to defense counsel as a discovery file,
    the contents of which were memorialized in a letter
    from the prosecutor. Shortly after the home invasion,
    Sage contacted Vignola, Cheshire’s detective captain,
    and asked him to preserve any records relating to the
    investigation, including audio recordings. Vignola
    accommodated that request by directing Michael Win-
    ters, the Cheshire Police Department’s information
    technology coordinator, to capture all communications
    contained in the department’s recording systems from
    the incident, starting with the initial call until the end
    of the incident.66
    In August, 2011, shortly before trial, the defendant
    moved for disclosure and examination of the state’s
    evidence, including exculpatory and impeachment evi-
    dence, pursuant to Brady and the rules of practice.
    The defendant filed an additional disclosure motion on
    August 18, 2011. After a hearing on August 22, 2011, the
    trial court granted both motions, with defense counsel
    acknowledging that the state had conducted this case as
    an open file case and given the defendant all requested
    material to that point. Subsequently, on August 25, 2011,
    defense counsel sent a letter to the prosecutor, which,
    inter alia, (1) observed that a compact disc (CD) that
    had been provided to the defendant of recorded Chesh-
    ire police communications ‘‘contains only select calls’’
    and asked the state to provide all Cheshire and state
    police communications recorded on July 23, 2007, from
    9 a.m. through 1 p.m., and (2) sought ‘‘all documentation
    related’’ to any review of the police response on July 23,
    2007, in light of the ‘‘questions and widespread criticism
    surrounding’’ it. The state subsequently advised the
    defendant that it had provided him with all preserved
    communications. In a letter dated September 19, 2011,
    defense counsel responded that his review of the CD
    that had been provided identified at least one call miss-
    ing from the written log of communications; he also
    specifically requested ‘‘the action review’’ that depart-
    ment policy required following a response of the special
    response team. The record does not include the state’s
    response to that letter. The case then proceeded to trial.
    While this appeal was pending, the defendant’s appel-
    late counsel learned from reading a Hartford Courant
    article that certain Cheshire Police Department commu-
    nications had not been turned over to trial counsel, or
    heard or publicly disclosed prior to trial.67 On August
    29, 2014, the defendant filed in this court a motion for
    augmentation and rectification of the record relating
    to those recordings. The defendant sought a hearing
    pursuant to State v. Floyd, 
    253 Conn. 700
    , 732, 
    756 A.2d 799
     (2000) (Floyd hearing),68 to establish that the state
    had failed to disclose to the defendant’s trial counsel
    recordings of these communications. The defendant
    argued that this failure to disclose violated Brady
    because those communications were evidence that sup-
    ported a defense theory that the police response in this
    case was inadequate. Evidence of an inadequate police
    response would have supported his attempts to attack
    the credibility of various police witnesses who had chal-
    lenged the veracity of the defendant’s statement to the
    police, and also would have ‘‘front-loaded’’ a strategy
    for mitigation in the anticipated penalty phase of the
    trial.69 We referred this motion to the trial court for
    action.
    On September 24, 2014, the state notified the defen-
    dant’s appellate counsel of the existence of additional
    recordings that had not been produced to counsel,
    which were discovered by Cheshire town employees
    after the defendant filed his first motion for augmen-
    tation and rectification of the record. On November 13,
    2015, the defendant filed a second motion for augmen-
    tation and rectification of the record related to those
    additional calls.
    The trial court held a three day Floyd hearing on the
    defendant’s motions.70 In advance of the hearing, the
    state and the defendant stipulated to the existence of
    the recordings of numerous communications from July
    or August of 2007 that had not been disclosed to the
    defendant’s trial counsel prior to trial in 2011 and had
    been provided to appellate counsel for the first time
    in November, 2014. The parties stipulated that those
    recordings were true and accurate copies and should be
    marked as exhibits at the Floyd hearing.71 After hearing
    testimony from Sage, counsel, and Winters; see footnote
    66 of this opinion; the trial court found that the CDs
    were not turned over as a result of an ‘‘error in transmis-
    sion,’’ which was likely attributable to the sheer volume
    of evidence in this case. The trial court found that it
    was uncontested that ‘‘the three police calls described
    in paragraph four on page nine of the August 19, 2014
    motion . . . were not disclosed to the defense.’’72 We
    address the content of these communications in detail
    in part III C of this opinion. See also footnotes 82
    through 84 of this opinion.
    The parties disputed, however, the existence of a
    communication that was described in paragraph one
    on page eight of the August 19, 2014 motion for augmen-
    tation, namely, the call log that C.H.-R. claimed to have
    received in an e-mail. After considering testimony from
    C.H.-R. and her husband, W.R., about this e-mail, the
    trial court found that its existence had not been proven
    by a fair preponderance of the evidence. Consistent
    with our previous denial of relief in a subsequent motion
    for review, we now turn to the merits of the defendant’s
    Brady claims.
    B
    Claims Arising from the E-mail Described by C.H.-R.
    We begin with the defendant’s claim that the trial
    court improperly found that he had failed to prove the
    existence of a call log that established the presence of
    a police officer at the P residence when Hayes and J
    returned from the bank in the Pacifica, which had been
    relayed to C.H.-R., who is J’s sister, in an e-mail that
    she received in January, 2008. The defendant first
    argues that the existence of the call log was established
    by the highly credible testimony of C.H.-R. and her
    husband, W.R., and corroborated by both the ‘‘consis-
    tent and highly suspicious pattern by the police of with-
    holding or mischaracterizing critical police calls’’ and
    ‘‘the improbability’’ that numerous Cheshire police offi-
    cers had not ‘‘arrived at the P residence in time to
    observe the Pacifica returning there.’’ The defendant
    also argues that the trial court improperly required him
    to prove the existence of the call log by a preponderance
    of the evidence, contending that, under § 9-1 (a) of the
    Connecticut Code of Evidence,73 a party need only make
    a prima facie showing of the authenticity of an exhibit
    to the court for purposes of admissibility. Finally, the
    defendant argues that the trial court abused its discre-
    tion by sustaining the prosecution’s objection under
    § 7-1 of the Connecticut Code of Evidence,74 which gov-
    erns the admission of lay opinion testimony, to defense
    counsel’s question at the Floyd hearing to W.R. about
    whether the e-mail ‘‘appear[ed]’’ to him ‘‘to be a docu-
    ment that could have been created by a nonpolice or like
    a layperson who was not involved in the response . . . .’’
    In response, the state assumes the credibility of C.H.-
    R. and W.R. but contends that their testimony neverthe-
    less does not establish the existence of the call log or
    the e-mail in which it was contained. The state also
    cites, among other cases, State v. Thompson, 
    305 Conn. 412
    , 
    45 A.3d 605
     (2012), cert. denied, 
    568 U.S. 1146
    , 
    133 S. Ct. 988
    , 
    184 L. Ed. 2d 767
     (2013), and argues that the
    trial court properly applied the preponderance of the
    evidence standard in determining whether the call log
    or e-mail existed as a predicate factual matter. Finally,
    the state contends that the trial court did not abuse its
    discretion in sustaining its objection to W.R.’s testimony
    about the appearance of the e-mail because it was not
    a proper subject for lay witness opinion testimony. We
    agree with the state and conclude that the trial court
    properly applied the preponderance of the evidence
    standard and concluded that the defendant had not
    established the existence of the communication at
    issue.
    The record reveals the following additional relevant
    facts and procedural history. In his August 29, 2014
    motion for augmentation and rectification of the record,
    the defendant claimed that the state had failed to pro-
    duce a police communication that C.H.-R. had received
    by e-mail in January, 2008, and that she subsequently
    discussed during an appearance on Katie Couric’s tele-
    vision show that aired on August 19, 2013. The defen-
    dant averred that that communication, as described by
    C.H.-R., ‘‘establishes that ‘there actually was a police
    officer at [J’s] home watching her come back to the
    house and pull into the driveway,’ ’’ describing ‘‘ ‘her
    car [as] a silver Chrysler Pacifica [that] is now entering
    the driveway and the garage door is going up and the
    car is pulling in . . . .’ ’’
    At the Floyd hearing, C.H.-R. testified that she and
    her parents had remained in contact with the Cheshire
    police because they had concerns about the police
    response to the home invasion and were angry when
    the Cheshire town manager publicly commended the
    police on television. C.H.-R. testified that, in early Janu-
    ary, 2008, she received an e-mail that contained what
    appeared to be a log of communications between the
    officers before that information was ultimately released
    to the public. C.H.-R. stated that the call log contained
    the times and written descriptions of various communi-
    cations between the responding officers. One particular
    item that distressed C.H.-R. was a notation in the log
    that Cheshire police officers were present and had wit-
    nessed the Pacifica returning to the P family residence,
    leading her to conclude that officers were present at
    the house for approximately forty-five minutes before
    Hayes and the defendant fled the scene and that the
    officers could have prevented the deaths of J, H, and
    M. C.H.-R. testified that the log document in the e-mail
    did not have any logos or markings indicating that it
    had originated from either the Cheshire Police Depart-
    ment or the prosecutor’s office. C.H.-R. did not know
    who sent the e-mail, but she assumed that ‘‘someone
    from the Cheshire police sent it to me.’’75
    C.H.-R. testified that she did not presently have a
    copy of the e-mail printed out or saved electronically.
    C.H.-R. ‘‘was afraid to keep the e-mail’’ because it was
    labeled ‘‘for your eyes only or FYI only,’’ and she was
    afraid to show it to anyone or tell anyone about it. She
    testified, however, that she had printed a copy of the
    e-mail and deleted the electronic file sometime in Febru-
    ary or March of 2008. C.H.-R. showed a copy of the
    printout to her husband, W.R., and to a North Carolina
    news reporter who had come to their home. She did
    not give the news reporter a copy of the e-mail and
    asked her not to report about it given its confidential
    nature. She also showed the printed copy to her parents,
    who were upset by it and wrote letters to the Cheshire
    police; the police claimed they had never received those
    letters. She testified that W.R. had shown the printed
    copy to an attorney friend, and that they subsequently
    lost—and perhaps accidentally discarded—that printed
    copy. No evidence of the e-mail appeared after a search
    of her computer hard drive. C.H.-R. acknowledged that
    the communication described in the e-mail did not
    appear in the communications logs admitted into evi-
    dence at trial and that recordings provided to her for
    review by defense counsel did not include that commu-
    nication.76
    W.R. also testified at the hearing. He testified that
    C.H.-R. had shown him the e-mail when he came home
    one afternoon in January, 2008. He could not tell from
    the e-mail or the printout the origin of the message; he
    did not think that it had been forwarded by W but,
    perhaps, had come from the spouse of a Cheshire police
    officer. He did not think that it had come from the town
    of Cheshire itself and did not know where the sender
    of the e-mail had obtained the information therein. W.R.
    testified that, at that time, his family was frequently
    receiving e-mails from people whom they had not met—
    nearly twenty to thirty times per day—offering support
    and prayers. He recalled that it was about the case, and
    ‘‘that the Pacifica was returning, and the garage door
    . . . was going up.’’ W.R. also observed that it had a list
    of numerous communications between police officers
    during the response. He showed a printout of the e-mail
    to an attorney friend and asked about ‘‘normal police
    protocol’’ in the home invasion/hostage situation. When
    he got home, he placed the printout on top of his com-
    puter to ‘‘save’’ or ‘‘keep it . . . .’’ The attorney did not
    keep a copy of the e-mail and did not ask for one. W.R.
    had never seen the police call log that was admitted
    into evidence at Hayes’ and the defendant’s trials. Dur-
    ing W.R.’s testimony, the trial court sustained the state’s
    objection to the question whether the log in the e-mail
    ‘‘appear[ed] to you to be a document that could have
    been created by a nonpolice or like a layperson who
    was not involved in the response . . . .’’ With no argu-
    ment by the defendant in response, the trial court ruled
    that the question ‘‘call[ed] for an opinion [and] that
    [there was] no foundation that he has some expertise
    in this.’’
    As we noted previously, Winters, the information
    technology manager for the Cheshire Police Depart-
    ment, worked at the direction of Vignola to capture,
    log, and summarize the police department’s radio and
    telephonic communications during the home invasion
    incident, from the initial 911 call until the defendant
    and Hayes were taken into custody. See footnote 66 of
    this opinion. In reviewing those communications in
    July, 2007, Winters denied hearing ‘‘in words or in sub-
    stance a communication by or among Cheshire police
    officers to the effect that someone [had] observed the
    Chrysler Pacifica entering the driveway at that resi-
    dence and the garage door being elevated . . . .’’ Had
    he heard such a communication, he would have moved
    it into the application and documented its existence in
    the log. Even if Winters had missed that communication
    during his manual review in 2007, it would have
    remained archived on the Cheshire police servers, as
    well as, presumably, the backup drives maintained at
    town hall. See footnote 66 of this opinion.
    After hearing argument, the trial court first deter-
    mined that it was the defendant’s burden to prove the
    existence of the call log by a preponderance of the
    evidence, rejecting his reliance on State v. Colon, 
    272 Conn. 106
    , 
    864 A.2d 666
     (2004), cert. denied, 
    546 U.S. 848
    , 
    126 S. Ct. 102
    , 
    163 L. Ed. 2d 116
     (2005), for the
    proposition that his burden was merely to establish a
    prima facie showing of the call log’s existence; the court
    deemed Colon to be limited to a showing of authenticity
    of an already existing document, whereas the inquiry
    in this case is whether the document existed at all.
    Observing that it was undisputed that the call log and
    communication had never been turned over to the
    defense, the trial court stated that ‘‘the only question
    is whether the call [log] existed in the first place,’’ and
    it concluded that it ‘‘cannot find on the basis of the
    evidence presented . . . that, by a preponderance of
    the evidence, such a call existed.’’ Although the trial
    court agreed that C.H.-R. had ‘‘no incentive to fabricate
    testimony to help’’ the defendant, it nevertheless
    deemed evidence of the call log’s existence unreliable
    given the lack of evidence as to the e-mail’s origin and
    the fact that C.H.-R. and W.R. were ‘‘getting all sorts of
    information from people they didn’t know.’’ The trial
    court acknowledged that § 10-3 (1) of the Connecticut
    Code of Evidence77 allows other evidence of the con-
    tents of a writing, if the original is lost or destroyed,
    to be established by secondary evidence, but ultimately
    determined that there simply was not a preponderance
    of ‘‘credible evidence’’ beyond ‘‘guesswork or specula-
    tion’’ to establish the existence of the call log or the
    e-mail in which it had been contained.
    Having reviewed the defendant’s various claims on
    this point, we first conclude that the trial court properly
    required the defendant to prove the existence of the
    e-mail and call log containing the communication
    described by C.H.-R. by a preponderance of the evi-
    dence. The existence of undisclosed evidence under
    Brady ‘‘is an issue of fact for the determination of the
    trial court. . . . Furthermore, the burden is on the
    defendant to prove the existence of undisclosed excul-
    patory evidence. . . . A finding of fact will not be dis-
    turbed unless it is clearly erroneous in view of the
    evidence and pleadings in the whole record . . . .
    [W]hen a question of fact is essential to the outcome
    of a particular legal determination that implicates a
    defendant’s constitutional rights, and the credibility of
    witnesses is not the primary issue, our customary defer-
    ence to the trial court’s factual findings is tempered by
    a scrupulous examination of the record to ascertain
    that the trial court’s factual findings are supported by
    substantial evidence.’’ (Citation omitted; internal quota-

    –38.
    Although the quantum of proof necessary to establish
    the existence of undisclosed evidence is a question of
    first impression in Connecticut, our research reveals
    federal and sister state authority that requires the defen-
    dant to prove by a preponderance of the evidence the
    existence of evidence that is claimed to be Brady mate-
    rial, which is an inquiry that most often arises in the
    context of undisclosed cooperation agreements
    between prosecutors and witnesses. See, e.g., United
    States v. Reese, 
    745 F.3d 1075
    , 1083 (10th Cir.), cert.
    denied,

    616 Pa. 164
    , 201, 
    47 A.3d 63
     (2012). The preponderance
    of the evidence standard is consistent with existing
    Connecticut case law governing factual proof of consti-
    tutional violations as a preliminary matter. See, e.g.,
    State v. Thompson, 
    supra,
     
    305 Conn. 428
     (applying pre-
    ponderance standard in determining whether defendant
    procured absence of potential witness for purpose of
    hearsay exception under § 8-6 (8) of the Connecticut
    Code of Evidence because that ‘‘standard . . . is con-
    sistent with the standard used by courts in making other
    preliminary determinations of fact involving a defen-
    dant’s constitutional rights, such as whether a confes-
    sion was voluntary’’).
    Application of the preponderance of the evidence
    standard is particularly apt in this case, in which the
    defendant sought to establish the existence of a lost or
    destroyed document or recording, the admissibility of
    which is governed by § 10-3 of the Connecticut Code of
    Evidence; authority applying similar rules of evidence
    generally requires such proof to be by at least a prepon-
    derance of the evidence.78 See, e.g., Bobcar Media, LLC
    v. Aardvark Event Logistics, Inc., 
    354 F. Supp. 3d 375
    ,
    382 (S.D.N.Y. 2018) (applying Federal Rules of Evidence
    to claimed loss of assignment of patents); Kleenit, Inc.

    policy); Coxwell v. Coxwell, 
    296 Ga. 311
    , 312–13, 
    765 S.E.2d 320
     (2014) (lost antenuptial agreement). But see
    Estate of Bossio v. Bossio, 
    237 W. Va. 130
    , 134–35, 
    785 S.E.2d 836
     (2016) (requiring clear and convincing evi-
    dence to prove existence and contents of lost docu-
    ment). Accordingly, we conclude that the trial court
    properly required the defendant to prove the existence
    of the call log and C.H.-R.’s lost or deleted e-mail by a
    preponderance of the evidence.
    We further conclude that the trial court did not com-
    mit clear error in finding that the defendant had not
    proven the existence of the call log described in C.H.-
    R.’s lost or deleted e-mail, or the e-mail itself, by a
    preponderance of the evidence. Although the trial court
    found C.H.-R. and W.R. to be credible, the fact that the
    e-mail had been deleted and the printout lost rendered
    it impossible to determine the provenance of the mes-
    sage or the call log contained therein. Neither C.H.-R.
    or W.R. knew who had sent the e-mail, and a search of
    Cheshire’s communications server and records did not
    reveal a corresponding communication. Accordingly,
    we conclude that the trial court correctly concluded
    that the defendant had not established the existence of
    the call log claimed to have been contained in C.H.-
    R.’s e-mail.
    Finally, we address the defendant’s claim that the
    trial court abused its discretion in sustaining the state’s
    objection under § 7-1 of the Connecticut Code of Evi-
    dence, governing lay opinion testimony, to a question
    posed to W.R., namely, whether the e-mail ‘‘appear[ed]
    to you to be a document that could have been created
    by a nonpolice or like a layperson who was not involved
    in the response . . . .’’ See, e.g., State v. Holley, 
    327 Conn. 576
    , 604–606, 
    175 A.3d 514
     (2018) (setting forth
    background principles and abuse of discretion standard
    of review applicable to lay opinion evidence). The trial
    court sustained the state’s objection to this question,
    concluding that it ‘‘call[ed] for an opinion that [there
    was] no foundation that he has some expertise in this.’’
    We conclude that any error on this point is harmless,
    given that this issue turned on the lack of proof that
    the e-mail and the call log contained therein existed,
    as opposed to the authenticity of those documents.
    C
    Whether Certain Communications Not Disclosed
    by the State Were Material for Purposes
    of a Brady Violation
    It is undisputed that the state failed to disclose six
    Cheshire police communications that form the basis of
    the defendant’s Brady claim with respect to the police
    response, and two communications that concern the
    demeanor of the defendant and Hayes following their
    arrests. Before turning to those communications, we
    review the well established principles governing the
    defendant’s claim under Brady v. Maryland, 
    supra,
     
    373 U.S. 83
    . ‘‘Due process principles [under the fourteenth
    amendment to the United States constitution] require
    the prosecution to disclose to the defense evidence that
    is favorable to the defendant and material to his guilt
    or punishment. . . . [Thus] [i]n order to obtain a new
    trial for improper suppression of evidence, the [defen-
    dant] must establish three essential components: (1)
    that the evidence was favorable to the accused; (2)
    that the evidence was suppressed by the state—either
    inadvertently or wilfully; and (3) that the evidence was
    material to the case, i.e., that the accused was preju-
    diced by the lack of disclosure.’’ (Citations omitted.)
    Marquez v. Commissioner of Correction, 
    330 Conn. 575
    , 592, 
    198 A.3d 562
     (2019).
    ‘‘In Brady, the court held that the suppression by the
    prosecution of evidence favorable to an accused upon
    request violates due process [when] the evidence is
    material either to guilt or to punishment, irrespective
    of the good faith or bad faith of the [prosecutor]. . . .
    The United States Supreme Court also has recognized
    that [t]he jury’s estimate of the truthfulness and reliabil-
    ity of a . . . witness may well be determinative of guilt
    or innocence, and it is upon such subtle factors as the
    possible interest of the witness in testifying falsely that
    a defendant’s life or liberty may depend. . . . Accord-
    ingly, the Brady rule applies not just to exculpatory
    evidence, but also to impeachment evidence . . .
    which, broadly defined, is evidence having the potential
    to alter the jury’s assessment of the credibility of a
    significant prosecution witness. . . .
    ‘‘Not every failure by the state to disclose favorable
    evidence rises to the level of a Brady violation. Indeed,
    a prosecutor’s failure to disclose favorable evidence
    will constitute a violation of Brady only if the evidence
    is found to be material. The Brady rule is based on
    the requirement of due process. Its purpose is not to
    displace the adversary system as the primary means by
    which truth is uncovered, but to ensure that a miscar-
    riage of justice does not occur. Thus, the prosecutor is
    not required to deliver his entire file to defense counsel,
    but only to disclose evidence favorable to the accused
    that, if suppressed, would deprive the defendant of a
    fair trial . . . .’’ (Citations omitted; footnote omitted;
    internal quotation marks omitted.) Adams v. Commis-
    sioner of Correction, 
    309 Conn. 359
    , 369–70, 
    71 A.3d 512
     (2013); see id., 370 (noting that ‘‘a classic Brady
    case . . . involv[es] the state’s inadvertent failure to
    disclose favorable evidence’’).
    In the present case, it is undisputed that the communi-
    cations were not disclosed and constituted impeach-
    ment evidence. The sole issue concerns whether they
    were material under Brady, which ‘‘presents a question
    of law subject to plenary review.’’ Marquez v. Commis-
    sioner of Correction, supra, 
    330 Conn. 593
    . ‘‘Evidence
    is material when there would be a reasonable probabil-
    ity of a different result if it were disclosed. . . . A rea-
    sonable probability exists if the evidence could
    reasonably . . . put the whole case in such a different
    light as to undermine confidence in the verdict. . . .
    Materiality does not require, however, a demonstration
    . . . that disclosure of the suppressed evidence would
    have resulted ultimately in the defendant’s acquittal.
    . . . Instead, the operative inquiry is whether, in the
    absence of the evidence, the defendant received a fair
    trial . . . resulting in a verdict worthy of confidence.’’

    ‘‘This calls for a careful review of that [evidence] and
    its probable effect on the jury, weighed against the
    strength of the state’s case and the extent to which
    [the defendant was] otherwise able to [discredit the
    evidence]. . . . [E]vidence that may first appear to be
    quite compelling when considered alone can lose its
    potency when weighed and measured with all the other
    evidence, both inculpatory and exculpatory. Implicit
    in the standard of materiality is the notion that the
    significance of any particular bit of evidence can . . .
    be determined [only] by comparison to the rest.’’ (Cita-

    ‘‘stringent’’ and ‘‘strict’’ standard of materiality applica-
    ble when ‘‘a prosecutor obtains a conviction with evi-
    dence that he or she knows or should know to be false’’
    (internal quotation marks omitted)). We now turn to
    the undisclosed communications.
    1
    Police Response Communications
    The first communication at issue is a call from Chesh-
    ire police Sergeant Chris Cote to Officer Robert Regan,
    at 9:25:15 a.m. on July 23, 2007, discussing whether and
    where to attempt to intercept the Pacifica en route to
    the P family residence in response to a 911 call from
    the Bank of America.79 The defendant argues that this
    first call supports the proposition that Cote was in a
    position to locate and to stop the Pacifica, yet failed
    to do so. The defendant argues that the other five calls
    suggest a failure by the Cheshire police to marshal
    necessary resources in a timely manner. Specifically,
    the second call is an internal communication at 9:27:52
    a.m. between Vignola and Cheshire Police Captain Ren
    Marchand, who was the shift commander, indicating
    that Vignola was ‘‘heading out’’ to the scene.80 The third
    communication is one between 9:36:18 and 9:36:45 a.m.,
    in which Vignola advises that he will ‘‘drive by’’ the P
    family house and receives a description of it from Offi-
    cer Phillip Giampietro.81 The fourth communication is
    one in which the caller, who is a hostage negotiator, is
    directed not to report to the station.82 The fifth commu-
    nication is one in which Cheshire special response team
    members are directed not to report to the station.83 The
    sixth call is one in which an unidentified Cheshire police
    officer appears to have briefly questioned the account
    of the incident that J provided at Bank of America,
    which had been relayed to the police.84
    The defendant argues that these undisclosed commu-
    nications would have provided further impeachment
    evidence with respect to the veracity of the Cheshire
    police witnesses by providing support for the theory
    that their testimony was colored by their remorse for
    an inadequate police response. As the defendant
    acknowledges in his brief, however, the principal issues
    of fact at the guilt phase of the trial were whether he
    had (1) committed an anal sexual assault of M, and (2)
    intended to kill J, H, and M. A review of the record,
    including the parties’ closing arguments and the sup-
    porting evidence, confirms that none of the undisclosed
    material impeaches the veracity of the Cheshire police
    witnesses in a manner that undermines our confidence
    in the verdict as to the disputed fact issues. With respect
    to the sexual assault of M, the recovery of the defen-
    dant’s DNA from her anus provides ample and over-
    whelming support for the jury’s verdict on that count,
    with any inadequacy in the police response to the emer-
    gency bearing no relation to his theory, proffered during
    closing argument, that the rectal swab taken from M
    must have been cross-contaminated with the defen-
    dant’s DNA by a technician in the Connecticut Forensic
    Science Laboratory (state lab), insofar as there was no
    other evidence of sexual assault such as physical injury
    to M’s anal area or the presence of M’s DNA on the
    defendant’s penis.85
    The state sought to prove the defendant’s intent to
    kill by circumstantial evidence given the defendant’s
    denials of such intent in his statement. The state relied
    on the defendant’s motive of hiding the evidence of his
    sexual assault of M and his failure to walk out of the
    house and abort the crimes during the opportunities
    presented when Hayes was out of the house buying
    gasoline and taking J to the bank, along with his act
    of retying H and M to their beds after they had been
    permitted to use the bathroom and M had showered.
    The state also argued that the defendant had poured
    bleach on M’s shorts in an attempt to eliminate DNA
    evidence. The state further relied on evidence that gaso-
    line had been poured only in areas of the P home where
    people were present. The state also emphasized that
    gasoline was found on the defendant’s clothes and
    debunked his explanation that the gasoline was the
    result of his work activities by using Stop and Shop
    surveillance video showing him wearing different
    clothes when he stalked J and M at the store after work
    than when he was arrested after perpetrating these
    crimes. None of the undisclosed evidence pertaining to
    the police response affected this evidence of intent in
    any way, as it did not depend on the observations or
    veracity of the Cheshire police witnesses. Accordingly,
    we conclude that the additional evidence that would
    raise the question of an inadequate police response was
    not material to the guilt issues at this trial, and the state’s
    failure to disclose it did not, therefore, violate Brady.
    2
    Communications About the Defendant’s
    Appearance and Demeanor
    The defendant next claims that two communications
    describing his demeanor and Hayes’ appearance were
    material for Brady purposes. The first communication
    is one in which Shawn Patterson, a Cheshire police
    officer, described the defendant to another officer as
    ‘‘nobody home’’ and ‘‘simple as they come.’’86 The defen-
    dant argues that this communication was material to
    the voluntariness of his statements, which was an issue
    that he addressed in closing argument, and the waiver
    of his Miranda rights, and that the trial court would
    have granted his pretrial motion to suppress his state-
    ment on the ground that it was not voluntary because
    of sleep deprivation and injury from the collision
    between the Pacifica and the Cheshire police cruisers.
    In response, the state contends that Patterson’s state-
    ment was not material because any information that
    could be drawn from it was amply duplicated firsthand
    at trial, including by Vitello’s description of the defen-
    dant during the interview and the audio recording of
    the defendant’s statement. We agree with the state and
    conclude that Patterson’s description of the defendant
    was not material.
    A review of the record satisfies us that Patterson’s
    description of the defendant was not material for Brady
    purposes because its omission does not undermine our
    confidence in the fairness of the trial or the suppression
    hearing in this case. It is not reasonably likely that
    Patterson’s testimony would have changed the fact find-
    er’s determination on this point, given the uncontro-
    verted evidence at the Floyd hearing that Patterson’s
    contact with the defendant was at most a fleeting obser-
    vation in the hallway of the police station; he took no
    part in the response to the P home or the ensuing
    investigation and was not present for the interview.87
    Indeed, Patterson’s testimony was at best cumulative
    of more probative evidence as to the defendant’s
    demeanor, namely, Vitello’s testimony that the defen-
    dant was emotionless during the period of time follow-
    ing his arrest, and the lengthy recording of the
    defendant’s statement, which the trial court and the
    jury had the opportunity to hear for themselves. See,
    e.g., State v. Wilcox, 
    254 Conn. 441
    , 458, 
    758 A.2d 824
    (2000); Morant v. Commissioner of Correction, 
    117 Conn. App. 279
    , 298–99, 
    979 A.2d 507
    , cert. denied, 
    294 Conn. 906
    , 
    982 A.2d 1080
     (2009).
    We now turn to the second communication, which
    is a discussion between Cheshire Police Detective Kerry
    Nastri and Connecticut State Trooper David Devito,
    in which one of the two officers88 describes Hayes as
    ‘‘look[ing] evil.’’89 The defendant argues that this state-
    ment would have supported his argument that Hayes
    was the mastermind in charge of the events at the house
    and that the defendant wanted no part of killing the P
    family, especially when considered in light of evidence
    of the defendant’s apparent slow reaction to the
    unfolding events, such as Patterson’s statement. The
    state argues that this statement was not material
    because it was ‘‘gossip’’ that did not necessarily reflect
    what Hayes or the defendant looked like at the time of
    the home invasion. We agree with the state and con-
    clude that this casual observation of Hayes’ appearance
    as ‘‘evil’’ was not material. In the absence of any evi-
    dence that the officers heard Hayes make any state-
    ments that would support the defendant’s theory, an
    offhand impression of Hayes as ‘‘look[ing] evil’’—with
    no further elaboration—does nothing to inform the
    jury’s assessment of what actually happened in the P
    residence, whether considered in isolation or cumula-
    tively. Accordingly, we conclude that this undisclosed
    evidence was not material for purposes of Brady.
    IV
    NAPUE AND GIGLIO CLAIMS ARISING FROM
    PHOTOGRAPH ON DEFENDANT’S
    CELL PHONE
    The defendant next claims that the state deprived
    him of his right to a fair trial under Giglio v. United
    States, supra, 
    405 U.S. 150
    , and Napue v. Illinois, 
    supra,
    360 U.S. 264
    , among other cases, by presenting evidence
    that it knew or should have known was false or highly
    misleading, namely, an inflammatory photograph taken
    from the defendant’s cell phone that the state’s expert
    witness, John Brunetti, testified was of M in a sexually
    explicit pose. In contrast to Brunetti’s testimony at the
    defendant’s trial, John Farnham, an analyst at the state
    lab, who also testified at the defendant’s trial, testified
    as an expert witness at Hayes’ trial that the same photo-
    graph was of a different female, and not M, who was
    prepubescent. The defendant contends that Brunetti’s
    testimony was, therefore, misleading evidence that vio-
    lated his right to a fair trial because the state capitalized
    on it during closing argument, insofar as it was ‘‘expo-
    nentially more inflammatory by the state’s claim that
    it depicted an eleven year old child,’’ and it undermined
    portions of his statement stating that he did not anally
    rape M, believed that she was between fourteen and
    sixteen years old, and did not intend anyone to be killed
    or pour gasoline at the scene. In response, the state
    contends, inter alia, that ‘‘there is no reasonable possi-
    bility that any falsity affected the outcome of the trial.’’
    We agree with the state and conclude that there is no
    reasonable likelihood that any falsity or substantially
    misleading testimony by Brunetti on this point affected
    the outcome of the defendant’s trial.
    The record reveals the following additional relevant
    facts and procedural history. At the defendant’s trial,
    H. Wayne Carver II, then the state’s chief medical exam-
    iner, testified about his autopsy of M. He described her
    as ‘‘a young adolescent female,’’ stating that she was
    eleven years old ‘‘and the body looked like it, and, at
    the time of the autopsy, she weighed 124 pounds.’’
    (Emphasis added.) In describing the various samples
    that he took from M’s body, Carver stated that he had
    taken ‘‘a sample of hairs, and I don’t think she had
    much more than head hair, but, if she had other hairs,
    we would have taken them and labeled them.’’ (Empha-
    sis added.) Carver further stated that he performed
    various ‘‘swabs and smears’’ to retrieve material from
    M’s oral, vaginal, and anal areas.
    Farnham, a retired state police detective who worked
    in the computer crime unit at the state lab, had exam-
    ined, pursuant to a search warrant, cell phones belong-
    ing to the defendant and Hayes; he retrieved text
    messages from both phones and photographs from the
    defendant’s phone. Farnham retrieved eight photo-
    graphs within the date and time period specified by
    the search warrant; he testified that two depicted the
    defendant and six ‘‘showed a young white female on a
    bed . . . .’’ The six images were admitted into evidence
    as state’s exhibit 209.90
    Brunetti, who worked in the multimedia and image
    enhancement section of the state lab, had reviewed the
    six images in state’s exhibit 209, which were taken
    between 7:27 and 9:14 a.m. on July 23, 2007. The first
    five images depict a partially clothed young female,
    whose head is covered; two of those images are a close-
    up photograph of the female’s genital area, which is
    covered by underwear. The sixth image in state’s exhibit
    209 depicts an unclothed female lying on her back, with
    her legs raised at close to a ninety degree angle; the
    female’s genitalia and anus are covered by a black bar
    that Brunetti had added to the original photograph for
    ‘‘[d]iscretion.’’ Brunetti opined that all six of the images
    were of the same person, namely, M.91 The defendant
    cross-examined Brunetti briefly but did not question
    him about his conclusion that the six images all
    depicted M.
    In contrast to Brunetti’s testimony at the defendant’s
    trial, the record, as augmented on appeal after the Floyd
    hearing,92 reveals that Farnham testified at Hayes’ trial
    that the sixth image was of ‘‘a different female, appar-
    ently older than the first female picture that was taken,’’
    and that, ‘‘[b]ased on the size of the person, it doesn’t
    appear to be the same person; this person has reached
    puberty.’’ (Emphasis added.) As the defendant observes
    in his brief, the sixth image that was admitted into
    evidence at Hayes’ trial is unredacted and ‘‘shows that
    the female has reached puberty and has more than head
    hair,’’ which is inconsistent with Carver’s description
    of M.
    ‘‘Whether a prosecutor knowingly presented false or
    misleading testimony [in violation of a defendant’s due
    process rights] presents a mixed question of law and
    fact, with the [trial] court’s factual findings subject to
    review for clear error and the legal conclusions that
    the court drew from those facts subject to de novo
    review. . . .
    ‘‘[D]ue process is . . . offended if the state, although
    not soliciting false evidence, allows it to go uncorrected
    when it appears. . . . Regardless of the lack of intent
    to lie on the part of the witness, Giglio and Napue
    require the prosecutor to apprise the court when he or
    she knows that the witness is giving testimony that is
    substantially misleading. . . .
    ‘‘To establish a Napue/Giglio violation, then, the
    [defendant] must demonstrate that the state’s witnesses
    provided material, false or substantially misleading tes-
    timony that the prosecutor failed to correct.’’ (Citations

    (Napue and Giglio ‘‘do not apply to merely ‘misleading’
    testimony in the first instance. Rather, those cases
    require the prosecutor to correct only testimony that
    is substantially misleading or false.’’ (Emphasis in
    original.)).
    Whether the prosecutor’s presentation of false or sub-
    stantially misleading testimony constitutes a due pro-
    cess violation depends on whether the evidence at issue
    is material. In contrast to conventional Brady claims,
    ‘‘[w]hen . . . a prosecutor obtains a conviction with
    evidence that he or she knows or should know to be
    false, the materiality standard is significantly more
    favorable to the defendant. [A] conviction obtained by
    the knowing use of perjured testimony is fundamentally
    unfair, and must be set aside if there is any reasonable
    likelihood that the false testimony could have affected
    the judgment of the jury. . . . This standard . . .
    applies whether the state solicited the false testimony
    or allowed it to go uncorrected . . . and is not substan-
    tively different from the test that permits the state to
    avoid having a conviction set aside, notwithstanding a
    violation of constitutional magnitude, upon a showing
    that the violation was harmless beyond a reasonable
    doubt. . . . This strict standard of materiality is appro-
    priate in such cases not just because they involve prose-
    cutorial [impropriety], but more importantly because
    they involve a corruption of the truth-seeking function
    of the trial process. . . . In light of this corrupting
    effect, and because the state’s use of false testimony
    is fundamentally unfair, prejudice sufficient to satisfy
    the materiality standard is readily shown . . . such
    that reversal is virtually automatic . . . unless the
    state’s case is so overwhelming that there is no reason-
    able likelihood that the false testimony could have
    affected the judgment of the jury. . . .
    ‘‘In accordance with these principles, our determina-
    tion of whether [the witness’] false testimony was mate-
    rial under Brady and its progeny requires a careful
    review of that testimony and its probable effect on the
    jury, weighed against the strength of the state’s case
    and the extent to which [the defendant was] otherwise
    able to impeach [the witness].’’ (Emphasis in original;

    .
    Assuming without deciding that Brunetti’s testimony
    at the defendant’s trial that the sixth image in state’s
    exhibit 209 depicted M was false or substantially mis-
    leading, we conclude that it was not material and did
    not violate the defendant’s due process rights under
    Napue and Giglio.93 Specifically, our review of the
    record demonstrates that there is no reasonable likeli-
    hood that Brunetti’s testimony identifying the sixth pho-
    tograph as M would have affected the jury’s verdict,
    despite its inconsistency with Farnham’s testimony on
    this point at Hayes’ trial. First, there is no dispute that
    the other five images in state’s exhibit 209 were of M,
    which corroborates the defendant’s statement to the
    police that he took photographs of M for his ‘‘personal
    use.’’ Second, the content of the image does not bear
    on any of the contested issues in the guilt phase, and
    particularly whether the sexual assault that the defen-
    dant had committed was by anal intercourse rather than
    the claimed cunnilingus, or whether he had the requisite
    intent to kill.94 Third, if the person in the image at issue
    was not M, based on the timing of the photograph,
    it had to have been H, which would have added the
    differently inflammatory specter of an additional sexual
    assault victim to the case. Indeed, the entirely tangential
    nature of this issue is borne out by the defendant’s
    failure to cross-examine Brunetti on this point, despite
    having had access to Farnham’s testimony at Hayes’
    trial and indications in the photographs—namely, dif-
    ferent bedding as a backdrop—that suggest that the
    images were of different people. Accordingly, we con-
    clude that any misleading testimony on this point was
    not material under Napue and Giglio, and did not
    deprive the defendant of a fair trial.
    V
    CONDITIONS OF CONFINEMENT
    Finally, the defendant claims that the trial court
    unconstitutionally applied the stringent conditions of
    confinement set forth in § 18-10b after his death sen-
    tence was vacated and he was resentenced to life
    imprisonment without the possibility of release and
    subsequently transferred to a prison in Pennsylvania.
    Specifically, the defendant contends that the restrictive
    conditions of confinement set forth in § 18-10b, as
    implemented by an administrative directive of the
    department, constitute an ex post facto law, violate
    equal protection, and are excessive and disproportion-
    ate, in violation of the eighth amendment to the United
    States constitution and article first, §§ 8 and 9, of the
    Connecticut constitution. In response, the state relies
    on State v. Campbell, supra, 
    328 Conn. 444
    , and argues
    that this claim is not ripe for review because the record
    lacks evidence or factual findings regarding the defen-
    dant’s conditions of confinement or the procedures uti-
    lized by the department in determining those
    conditions. We agree with the state and conclude that
    this conditions claim, although ripe, is not reviewable
    in this direct appeal.
    In Campbell, the defendant, Jessie Campbell III,
    argued that his penalty phase claims were not moot,
    despite the abolition of the death penalty, because he
    would suffer collateral consequences as a result of the
    previously imposed death sentence, namely, the imposi-
    tion of restrictive conditions of confinement pursuant
    to § 18-10b. See State v. Campbell, supra, 
    328 Conn. 461
    .
    We agreed with the state’s argument that Campbell’s
    conditions of confinement claim was not yet ripe for
    review95 because those conditions ‘‘have not yet been
    settled, as [Campbell] ha[d] not yet been resentenced.
    Additionally, there ha[d] been no factual findings as to
    how, if at all, [Campbell’s] confinement, after resentenc-
    ing, would differ from those of any inmate who is simi-
    larly situated.’’ 
    Id.,
     462–63. We further concluded that,
    ‘‘because [Campbell’s] argument centers on a potential
    challenge to conditions of confinement, the proper vehi-
    cle for those claims is a petition for a writ of habeas
    corpus.’’ Id., 463. Accordingly, we dismissed the appeal
    in Campbell ‘‘with respect to his claims challenging the
    penalty phase and the sentence of death.’’ Id., 466; see
    id., 463 n.5 (deeming penalty phase claims challenging
    death sentence moot).
    Although the defendant in this case has been resen-
    tenced, in contrast to Campbell, whose resentencing
    was still hypothetical, rendering a challenge thereto not
    ripe; see id., 464; that is a distinction without a differ-
    ence with respect to the reviewability of the merits of
    the defendant’s claim in this appeal. With respect to
    the equal protection challenge in particular, which
    focuses on the claimed disparate treatment of defen-
    dants who had received life sentences after the abolition
    of the death penalty as compared to capital defendants
    who had previously received life sentences, there is no
    evidence in the record beyond an averment of informa-
    tion and belief in the defendant’s brief as to the treat-
    ment of similarly situated inmates. Additionally, there is
    no evidence as to the conditions of confinement actually
    imposed on the defendant, who is presently incarcer-
    ated in Pennsylvania. Any merit with respect to the
    defendant’s § 18-10b claims aside, they implicate his
    conditions of confinement. ‘‘It is well established that
    the proper vehicle by which a defendant may challenge
    his conditions of confinement is a petition for a writ
    of habeas corpus. . . . The present case illustrates per-
    fectly why a habeas petition is the proper vehicle. In the
    habeas court, the defendant will have the opportunity
    to present any and all evidence that is relevant to his
    claim. That court is empowered to make factual findings
    on that evidence. This court is not.’’ (Citation omitted.)
    Id., 465–66. Accordingly, we leave the merits of the
    defendant’s conditions of confinement claim under
    § 18-10b to a subsequent habeas corpus proceeding.96
    The judgment is affirmed.
    In this opinion the other justices concurred.
    * This case originally was scheduled to be argued before a panel of this
    court consisting of Chief Justice Robinson, Justices Palmer, D’Auria, Mullins,
    Ecker, and Judges Alvord and Keller. Although Justice Mullins was not

    The defendant appealed directly to this court pursuant to General Stat-
    utes § 51-199 (b) (4).
    2
    General Statutes § 18-10b provides in relevant part: ‘‘(a) The Commis-
    sioner of Correction shall place an inmate on special circumstances high
    security status and house the inmate in administrative segregation until a
    reclassification process is completed under subsection (b) of this section,
    if . . . (2) the inmate is in the custody of the Commissioner of Correction
    for a capital felony committed prior to April 25, 2012, under the provisions
    of section 53a-54b in effect prior to April 25, 2012, for which a sentence of
    death is imposed in accordance with section 53a-46a and such inmate’s
    sentence is (A) reduced to a sentence of life imprisonment without the
    possibility of release by a court of competent jurisdiction, or (B) commuted
    to a sentence of life imprisonment without the possibility of release.
    ‘‘(b) The commissioner shall establish a reclassification process for the
    purposes of this section. The reclassification process shall include an assess-
    ment of the risk an inmate described in subsection (a) of this section poses
    to staff and other inmates, and an assessment of whether such risk requires
    the inmate’s placement in administrative segregation or protective custody.
    If the commissioner places such inmate in administrative segregation pursu-
    ant to such assessment, the commissioner shall require the inmate to com-
    plete the administrative segregation program operated by the commissioner.
    ‘‘(c) (1) The commissioner shall place such inmate in a housing unit for
    the maximum security population if, after completion of such reclassification
    process, the commissioner determines such placement is appropriate, pro-
    vided the commissioner (A) maintains the inmate on special circumstances
    high security status, (B) houses the inmate separate from inmates who are
    not on special circumstances high security status, and (C) imposes condi-
    tions of confinement on such inmate which shall include, but not be limited
    to, conditions that require (i) that the inmate’s movements be escorted or
    monitored, (ii) movement of the inmate to a new cell at least every ninety
    days, (iii) at least two searches of the inmate’s cell each week, (iv) that no
    contact be permitted during the inmate’s social visits, (v) that the inmate
    be assigned to work assignments that are within the assigned housing unit,
    and (vi) that the inmate be allowed no more than two hours of recreational
    activity per day.
    ‘‘(2) The commissioner shall conduct an annual review of such inmate’s
    conditions of confinement within such housing unit and the commissioner
    may, for compelling correctional management or safety reasons, modify any
    condition of confinement, subject to the requirements of subparagraphs (A)
    to (C), inclusive, of subdivision (1) of this subsection. . . .’’

    Whether the defendant had sexually assaulted M anally was a disputed
    issue during the guilt phase of the trial. In his statement, the defendant
    admitted to sexually assaulting M by performing oral intercourse on her,
    stating that he believed she was between the ages of fourteen and sixteen
    years old. He denied performing other sexual acts with M. The jury, however,
    reasonably could have concluded that the defendant had anal intercourse
    with M on the basis of the testimony of H. Wayne Carver II, then the state’s
    chief medical examiner, that semen containing the defendant’s DNA was
    found in M’s anus during her autopsy, with the lack of visible injuries to
    that area not inconsistent with penetration having occurred. The state’s
    DNA testing eliminated Hayes, along with W, J, and H, as potential sources
    of the DNA found in M.
    4
    The Cheshire Police Department initiated a radio broadcast alerting all
    units about the ongoing hostage situation at 9:26 a.m. Captain Robert Vignola,
    who was the incident commander, testified that responding police units
    acted to create a perimeter and surround the house, and to close the sur-
    rounding roadways; they had been ordered not to approach the house by
    Captain Ren Marchand, who was at the police station and had relied on
    information that J had relayed to Lyons that the defendant and Hayes had
    not mistreated them to that point but would kill them if the police were called.
    5
    Testimony from H. Wayne Carver II, then the state’s chief medical exam-
    iner, and Malka Shah, an assistant medical examiner, established that H
    and M, who also sustained severe burns, were killed by asphyxiation from
    inhaling smoke containing toxic carbon monoxide.
    6
    The officers spoke to the defendant after Hayes did not answer any of
    their questions, stating only that ‘‘things just got out of control.’’
    7
    The defendant moved to suppress this statement and an additional state-
    ment that he had made concerning two break-ins in the neighborhood that
    the state wished to offer as uncharged misconduct evidence. The defendant
    argued that he had not made a voluntary, knowing, and intelligent waiver
    of his privilege against self-incrimination pursuant to Miranda v. Arizona,
    
    384 U.S. 436
    , 86 S. Ct.1602, 
    16 L. Ed. 2d 694
     (1966), because he had made
    those statements while sleep deprived and under the influence of injuries
    sustained in the vehicle crash while fleeing. Following an evidentiary hearing
    on August 23, 2011, the trial court denied the motion to suppress, concluding
    that the defendant’s arguments were speculative and unsupported by the
    evidence. The defendant does not directly challenge the trial court’s ruling
    on the motion to suppress in this appeal, although it is implicated by one
    of his Brady claims. See part III C 2 of this opinion.
    8
    In resentencing the defendant, for double jeopardy purposes, the trial
    court vacated three of the defendant’s murder sentences and his sexual
    assault sentence pursuant to this court’s decision in State v. Polanco, 
    308 Conn. 242
    , 245, 
    61 A.3d 1084
     (2013).
    9
    We note that the defendant suggests, but does not address in detail,
    additional claims of error arising from the pretrial publicity and jury selec-
    tion, which we decline to review. See footnote 27 of this opinion.
    10
    Penrod, who holds the position of distinguished professor, has focused
    his experimental research on jury decision making, including the effect on
    juries of exposure to pretrial publicity. He has administered surveys to
    assess the effects of pretrial publicity in approximately twenty-five civil and
    criminal cases over a twenty-five year period in connection with providing
    expert testimony on pretrial publicity and venue matters.
    11
    Kovera consulted with Penrod in developing the study. She has con-
    ducted numerous studies on jury decision making and the effects of pretrial
    publicity, and has published two books and more than fifty scientific journal
    articles and book chapters. Like Penrod, she also has testified as an expert
    witness in numerous venues, including Iowa, New York, Maryland, and
    Canada.
    12
    At the hearing on the motion to change venue, Penrod testified that the
    defendant’s attorneys had selected the four judicial districts. Penrod was
    familiar with them because he had also performed a similar study in connec-
    tion with Hayes’ trial.
    13
    Penrod stated that his researchers did not ask questions about case
    knowledge until after they had preliminarily established that the juror would
    be qualified to serve on a jury in Connecticut by verifying their age, United
    States citizenship, residence in the district being studied, and their qualifica-
    tion to serve on a death penalty jury under United States Supreme Court
    case law. The study excluded without further inquiry those survey respon-
    dents who reported knowing any person involved in the case, including
    attorneys and witnesses.
    14
    The defendant suggested the judicial district of Fairfield as an alternative
    to Stamford.
    15
    In addition to Penrod, Celia Lofink, a psychologist who had assisted
    the defendant’s legal team by tracking media coverage of this case, testified
    at the hearing. Lofink testified that her research, conducted by capturing
    Google Alerts to news articles using the defendant’s last name and W’s name
    indicated that there were 1808 media reports about this case from the date
    of the offense through the date of the hearing. Lofink’s results reflected
    worldwide coverage, although the majority of the articles were from Con-
    necticut. Lofink then presented the court with a chronologically organized
    table identifying each article by title and source, along with a flash drive
    containing the text and any reader comments accompanying those articles,
    both of which were admitted into evidence as court exhibits. Lofink testified,
    however, that she was not aware of any technology that would allow her
    to determine how many people had actually read each article.

    The case of Lyle and Erik Menendez, two young men who killed their
    wealthy parents in Beverly Hills, California, in 1989, involved a nationally
    televised trial at which they claimed self-defense from physical and sexual
    abuse. They were tried jointly, with a separate jury for each brother; the juries
    hung at the first trial, but the brothers were convicted at their second trial
    before a single jury. See Biography.com Editors, Erik Menendez Biography

    John Walker Lindh is an American citizen who was captured in Afghani-
    stan in 2001, where he had lent aid to Osama Bin Laden’s terrorist organiza-
    tion, Al Qaeda, and participated in a prison uprising that led to the death
    of a Central Intelligence Agency officer. See, e.g., C. Rosenberg, ‘‘ ‘American
    Taliban,’ Held 17 Years, Nears Release,’’ N.Y. Times, May 22, 2019, p. A1.
    18
    Once a survey respondent established some knowledge of the case, the
    survey progressed to open-ended questions to assess additional knowledge
    of the incident, followed by specific inquiries about whether the respondent
    (1) had read a book written about the case, (2) had seen a television interview
    of W by Oprah Winfrey, (3) had heard about journals the defendant had
    written in prison, (4) had learned of the Hayes trial and verdict, (5) had
    followed the media coverage of this case, (6) could be fair and impartial
    and render a verdict based only on the evidence presented at trial in this
    case, and (7) believed that the defendant should be executed.
    With respect to more granular knowledge of the case, the most prominent
    answer among the 1284 people across the four judicial districts who recog-
    nized the case was that 60 percent provided some information about the
    victims, with 42 percent being aware that the victims were the wife and
    daughters, and 25 percent, the next largest category, being aware that the
    husband escaped. Fifty-five percent had some information about the perpe-
    trators, with more than half remembering that there were multiple perpetra-
    tors, 9 percent being aware of their status as parolees, and 10 percent being
    aware of Hayes’ conviction. With respect to the crime itself, 58 percent were
    aware of some detail, with 30 percent being aware of the sexual assaults,
    robbery, or fire. Thirty-three percent categorized the crime as ‘‘horrible’’
    or ‘‘heinous.’’
    Turning to death qualification, Penrod stated that, across the four judicial
    districts, approximately two-thirds of those persons surveyed would not
    automatically vote for the death penalty, and approximately 75 percent
    would not allow their personal views on the death penalty to preclude them
    from rendering a guilty verdict.
    19
    In New Haven, more respondents could offer greater detail about the
    case, with most able to offer an average of five or six details rather than
    the two or three provided by respondents in the other districts.
    20
    Conversely, in New Haven, 2.5 percent of the population reported a
    ‘‘positive’’ impression of the defendant, as compared to 1.6 percent in Stam-
    ford. In New Haven, 27 percent of the respondents could not suggest the
    most compelling evidence against the defendant, as compared to 48 percent
    in Stamford.
    21
    Fifteen percent of the respondents in Stamford did not know how to
    answer the question regarding their certainty as to the defendant’s guilt, as
    compared to 6 percent in New Haven.
    22
    Penrod stated in response to questions from the trial court that the
    margin of error was 5 or 6 percent depending on various underlying factors
    in the study. With that margin of error factored in, Penrod still believed
    that it was a significant enough difference to move the trial from New Haven
    to Stamford, particularly given the lower volume of coverage in the Stamford
    Advocate as compared to the New Haven Register.
    23
    Penrod explained that the intersection of those who believed that they
    could be fair and impartial, yet who had also prejudged the defendant’s
    guilt, raised concerns of ‘‘conformity prejudice,’’ in which jurors ‘‘worry
    about how they will be perceived in the broader community if they come
    back with a verdict that’s at odds with community expectations about
    things.’’ Penrod described conformity prejudice as a concept that is rooted
    in social norms about jury service as a civic responsibility, and as indicating
    that pretrial publicity has an ‘‘endur[ing]’’ effect that lasts through the presen-
    tation of trial evidence and into deliberations. The concept of conformity
    prejudice extends from guilt to the death penalty determination. Penrod
    believed that conformity prejudice was a ‘‘reasonable concern’’ in this case
    because there was ‘‘so much knowledge about the case’’ and a ‘‘clear senti-
    ment toward guilt,’’ with ‘‘part of that knowledge . . . about the nature of
    the case and the perception of it being a gruesome case.’’ He explained that
    the concept of conformity prejudice drove the decision to move Timothy
    McVeigh’s federal trial for the Oklahoma City bombing from Oklahoma City
    to Denver, given the concern that it would be difficult for jurors to return
    to the community having not returned its desired verdict—a concern that
    Penrod believed extended to this case.
    With respect to conformity prejudice, Penrod noted that studies have
    shown a differing response rate to the question about whether the respon-
    dent can be fair and impartial, where people are significantly—nearly 60
    percent—more likely to admit difficulties remaining impartial during a sur-
    vey than they would in response to a question from a judge during jury
    selection. Penrod also testified that studies indicate that people have diffi-
    culty recognizing their own biases, including those arising from the effects
    of pretrial publicity, and are attuned to give ‘‘socially desirable response[s]’’
    to questions on this topic. Penrod observed that the very effect of the juror
    oath administered by an authority figure, namely, the trial judge—even
    during voir dire—might be to reinforce, rather than to alleviate, the effect
    of conformity prejudice.
    24
    We discuss the voir dire of individual jurors in detail in part I D of
    this opinion.
    25
    The trial court had denied the defendant’s request for a total of sixty
    peremptory challenges, which would be twice the number statutorily granted
    to the state.
    26
    The defendant argued that the additional challenges were necessary to
    preserve his right to an impartial jury in light of pretrial publicity that
    resulted in both overt and conformity prejudice. For a discussion of confor-
    mity prejudice, see footnote 23 of this opinion.
    27
    The defendant also appears to raise, as independent claims of error,
    arguments that the trial court improperly (1) declined to discontinue jury
    selection after Senator Prague made her lynching comments, (2) denied his
    motions to dismiss various panels of prospective jurors based on certain
    outbursts in court by prospective jurors, (3) declined to award him additional
    peremptory challenges, (4) denied his motions to sequester the jury, (5)
    denied his request to use a jury questionnaire, (6) denied his motion to
    preclude supporters of the P family from wearing pins from the P Family
    Foundation in the courtroom, (7) denied his motion to remove newspaper
    boxes located outside the courtroom, (8) failed sua sponte to require that
    jurors inform the court of exposure to publicity or communications about
    the case, or to staunch the flood of comments by the state or to permit the
    defendant relief from the gag order to respond publicly, and (9) failed
    sua sponte to instruct the venirepersons not to discuss the case among
    themselves. To the extent that these nine arguments constitute independent
    claims of error outside the purview of the constitutional claims regarding
    actual or presumed prejudice, we decline to reach them because we agree
    with the state’s argument that they are inadequately briefed, with virtually
    no independent legal analysis. See, e.g., Lafferty v. Jones, 
    336 Conn. 332
    ,
    375 n.30, 
    246 A.3d 429

    138 A.3d 868
    (2016). We do, however, consider their factual predicates within the context
    of the actual and presumptive prejudice claims, which we address in
    great detail.

    with which [the] petitioner was charged and each had some knowledge of
    [the] petitioner’s past crimes, but none betrayed any belief in the relevance
    of [the] petitioner’s past to the present case. Indeed, four of the six jurors
    volunteered their views of its irrelevance, and one suggested that people
    who have been in trouble before are too often singled out for suspicion of
    each new crime—a predisposition that could . . . operate [only] in [the]

    criminal history, details of his confession to murder and robbery spree, and
    his offer to plead guilty to avoid death penalty in newspaper that was
    circulated to 95 percent of small, rural community of only 30,000 people,
    with 8 of 12 seated jurors believing he was guilty, despite assurances of
    impartiality).
    29
    This principle has, of course, also been applied in notorious cases in
    larger metropolitan areas. See United States v. Warren, 
    989 F. Supp. 2d 494
    ,
    499–500, 502–504 (E.D. La. 2013) (denying motion to transfer venue for
    New Orleans police officers’ retrial in Danziger Bridge shooting case after
    Hurricane Katrina because district had population of 1.5 million, nearly
    three years had passed since first trial, and court would utilize questionnaires
    and individual voir dire to identify potential jury prejudice); United States
    v. Mitchell, 
    752 F. Supp. 2d 1216
    , 1220–27 (D. Utah 2010) (no presumed

    when jury was selected after extensive voir dire, which included individual
    questioning as to effect of pretrial publicity, from county that included city
    of Cleveland with population of more than 1.2 million).
    We acknowledge, however, that even a relatively large population may
    not necessarily obviate the need to move a trial in a particularly notorious
    case. See United States v. Casellas-Toro, 
    807 F.3d 380
    , 386–88 (1st Cir. 2015)
    (size of District of Puerto Rico, with 3 million residents, was balanced by

    City given overwhelming and sensational pretrial publicity—including adver-
    tisements taken out by American Civil Liberties Union against defendants,
    commentary by public officials and opinion writers, and mass demonstra-
    tions—on point that ‘‘the two undisputed facts, namely that [forty-one] shots
    were fired and that . . . Diallo was unarmed, conclusively establish [the]
    defendants’ guilt and are dispositive of all possible factual and legal issues,’’
    including ‘‘[routine] . . . assertions [by prospective jurors] that [the] defen-
    dants were motivated by racial prejudice’’).
    30
    Although not directly relevant to whether the defendant could get a fair
    trial in New Haven, we also find it significant that Penrod’s study reflected
    extremely high levels of case awareness among potential jurors in Stamford.
    This means that an exercise of discretion to transfer this case to Stamford
    would not have obviated the need for a searching and lengthy voir dire
    process like that employed in New Haven to identify twelve suitable jurors
    plus alternates. That suggests, of course, that transferring the case to Stam-
    ford would not have dramatically reduced obstacles to picking an impartial
    jury or have reduced the need for a searching voir dire process to reach
    that end. See United States v. Tsarnaev, 
    968 F.3d 24
    , 55 (1st Cir. 2020)
    (District Court did not abuse discretion in denying motion to change venue
    of Boston Marathon bombing trial from Boston, Massachusetts, because
    polling data showed ‘‘public awareness and attitudes were not materially
    different in, for example, Springfield or New York City,’’ rendering it ‘‘not
    a case where almost everybody locally knows something and very few
    elsewhere know of it’’), petition for cert. granted (U.S. March 22, 2021) (No.

    Internet, and radio, with entire baseball stadium erupting in cheers when
    he was convicted of related charges in commonwealth court, despite its
    size of three million residents, particularly given that case was ‘‘relatively
    unknown’’ outside of Puerto Rico); United States v. Gordon,

    paper articles and editorials, which strongly support[ed] the view that a
    substantial percentage of Delawarians [were] likely to have concluded that
    the defendants [were] guilty as charged,’’ almost everyone in county where
    alleged crimes occurred had heard about case and substantial majority
    already had formed opinions about it, and case could be tried in nearby
    Philadelphia, where it had ‘‘generated little or no publicity’’ without undue
    inconvenience), rev’d on other grounds,

     (3d Cir. 2006).
    31
    In the present case, the jury found the defendant guilty on all counts,
    rather than having returned a split verdict, the latter of which has been
    deemed indicative of impartiality weighing against the presumption of preju-
    dice. See, e.g., Skilling v. United States, supra, 
    561 U.S. 383
    –84; State v.
    Carr, 
    supra,
     
    300 Kan. 74
    . Nonetheless, our review of the record demonstrates
    that the evidence was overwhelming. Indeed, the defendant conceded the
    vast majority of the factual issues in the guilt phase—in particular, his
    participation in the home invasion—choosing to challenge only whether he
    had sexually assaulted M anally, rather than orally as he had confessed,
    and whether he had the requisite intent to kill. Accordingly, we conclude
    that the jury’s verdict does not support a finding of presumptive prejudice.
    See State v. Townsend, 
    211 Conn. 215
    , 228–29, 
    558 A.2d 669
     (1989) (noting
    that publicity about plea negotiations and defendant’s offer to plead guilty
    to murder in exchange for five year sentence was ‘‘not as inherently prejudi-
    cial as in a case in which a defendant denies any involvement in a crime,
    but nonetheless has considered pleading guilty in exchange for a reduced
    sentence,’’ because defendant did not ‘‘[dispute] the events leading up to
    the victim’s death’’ but, instead, appeared to challenge whether he had ‘‘the
    requisite intent for murder’’); see also Luong v. State, supra, 
    199 So. 3d 148
    (Given ‘‘[the defendant’s] admission that he threw each of his children off
    the bridge, the fact that [the defendant] was not acquitted of any of the
    charged offenses does not either support or rebut a presumption of jury
    bias or impartiality. The evidence in [the] case simply did not create any
    inference from which the jury could conclude that he killed some, but not
    all, of his children.’’); State v. Gribble, supra, 
    165 N.H. 23
     (defendant’s
    admission to participation in crimes and plea of not guilty by reason of
    insanity reduced prejudice from media reporting on coconspirator’s trial
    that ‘‘described the defendant’s involvement in the crime’’ because he ‘‘admit-
    ted as much when he pleaded not guilty by reason of insanity’’).
    32
    The Peterson trial originally was moved from the rural jurisdiction in
    which the murder happened to San Mateo County, which had a larger
    population. See People v. Peterson, supra, 
    10 Cal. 5th 438
    .
    33
    Having concluded that no presumption of prejudice arose on the record
    in this case, we need not directly consider the question of whether any
    such presumption is rebuttable, an issue not resolved by the United States
    Supreme Court in Skilling; see Skilling v. United States, supra, 
    561 U.S. 385
     n.18; and not clearly addressed by that court’s earlier precedents, which
    were inconsistent with respect to whether to examine the transcript of voir
    dire after determining that prejudice existed. See, e.g., United States v.
    Casellas-Toro, supra, 
    807 F.3d 388
    –89. Those few courts that have directly
    considered this issue have, however, concluded that the presumption is in
    fact rebuttable, both before and after Skilling was decided, in a process
    akin to the actual prejudice inquiry. See United States v. Wilcox, 
    631 F.3d 740
    , 749 (5th Cir.), cert. denied, 
    563 U.S. 1015

    We note that the First Circuit recently concluded that the Boston Mara-
    thon bomber, Dzokhar Tsarnaev, was entitled to a new penalty phase trial.
    United States v. Tsarnaev, 
    968 F.3d 24
    , 56 (1st Cir. 2020), petition for cert.
    granted (U.S. March 22, 2021) (No. 20-443). Although the court held that
    the District Court had not abused its discretion in declining to move the
    trial out of Boston, Massachusetts; 
    id.,
     55–56; it also concluded that the
    extent of the voir dire conducted—the presumed adequacy of which had
    been a key to its earlier mandamus decision in In re Tsarnaev, supra, 
    780 F.3d 25
    –26, not to move the trial from Boston—was in fact inadequate to
    ensure the impartiality of the jurors. See 
    id.,
     58–59.
    35
    ‘‘In accordance with our usual practice, we identify jurors by initial[s] in
    order to protect their privacy interests.’’ (Internal quotation marks omitted.)
    State v. Holmes, 
    334 Conn. 202
    , 207 n.6, 
    221 A.3d 407
     (2019).
    36
    With respect to the death penalty, all of the jurors testified that they
    (1) understood the jury’s exclusive role in the sentencing decision, (2) would
    keep an open mind during a sentencing phase despite evidence heard during
    the guilt phase supporting convictions of intentional murder and the sexual
    assault of an eleven year old girl, and (3) would keep an open mind with
    respect to the claimed mitigating factors, including relatively minor involve-
    ment in the crime, reduced mental capacity, and a troubled childhood.
    37
    Out of an abundance of caution, and to give the most expansive consider-
    ation possible to the defendant’s actual prejudice claims, we also reviewed
    the voir dire of the six alternate jurors, along with the three backup alternate
    jurors. See, e.g., State v. Crafts, supra, 
    226 Conn. 260
    . We do not discuss
    them in detail, insofar as ‘‘[p]rejudice is assessed with reference to the jurors
    who [found] the defendant [guilty] because [t]he constitutional standard of
    fairness requires [only] that a defendant have a panel of impartial, indifferent
    jurors.’’ (Internal quotation marks omitted.) State v. Gould, supra, 
    322 Conn. 531
    . None of the six alternates who sat at trial, G.B., C.T., C.H., Ch.G., C.J.,
    and R.D., was needed to deliberate in this case. Similarly, the three backup
    alternate jurors, I.L., M.S., and M.M., were dismissed prior to the start of
    the trial and did not sit with the jury for any part of this case. Our review
    of their voir dire testimony indicates that, consistent with the regular jurors,
    each of the alternates and backup alternates expressed relatively modest
    levels of knowledge about this case and the defendant’s background in
    particular, did not know anything about the defendant’s background, stated
    limited support for the death penalty as a general matter, and had an open
    mind and understanding of the state’s burden of proof with respect to both
    the guilt and penalty phases in this case. We acknowledge, however, that
    the defendant raised challenges for cause to several of these alternate and
    backup alternate jurors based on case knowledge, which the trial court
    rejected on the basis of its assessment of the jurors’ understanding of and
    ability to apply the presumption of innocence; the defendant did not exercise
    peremptory challenges as to any of them. See part I E of this opinion.
    38
    M.N. did not have any personal or professional contacts with W.
    39
    With respect to the death penalty, M.N. believed that ‘‘it’s something
    that should be reserved only for heinous crimes that were done . . . inten-
    tionally and thought out beforehand.’’ He quantified his support for it as a
    three on a scale of one to ten. When asked hypothetically about whether
    the death penalty was ‘‘the only appropriate penalty’’ for a premeditated
    murder, M.N. stated that his view would ‘‘depend on additional details,’’
    such as whether the victim in the hypothetical had suffered ‘‘additional pain
    and torture . . . .’’ When asked about this case, he stated: ‘‘The accused’s
    crimes are horrible, and those are the kind of crimes that I think are the
    ones where the death penalty is appropriate, but I would consider mitigating
    circumstances if I was instructed to do so.’’
    40
    T.A. had ‘‘no qualms with’’ the death penalty because it was provided
    by law, and he quantified his support for it as a five on a scale of one to
    ten. His moderate support for the death penalty was dependent on the
    circumstances of the case. When asked about his ideal world, T.A. stated
    he would not have the death penalty because it is inconsistent with his
    ideals as a social worker to help people after understanding their actions.
    T.A. also acknowledged the need for proof of aggravating and mitigating
    factors, stating that, before making the death penalty decision, he would
    want to know ‘‘what caused that person to do that type of crime or . . .
    his history’’; he believed a person’s past could ‘‘definitely’’ shape his or
    her life.
    41
    T.M. had previous personal experience with homicide trials, having
    testified as an alibi witness at the murder trial of a close friend one decade
    before, at which her friend was convicted.
    42
    T.M. also stated candidly that W’s presence during the proceedings
    ‘‘might’’ influence her by ‘‘putting [herself] in his shoes . . . . I would feel
    bad. I would be hurting for him and with him.’’ The trial court, however,
    credited T.M.’s statement that, although her ‘‘heart goes out to him and his
    family,’’ that sympathy ‘‘wouldn’t influence [her] decision based on what
    happened with the trial . . . .’’
    43
    With respect to the death penalty, T.M. knew from a college research
    project that it is ‘‘expensive.’’ T.M. did not ‘‘feel strongly either . . . way’’
    and was ‘‘in between’’ on the death penalty, although she ‘‘would rather not
    see anybody [get] the death penalty.’’ She characterized her support as a
    three or four on a scale of one to ten, with it being potentially appropriate
    depending on the circumstances of the case.
    44
    K.A. did not know W personally or professionally and could not think
    of any mutual acquaintances.
    45
    When asked about the death penalty, K.A. stated her ‘‘ethical’’ opinion
    that ‘‘it is not a good solution to [crime] in our country or anywhere.’’ She
    placed her support of it at a five on a scale of one to ten. Nevertheless,
    K.A. stated she did not know it was ‘‘a legal issue’’ and, consistent with her
    desire to be ‘‘fairly objective in [her] day-to-day activities,’’ emphasized
    that she could follow the instructions of the court because ‘‘I believe in
    our system.’’
    46
    We note that V.K. was the last prospective juror of the day on April
    7, 2011, but that the transcript of her voir dire is apparently incomplete,
    proceeding directly to adjournment from the defendant’s questioning of her.
    There is no transcript of V.K.’s being accepted as a juror or the trial court’s
    instructions to her. Neither party has claimed, however, that this omission
    has rendered the record inadequate for review or that there was a challenge
    to the qualification of V.K.—or any other regular juror—to serve.
    47
    With respect to the death penalty, V.K. had not ‘‘really . . . thought
    about it,’’ but she described her support for it as ‘‘in the middle,’’ quantified
    as a five on a scale of one to ten. When asked whether she believed that
    the death penalty could be appropriate in some cases, V.K. stated that ‘‘it
    would really matter on what the case . . . was . . . .’’ When asked whether
    she could think of a situation herself in which the death penalty would be
    appropriate, V.K. stated that ‘‘I really . . . can’t answer that. I really don’t
    know.’’ When asked to consider whether she would impose the death penalty
    in the case of a horrendous crime, she replied in the negative ‘‘because I
    don’t really believe in killing somebody like for an eye for an eye kind of . . .
    philosophy . . . .’’ Nevertheless, V.K. also stated that she could imagine a
    situation in which the evidence would support a vote for the death penalty
    and that she would follow the instructions of the court and apply them to
    the evidence.
    48
    M.B. testified that she had ‘‘mixed feelings’’ about the death penalty,
    describing it as a ‘‘weighty’’ and ‘‘very difficult’’ decision. She quantified her
    support for the death penalty as a five or six on a scale of one to ten but
    stated that she would not have it in a country where she made the law.
    Although M.B.’s husband favored the death penalty, including for the defen-
    dant, she testified that his belief would not influence her because ‘‘I have
    a strong sense of myself.’’
    49
    With respect to the death penalty, L.C. stated that, ‘‘in the past, I was
    not in favor of it’’ because she questioned whether it was ‘‘morally right
    for us as a society to put someone to death,’’ but she had become more
    ‘‘ambivalent’’ about the issue over time. She quantified her current support
    for the death penalty as a five on a scale of one to ten, acknowledging that
    there might be some extreme situations in which the death penalty could
    be appropriate, but emphasized her ‘‘hope that I could be very sure that
    . . . it was beyond any reasonable doubt.’’ When asked by defense counsel,
    L.C. stated that her change in opinion about the death penalty had nothing
    to do with this case.
    50
    R.F. believed that the death penalty ‘‘should be used on . . . a case-
    by-case basis,’’ for serious cases such as those involving ‘‘several murders,
    maybe like Ted Bundy,’’ with his support for the death penalty being ‘‘a five
    or a six’’ on a scale of one to ten. R.F. had not given a lot of ‘‘serious
    thought’’ to the legality or morality of the death penalty or the pending
    public policy debate. He personally believed that the death penalty did not
    serve a ‘‘legitimate purpose’’ because he viewed life in prison as potentially
    worse, based on what he had seen of prisons on television.
    51
    With respect to the death penalty, L.K. stated that she could follow the
    law and make the ‘‘right decision,’’ but that she had ‘‘always . . . felt’’ that
    she was not personally ‘‘a big supporter of it . . . .’’ L.K. quantified her
    support for the death penalty as a three or four on a scale of one to ten,
    observing that, although ‘‘there are certain crimes that it definitely fits,’’ she
    was concerned about the imperfection of the criminal justice system and
    making sure that innocent people were not executed. She emphasized that
    she did not ‘‘think that death is the only appropriate punishment,’’ deeming
    that decision dependent ‘‘on . . . the situation, based on mitigating factors,’’
    and stated that ‘‘I do not think that I would walk in and because . . . people
    had been murdered just say that the death penalty was the option.’’
    52
    With respect to the death penalty, S.H. testified that ‘‘I guess debates
    [have] been going on for years with that. I don’t feel on or off about it.’’ He
    clarified that he did not ‘‘have an opinion to weigh either way’’ on the issue
    and lacked sufficient knowledge to quantify his support on a scale of one
    to ten. S.H. testified that he would be able to participate in a death penalty
    deliberation, including a vote to impose either it or a life sentence, but
    would have to ‘‘hear argument’’ about it.
    53
    J.H. described herself as ‘‘on the fence’’ about the death penalty because
    of her Catholic faith; she acknowledged that, ‘‘if a personal tragedy did
    happen to me, I can’t say how I would react in that circumstance.’’ She
    quantified her support for the death penalty as a five on a scale of one to
    ten, calling it a ‘‘difficult question’’ that she never had to consider before.
    If given a choice to create her own laws, J.H. said ‘‘it would be hard for
    me to enact the death penalty.’’ J.H. further testified that she was ‘‘really
    undecided’’ about the death penalty morally but could follow the law and
    return a death verdict if ‘‘that was the appropriate penalty,’’ although she
    recognized that ‘‘it will be very difficult to be in this position.’’
    54
    With respect to the death penalty, C.A. had ‘‘periodically’’ engaged in
    discussions of it over the years, and he did ‘‘not believe in the death penalty
    except for cases . . . with very extreme circumstances.’’ He quantified his
    support for the death penalty as a five on a scale of one to ten, stating that
    he had become less supportive of the death penalty as he got older, perhaps
    because of his Catholic faith. C.A. believed that the state should have the
    power to kill a citizen only under ‘‘certain circumstances,’’ such as for crimes
    that are ‘‘[v]ery heinous in nature, and I think each case . . . or each situa-
    tion is different . . . I think you have to listen to . . . the facts and then
    bear judgment on it, but to put a blanket statement over, you know, would
    you do it here and not there? I think that has to be handled very care-
    fully . . . .’’
    55
    Specifically, the defendant claims that the trial court improperly denied
    his challenges for cause to prospective jurors E.M., C.G., V.J., P.L., S.W.,
    W.V., B.F.-S., M.C., S (no first name indicated), J.W., J.P., and C.P., thus
    requiring him to expend peremptory challenges on them.
    56
    We note ‘‘the sources in our law of the defendant’s right to an impartial
    jury and his correlative right to have a biased venireperson removed for
    cause. Both the federal and state constitutions guarantee to an accused the
    right to a public trial by an impartial jury. U.S. Const., amends. VI and XIV;
    Conn. Const., art. I, § 8. Furthermore, General Statutes § 54-82f provides in
    relevant part: ‘If the judge before whom the [voir dire] examination is held
    is of the opinion from the examination that any juror would be unable to
    render a fair and impartial verdict, the juror shall be excused by the judge
    from any further service upon the panel, or in the action, as the judge
    determines.’ ’’ State v. Esposito, supra, 
    223 Conn. 308
    –309; see also Practice
    Book § 42-12 (providing language substantially identical to § 54-82f). ‘‘[T]he
    trial court is vested with wide discretion in determining the competency of
    jurors to serve, and that judgment will not be disturbed absent a showing
    of an abuse of discretion. . . . In exercising this discretion the trial court
    must zealously protect the rights of the accused.’’ (Citation omitted; internal
    quotation marks omitted.) State v. Esposito, supra, 310.
    57
    To the extent that the defendant claims that he was prejudiced because
    he was required to exhaust his allotted peremptory challenges on these
    jurors prior to the conclusion of jury selection, thus depriving him of the
    opportunity to use those challenges on other jurors whom he also deemed
    objectionable, thereby affecting the composition of the panel as a whole,
    this claim is foreclosed by our decision in State v. Ross, supra, 
    269 Conn. 233
    –34. See also State v. Pelletier, supra, 
    209 Conn. 572
    –73 (‘‘[T]he defendant
    did not accept any juror or alternate whom he requested to be removed for
    cause. Therefore, even if those prospective jurors were biased, the defendant
    was not harmed because those individuals never became members of the
    jury.’’).
    58
    Section 8-6 of the Connecticut Code of Evidence provides: ‘‘The follow-
    ing are not excluded by the hearsay rule if the declarant is unavailable as
    a witness . . . (4) Statement against penal interest. A trustworthy statement
    against penal interest that, at the time of its making, so far tended to subject
    the declarant to criminal liability that a reasonable person in the declarant’s
    position would not have made the statement unless the person believed it
    to be true. In determining the trustworthiness of a statement against penal
    interest, the court shall consider (A) the time the statement was made
    and the person to whom the statement was made, (B) the existence of
    corroborating evidence in the case, and (C) the extent to which the statement
    was against the declarant’s penal interest. . . .’’
    59
    After closing arguments, the trial court readdressed the parties with
    respect to the letters. The court stated that it would review the letters and
    then hear arguments the next day from the parties as to their admissibility,
    as well as any desired relief. Consistent with its directive from earlier in
    the day, the trial court then charged the jury, but it did not submit the case
    to the jury for deliberation at that time.
    60
    When asked by the trial court, defense counsel indicated that he had
    not yet spoken with Hayes’ attorneys, but he agreed with the trial court’s
    observation that ‘‘[i]t’s hard to imagine [Hayes] not taking the fifth amend-
    ment . . . .’’
    61
    The defendant emphasized that the police had found numerous pairs
    of female sneakers when they searched Hayes’ home and had found H’s
    sneakers in Hayes’ vehicle, which was consistent with his ‘‘constantly’’
    talking in the letters about his sneaker fetish and the fact that he claimed
    to have taken sneakers as trophies in connection with his past murders.
    The defendant also contended that Hayes’ descriptions of himself as a ‘‘great
    hunter’’ and Hayes’ statements of sadistic pleasure supported the defendant’s
    theory that he personally lacked intent to kill during the home invasion.
    62
    In its colloquy with defense counsel, the trial court described the letters
    as, ‘‘at a minimum, a bare minimum, a mixed blessing for you because, if
    you view . . . Hayes as truthful, he is one of the great serial killers [in]
    modern American history. He claims to have killed seventeen people prior
    to this incident in pretty horrific ways, but he also says extremely, and I
    mean extremely, inculpatory things about [the defendant such] that it would
    be hard to imagine you wanting to put on. He says that [the defendant] had
    the proper evil intent, he says that [the defendant] poured gas on [the
    victims] and set the fire.’’ The court further observed that Hayes had written
    that the defendant ‘‘said, suppose we’re going to kill everybody anyway,
    this is at an early stage, he says that [the defendant] announces that he is
    going to sexually assault the eleven year old girl which later on . . . Hayes
    purports to have personally witnessed. He says that . . . [the defendant]
    was the one who actually killed the girls. And he says that they went into
    this enterprise with the . . . joint plan of killing everybody. So, under these
    circumstances, I just don’t see how, if it’s true, that it helps you at all, and,
    of course, if it’s not true, then I don’t see how it could be relevant.’’ Although
    defense counsel demurred, stating that ‘‘I don’t believe it’s appropriate for
    me to address trial tactics with the court in a public forum,’’ the trial court
    emphasized that the information was ‘‘necessary for [it] to address this
    question because the evidence has closed’’ and could only ‘‘reopen . . . to
    avoid a miscarriage of justice.’’ The trial court questioned how these ‘‘damn-
    ing things’’ in the letters would mean that reopening ‘‘would avoid a miscar-
    riage of justice . . . .’’ The trial court acknowledged that, if ‘‘hypothetically
    . . . Hayes had committed seventeen murders prior to this event, how you
    could argue from that that Hayes was the leader’’; however, the letters also
    stated that the defendant himself had told Hayes that ‘‘he had killed before,’’
    making it ‘‘very hard for [the court] to term this as exculpatory.’’
    63
    The trial court did, however, leave open the possibility that the letters
    could be admissible ‘‘in the penalty phase of the trial should we, hypotheti-
    cally, get there,’’ given the relaxed rules of evidence in that stage of the pro-
    ceedings.
    64
    We agree with the trial court’s observation that, assuming that Hayes
    was unavailable to testify, the admissibility of his letters as declarations
    against penal interest was nevertheless highly doubtful, given that (1) they
    were written four years after the crimes to a woman whom Hayes understood
    to be simpatico in his passions for evil, and (2) there was no apparent
    corroboration of times, dates or places of his claimed prior seventeen homi-
    cides. See State v. Bryant, 
    202 Conn. 676
    , 699, 
    523 A.2d 451
     (1987) (‘‘the
    focus on time appears to arise from the belief that declarations made soon
    after the crime suggest more reliability than those made after a lapse of
    time [during which] a declarant has a more ample opportunity for reflection
    and contrivance’’). Compare State v. Snelgrove, 
    288 Conn. 742
    , 769–70, 
    954 A.2d 165
     (2008) (third party’s statement to fellow inmate that he had killed
    victim was inadmissible when third party ‘‘was suffering from psychiatric
    problems at the time that he made the statement,’’ which lacked corrobora-
    tion and was made two to three years after murder and defendant’s arrest),
    with State v. Rivera, 
    268 Conn. 351
    , 369–71, 
    844 A.2d 191
     (2004) (dual
    inculpatory statement was admissible when made to close family member
    in confidence, on his own initiative, and within five months of homicide).
    65
    Although the defendant suggests that the prejudicial portions of the
    Hayes letters could have been redacted, the state accurately notes that the
    defendant did not raise the possibility of redaction before the trial court. This
    precludes us from considering the possibility of redaction in determining
    whether the trial court abused its discretion in denying the defendant’s
    motions. In any event, as the state also points out, redaction of the portions
    that were prejudicial to the defendant might well have affected the context
    of the remaining statements in a manner inconsistent with our case law
    governing the admission of declarations against penal interest. See, e.g.,
    State v. Bryant, 
    202 Conn. 676
    , 696–97, 
    523 A.2d 451
     (1987) (‘‘where the
    disserving parts of a statement are intertwined with self-serving parts, it is
    more prudential to admit the entire statement and let the trier of fact assess
    its evidentiary quality in the complete context’’).
    66
    Winters testified that he used software that allowed him to ‘‘mark’’ or
    ‘‘tag’’ recordings of various individual transmissions on the telephone and
    radio systems, and then to move them into another software application
    that would ‘‘recreate the incident.’’ After reviewing the various telephone
    lines and radio channels, Winters moved the calls that he had tagged as
    relevant to the software application; he then created a compact disc (CD)
    for Vignola that contained those communications. Winters also created, at
    Vignola’s request, a written log that summarized, but did not transcribe
    verbatim, the time and nature of the communications. This process depended
    on Winters’ judgment to determine the relevance of each communication.
    Winters testified that the system did not automatically back up the
    recordings, and he manually copied the sound files to CDs on a weekly
    basis as a backup. Several years later, the town replaced the Cheshire
    emergency communications system after it was severely damaged by a
    lightning strike in December, 2010. When he subsequently received a request
    for a review of additional communications in connection with the motions
    for augmentation in this case, Winters stated that the originals had been
    destroyed by the lighting strike, but he was able to review the backup drives
    that he had created, which were stored off-site at Cheshire’s town hall. See
    footnote 67 of this opinion. He did not, however, remember the existence
    of those drives at the time that defense counsel had made the initial request
    for additional communications in 2011.
    67
    Appellate counsel observed that the calls described in the Hartford
    Courant article were not identified in the call log and discovery memorandum
    that the state had produced prior to trial. She could not find any evidence
    of those communications after she searched the files of all three attorneys
    who had represented the defendant at trial and listened to the CDs that she
    found therein. She then contacted Neil Dryfe, the chief of the Cheshire
    police, who produced a flash drive of those calls, which had been found in
    a backup storage location in town hall. See footnote 66 of this opinion.
    Appellate counsel testified, however, that she subsequently learned that the
    recordings of the missing communications had in fact been produced to
    attorneys for Hayes, who was tried first.
    68
    ‘‘Pursuant to State v. Floyd, supra, 
    253 Conn. 700
    , a trial court may
    conduct a posttrial evidentiary hearing to explore claims of potential Brady
    violations . . . when a defendant was precluded from perfecting the record
    due to new information obtained after judgment. . . . In order to warrant
    such a hearing, a defendant must produce prima facie evidence, direct or
    circumstantial, of a Brady violation unascertainable at trial. . . . The trial
    court’s decision with respect to whether to hold a Floyd hearing is reviewable
    by motion for review pursuant to Practice Book § 66-7 . . . .’’ (Citations
    omitted; internal quotation marks omitted.) State v. Ouellette, 
    295 Conn. 173
    , 182 n.7, 
    989 A.2d 1048
     (2010).
    69
    In particular, the defendant claimed that the inadequacy of the police
    response was a relevant circumstance in this case for consideration by the
    jury in its capital sentencing determination. At the Floyd hearing, Todd
    Bussert, who was one of the attorneys who represented the defendant at
    trial, testified that he had reviewed the CD of dispatch calls found in his
    trial file in advance of cross-examining Vignola, the Cheshire police detective
    captain. The defense strategy, in connection with ‘‘front-load[ing]’’ mitigation
    for the anticipated penalty phase, was to raise the question of whether the
    tragedy might not have occurred if the Cheshire police had responded
    differently. Bussert’s objective in cross-examining Vignola was to establish
    the sequence of the police response and to demonstrate that the Cheshire
    police ‘‘didn’t actually engage anyone; they just kind of set up a perimeter.’’
    70
    At the Floyd hearing, the trial court also considered a separate augmen-
    tation and rectification motion filed on November 13, 2015, that encom-
    passed certain testimony and exhibits from Hayes’ trial with respect to the
    photographs that the defendant had taken of M. We address the defendant’s
    claims relating to those items in part IV of this opinion.
    71
    As described in the stipulation, the relevant recordings are (1) ‘‘[a]
    recording numbered 173251 (CH10 09001C58) [in] the call log provided by
    the [s]tate to defense trial counsel and admitted at trial as [d]efendant’s
    [e]xhibit #A. Call from Cheshire Police Sergeant Chris Cote to Officer Robert
    Regan, acting as dispatcher, in response to request of Officer Donald Miller
    for a call,’’ (2) ‘‘[a] recording numbered 173309 (CH1 000A724) [in] the call
    log provided by the [s]tate to defense trial counsel and admitted at trial as
    [d]efendant’s [e]xhibit #A in which Cheshire Police Captain Robert Vignola
    states he will do a drive-by of 300 Sorghum Mill Drive, Cheshire, and the
    house is described by Officer Philip Giampietro,’’ (3) ‘‘[a] recording desig-
    nated CH10 09001CCB 669; in which Shawn Patterson, a Cheshire [p]olice
    [o]fficer, speaks with Officer Brian Schechter,’’ (4) ‘‘[a] recording designated
    CH10 09001D4C 669; the relevant speakers are a Cheshire Detective Kerry
    Nastri and . . . Connecticut State Trooper David Devito,’’ (5) ‘‘[a] recording
    designated CH11 0A00327B; the relevant speaker is Cheshire Police Captain
    . . . Vignola; internal call from Captain Ren Marchand, shift commander.
    The time of the call was 9:27:52 a.m. on July 23, 2007,’’ (6) ‘‘[a] recording
    designated CH17 10002AA5; the relevant speaker is Cheshire Police Officer
    Jeff Sutherland. The time of the call was 9:33:26 a.m. on July 23, 2007. This
    call was included on a dis[c] produced in discovery on or around September
    13, 2007 (Item #87). It is included among other calls in Call #173292 [in] the
    call log, [d]efense [e]xhibit A,’’ (7) ‘‘[a] recording designated
    CH17 10002AA7. The time of the call was 9:35:23 a.m. on July 23, 2007. This
    call was included on a dis[c] produced in discovery on or about September
    13, 2007 (Item #87). It is included among other calls in Call #173292 [in] the
    call log, [d]efense [e]xhibit A,’’ and (8) ‘‘[a] recording designated
    CH10 09001C57 (Time: 9:23:12); the relevant speakers are [Officer Regan]
    and Cheshire Police Lieutenant Joe Mazzini. The time of the call was 9:23:12
    a.m. on July 23, 2007.’’
    72
    The defendant withdrew claims arising from the 9:33:26 a.m. broadcast
    by Cote indicating that he was approaching Sorghum Mill Drive and the
    9:35:23 a.m. broadcast by an officer who sounded like Cote, indicating that
    he was on the rear side of the P family residence at that time.
    73
    Section 9-1 (a) of the Connecticut Code of Evidence provides: ‘‘The
    requirement of authentication as a condition precedent to admissibility is
    satisfied by evidence sufficient to support a finding that the offered evidence
    is what its proponent claims it to be.’’
    74
    Section 7-1 of the Connecticut Code of Evidence provides: ‘‘If a witness
    is not testifying as an expert, the witness may not testify in the form of an
    opinion, unless the opinion is rationally based on the perception of the
    witness and is helpful to a clear understanding of the testimony of the
    witness or the determination of a fact in issue.’’
    75
    C.H.-R. testified that she originally thought that the e-mail had been
    created by the Cheshire police and forwarded to her by her brother-in-law,
    W. C.H.-R. later asked W about the e-mail around the time of trial, and W
    denied sending the e-mail to her or having any awareness of the informa-
    tion therein.
    76
    C.H.-R. testified that she had discussed the police response with Vitello,
    who stated that he could not speak to her about the evidence until after
    the trial; she had informed him of her concern that the police were present
    when the Pacifica returned. She also discussed her concerns about the
    police response with the prosecutor before the trial, although none of the
    reports that he had showed them included the initial police response time.
    Sage, an inspector with the prosecutor’s office, counseled C.H.-R. not to
    discuss the information publicly until after the trial.
    77
    Section 10-3 of the Connecticut Code of Evidence provides: ‘‘The original
    of a writing, recording or photograph is not required, and other evidence
    of the contents of such writing, recording or photograph is admissible if:
    ‘‘(1) Originals lost or destroyed. All originals are lost or have been
    destroyed, unless the proponent destroyed or otherwise failed to produce
    the originals for the purpose of avoiding production of an original; or
    ‘‘(2) Original not obtainable. No original can be obtained by any reasonably
    available judicial process or procedure; or
    ‘‘(3) Original in possession of opponent. At a time when an original was
    under the control of the party against whom it is offered, that party was
    put on notice, by the pleadings or otherwise, that the contents would be a
    subject of proof at the proceeding, and that party does not produce the
    original at the proceeding; or
    ‘‘(4) Collateral matters. The contents relate to a collateral matter.’’
    78
    Accordingly, we agree with the trial court that the issue presented in
    this case, which concerned the existence of both the missing e-mail and
    the call log contained therein, is—contrary to the defendant’s argument—
    distinct from the authentication inquiry governed by § 9-1 of the Connecticut
    Code of Evidence, under which the trial court exercises its discretion in
    determining whether there is a prima facie case showing that a specific
    item of evidence is what its proponent claims it to be. See, e.g., State v.
    Carpenter, 
    275 Conn. 785
    , 856–57, 
    882 A.2d 604
     (2005) (authentication of
    identity of speaker on recording), cert. denied, 
    547 U.S. 1025
    , 
    126 S. Ct. 1578
    , 
    164 L. Ed. 2d 309
     (2006); State v. Colon, supra, 
    272 Conn. 188
    –89
    (authentication of written confession to police). This authentication inquiry
    would have arisen in the present case had, for example, the e-mail itself
    been presented to the trial court, thus requiring the trial court to consider
    the authenticity of both the e-mail and the call log contained therein.
    79
    The recording of the first communication provides in relevant part: ‘‘[A
    Male Voice]: Hey, what’s up?
    ‘‘ [A Male Voice]: We’re taking 911s from the bank. Apparently some family
    is tied up and being held hostage, and they’re forcing the woman to go to
    the bank and withdraw a large amount of cash to pay the captors. Mazzini
    is here now. Don is getting basic information on it, but it sounds like we
    might be in this for a little bit.
    ‘‘[A Male Voice]: All right. Where is it?
    ‘‘[A Male Voice]: The lady is at Bank of America, Don? The lady just left,
    possibly with the captors in a Chrysler Pacifica heading out Vespucci’s side
    of Maplecroft.
    ‘‘[A Male Voice]: Do you want to put that on the air? Joe, what do you
    want to do? Do you want to try to find that car or what do you want to
    do? We’re going to put that out on [indiscernible]. Just left Bank of America,
    the captors might be in the car with her, Chrysler Pacifica. . . . The bank
    manager is the one that called us. The lady doesn’t even—didn’t want to
    notify the police because they have her family tied up. [Indiscernible.]
    ***
    ‘‘[A Male Voice]: . . . Chrysler Pacifica, color gray, coming out of
    Maplecroft Plaza [indiscernible] West Main Street toward Sorghum Mill
    Road.
    ‘‘[A Male Voice]: All right. What color is the Pacifica? . . .
    ‘‘[A Male Voice]: . . . [Indiscernible] But—why don’t you just head down
    toward that area and see if we can intercept this car.
    ‘‘[A Male Voice]: I’m on Maple now. . . . [Indiscernible.] Turned onto
    West Main Street, the Pacifica [indiscernible] gray Pacifica. . . .’’
    80
    The recording of the second communication provides: ‘‘[A Male Voice]:
    300 Sorghum Mills? . . . Is the lady still at the bank? . . . Chrysler Pacif-
    ica? . . . All right. We’re heading out.’’
    81
    The recording of the third communication provides in relevant part: ‘‘[A
    Male Voice]: [Indiscernible.] Going to do a drive-by [indiscernible] . . . .
    ‘‘[A Male Voice]: Okay, as soon as you get past Hotchkiss Ridge, just look
    on your left, you’ll see the house. Again, the front faces Hotchkiss Ridge,
    the driveway comes out onto Sorghum. The vehicle is in the driveway.’’
    82
    The recording of the fourth communication provides in relevant part:
    ‘‘[A Male Voice]: I need to know whether you want me in or not. I’m the
    hostage negotiator, and I got paged. . . .’’
    ‘‘[A Male Voice]: Not at this time. . . .’’
    83
    The recording of the fifth communication provides in relevant part: ‘‘[A
    Male Voice]: We want to know, Brian and I are out on West Johnson . . .
    [indiscernible] if you want us to come in and start suiting up?
    ‘‘[A Male Voice]: We’ll call you if we need anything—if we need you.’’
    84
    The recording of the sixth communication provides in relevant part:
    ‘‘[A Male Voice]: All right. Did you get that so far? . . . Apparently she
    came into the bank, she tried to get some money out. . . . One of the
    accounts was in the husband’s name, and then she says, well, my kids are
    at home tied up, so we don’t know if they really are or if she was just trying
    to get money out of the bank at this point. . . . The car is at the house
    from what I understand.
    ‘‘The car is at the house. She got $15,000 in cash in three envelopes with
    $5000 a piece. They’re all strapped. So $15,000 dollars in $50 bills.’’
    85
    We note that the defendant argued that the officers had watched him
    when he went into the bathroom at the police station to make sure that he
    did not wash himself, and that the swab had in fact detected the defendant’s
    sperm on his penis, which was consistent with his account in his statement
    that he ejaculated after committing an oral sexual assault on M. Although
    the defense acknowledged Carver’s testimony that the lack of physical injury
    was not inconsistent with sexual assault, the defense contended that it was
    unlikely given the size differences between M and the defendant, along with
    the lack of consent.
    In rebuttal, the state emphasized that there was no support for the defense
    theory because it was Carver himself who had taken the swab from M and
    not a technician. The state also reemphasized Carver’s testimony about the
    elasticity of the anus rendering the lack of injury to the area ‘‘not unusual
    . . . .’’ Finally, the state emphasized that there was no evidence that the
    police had supervised the defendant while he was in the bathroom at the
    police station, which would support the state’s argument that he had the
    opportunity to wash his penis while in there, along with the fact that the
    swabs were not taken from the defendant until at least fifteen hours after
    his arrest. On this point, Vitello testified on cross-examination that the police
    had provided the defendant with a bathroom break during the interview;
    no one went in the bathroom with him, but they left the door partially ajar.
    86
    In the first communication, the following exchange occurred between
    Patterson and Officer Brian Schechter: ‘‘[Patterson]: I was talking to the—
    I was with the detective when he was talking. That kid is like, there is
    nobody home, dude.
    ‘‘[Schechter]: Which one? The older one or the younger one?
    ‘‘[Patterson]: The younger one. The darker haired dude.
    ‘‘[Schechter]: Really?
    ‘‘[Patterson]: There is nobody . . . that dude is fucking simple as they
    come.’’
    87
    Specifically, Patterson testified at the Floyd hearing that he had been
    called to the station around noon on July 23, 2007, to help cover ‘‘routine
    calls’’ in Cheshire in the aftermath of the incident; he had no role in
    responding to the P home that morning. While standing in a hallway near
    a bulletin board, Patterson observed the defendant for several seconds being
    escorted by several detectives into the booking area. Patterson did not
    participate in any interviews of or have any conversations with the defendant
    at any time. He recalled making the comment to a fellow officer about the
    defendant that was captured on the recording, describing his observation
    that ‘‘no one was home’’ ‘‘and ‘‘simple as they come’’ as reflecting what he
    felt was a lack of emotion that was unusual for a person who had just
    been arrested.

    Neither Nastri nor Devito testified at the Floyd hearing, and the trial
    court did not make any finding as to which speaker made the ‘‘looked evil’’
    comment. Although the defendant argues that Nastri made the ‘‘looked evil’’
    comment, the state disagrees, observing that the flow of the conversation
    demonstrates that it was Devito who had made the observation, given that
    there was no evidence that Devito had responded to the scene, and Cheshire
    Police Lieutenant Jay Markella testified at trial that Nastri had responded
    to the scene and entered the house with him as part of the department’s
    special response team.

    The second communication consisted of the following conversation:
    ‘‘[A Male Voice]: Did the officers get hurt in the cars at all?
    ‘‘[A Male Voice]: No, they were not in the cars.
    ‘‘[A Male Voice]: The cars looked wrecked.
    ‘‘[A Male Voice]: Oh they—they are.
    ‘‘[A Male Voice]: They are totaled, right?
    ‘‘[A Male Voice]: They are totaled. . . . They had placed the cars so that
    no one would drive into the area, and there was a little gap between them,
    and the guy tried to—
    ‘‘[A Male Voice]: Oh, I see what he did . . . he tried to park [indiscernible].
    . . . He hit them hard, huh?
    ‘‘[A Male Voice]: Oh yeah. . . . And they—I’m sure their car, you know
    the victim’s car was—
    ‘‘[A Male Voice]: I saw the troop. I saw the troop. . . . I saw the two
    dirtbag cars. . . . There was a red pickup and there was like a minivan.
    ‘‘[A Male Voice]: Yeah.
    ‘‘[A Male Voice]: I think that those are the two scumbags.
    ‘‘[A Male Voice]: Yup.
    ‘‘[A Male Voice]: Wow, I mean that—the older guy just looked evil.
    ‘‘[A Male Voice]: Yeah?
    ‘‘[A Male Voice]: He just looked evil. I mean you got—you know what?
    Your heart just breaks as an officer watching that stuff. You know—I mean
    it’s heartbreaking for all of us to investigate it. You know? Cuz we have
    families and all that crap too you know.
    ‘‘[A Male Voice]: Well we have—Out of all the guys that went in . . . I
    think I was probably the only one who didn’t have children . . . and we
    have [employee assistance programming] coming in tomorrow. . . .’’
    90
    Defense counsel objected to state’s exhibit 209 on the ground that its
    prejudicial effect outweighed its probative value. The trial court overruled
    that objection. The defendant does not challenge that ruling in this appeal.
    91
    Brunetti determined that all six of the photographs depicted the same
    person, despite the fact that ‘‘the last image is more of an image that’s a
    close-up photograph,’’ which did not contain ‘‘a lot of the surrounding area
    that you see in the previous five images . . . .’’ Brunetti based his opinion
    on ‘‘some telltale signs that . . . led [him] to the conclusion that it was
    the same person. And the last photograph, what’s consistent about that
    photograph, as compared to two or three of the other images, is that the
    person in the last photograph has some type of a cloth over the upper face
    chest area that proceeds under the left arm, and the arm’s bent back,
    apparently past the head, and you could see the cloth going out, and it’s
    consistent [in] both of those photographs. In addition, the female that’s in
    that photograph has pretty much a pronounced chest cavity when she’s
    lying on her back, you could see the bones of her chest cavity and they are
    consistent in both those images also.’’
    92
    During the pendency of this appeal, on November 13, 2015, the defendant
    filed a motion to augment the record pursuant to, inter alia, State v. Floyd,
    supra, 
    253 Conn. 700
    , to add to the record in this case a transcript of
    Farnham’s testimony at Hayes’ trial, along with the unredacted counterpart
    to state’s exhibit 209 at Hayes’ trial under seal. The defendant argued that
    this augmentation was necessary to establish a violation of Napue v. Illinois,
    
    supra,
     
    360 U.S. 264
    , and its progeny. After a hearing, the trial court granted
    the defendant’s motion over the state’s objection and added the transcript
    and a copy of the exhibit—the authenticity of which was stipulated by all
    counsel—to the record for purposes of this appeal. This court subsequently
    upheld that decision when it granted a motion for review filed by the state
    but denied the relief requested.
    93
    Accordingly, we need not consider the state’s arguments that (1) the
    testimony at issue constituted a mere inconsistency in opinion that did not
    rise to the level of false or misleading testimony, and (2) there was no due
    process violation because the defendant was aware of the claimed falsity
    through his review of the Hayes’ trial record during trial preparation, and
    was not precluded from responding to it. But see Gomez v. Commissioner
    of Correction, 
    supra,
     
    336 Conn. 189
    –90 (stating that, ‘‘although the burden
    is one shared by defense counsel and the trial court, the onus ultimately is
    on the prosecutor to not knowingly seek a conviction on the basis of false
    testimony and, should a state’s witness testify falsely, to take such remedial
    measures before the jury retires as are necessary to ensure that it is not
    deceived,’’ and adopting case-by-case multifactor approach to whether case
    is ‘‘[an] exceptional [one] in which disclosure to defense counsel, standing
    alone, is sufficient to satisfy a prosecutor’s obligations and to vindicate a
    defendant’s rights under Napue’’). We also need not consider the state’s
    request that we reconsider our decision on the motion for review upholding
    the trial court’s decision to grant the defendant’s request to make Farnham’s
    testimony at Hayes’ trial and the unredacted photograph part of the trial
    record in this case. See footnote 92 of this opinion.
    94
    We acknowledge, as the defendant argues, that his claim regarding his
    estimation of M’s age was discussed at closing argument in the context of
    the state’s attack on the credibility of his statements that he did not pour
    the gasoline, intend anyone to be killed, or sexually assault M anally.
    Although the state argued that these assertions, which included an attack
    on the defendant’s claimed belief that M was fourteen to sixteen years old,
    lacked credibility, its argument was not based on the photographs but,
    instead, focused on the likely content of the conversation about summer
    plans and school that the defendant claimed to have had with M.
    95
    ‘‘The doctrines of mootness and ripeness both implicate justiciability.
    . . . Mootness implicates this court’s subject matter jurisdiction, raising a
    question of law over which we exercise plenary review. . . . An issue is
    moot when the court can no longer grant any practical relief. . . . [T]he
    rationale behind the ripeness requirement is to prevent the courts, through
    avoidance of premature adjudication, from entangling themselves in abstract
    disagreements . . . . Accordingly, in determining whether a case is ripe, a
    . . . court must be satisfied that the case before [it] does not present a
    hypothetical injury or a claim contingent [on] some event that has not and
    indeed may never transpire.’’ (Citations omitted; internal quotation marks
    omitted.) State v. Campbell, supra, 
    328 Conn. 463
    .
    96
    We note that, while this appeal was pending before this court, the United
    States Court of Appeals for the Second Circuit issued its decision in Reynolds
    v. Quiros, 
    990 F.3d 286
     (2d Cir. 2021), which considered a variety of constitu-
    tional challenges to § 18-10b brought by Richard Reynolds, a former death
    row inmate who had been resentenced under that statute following this
    court’s decision in State v. Santiago, supra, 
    318 Conn. 1
    . In Reynolds, the
    Second Circuit held that (1) § 18-10b is an unlawful bill of attainder in
    violation of article I, § 10, of the United States constitution, and (2) the risk
    classification imposed on Reynolds by the defendants, who are numerous
    officials of the department, violated his rights under the equal protection
    clause of the fourteenth amendment to the United States constitution
    because the defendants failed to establish a rational basis for why he was
    classified more strictly than similarly situated former death row inmates.
    See Reynolds v. Quiros, supra, 300, 301. The Second Circuit also held,
    however, that the United States District Court for the District of Connecticut
    had improperly granted Reynolds’ motion for summary judgment with
    respect to his eighth amendment and due process claims by deciding genuine
    issues of material fact about whether his conditions of confinement, pursuant
    to § 18-10b, in the Special Circumstances Unit at Northern Correctional
    Institution were in fact ‘‘properly characterized as ‘solitary confinement.’ ’’
    Id., 294. We emphasize that our dismissal of the defendant’s appeal with
    respect to his conditions of confinement claim is without prejudice to any
    facial or as applied challenges to § 18-10b that he may bring in a subse-
    quent proceeding.
