    CARVAUGHN JOHNSON v. COMMISSIONER
    OF CORRECTION
    (AC 36185)
    Beach, Keller and Mullins, Js.
    Argued December 10, 2015—officially released June 14, 2016
    (Appeal from Superior Court, judicial district of
    Tolland, Cobb, J.)
    James A. Killen, senior assistant state’s attorney,
    with whom, on the brief, were Michael Dearington,
    state’s attorney, and Adrienne Maciulewski, deputy
    assistant state’s attorney, for the appellant
    (respondent).
    Damon A. R. Kirschbaum, with whom, on the brief,
    was Vishal K. Garg, for the appellee (petitioner).
    Opinion
    KELLER, J. Upon a grant of certification to appeal,
    the respondent, the Commissioner of Correction,
    appeals from the judgment of the habeas court granting
    in part the amended petition for a writ of habeas corpus
    filed by the petitioner, Carvaughn Johnson. The respon-
    dent claims that the court improperly concluded that
    the petitioner proved a violation of his right to a fair
    trial because he did not receive effective assistance
    from his trial counsel. We agree with the respondent
    and, accordingly, reverse in part the judgment of the
    habeas court.
    The following procedural history underlies this
    appeal. Following a jury trial, the petitioner was con-
    victed of murder in violation of General Statutes § 53a-
    54a (a) and carrying a pistol without a permit in viola-
    tion of General Statutes § 29-35. The petitioner was
    sentenced to a total effective term of imprisonment of
    forty-three years. The petitioner brought a direct appeal
    to our Supreme Court, which affirmed the judgment of
    conviction. State v. Johnson, 
    288 Conn. 236
    , 
    951 A.2d 1257
    (2008). Our Supreme Court set forth the facts
    that reasonably could have been found by the jury in
    returning its verdict: ‘‘The [petitioner] shot and killed
    the sixteen year old victim, Markeith Strong, on the
    evening of October 10, 2001, in New Haven. In the weeks
    prior to that evening, the [petitioner] and the victim
    had been at odds with each other. Approximately three
    weeks prior to the shooting, the victim’s teenage sister,
    L’Kaya Ford, was sitting with the victim at the corner
    of Read and Shepard Streets when she observed the
    [petitioner] approach.1 The [petitioner] walked toward
    Ford and the victim, called the victim ‘a punk,’ and
    threatened to assault him. The victim said nothing, and
    the [petitioner] walked away.
    ‘‘The victim next encountered the [petitioner] in the
    late afternoon of September 29, 2001, and the two
    engaged in a dispute over a bicycle. The victim and
    Ralph Ford2 were around the intersection of Read and
    Shepard Streets, where the victim either was riding
    his bicycle or standing near it, when the [petitioner]
    stopped him, declared that the bicycle belonged to him
    and demanded that the victim give it to him. The victim
    refused and informed the [petitioner] that he had found
    the bicycle about one month earlier and had fixed it
    up. The victim told the [petitioner] that he owned the
    bicycle. The [petitioner] asked for the bicycle a second
    time, and, when the victim refused, the [petitioner] said,
    ‘[d]on’t make me do something to you.’ The [petitioner]
    then punched the left side of the victim’s head twice,
    which caused a small cut near the victim’s left ear.
    During this encounter, the [petitioner] may have been
    carrying a gun.3 The [petitioner] then took the bicycle
    and rode away.
    ‘‘After this encounter, the victim, accompanied by
    Ralph Ford, returned home, where his family contacted
    the New Haven police to report the incident. After
    speaking with the victim, the police officers radioed a
    description of the [petitioner] and notice of a possible
    robbery and larceny. The police did not apprehend any
    suspect that day. Over the next few days, the [petitioner]
    approached the victim and L’Kaya Ford about the police
    report, asserted that he was not going to jail, apologized
    to the victim and told him not to press charges. Toward
    the end of September, the [petitioner] also expressed
    concern to his friend, Tashana Milton Toles, about the
    possible criminal charges that he faced as a result of
    the bicycle incident and specifically remarked to her
    that he thought he might be going back to jail.
    ‘‘On the morning of October 10, the [petitioner]
    approached L’Kaya Ford while she was waiting for a
    bus. The [petitioner], who was driving a black car that
    L’Kaya Ford described as an Acura or Ford Probe,
    pulled the car alongside of her and accused her of being
    a snitch. The [petitioner] insulted her, told her he did
    not like snitches and that she knew what happened to
    ‘snitches in the hood.’ That night, the victim, L’Kaya
    Ford, Ralph Ford, and other friends gathered on the
    corner of Read and Shepard Streets to celebrate L’Kaya
    Ford’s birthday. Some of the group, but not Ralph Ford
    or the victim, were drinking alcohol and smoking mari-
    juana. Around 10 p.m., the victim and Ralph Ford
    departed together. The neighborhood around Read,
    Shepard, Huntington and Newhall Streets affords many
    shortcuts through the yards of houses that are occupied
    by neighborhood residents. On that night, however,
    Ralph Ford did not take his usual shortcut but parted
    from the victim, who took the shortcut home. Ralph
    Ford then continued walking alone on Read Street and
    proceeded around the corner to his house on Newhall
    Street.4 Upon arriving at his house, Ralph Ford heard
    a gunshot coming from the backyard of the house across
    the street. Ralph Ford then entered his front hallway.
    Ralph Ford heard someone running from the yard
    across the street and saw the [petitioner] run into the
    driveway leading to Ford’s house.5 Ralph Ford saw the
    [petitioner] carrying a semiautomatic handgun and
    entering a black Acura as it exited the driveway.6 James
    Baker, who lived near the crime scene, heard someone
    run past his window, jump the fence outside his house
    and head into the backyard, toward Huntington Street.
    Approximately five minutes later, and around 10:20
    p.m., Baker heard a single gunshot coming from behind
    his house. LaMont Wilson, who had left the group earlier
    than Ralph Ford and the victim, lived on Read Street
    and also heard a gunshot from the direction of his
    backyard, sometime between 10 and 10:45 p.m. Baker
    called the police at approximately 10:45 p.m. to report
    the gunshot but did not initially identify himself because
    he feared retaliation from ‘certain individuals’ for con-
    tacting the police. Joanie Joyner, a resident of Hunting-
    ton Street and the victim’s next-door neighbor, also
    heard a loud ‘boom’ from the direction of her backyard
    and then, sometime after 11 p.m., saw something in
    her yard. At approximately 11:25 p.m., she also called
    the police.
    ‘‘The [petitioner] contacted Toles by telephone
    between 9:45 and 10 p.m., told her that he was about
    five minutes away from her dormitory at Southern Con-
    necticut State University, and asked if he could visit
    her. Toles agreed. The [petitioner] did not arrive at the
    dormitory until 11 p.m., at which time he phoned Toles
    from the lobby, and she came down to the lobby to
    register him as a visitor at the security desk.7 The [peti-
    tioner] was with a friend, Travis Scott.8 To enter the
    dormitory, the [petitioner] was required to provide iden-
    tification at the security desk where security personnel
    record the information. The sign-in sheet at Toles’ dor-
    mitory indicated that she signed the [petitioner] into
    her building at 11:10 p.m. Shortly after they signed in,
    a fire alarm required all residents and visitors to evacu-
    ate the building. The alarm occurred at approximately
    11:30 p.m., and the fire department and university police
    responded to the scene. The [petitioner] and Scott
    waited with Toles and her roommate until the university
    permitted students to reenter the building. They
    retrieved their identification from the security desk and
    departed. During the investigation, Detective Daryl Bre-
    land of the New Haven police department drove from
    Ralph Ford’s house to Toles’ dormitory, recorded the
    distance to be about three miles and noted that the trip
    took approximately ten minutes.
    ‘‘Officers Mark Taylor and Brian Pazsak of the New
    Haven police department were on patrol in the Newhall
    and Huntington Street area on the night of October 10,
    2001, and received the dispatch related to Baker’s and
    Joyner’s calls. Police responded first to Baker’s call and
    investigated the general area, but saw nothing amiss.
    After responding to Joyner’s call around 11:35 p.m., the
    officers found the victim lying face down in Joyner’s
    backyard. The victim appeared to be unconscious and
    bleeding from the mouth. The officers also found a
    spent nine millimeter shell casing nearby. New Haven
    fire department personnel were called but were unable
    to resuscitate the victim, who was pronounced dead at
    the Hospital of Saint Raphael in New Haven.
    ‘‘Arkady Katsnelson of the chief medical examiner’s
    office performed an autopsy of the victim on October
    11, 2001, and determined that he had died of a single
    gunshot wound to the right side of his face.9 Katsnelson
    concluded that the bullet penetrated the victim’s face
    and neck, and completely severed the spinal cord,
    instantly incapacitating the victim.’’ (Footnotes in origi-
    nal.) 
    Id., 239–43. Thereafter,
    the petitioner brought an amended peti-
    tion for a writ of habeas corpus in which he raised two
    types of claims. In the first count of his petition, the
    petitioner alleged that his right to conflict free trial
    counsel had been violated because his trial counsel,
    Scott Jones and Beth Merkin, had an actual conflict of
    interest that adversely affected their performance. In
    the second count of his petition, the petitioner alleged
    a violation of his right to the effective assistance of
    counsel. The second count involved trial counsel’s fail-
    ure to present (1) a third party culpability defense and
    (2) an alibi defense that explained his whereabouts at
    the time of the shooting. With respect to the third party
    culpability defense, the petitioner alleged that his trial
    counsel had ‘‘failed to adequately cross-examine Ralph
    Ford about . . . his possession of a pistol that was
    consistent with the pistol that discharged the bullet that
    killed the victim in the days before the shooting; and
    . . . about his prior statement that he did not see any-
    thing on the night of the shooting, and that he felt
    pressure from the police, the victim’s family, and his
    family to implicate the petitioner in the shooting . . . .’’
    Also, the petitioner alleged that his trial counsel had
    ‘‘failed to present the testimony of William Holly about
    Ralph Ford’s possession of a pistol that was consistent
    with the pistol that discharged the bullet that killed the
    victim in the days before the shooting . . . [and] they
    failed to present the testimony of . . . Matthew
    Whalen [an investigator for the public defender’s office]
    about William Holly’s statement that he saw Ralph Ford
    in possession of a pistol that was consistent with the
    pistol that discharged the bullet that killed the victim
    in the days before the shooting . . . .’’10 With respect
    to the alibi defense, the petitioner alleged that his trial
    counsel had ‘‘failed to present the testimony of Joyce
    Johnson, the petitioner’s sister, about the petitioner’s
    presence at their home at the time of the shooting; and
    . . . they failed to present the testimony of Taylor Allen
    about the petitioner’s presence at his home at the time
    of the shooting.’’
    The respondent denied that the petitioner’s right to
    conflict free representation had been violated or that
    he had been denied his right to effective representation
    at trial. Additionally, the respondent raised the special
    defense of procedural default with respect to both
    counts of the petition for a writ of habeas corpus. In
    a reply to the respondent’s return, the petitioner denied
    the special defense.
    Over the course of five days, the habeas court held
    an evidentiary hearing with respect to the claims set
    forth in the petition. In addition to other evidence, the
    petitioner presented testimony from Jones; Merkin;
    Holly; Thomas Farver, former counsel for Holly;
    Whalen; Johnson; Allen; Gerard Petillo, a firearms
    examiner and shooting incident reconstruction consul-
    tant; and Thomas Ullmann, public defender for the New
    Haven judicial district who supervised Jones and Mer-
    kin in their trial representation of the petitioner. The
    respondent presented testimony from Marc Caporale
    and Breland, former detectives with the New Haven
    Police Department who had been involved in the investi-
    gation into the victim’s death. At a separate, subsequent
    hearing, the court heard lengthy closing arguments,
    which was followed by the parties’ submission of post-
    trial briefs.
    In a thorough memorandum of decision, the habeas
    court ruled in favor of the respondent with respect
    to the conflict of interest claim. With respect to the
    ineffective assistance claim, the court determined that
    the petitioner’s right to the effective representation of
    counsel had been violated by counsel’s failure to pre-
    sent a third party culpability claim and by counsel’s
    failure to present an alibi defense.
    The habeas court set forth the following findings of
    fact: ‘‘In the petitioner’s first criminal trial, the court
    declared a mistrial due to a hung jury. The state pre-
    sented testimony at the first criminal trial from an eye-
    witness, Ralph Ford, who testified consistent with his
    statements to the police that he heard a gunshot and
    saw the petitioner run out of the backyard across the
    street carrying a black gun in his hand. At the first
    trial, trial counsel presented a partial alibi defense with
    testimony indicating that the petitioner was at Southern
    Connecticut State University around 11 p.m. on the
    night of the murder. [The defense] did not explain the
    petitioner’s whereabouts between 10 and 11 p.m. After
    the first trial resulted in a hung jury, a juror indicated
    that it would have been helpful for the jury to know
    where the petitioner was at the time of the shooting
    [which occurred] prior to 11 p.m.
    ‘‘At the petitioner’s second criminal trial, the state’s
    key witness, Ford, recanted his prior statement and
    testimony that he had seen the petitioner running from
    the crime scene with a gun. Instead, Ford testified that
    the police forced him to make those statements. Ford’s
    prior inconsistent statements at the first criminal trial
    were admitted for substantive purposes in the second
    criminal trial pursuant to [the doctrine set forth in State
    v. Whelan, 
    200 Conn. 743
    , 753, 
    513 A.2d 86
    , cert. denied,
    
    479 U.S. 994
    , 
    107 S. Ct. 597
    , 
    93 L. Ed. 2d 598
    (1986)].
    ‘‘At the second trial, trial counsel’s defense strategy
    was that the state failed to prove the petitioner’s guilt
    beyond a reasonable doubt, that Ford was not credible,
    and that it was Ford that had accidentally shot the
    victim, who was Ford’s friend. The petitioner’s trial
    attorneys disagreed over whether to present an alibi,
    including the petitioner’s whereabouts between 10 and
    11 p.m. or a third party culpability defense; Attorney
    Jones wanted to present both defenses and Attorney
    Merkin did not. Attorney Merkin prevailed and trial
    counsel did not present either defense at the second
    trial.’’ (Footnote omitted.)
    In addressing the aspect of the petitioner’s ineffective
    assistance of counsel claim that involved the failure of
    his trial counsel to present evidence in support of a
    third party culpability defense, the court set forth rele-
    vant legal principles and stated in relevant part: ‘‘The
    petitioner claims that trial counsel were ineffective for
    failing to call Holly or Inspector Whalen as witnesses
    to support the theory that Ford accidentally committed
    the murder, or investigate whether Holly could identify
    a photograph of the pistol as being the weapon he saw
    Ford in possession of [on] the day of the shooting. . . .
    ‘‘At the second criminal trial, the state established
    that the bullet recovered from the victim was from a
    Hi-Point nine millimeter pistol or semiautomatic rifle.
    At the habeas trial, the petitioner established that Ford
    showed Holly a black handgun that Ford had tucked
    into the waistband of his pants on the afternoon of the
    shooting. Holly believed that a photograph of the Hi-
    Point nine millimeter pistol used in the shooting looked
    like the gun that he saw Ford carrying. The murder
    weapon and Ford’s gun both had ridges above the han-
    dle, and ridges were not a common feature on the guns
    that Holly had seen.
    ‘‘The petitioner’s trial attorneys disagreed as to
    whether the third party culpability defense should be
    presented to the jury. Attorney Jones believed that Hol-
    ly’s testimony should have been presented and Attorney
    Merkin did not, even though she admitted that Holly’s
    testimony was consistent with the defense theory of
    the case, which was that Ford accidentally shot the
    victim. The court finds the third party culpability
    defense consisting of the facts that (1) Ford had been
    the last person seen with the victim, (2) was in close
    proximity to the location of the shooting at the time of
    the shooting, and (3) had been seen with a gun matching
    the description of the murder weapon on the day of
    the shooting, were consistent with and relevant to the
    defense theory that it was Ford who shot the victim
    by accident.
    ‘‘Both Attorney Jones and Attorney Merkin thought
    that they would not be able to present Holly’s testimony
    without Ford first admitting that he knew Holly. Trial
    counsel believed, incorrectly, that they needed, and did
    not have, a foundation to introduce third party culpabil-
    ity evidence—that is, the testimony of Holly—once
    Ralph Ford denied knowing Holly while on the witness
    stand at the petitioner’s criminal trial. At the habeas
    trial, Attorney Merkin conceded that the presentation
    of Holly’s testimony was not contingent upon Ford
    admitting that he knew Holly. The issue with presenting
    testimony supporting a third party culpability defense
    is not about presenting a foundation for admitting the
    evidence; it is about the petitioner’s constitutional right
    to present a defense and relevant evidence in support
    of that defense. . . .
    ‘‘[T]he standard for determining whether evidence
    of third party culpability is admissible is whether the
    presented evidence is relevant. Here, it was. Holly’s
    testimony regarding Ford’s possession of the same type
    of gun that was used to kill the victim on the day of
    the shooting, as well as other facts pointing to Ford
    as the shooter, would have established the necessary
    factual nexus for a third party culpability claim regard-
    less of whether Ford knew Holly. The court finds it
    reasonably likely that the trial court would have allowed
    Holly’s testimony.
    ‘‘The [respondent] argues that Attorney Farver com-
    municated to the court on Holly’s behalf that Holly
    would assert his fifth amendment privilege and refuse
    to testify if he was called [as a witness]. However, both
    Attorney Farver and Attorney Merkin testified that they
    were uncertain that Holly would have been permitted to
    invoke his fifth amendment privilege at the petitioner’s
    criminal trial due to the fact that Holly’s pending
    charges were unrelated to the petitioner’s case. At the
    criminal trial, Farver reported to the court: ‘I met with
    Mr. Holly this morning and discussed with him his rights
    and whether to testify or not to testify if called upon
    to do so. I explained to him, if he, well, first of all, let
    me say that he does not wish to testify. It is his position
    at this point as he expressed to me that he, first of
    all, would exercise a fifth amendment right, although
    I candidly don’t know how far the testimony or the
    inquiry would be going [or] whether he has such a right.
    Quite honestly, I know that he has pending charges of
    his own here in the courthouse. I don’t believe those
    are related to this case. However, he would first of all
    have to assert a fifth amendment right. The court may
    choose to find that he does not have a fifth amendment
    right as to this particular information that is being
    sought. If the court were to rule in that fashion and
    order him to testify, I have explained to him that he
    could be found in contempt of court if he continues to
    decline to testify; he has indicated to me that his posi-
    tion would still be that he would refuse to testify
    because he has pending charges and he does not want
    to testify.’ . . .
    ‘‘In the present case, Holly’s pending charges were
    unrelated to the petitioner’s case, and there is no indica-
    tion that Holly’s testimony that he saw Ford with a gun
    on the day of the shooting would have exposed him to
    any criminal prosecution in the petitioner’s or any other
    case. Fear of potential prosecutorial retaliation in an
    unrelated case does not constitute sufficient grounds
    to invoke the fifth amendment, as it is a mere subjective
    belief, not a reality, and the actual testimony would
    not have been incriminating in any way. Therefore, the
    court finds that it is not reasonably likely that Holly
    would have been permitted to invoke his privilege
    against self-incrimination in the petitioner’s criminal
    case had trial counsel proffered him as a defense wit-
    ness to support the third party culpability defense. . . .
    ‘‘In the present case, the court finds that trial counsel
    was deficient for not pursuing the petitioner’s third
    party culpability defense because it was supported by
    a neutral, credible witness, and the evidence was rele-
    vant to the central issue of whether a reasonable doubt
    existed as to whether the petitioner committed the
    crime. . . . [I]n light of all of the circumstances here,
    particularly the recanted testimony of Ford, whose tes-
    timony served as the state’s primary evidence, and the
    facts pointing to Ford’s culpability, trial counsel’s fail-
    ure to . . . present the third party culpability defense
    fell below an objective standard of reasonableness, and
    therefore constitutes deficient performance pursuant
    to [Strickland v. Washington, 
    466 U.S. 668
    , 687, 104 S.
    Ct. 2052, 
    80 L. Ed. 2d 674
    (1984)].
    ‘‘The court also further finds that trial counsel’s fail-
    ure to present the third party culpability defense preju-
    diced the petitioner because there is a reasonable
    probability that the outcome of the proceedings would
    have been different had the defense been presented to
    the jury. As a result, the court finds that the petitioner
    has satisfied the prejudice prong of Strickland as to
    this claim.’’ (Citations omitted.)
    In addressing the aspect of the petitioner’s ineffective
    assistance of counsel claim that involved the failure of
    his trial counsel to present evidence in support of an
    alibi defense that involved the testimony of Johnson
    and Allen to explain his whereabouts at the time of the
    shooting, the court set forth relevant legal principles
    and stated in relevant part: ‘‘The petitioner claims that
    trial counsel were ineffective for failing to call Johnson
    and Allen as witnesses to testify that he was home at
    the time of the shooting in support of an alibi defense.
    The court agrees with the petitioner on this claim. . . .
    ‘‘The petitioner’s trial counsel [was] aware of the two
    alibi witnesses, Allen and Johnson, who could testify
    as to [the] petitioner’s whereabouts between 10 and 11
    p.m. on the evening of the shooting, but disagreed as
    to whether an alibi defense should be presented. They
    were also aware that the jury in the first trial wanted
    to know where the petitioner was between 10 to 11
    p.m. Attorney Jones wanted to present the alibi defense
    because he believed the witnesses were credible and
    their testimony explained the petitioner’s whereabouts
    at the time of the shooting in response to the first jury’s
    concerns as to where the petitioner was between 10
    and 11 p.m. Attorney Merkin does not like alibi defenses
    generally, and her practice was not to present an alibi
    defense unless it was rock solid. Attorney Jones con-
    ceded to Attorney Merkin’s decision to not present the
    alibi defense because she was more senior to him.
    ‘‘At the second criminal trial, James Baker, a Read
    Street resident, testified that at 10:20 p.m., he heard a
    gunshot. Baker did not call the police until 10:45 p.m.
    Prior to the petitioner’s first criminal trial, Attorney
    Merkin had inaccurate information about the time of
    the shooting. She mistakenly believed that the shooting
    occurred at 10:45 p.m. Counsel’s notice of alibi, dated
    July 29, 2003, inaccurately reported that Baker called
    the police at 10:45 p.m., immediately after the shooting
    occurred. It was only when Baker testified at the peti-
    tioner’s first criminal trial that counsel became aware
    that the correct time of the shooting was 10:20 p.m.
    ‘‘Johnson and Allen testified credibly at the habeas
    trial as to the petitioner’s whereabouts on the night of
    the shooting. Johnson testified that the petitioner was
    home between 5 and 11 p.m. on the night of the shooting.
    During that time, Johnson was home with her young
    son and was for the most part in the living room in the
    front of the apartment watching television. From her
    position, she would have been able to see if the peti-
    tioner had left the house during that time. At some
    point, Johnson was aware that the petitioner and his
    friend were at the house and ordered a pizza. The living
    room had two large windows facing the driveway, and
    any movement outside would have activated the motion
    sensor lights in the driveway. If the petitioner had left
    through the back door, Johnson would have heard him
    because that door screeched loudly when [it was]
    opened. At approximately 11 p.m., Johnson heard a
    horn honk outside, and she saw the petitioner leave
    the house with Allen.
    ‘‘Allen, who also testified at the habeas trial credibly,
    called the petitioner’s cell phone at 10:20 p.m., and he
    asked her to call his home telephone number. Allen
    immediately hung up and called the petitioner at home
    on his landline. Allen and the petitioner spoke for
    approximately ten to fifteen minutes on the petitioner’s
    home phone. The petitioner then called Allen again from
    his home telephone around 10:40 p.m. or 10:45 p.m.
    Shortly thereafter, Allen drove to the petitioner’s home,
    picked him up at approximately 10:50 p.m. or 10:55 p.m.
    and drove him to Southern Connecticut State Univer-
    sity.11 The court finds that the testimony of Allen and
    Johnson would have been helpful to the petitioner’s
    defense.
    ‘‘Inspector Whalen testified that he interviewed Allen
    and Johnson. Johnson informed him that the petitioner
    was at home with a friend on the night of the shooting
    and someone picked the petitioner up between 10:45
    p.m. and 11 p.m. Allen told Inspector Whalen that she
    called the petitioner at his home at 10:20 p.m., and she
    picked the petitioner up around 10:35 p.m. or 10:40 p.m.
    to drive him to Southern Connecticut State University.
    At the time of his interview with Allen, Inspector
    Whalen was aware of the fact that the victim was shot
    at 10:20 p.m. Inspector Whalen reported the information
    he received from Johnson and Allen to the petitioner’s
    trial counsel.
    ‘‘Trial counsel also had the partial alibi presented at
    the first criminal trial of Toles, who testified that the
    petitioner arrived at the Southern Connecticut State
    University to visit her at approximately 11:10 p.m. on
    the night of the shooting.
    ‘‘The court finds that trial counsel was aware of the
    statements of Johnson and Allen, that their testimony
    was credible and that production of such testimony at
    trial would have been helpful to the defense. . . .
    ‘‘[H]ere, trial counsel’s decision to not call the alibi
    witnesses was not based on the witnesses’ credibility.
    Both Attorney Jones and Attorney Merkin found John-
    son and Allen to be credible witnesses. Moreover, the
    court finds that their testimony would have been helpful
    to the petitioner’s defense that he was home at the time
    of the shooting.
    ‘‘Attorney Merkin decided to not present Johnson’s
    testimony because she was related to the petitioner, the
    shooting occurred in close proximity to the petitioner’s
    home and it was unclear whether the petitioner was in
    her direct vision for the entire evening. Attorney Merkin
    did not present Allen’s testimony because she believed
    that Allen estimated the times of the phone calls, and
    the petitioner’s close proximity to the crime scene
    would have allowed him to commit the murder despite
    receiving and making the phone calls at the times indi-
    cated by Allen. Trial counsel acknowledged at the
    habeas trial, however, that they failed to investigate
    Johnson’s ability to provide an alibi at the times when
    the petitioner was not in her direct view. Johnson testi-
    fied that the motion sensor lights and the screeching
    back door would have prevented the petitioner from
    leaving the house without Johnson’s knowledge. More-
    over, the times of the phone calls between Allen and
    the petitioner were seen on Allen’s caller identification.
    That evidence, if presented, would have established
    that the petitioner was at home using his landline at
    the time the shooting occurred. Further, while Attorney
    Merkin was concerned that the alibi defense would
    place the petitioner in close proximity to the crime
    scene, there was already evidence before the jury that
    the petitioner was at Southern Connecticut State Uni-
    versity, close to the crime scene, shortly before 11 p.m.
    on the night of the victim’s murder. In addition, the
    evidence from the three alibi witnesses covered the
    time period between 10 and 11 p.m., making it highly
    unlikely that the petitioner could have committed the
    shooting.
    ‘‘The court is particularly influenced by the fact that
    when trial counsel decided not to submit the petitioner’s
    alibi, they were aware that the first jury was conflicted
    about the petitioner’s guilt, which resulted in a hung
    jury, and [counsel] knew that the first jury wanted to
    know where the petitioner was at the time the shooting
    occurred. While each jury is different, having this infor-
    mation in the petitioner’s second criminal trial was a
    significant bonus to the defense and should have been
    utilized in determining whether to pursue the alibi
    defense.
    ‘‘Pursuant to the foregoing, the court finds that in
    light of the circumstances in this case, and the credible
    evidence presented, it was not objectively reasonable
    for trial counsel to not present the alibi witnesses. The
    court had the opportunity to hear and to evaluate the
    two witnesses, and found their testimony to be credible
    and compelling and [that the testimony] would have
    been helpful to the petitioner’s case. . . . Trial counsel
    also found the alibi witnesses to be credible, and that
    their testimony would have been helpful to the petition-
    er’s defense. Accordingly, the court concludes that the
    petitioner has met his burden to prove that counsel’s
    conduct was constitutionally deficient under the perfor-
    mance prong of Strickland.
    ‘‘The court also finds that trial counsel’s failure to
    call the alibi witnesses prejudiced the petitioner
    because there is a reasonable probability that the out-
    come of the proceedings would have been different had
    it not been for the deficient performance. The court
    finds that the testimony from Johnson and Allen likely
    would have affected the verdict, especially in light of
    the weakness of the state’s case and the fact that the
    jurors at the first criminal trial that resulted in a hung
    jury were interested in where the petitioner was at the
    time of the shooting. As a result, the court finds that
    the petitioner has satisfied the prejudice prong of
    Strickland as to this claim.’’ (Citations omitted; foot-
    note added.)
    The court denied the petition with respect to the
    conflict of interest claim, and granted the petition with
    respect to the ineffective assistance of counsel claim.
    The court vacated the judgment of conviction and
    returned the case to the trial court for further proceed-
    ings. Later, the court granted the respondent’s petition
    for certification to appeal, and this appeal by the respon-
    dent followed.
    The habeas court’s memorandum of decision reflects
    that it considered and analyzed separately each of the
    two grounds alleged in the petitioner’s claim in which
    he alleged that he had received ineffective assistance
    from his trial counsel. The court determined that the
    petitioner had satisfied his burden under Strickland
    with respect to his claim that counsel had failed to
    present certain evidence in support of a third party
    culpability defense and with respect to his claim that
    counsel had failed to present an alibi defense that
    explained his whereabouts at the time of the shooting.
    Because the habeas court’s judgment rests upon either
    of these grounds, it is the respondent’s burden on appeal
    to demonstrate that the habeas court erroneously ruled
    as it did with respect to both grounds.
    ‘‘When reviewing the decision of a habeas court, the
    facts found by the habeas court may not be disturbed
    unless the findings were clearly erroneous. . . . The
    issue, however, of [w]hether the representation [that]
    a defendant received at trial was constitutionally inade-
    quate is a mixed question of law and fact. . . . As such,
    that question requires plenary review by [a reviewing
    court] unfettered by the clearly erroneous standard.
    . . .
    ‘‘A criminal defendant is constitutionally entitled to
    adequate and effective assistance of counsel at all criti-
    cal stages of criminal proceedings. . . . This right
    arises under the sixth and fourteenth amendments to
    the United States constitution and article first, § 8, of
    the Connecticut constitution. . . . It is axiomatic that
    the right to counsel is the right to the effective assis-
    tance of counsel. . . .
    ‘‘As enunciated in Strickland v. Washington, [supra,
    
    466 U.S. 687
    ] . . . [a] claim of ineffective assistance of
    counsel consists of two components: a performance
    prong and a prejudice prong. To satisfy the performance
    prong . . . the petitioner must demonstrate that his
    attorney’s representation was not reasonably compe-
    tent or within the range of competence displayed by
    lawyers with ordinary training and skill in the criminal
    law. . . . To satisfy the prejudice prong, a claimant
    must demonstrate that there is a reasonable probability
    that, but for counsel’s unprofessional errors, the result
    of the proceeding would have been different. . . . A
    court can find against a petitioner, with respect to a
    claim of ineffective assistance of counsel, on either
    the performance prong or the prejudice prong . . . .’’

    Michael T. v. Commissioner of Correction, 
    319 Conn. 623
    , 631–32, 
    126 A.3d 558
    (2015).
    I
    First, we consider the respondent’s claim that the
    habeas court erroneously concluded that the petitioner
    was deprived of his right to effective assistance of coun-
    sel by his counsel’s failure to present testimony from
    Holly in support of a third party culpability defense. As
    discussed previously in this opinion, this evidence is
    centered on the testimony of Holly. We agree with
    the respondent.
    The respondent challenges the court’s decision with
    respect to the third party culpability defense on several
    grounds. With regard to the court’s evaluation of the
    performance of trial counsel, the respondent argues
    that it did not afford adequate consideration to the
    evidence that defense counsel’s failure to present Hol-
    ly’s testimony in support of the third party culpability
    defense was the result of reasonable trial strategy rather
    than deficient representation. In this respect, the
    respondent focuses on evidence presented at the
    habeas trial that supported a finding that defense coun-
    sel, in crafting a sound trial strategy, did not want to
    divert the jury’s attention from the weaknesses in the
    state’s case, particularly, the significance of Ford’s
    recantation. With respect to the prejudice prong of
    Strickland, the respondent argues: ‘‘[I]n evaluating prej-
    udice from the defense team’s decision not to call Holly
    to the [witness] stand at the criminal trial, the habeas
    court erred in concluding that the petitioner met his
    burden of establishing that Holly’s testimony carried
    no possibility of self-incrimination and that, therefore,
    Holly’s fifth amendment privilege would not have been
    an impediment to his testimony.’’ The respondent
    argues that the court erroneously concluded that there
    was a reasonable likelihood that the outcome of the
    trial would have been different if the evidence at issue
    had been presented by the defense.
    Assuming but not deciding that defense counsel’s
    failure to attempt to present evidence from Holly in
    support of a third party culpability defense was the
    result of representation that was not reasonably compe-
    tent, we nonetheless conclude, under the prejudice
    prong of Strickland, that the petitioner failed to demon-
    strate that there is a reasonable probability that, but
    for counsel’s alleged errors, the result of the proceeding
    would have been different.
    We turn to the findings of the habeas court as well
    as some of the pertinent evidence that was not in dis-
    pute. The habeas court found, and the record reflects,
    that when the issue of Holly’s testimony was first raised
    at the time of the criminal trial at a posttrial hearing on
    the petitioner’s motion for a new trial, Holly’s counsel,
    Farver, communicated to the court that Holly did not
    wish to testify, that he intended to exercise his fifth
    amendment right to remain silent and that, even if the
    court ordered him to testify, he would decline to do
    so. Farver communicated to the court that his client’s
    position was based upon the fact that he had criminal
    charges pending against him.
    At the habeas trial, Holly testified that at the time of
    the petitioner’s trial, he was incarcerated in Connecticut
    and had a case pending in the New Haven courthouse,
    in which proceeding he was represented by Ullmann.
    Holly testified that with respect to his testifying at the
    petitioner’s criminal trial, Ullmann and Farver had
    advised him to invoke his right to remain silent. Holly
    testified that, later, Farver was appointed to represent
    him in connection with his potential involvement in the
    petitioner’s trial. Holly testified that he communicated
    to Ullmann and Farver that he would not testify. He
    testified, however, that, if he had been ordered to do
    so, he would have testified consistent with the testi-
    mony that he provided before the habeas court in the
    present case because, if a court determined that he
    could not invoke his right to remain silent, he would
    not have had a choice in the matter. Holly explained
    that one of the reasons why he did not want to testify
    was because he feared that the prosecutor, who was
    involved in the petitioner’s trial and in a then pending
    investigation of Holly for the crime of murder, would
    retaliate against him. He stated, however, that he did
    not believe that his testimony in the petitioner’s case
    would incriminate him.
    At the habeas trial, Ullmann testified that he repre-
    sented Holly between 2002 and 2005, the time period
    which encompassed the petitioner’s second criminal
    trial. He testified that he represented Holly with respect
    to a variety of charges that, following a plea negotiation,
    resulted in a conviction of robbery in the first degree
    and assault on a peace officer. Also, he testified that,
    at times relevant, he was representing Holly with
    respect to ‘‘some other [legal] issues,’’ as well. Ullmann
    testified that he became aware that Holly had informa-
    tion that might be relevant to the petitioner’s case and
    that members of the petitioner’s defense team wanted
    to speak with Holly, at which time Ullmann informed
    Whalen that he was representing Holly in relation to a
    pending murder investigation and that he had advised
    Holly not to speak with him. Ullmann testified that he
    understood the information to involve Holly’s observa-
    tion of a potential killer who was armed.
    Ullmann testified that, later, he arranged for Farver to
    represent Holly solely with respect to Holly’s potential
    involvement in the petitioner’s trial, but that he contin-
    ued to represent Holly with respect to his pending
    charges as well as the murder investigation. With
    respect to his concern about Holly’s cooperation with
    the petitioner’s defense and the importance of providing
    the petitioner with representation concerning that
    issue, he stated: ‘‘I’m obviously representing somebody
    who’s facing serious criminal charges, who’s being
    investigated for something else, and I’m [given] this
    information about [the desire of the petitioner’s trial
    attorneys] to put him on the [witness] stand in relation
    to some gun. I’m not letting them talk to him.’’ Ullmann
    continued, ‘‘there’s the potential that William Holly
    could incriminate himself or hurt his situation in the
    pending case that . . . I was representing him on.’’
    Additionally, Ullmann explained that he was motivated
    by a concern that Holly’s cooperation with the defense
    or his testimony in the petitioner’s case could subject
    him to retaliation by the prosecutor with respect to his
    ‘‘very serious’’ pending criminal matters.
    At the habeas trial, Farver testified that, during con-
    versations with Holly concerning his involvement in the
    petitioner’s trial, Holly unequivocally stated to him that
    he intended to invoke his right to remain silent and
    that, even if he were ordered to testify, he would decline
    to do so. Farver testified that he was unsure whether,
    at the time that he represented Holly, he was awaiting
    sentencing on charges to which he had pleaded guilty.
    Moreover, he believed that, at that time, Holly was being
    investigated for murder. Farver recalled that this mur-
    der investigation was related to the fact that Holly ‘‘had
    given a statement possibly [as a] primary or aiding and
    abetting a conspiracy that he was in a car, not the
    shooter, but he was busted with the gun.’’ Farver testi-
    fied that he did not form an opinion with respect to
    whether Holly could avail himself of his fifth amend-
    ment privilege in the petitioner’s case.
    In its findings, the habeas court did not discuss the
    significance of Farver’s testimony, which was consis-
    tent with his representations at the time of the petition-
    er’s second criminal trial, that Holly had represented
    to him that he would not testify even if he was ordered
    to do so. The habeas court, implicitly accepted as true
    Holly’s testimony that he would have testified at the
    petitioner’s trial if the court had rejected his invocation
    of his fifth amendment privilege, and resolved the fifth
    amendment issue by concluding that ‘‘there is no indica-
    tion that Holly’s testimony that he saw Ford with a gun
    on the day of the shooting would have exposed him to
    any criminal prosecution in the petitioner’s [case] or
    any other case.’’ The court also reasoned that Holly’s
    fear of prosecutorial retaliation was not a valid ground
    upon which to invoke the fifth amendment privilege.
    The evidence amply supported the court’s finding
    that Holly had manifested his intention of invoking his
    fifth amendment right to remain silent if he was called
    as a witness at the petitioner’s trial. The relevant legal
    principles related to the invocation of that right are
    well settled in our case law. ‘‘A court may not deny a
    witness’ invocation of the fifth amendment privilege
    against compelled self-incrimination unless it is per-
    fectly clear, from a careful consideration of all the cir-
    cumstances in the case, that the witness is mistaken,
    and that the answer[s] cannot possibly have [a] ten-
    dency to incriminate. . . . To sustain the privilege, it
    need only be evident from the implications of the ques-
    tion, in the setting in which it is asked, that a responsive
    answer to the question or an explanation of why it
    cannot be answered might be dangerous because injuri-
    ous disclosure could result. . . . In appraising a fifth
    amendment claim by a witness, a judge must be gov-
    erned as much by his personal perception of the peculi-
    arities of the case as by the facts actually in
    evidence. . . .
    ‘‘[T]he right to one’s privilege against prosecution
    that could result from the testimony sought does not
    depend upon the likelihood of prosecution but upon
    the possibility of prosecution. . . . [T]he trial court
    [is] obligated to assess only whether a possibility of
    future prosecution [exists], or could arise, by virtue
    of the proffered testimony in light of existing law.’’

    The respondent argues, and we agree, that the record
    before the habeas court precluded a careful consider-
    ation of all of the circumstances surrounding Holly’s
    invocation of his fifth amendment privilege. Under
    Strickland, it was the petitioner’s burden to prove that
    he was prejudiced by the deficient performance of his
    trial counsel. In the context of the present claim, that
    burden necessarily entailed demonstrating that Holly
    would have been unable to assert a fifth amendment
    privilege with respect to questions concerning his
    observations of Ford on the day of the shooting. Yet,
    the record presented before the habeas court does not
    reveal many details surrounding the serious legal mat-
    ters that he faced at the time of the petitioner’s second
    criminal trial. These matters included the robbery in
    the first degree and assault of a police officer charges
    to which he had pleaded guilty, as well as a pending
    investigation for murder.
    Moreover, despite the scant information available to
    the trial court, the undisputed evidence concerning Hol-
    ly’s circumstances that was presented to the habeas
    court supported a conclusion that Holly’s testimony
    about his interaction with Ford possibly incriminated
    Holly in criminal activity, regardless of whether such
    criminal activity was related directly to the petitioner’s
    case or the incident at issue therein. As set forth pre-
    viously, there was evidence that, at times relevant, Holly
    was the subject of an investigation for a murder that
    involved the use of a gun. The evidence suggested that
    he had pleaded guilty to charges of robbery in the first
    degree and assault of a police officer, but that the pro-
    ceedings related to such charges had not concluded.
    At the habeas trial, the petitioner relied on Holly’s
    testimony to demonstrate that he was prejudiced by
    trial counsel’s failure to present such testimony at his
    criminal trial. In his posttrial brief before the habeas
    court, the petitioner drew the attention of the habeas
    court to Holly’s interaction with Ford, his observations
    of the gun in Ford’s possession, and his attempt to gain
    possession of the gun. Following his direct examination
    at the habeas trial, the petitioner’s counsel asked Holly:
    ‘‘If you had testified, been brought to court and been
    ordered by the court to testify, would you have testified
    in the same manner then as you did today?’’ Holly
    replied, ‘‘Yes.’’
    A review of Holly’s testimony at the habeas trial
    readily reveals that he was asked questions that not
    merely called for him to describe his observations of
    and interaction with Ford on the day of the victim’s
    murder, but that called for him to explain his familiarity
    with guns. Holly’s examination at the habeas trial
    reveals the type of inquiry that he would have been
    subjected to at the petitioner’s criminal trial and, thus,
    sheds light on the issue before us. At the habeas trial,
    Holly testified in relevant part that he observed Ford
    and the victim on the day of the shooting, when he was
    either sixteen or seventeen years of age. During his
    direct examination, the following colloquy occurred
    between Holly and the petitioner’s counsel:
    ‘‘Q. . . . Did [Ford] show you a weapon?
    ‘‘A. Yes. I tried to take it from him.
    ‘‘Q. What kind of a weapon did he show you?
    ‘‘A. It was, like, an all black .380 or a nine millimeter.
    ‘‘Q. Was it a pistol?
    ‘‘A. Yes.
    ‘‘Q. Was it a handgun?
    ‘‘A. A handgun.
    ‘‘Q. And you said it was either a nine millimeter or
    a .380?
    ‘‘A. Yes.
    ‘‘Q. And then what did you do when they showed or
    when Ralph Ford showed it to you?
    ‘‘A. I asked to see it, for them to put it in my hand.
    And then he took off running.’’
    Thereafter, the petitioner’s counsel showed Holly a
    photograph of a gun and asked him to compare it with
    the one that he had observed in Ford’s possession. Holly
    testified that the gun depicted in the photograph was
    similar to the one that Ford had showed him that day.
    During cross-examination, the respondent’s counsel
    asked Holly why he remembered his encounter with
    Ford. Holly replied that he remembered seeing Ford
    and the victim ‘‘because I tried to get the gun from
    them. I wanted that gun.’’ Holly testified during cross-
    examination that Ford had showed him the gun, which
    was tucked into his waistband, by lifting his shirt. Holly
    stated that he told Ford to put the gun in his hand. He
    testified that he ‘‘tried to grab’’ Ford, who pulled away
    from him. When the respondent’s counsel asked Holly
    about the appearance of the gun, Holly stated: ‘‘I know
    guns. Yes, it was black. . . . I’d seen the clip of the
    gun. That’s how I knew it was either a .380 or a nine
    millimeter.’’ (Emphasis added.) When asked whether
    he had seen other young men in the Newhallville neigh-
    borhood with guns, Holly went on to testify: ‘‘If you were
    in the streets, you’re going to see people with guns.’’
    During redirect examination, Holly was asked once
    again to compare a photograph of a gun with the gun
    he had observed. Holly stated: ‘‘The gun Ralph Ford
    showed me looked like one of the guns I had before.
    That’s why I thought it was real. That’s why I tried to
    take it.’’ When asked during further examination by the
    respondent’s counsel about the characteristics of the
    gun in the photograph, Holly testified that he had seen
    similar guns, and that one of the characteristics of the
    gun in the photograph was uncommon. Specifically,
    Holly testified that he observed ridges on the top of the
    gun in Ford’s possession, above the handle, which he
    considered to be an uncommon feature of the guns that
    he had seen.
    At the habeas trial, the petitioner did not attempt to
    demonstrate that, if Holly had invoked his fifth amend-
    ment privilege at the time of the criminal trial, his testi-
    mony at the criminal trial would have been different
    from his testimony at the habeas trial. The petitioner,
    who bore the burden of proving deficient performance
    and prejudice in connection with trial counsel’s failure
    to present Holly’s testimony, appears to have relied on
    the entirety of Holly’s testimony at the habeas trial
    to sustain his burden of proof. Thus, Holly’s habeas
    testimony was presented as the type of inquiry to which
    Holly would have been subjected at the petitioner’s
    trial. On the basis of that inquiry, as well as the evidence
    of the criminal issues that Holly faced at the time of
    the trial, it is reasonable to conclude that Holly would
    have been asked to provide answers that possibly would
    have furnished a link in the chain of evidence needed
    to prosecute him for one or more crimes.
    The inquiries at issue called upon Holly to describe
    the basis of his ability to accurately characterize the
    gun in Ford’s possession. In doing so at the habeas trial,
    Holly revealed that he wanted to gain possession of the
    gun on the day of the shooting, he attempted forcibly
    to gain possession of the gun on the day of the shooting,
    he was very familiar with guns, and he had possessed
    one or more guns prior to the day of the shooting.
    Against this evidentiary background, Ullmann’s belief,
    that any inquiry about guns directed at Holly posed a
    danger to his penal interests, was eminently supported
    by the questions and answers that comprised Holly’s
    examination at the habeas trial. Moreover, as Ullmann
    expressed, concerns that Holly’s testimony possibly
    would have exposed him to criminal prosecution were
    magnified in the present case in light of the fact that
    he was already the subject of criminal prosecution in
    the New Haven judicial district by the same prosecutor
    that was prosecuting the charges against the petitioner.
    Although it appears that the habeas court thoroughly
    considered the evidence before it, it also appears from
    the analysis set forth in the court’s memorandum of
    decision that the court took a narrow view of the fifth
    amendment issue, considering only whether Holly’s
    direct observations of Ford likely would have subjected
    him to criminal prosecution, rather than whether it was
    possible that any questions asked of Holly during his
    direct or cross-examination could possibly have incrim-
    inated him in any other criminal prosecution. In light
    of the foregoing, we conclude that the court erred in
    its determination that Holly could not assert his fifth
    amendment privilege. It is not perfectly clear from all
    of the circumstances that Holly’s testimony could not
    possibly have tended to incriminate him and, thus, pos-
    sibly subject him to prosecution. Because the record
    reveals that it was likely that the court would have
    honored Holly’s invocation of his fifth amendment privi-
    lege with respect to inquiries concerning his interaction
    with Ford on the day of the shooting, the petitioner
    cannot rely on Holly’s testimony at the habeas trial, or
    any substantive portion thereof, to demonstrate harm.
    In analyzing this claim, we have accepted as true the
    habeas court’s unchallenged finding that Holly would
    have testified at the petitioner’s criminal trial if he had
    been ordered to do so. Assuming, arguendo, that coun-
    sel’s failure to present Holly’s testimony was not the
    result of sound professional judgment, we conclude
    that such failure was not prejudicial to the petitioner.
    As we have explained in our analysis of this claim, it
    is speculative that the court, at the petitioner’s criminal
    trial, would not have honored Holly’s invocation of his
    privilege against self-incrimination with respect to
    inquiries concerning his interaction with Ford on the
    day of the shooting. On the scant record before us
    concerning Holly’s pending matters at the time of the
    criminal trial, any attempt by this court to determine
    what portions of Holly’s testimony, if any, would not
    have been subject to a specific claim of privilege and
    would have come before the jury would be speculative
    in nature.12
    Moreover, setting aside any issues related to Holly’s
    privilege against self-incrimination, it is purely specula-
    tive that any portions of Holly’s testimony would have
    been admissible as evidence of third party culpability.
    With respect to the admissibility of third party culpabil-
    ity evidence, our Supreme Court has stated: ‘‘The admis-
    sibility of evidence of third party culpability is governed
    by the rules relating to relevancy. . . . Relevant evi-
    dence is evidence having any tendency to make the
    existence of any fact that is material to the determina-
    tion of the proceeding more probable or less probable
    than it would be without the evidence. . . . Accord-
    ingly, in explaining the requirement that the proffered
    evidence establish a direct connection to a third party,
    rather than raise merely a bare suspicion regarding a
    third party, we have stated [that] [s]uch evidence is
    relevant, exculpatory evidence, rather than merely tenu-
    ous evidence of third party culpability [introduced by
    a defendant] in an attempt to divert from himself the
    evidence of guilt. . . . In other words, evidence that
    establishes a direct connection between a third party
    and the charged offense is relevant to the central ques-
    tion before the jury, namely, whether a reasonable
    doubt exists as to whether the defendant committed the
    offense. Evidence that would raise only a bare suspicion
    that a third party, rather than the defendant, committed
    the charged offense would not be relevant to the jury’s
    determination. A trial court’s decision, therefore, that
    third party culpability evidence proffered by the defen-
    dant is admissible, necessarily entails a determination
    that the proffered evidence is relevant to the jury’s
    determination of whether a reasonable doubt exists as
    to the defendant’s guilt. . . .
    ‘‘Whether a defendant has sufficiently established a
    direct connection between a third party and the crime
    with which the defendant has been charged is necessar-
    ily a fact intensive inquiry. In other cases, this court
    has found that proof of a third party’s physical presence
    at a crime scene, combined with evidence indicating
    that the third party would have had the opportunity to
    commit the crime with which the defendant has been
    charged, can be a sufficiently direct connection for pur-
    poses of third party culpability. . . . Similarly, this
    court has found the direct connection threshold satis-
    fied for purposes of third party culpability when physi-
    cal evidence links a third party to a crime scene and
    there is a lack of similar physical evidence linking the
    charged defendant to the scene. . . . Finally, this court
    has found that statements by a victim that implicate the
    purported third party, combined with a lack of physical
    evidence linking the defendant to the crime with which
    he or she has been charged, can sufficiently establish a
    direct connection for third party culpability purposes.’’

    State v. Baltas, 
    311 Conn. 786
    , 810–12, 
    91 A.3d 384
    (2014).
    In the present case, the petitioner did not present
    any evidence that Ford was armed at the time of the
    shooting, physical evidence that tied Ford to the shoot-
    ing scene, or a statement by the victim implicating Ford.
    Although the petitioner may have attempted to use Hol-
    ly’s testimony in an attempt to demonstrate that Ford
    was culpable for shooting the victim accidentally, there
    was no evidence that Ford had a motive to shoot the
    victim. In the absence of additional evidence tying Ford
    to the shooting, it is speculative whether the trial court
    would have viewed Holly’s testimony as proving a direct
    connection between Ford and the shooting, or whether
    it would have been viewed as evidence that supported
    a mere suspicion that he was implicated in the shooting.
    Under Strickland, the petitioner failed in his burden
    of demonstrating that his trial counsel’s failure to
    attempt to present Holly’s testimony was prejudicial in
    that there was a reasonable probability that, absent
    such failure, the outcome of the trial would have
    been different.13
    II
    Next, we consider the respondent’s claim that the
    habeas court erroneously concluded that the petitioner
    was deprived of his right to the effective assistance of
    counsel by his counsel’s failure to present evidence in
    support of an alibi defense that involved the testimony
    of Johnson and Allen to explain his whereabouts at the
    time of the shooting.14 We agree with the respondent
    that the petitioner failed to demonstrate that counsel’s
    strategic decision not to present the evidence at issue
    reflected deficient performance.
    The respondent challenges the court’s decision with
    respect to this aspect of the petitioner’s ineffective
    assistance of counsel claim on a variety of grounds.
    The respondent argues that the court did not afford
    adequate consideration to evidence that defense coun-
    sel did not present the alibi evidence as part of an
    objectively reasonable overall trial strategy that was
    opposed to diverting the jury’s attention away from the
    weaknesses of the state’s case and, in particular, the
    significance of Ford’s recantation at the time of the
    petitioner’s second trial. Likewise, the respondent
    argues that the court did not afford adequate consider-
    ation to evidence that, apart from their overall trial
    strategy, defense counsel had specific concerns about
    the strength of the alibi evidence as well as its potential
    favorability to the state’s case. Additionally, the respon-
    dent argues that the court erroneously concluded that
    there was a reasonable probability that, if the alibi evi-
    dence at issue had been presented to the jury, the result
    of the proceeding would have been different. Following
    a careful consideration of the claim, we agree with the
    respondent that the petitioner failed to demonstrate
    that counsel’s strategic decision not to present the evi-
    dence at issue constituted deficient performance under
    the Strickland standard.
    As stated previously in this opinion, to prevail under
    Strickland, ‘‘the petitioner must demonstrate that his
    attorney’s representation was not reasonably compe-
    tent or within the range of competence displayed by
    lawyers with ordinary training and skill in the criminal
    law.’’ (Internal quotation marks omitted.) Michael T. v.
    Commissioner of 
    Correction, supra
    , 
    319 Conn. 631
    .
    ‘‘With respect to the performance prong of Strickland,
    we are mindful that [j]udicial scrutiny of counsel’s per-
    formance must be highly deferential. It is all too tempt-
    ing for a defendant to second-guess counsel’s assistance
    after conviction or adverse sentence, and it is all too
    easy for a court, examining counsel’s defense after it
    has proved unsuccessful, to conclude that a particular
    act or omission of counsel was unreasonable. . . . A
    fair assessment of attorney performance requires that
    every effort be made to eliminate the distorting effects
    of hindsight, to reconstruct the circumstances of coun-
    sel’s challenged conduct, and to evaluate the conduct
    from counsel’s perspective at the time. Because of the
    difficulties inherent in making the evaluation, a court
    must indulge a strong presumption that counsel’s con-
    duct falls within the wide range of reasonable profes-
    sional assistance; that is, the defendant must overcome
    the presumption that, under the circumstances, the
    challenged action might be considered sound trial strat-
    egy. . . . There are countless ways to provide effective
    assistance in any given case. Even the best criminal
    defense attorneys would not defend a particular client
    in the same way. . . .
    ‘‘Similarly, the United States Supreme Court has
    emphasized that a reviewing court is required not sim-
    ply to give [the trial attorney] the benefit of the doubt
    . . . but to affirmatively entertain the range of possible
    reasons . . . counsel may have had for proceeding as
    [he] did . . . . [S]trategic choices made after thorough
    investigation of law and facts relevant to plausible
    options are virtually unchallengeable; [but] strategic
    choices made after less than complete investigation
    are reasonable precisely to the extent that reasonable
    professional judgments support the limitations on
    investigation.’’ (Citations omitted; emphasis in original;
    internal quotation marks omitted.) 
    Id., 632–33. ‘‘Although
    courts may not indulge post hoc rational-
    ization for counsel’s decisionmaking that contradicts
    the available evidence of counsel’s actions . . . neither
    may they insist counsel confirm every aspect of the
    strategic basis for his or her actions. There is a strong
    presumption that counsel’s attention to certain issues
    to the exclusion of others reflects trial tactics rather
    than sheer neglect. . . . After an adverse verdict at
    trial even the most experienced counsel may find it
    difficult to resist asking whether a different strategy
    might have been better, and, in the course of that reflec-
    tion, to magnify their own responsibility for an unfavor-
    able outcome. Strickland, however, calls for an inquiry
    into the objective reasonableness of counsel’s perfor-
    mance, not counsel’s subjective state of mind.’’ (Cita-

    178 L. Ed. 2d 624
    (2011). The presumption that

    showing that there was no conceivable tactical justifica-
    tion for counsel’s strategy. See, e.g., Holloway v. Com-

    145 Conn. App. 353
    , 367, 
    77 A.3d 777
    (2013).
    At the habeas trial, Merkin testified that the defense
    strategy was to discredit Ford’s credibility and to chal-
    lenge the strength of the state’s case, particularly with
    respect to the state’s evidence identifying the petitioner
    as the shooter. Merkin testified that the defense
    attempted to challenge Ford’s earlier statements to the
    police, in which he implicated the petitioner, as being
    inherently unreliable. Merkin explained: ‘‘Part of our
    theory was that [Ford] wasn’t in a location where he
    could see what he claimed to have seen. Part of it was
    that he was very coercively, in our view, interrogated
    by the lead detective in the case in the middle of the
    night, and therefore the information he gave was not
    reliable. And part of it was that we had some suspicion
    or belief that he was actually involved himself, whether
    accidentally or otherwise killing his friend.’’ Merkin
    acknowledged, however, that defense counsel had not
    developed enough evidence to support the latter part
    of the defense strategy. Consistent with Merkin’s testi-
    mony, the court found that Merkin ‘‘does not like alibi
    defenses generally, and her practice was not to present
    an alibi defense unless it was rock solid.’’15
    The court found that, through defense investigation,
    defense counsel became aware of the potential trial
    testimony of Johnson and Allen, and that defense coun-
    sel had found Johnson and Allen to be credible wit-
    nesses. The court observed that Merkin decided not to
    present the testimony of Johnson because she did not
    believe it was strong evidence. In this regard, the court
    referred to Merkin’s opinions that Johnson was not a
    disinterested witness because she was the petitioner’s
    sister, Johnson’s testimony supported a finding that the
    petitioner was close to the crime scene at the time
    that the shooting occurred, and it was unclear from
    Johnson’s testimony whether the petitioner was able
    directly to observe the petitioner at all times relevant.
    With respect to Allen, the court referred to Merkin’s
    opinions that Allen’s testimony was not strong because
    she merely had estimated the timing of the telephone
    calls involving the petitioner, and that the testimony
    was potentially more favorable to the state’s case, par-
    ticularly in light of the fact that the evidence would
    have placed the petitioner in close proximity to the
    crime scene at the time that the shooting occurred.16
    Consistent with the testimony of Merkin and Jones,
    the court recognized that trial counsel’s failure to pre-
    sent the testimony of Johnson and Allen was not inad-
    vertent, but the result of a considered trial strategy. In
    general terms, the strategy was designed to focus the
    jury’s attention on weaknesses in the state’s case, par-
    ticularly the fact that Ford had recanted his earlier
    statements in which he had identified the petitioner as
    being present at the scene of the crime with a gun. In
    this general sense, defense counsel did not want the
    jury to focus on possible weaknesses in its alibi defense
    or to afford the prosecutor an opportunity to draw the
    jury’s attention away from the state’s case. In specific
    terms, defense counsel also expressed concerns that
    were directly related to potential issues with the
    strength of the potential testimony of Johnson and
    Allen, as well as concerns that their testimony, if found
    to be credible by the jury, had the potential to assist
    the state by demonstrating that, at or around the time
    of the shooting, the petitioner was at his residence, just
    two blocks away from the crime scene.
    The court, however, did not view defense counsel’s
    general strategic decision to be reasonable because, as
    it found, the alibi testimony at issue ‘‘would have been
    helpful to the petitioner’s defense that he was at home
    at the time of the shooting.’’ The court did not appear
    to afford any deference to defense counsel’s concern
    that presenting the alibi defense would have diverted
    the jury’s attention away from the weaknesses of the
    state’s case, particularly in light of the fact that Merkin
    believed that the defense had done a ‘‘very good job’’
    in undermining Ford’s identification of the petitioner.
    Additionally, rather than evaluating whether there
    existed conceivable tactical justifications for counsel’s
    assessment of the alibi evidence, the court set forth a
    number of reasons as to why it did not share trial coun-
    sel’s concerns about the strength of the alibi testimony.
    For example, the court, relying on Johnson’s testimony,
    determined that she was able to provide a strong alibi
    for the petitioner despite the fact that the petitioner
    was not in her direct view at times relevant.17 The court
    determined that any confusion concerning the timing
    of calls made between Allen and the petitioner could
    have been resolved by means of evidence obtained from
    the caller identification feature on Allen’s telephone.18
    Moreover, the court determined that counsel’s concern
    that the alibi evidence would have placed the petitioner
    close to the crime scene at the time of the shooting
    was unfounded because there was what it considered to
    be evidence of a similar nature before the jury, namely,
    evidence that the petitioner was at Southern Connecti-
    cut State University shortly before 11 p.m. on the night
    of the shooting.19
    Affording plenary review to the issue, we conclude
    that the representation that the defendant was afforded
    was constitutionally adequate. The petitioner has failed
    to sustain his evidentiary burden of demonstrating that,
    under all of the circumstances, defense counsel’s strate-
    gic decision not to present the alibi defense was not
    objectively reasonable. Here, defense counsel
    described at length the reasons underlying their deci-
    sion not to present the alibi evidence, and the court
    found that the decision was not the product of neglect,
    but strategy. It is not the role of a reviewing court to
    second-guess the myriad of considerations that underlie
    a trial strategy in an attempt to determine with the
    benefit of hindsight whether it would have made the
    exact same strategic decisions. Rather, a reviewing
    court must determine whether, at the time of trial, con-
    ceivable justifications existed for the tactical decisions
    that were made by counsel.
    ‘‘Our review of an attorney’s performance is espe-
    cially deferential when his or her decisions are the result
    of relevant strategic analysis. . . . Thus, [a]s a general
    rule, a habeas petitioner will be able to demonstrate that
    trial counsel’s decisions were objectively unreasonable
    only if there [was] no . . . tactical justification for the
    course taken. . . .
    ‘‘[T]he presentation of testimonial evidence is a mat-
    ter of trial strategy. . . . Defense counsel will be
    deemed ineffective only when it is shown that a defen-
    dant has informed his attorney of the existence of a
    witness and that the attorney . . . without adequate
    explanation . . . failed to call the witness at trial. . . .
    Furthermore, [t]he failure of defense counsel to call a
    potential defense witness does not constitute ineffec-
    tive assistance unless there is some showing that the
    testimony would have been helpful in establishing the
    asserted defense. . . .
    ‘‘[O]ur habeas corpus jurisprudence reveals several
    scenarios in which courts will not second-guess defense
    counsel’s decision not to investigate or call certain wit-
    nesses or to investigate potential defenses, such as
    when . . . counsel learns of the substance of the wit-
    ness’ testimony and determines that calling that witness
    is unnecessary or potentially harmful to the case . . . .
    Thus, an attorney’s choice to pursue a defense that
    focuses on casting doubt on the state’s case rather than
    on calling his or her own witnesses can be a reasonable
    choice.’’ (Citations omitted; internal quotation marks
    omitted.) Spearman v. Commissioner of Correction,
    
    164 Conn. App. 530
    , 541,        A.3d      (2016). As the
    United States Supreme Court has observed, ‘‘To support
    a defense argument that the prosecution has not proved
    its case it sometimes is better to try to cast pervasive
    suspicion of doubt than to strive to prove a certainty
    that exonerates.’’ Harrington v. 
    Richter, supra
    , 
    562 U.S. 109
    .
    The petitioner failed to demonstrate that defense
    counsel’s general strategy to keep the jury’s focus on
    weaknesses in the state’s case, instead of diverting
    focus to an alibi defense, was unreasonable under the
    circumstances. This is particularly true in light of the
    weakness in the state’s case following Ford’s recanta-
    tion. Moreover, even if the petitioner could demonstrate
    that such a general strategic decision was unreasonable,
    in the present case, defense counsel raised many rea-
    sonable concerns about the overall strength of the alibi
    evidence, including its potential to benefit the state’s
    case by placing the petitioner near the scene of the
    crime at the time that it was committed. The petitioner
    has failed to demonstrate that, as a whole, these specific
    reasons related to defense counsel’s evaluation and
    assessment of the alibi evidence did not reflect sound
    professional judgment.20 The fact that this was not the
    only reasonable trial strategy that was available to coun-
    sel, or that it ultimately was not successful, is not dis-
    positive of the issue of whether the strategy employed
    was objectively reasonable. Employing the strong pre-
    sumption that counsel’s conduct reflected reasonable
    representation, as we must, we conclude that the peti-
    tioner failed to satisfy his burden under Strickland’s
    first prong.
    The judgment is reversed only with respect to the
    count alleging ineffective assistance of counsel and the
    case is remanded to the habeas court with direction to
    deny the petition for a writ of habeas corpus on that
    count. The judgment is affirmed in all other respects.
    In this opinion the other judges concurred.

    ‘‘The police, relying on information received and the identifications made
    by Ralph Ford and L’Kaya Ford, secured a search warrant for the [petition-
    er’s] residence and seized a .45 caliber handgun. Ballistics testing confirmed
    that the gun seized from the [petitioner’s] home was not the gun used to
    kill the victim. The parties stipulated at trial that there was no record of a
    permit in the defendant’s name to carry a handgun. The police also seized
    a pair of black, high-top sneakers from the [petitioner’s] home but did not

    Also, the petitioner alleged that counsel rendered deficient representa-
    tion in that they had failed to present testimony of a Jermaine Diggs, who
    was not called as a witness at the habeas trial. The habeas court determined
    that the petitioner abandoned this aspect of his claim of ineffective
    assistance.

    The petitioner presented Holly’s testimony before the habeas court as
    evidence of prejudice. Before this court, the petitioner observes that, at the
    time of the criminal trial, the court could have ordered Holly to testify while
    restricting direct and cross-examination of him in such a manner as to
    protect his right against self-incrimination. Thus, the petitioner argues that
    Holly’s testimony at the criminal trial ‘‘could have been limited to the sole
    issue of his having seen Ford with a gun similar to that used to kill the
    victim near the time of the shooting.’’ The petitioner argues that Holly ‘‘would
    have been required to answer questions about having seen Ford with a gun
    and asking him to describe the gun, even if he would have been permitted
    to invoke the privilege in response to questions about trying to take the
    gun.’’ The petitioner’s argument in this regard is based on his assertion that
    ‘‘it is perfectly clear from all of the facts presented at the habeas trial that
    answers from Holly to questions calling for information about his having
    seen a gun and a description of that gun could not possibly have any tendency
    to incriminate him.’’
    Holly was not called as a witness at the petitioner’s criminal trial and, at
    the habeas trial, Holly testified without invoking his privilege against self-
    incrimination. A hearing concerning what inquiries, if any, would have been
    precluded by the exercise of Holly’s privilege did not occur in this case.
    Thus, the petitioner invites this court to speculate with respect to the portion
    of that testimony that the petitioner would have been compelled to provide
    consistent with the invocation of his privilege. A court’s evaluation of
    whether to preclude the exercise of the fundamental constitutional right
    at issue is inherently fact-bound. ‘‘To sustain the privilege [against self-
    incrimination], it need only be evident from the implications of the question,
    in the context in which it is asked, that a responsive answer to the question
    or an explanation of why it cannot be answered might be dangerous because
    injurious disclosure could result. . . . Conversely, before refusing to allow
    the privilege, the trial court must find that the answers to any questions
    proposed cannot possibly have a tendency to incriminate. . . . The privilege
    against self-incrimination depends on the mere possibility of prosecution.’’

    32 Conn. App. 811
    , 819, 
    631 A.2d 862
    (1993). We reject the petitioner’s argument.
    In the absence of a factual record that provides far greater information
    concerning the matters pending against Holly at the time of the criminal
    trial, it is not perfectly clear that any testimony from Holly in which he
    described his interaction with Ford and his observations of Ford’s gun could
    not possibly have any tendency to incriminate him. If it would have been
    feasible and likely for the court to have limited the inquiries of Holly in
    the manner suggested by the petitioner, it was the petitioner’s burden to
    demonstrate this fact before the habeas court on the basis of adequate facts.
    We reiterate that it was the petitioner’s burden to create a factual record
    to demonstrate that Holly would not have been permitted to exercise his
    privilege against self-incrimination with respect to evidence helpful to the
    petitioner.
    13
    As discussed previously in this opinion, the petitioner relies on Holly’s
    testimony before the habeas court to demonstrate that, under Strickland,
    he was prejudiced by counsel’s failure to present Holly’s testimony at his
    criminal trial. Alternatively, the petitioner argues that this court ‘‘should
    hold that [he] need not prove prejudice because [his] trial counsel’s failure
    to present evidence of third party culpability through . . . Holly was an
    adverse effect of counsel’s conflict of interest.’’
    This conflict of interest claim was raised before and rejected on its merits
    by the habeas court. In relevant part, the court stated: ‘‘[T]he petitioner
    alleges that trial counsel had a duty to present Holly and Inspector Whalen
    as witnesses to testify at the second trial as to Holly’s statement that he
    saw Ford in possession of a pistol matching the description of the murder
    weapon [on] the day of the shooting. The petitioner further claims that trial
    counsel failed to present this testimony because Attorney Ullmann, the head
    of the New Haven public defender’s office and trial counsel’s supervisor,
    represented Holly in an unrelated [matter] and advised Holly not to cooperate
    with the petitioner’s defense. This, he claims, constituted a conflict of
    interest.
    ***
    ‘‘At the time of the petitioner’s second criminal trial, Holly had a criminal
    matter pending that was unrelated to the petitioner’s case. Attorney Ullmann
    represented Holly in that matter. Inspector Whalen contacted Holly on behalf
    of the petitioner’s defense, and Holly informed him that he had seen Ford
    with a handgun with a description similar to the murder weapon. Attorney
    Ullmann advised Holly not to testify at the petitioner’s criminal trial because
    the same prosecutor was handling both the petitioner’s case and Holly’s
    pending case, and he did not want the prosecutor to retaliate against Holly
    in his case for assisting the petitioner’s defense. Attorney Ullmann subse-
    quently appointed a private attorney, Attorney Farver, to represent Holly
    with respect to Holly’s involvement in the petitioner’s case. Both Attorney
    Jones’ and Attorney Merkin’s decision not to call Holly as a witness at the
    petitioner’s trial was not impacted by the fact that Attorney Ullmann was
    their supervisor, and had advised Holly not to testify. . . .
    ‘‘[A]n actual conflict of interest does not arise in the present case solely
    because trial counsel and Attorney Ullmann worked in the same government
    office while representing parties with adverse interests. Further, the court
    finds no specific instances in which the petitioner’s interests have been
    adversely affected by trial counsel’s representation. Attorney Ullmann
    appointed a private attorney to represent Holly with respect to the petition-
    er’s case to avoid any potential conflict, and both Attorney Jones and Attor-
    ney Merkin testified that Attorney Ullmann’s status as their supervisor or
    [his] position as to Holly’s testimony did not impact their decision not to
    call him as a witness in the petitioner’s second trial. Accordingly, the peti-
    tioner has failed to prove his actual conflict of interest claim.’’
    In arguing before this court that a conflict of interest actually existed that
    obviated the requirement that he prove that he was prejudiced by defense
    counsel’s failure to present Holly’s testimony, the petitioner argues that the
    habeas court erred in its critical finding that Ullmann did not have any
    adverse effect on defense counsel’s representation of him, and that Ullmann
    did not impact their decision not to present Holly’s testimony. The petition-
    er’s argument with respect to an actual conflict of interest on the part of
    defense counsel is not persuasive. Before this court, the petitioner calls into
    question the factual determinations of the habeas court with respect to
    defense counsel’s loyalties and their decision-making concerning Holly. His
    arguments fail because the court’s unambiguous factual findings in this
    regard are amply supported by the testimony presented at the habeas trial.
    14
    In his brief before this court, the petitioner asserts that the judgment
    of the habeas court may be supported by the fact that defense counsel
    ‘‘failed to adequately investigate the strength of the petitioner’s alibi.’’ He
    argues that ‘‘trial counsel failed to adequately investigate the strength of
    the alibi witnesses’’ and ‘‘had no reasonable basis to stop investigating before
    discovering [relevant] facts’’ related to their testimony. The petitioner argued
    that, had defense counsel questioned Johnson adequately, they would have
    learned that he could not have left his residence without alerting her that
    he was doing so.
    The petitioner’s arguments that are based upon an inadequate investiga-
    tion are not properly before us. In his amended petition for a writ of habeas
    corpus, the pleading that framed the issues before the court, the petitioner
    did not set forth allegations related to deficiencies in defense counsel’s
    investigation of the alibi witnesses. Rather, he alleged that defense counsel
    had ‘‘failed to present’’ the testimony of Johnson and Allen. Moreover, the
    habeas court’s memorandum of decision does not reflect that the court
    considered on its merits any claim related to inadequate investigation of
    the witnesses at issue. The court stated among its many findings that, at
    the habeas trial, defense counsel ‘‘acknowledged . . . that they failed to
    investigate Johnson’s ability to provide an alibi at the times when the peti-
    tioner was not in her direct view.’’ There is nothing in the court’s decision
    to reflect, however, that the court based its decision on that isolated finding
    or any theory of the case related to defense counsel’s investigation. Consis-
    tent with the grounds set forth in the amended petition for a writ of habeas
    corpus, the court stated that the issue before it was the petitioner’s claim
    ‘‘that trial counsel were ineffective for failing to call Johnson and Allen as
    witnesses to testify that he was at home at the time of the shooting in
    support of an alibi defense.’’
    This is not one of the rare cases in which, in the absence of an amendment
    to the operative pleadings, a lower court has considered, or granted relief,
    on the basis of a technically unpleaded claim that was actually litigated at
    trial. See Stafford Higgins Industries, Inc. v. Norwalk, 
    245 Conn. 551
    , 575,
    
    715 A.2d 46
    (1998). ‘‘It is well settled that [t]he petition for a writ of habeas
    corpus is essentially a pleading and, as such, it should conform generally
    to a complaint in a civil action. . . . The principle that a [petitioner] may
    rely only upon what he has alleged is basic. . . . It is fundamental in our
    law that the right of a [petitioner] to recover is limited to the allegations
    of his complaint. . . . While the habeas court has considerable discretion
    to frame a remedy that is commensurate with the scope of the established
    constitutional violations . . . it does not have the discretion to look beyond
    the pleadings and trial evidence to decide claims not raised. . . . This court
    is not bound to consider claimed errors unless it appears on the record that
    the question was distinctly raised . . . and was ruled upon and decided by
    the court adversely to the [petitioner’s] claim. . . . This court is not com-
    pelled to consider issues neither alleged in the habeas petition nor consid-
    ered at the habeas proceeding . . . .’’ (Citation omitted; internal quotation

    decline to address on their merits any arguments related to the alleged
    deficient performance of defense counsel in failing to properly investigate
    the strength of the alibi witnesses’ potential testimony.

    In this regard, Merkin testified: ‘‘It was my belief . . . from years of
    doing this type of work . . . that unless they are solid, [alibis] can get you
    into trouble. It’s the last thing the jury hears if you have a good prosecutor
    who’s a good cross-examiner and can try to kind of attack either a family
    member who’s an alibi witness or some other vulnerability to the alibi. To
    me, it pulls attention away from the weaknesses in the state’s case, and it
    kind of develops jurors’ focus on the weaknesses in the alibi. So, it’s just
    been my practice to shy away from alibis unless they’re solid, and I had
    some concerns about the alibi in this case.’’
    Similarly, Merkin stated: ‘‘I know that there’s a difference of opinion on
    this . . . . My opinion is that if you put alibi evidence on which has vulnera-
    bilities, after the state’s sole eyewitness testifies . . . the last piece of the
    case that the jury is left with is a weak or possibly problematic alibi, and
    it draws the jury’s attention away from the weaknesses in the state’s case.
    Jurors aren’t supposed to shift burdens and things of that sort, but it’s my
    opinion that . . . if they’re presented with alibi evidence that’s not solid,
    their focus kind of gets taken away from the weaknesses in the state’s case.’’
    16
    Defense counsel did not testify that they disbelieved Johnson or Allen.
    Merkin testified that she had a wide range of concerns with respect to
    presenting the testimony of Johnson and Allen in support of an alibi defense.
    Merkin explained that Johnson was not a disinterested witness, but a family
    member of the petitioner; the alibi evidence would have demonstrated that
    the petitioner was close to the scene of the shooting at the time that the
    shooting occurred; and she believed that Johnson’s testimony was not strong
    because Johnson had not informed the police about the petitioner’s where-
    abouts. Merkin also explained that Johnson was not always consistent with
    respect to when she had observed the petitioner leave the residence, and
    that she did not believe that Johnson’s version of events would withstand
    a thorough cross-examination because it would have been relatively easy
    for a skilled prosecutor to draw the jury’s attention to the fact that she did
    not directly observe the petitioner at all times relevant. She stated that the
    fact that Johnson was unable to testify that she directly had observed the
    petitioner in her residence at the time of the shooting was a deficiency in
    the alibi.
    Merkin explained that because of uncertainties in Allen’s testimony, she
    was not satisfied that it would have precluded the jury from finding that
    the petitioner committed the shooting and, in any event, it demonstrated
    that he was in close proximity to the crime scene at the time of the shooting.
    Moreover, Merkin believed that Allen’s testimony was not favorable to the
    extent that it essentially demonstrated that the petitioner had asked Allen
    to drive him away from the general area of the crime scene at a late hour
    of the day. With respect to this last observation, Merkin testified that she
    had concerns that such evidence would have permitted the state to seek
    an instruction concerning evidence of flight and consciousness of guilt, to
    the petitioner’s detriment. She stated: ‘‘I didn’t like that because the jurors
    could infer that he had maybe done the shooting and was taking off
    [with Allen].’’
    Repeatedly, Merkin indicated that she deemed the fact that the alibi
    evidence would have placed the petitioner near the scene of the shooting
    to be an important factor that mitigated against presenting the evidence at
    issue. Despite her reservations about alibi defenses, Merkin testified that if
    the alibi evidence had placed the petitioner farther away from the scene of
    the crime she would not have ‘‘struggled’’ with the decision whether to
    present the evidence. Merkin testified that if Johnson and Allen could have
    supported an alibi that was ‘‘connected to a location miles away from the
    crime . . . the balance for me would have tipped in favor of putting that
    defense on in front of this jury.’’
    In his testimony before the habeas court, Jones discussed the general
    defense strategy of focusing on the weakness of Ford’s identification of the
    petitioner. Jones shared some of Merkin’s concerns with respect to the
    strength of the alibi evidence, particularly the concern that the evidence
    did not provide a rock-solid alibi that, if believed, precluded a finding that
    the petitioner could have committed the crime. Jones observed that the
    alibi evidence would have placed the petitioner at his home, which was
    located mere blocks from the crime scene. Jones expressed his concern
    that, even if the alibi evidence had been presented to the jury, the jury could
    have found it plausible that the petitioner had the opportunity to commit
    the crime. Jones, like Merkin, wrestled with the issue of whether it was a
    good strategy to divert the jury’s attention to an alibi defense, but he indicated
    that he favored presenting the alibi evidence. Despite this disagreement
    with her as to trial strategy, he viewed Merkin as an excellent trial attorney
    and agreed with her overall assessment of the weaknesses in the state’s case.
    17
    In this regard, the court appears to have relied on Johnson’s testimony
    that, even if she was not able to directly view the petitioner, she would
    have been able to determine if he had left the residence because she would
    have heard the kitchen door open and would have noticed if the motion-
    activated light outside of her residence had been activated by his movement.
    The court found, and the evidence reflects, that defense counsel did not
    investigate Johnson’s testimony in this regard. Even if defense counsel had
    been aware of this explanation from her, however, it would not have been
    unreasonable for counsel, in the exercise of sound professional judgment,
    to determine that the evidence was not persuasive in nature.
    18
    Although the court appears to have determined that the defense could
    have presented evidence of this nature with respect to all calls made between
    the petitioner and Allen on the night of the shooting, Allen testified that the
    caller identification system on her telephone contained information about
    the telephone calls that the petitioner made to her. Allen testified that the
    system did not have information about the timing of the telephone calls
    that she allegedly had made to the petitioner closer to the suspected time
    of the shooting. Thus, the evidence presented at the habeas trial did not
    undermine the sound strategic reasons articulated by Merkin for not pre-
    senting Allen’s testimony.
    19
    There was evidence that the shooting occurred between 10:20 and 10:30
    p.m. There was evidence that the petitioner’s residence was within two
    blocks of the crime scene and that it took the petitioner several minutes
    to drive to Southern Connecticut State University from his residence. Thus,
    the evidence showing that the petitioner was at Southern Connecticut State
    University shortly before 11 p.m. is not as potentially incriminating as the
    alibi evidence that would have placed the petitioner at his residence, just
    two blocks from the crime scene, at a time that was much closer to the
    suspected time of the shooting.
    20
    Although the court did not refer to it when assessing the reasonableness
    of defense counsel’s strategic decision not to present Johnson’s testimony,
    we note that an excerpt from one of the police incident reports that was
    introduced as an exhibit during the habeas trial reflects that, on the day
    following the shooting, the petitioner, after signing a waiver of rights form,
    told the police that he was home at his residence on Butler Street the night
    before, but he ‘‘could not remember who was home or saw him.’’
