    LENK, J.   The defendant was convicted as a joint venturer
    of murder in the first degree, armed robbery, and assault and
    battery by means of a dangerous weapon in connection with the
    death of William Jones in January, 2010.    On direct appeal from
    that conviction, he argues that his motions for required
    findings of not guilty should have been granted, and that his
    case should have been dismissed on speedy trial grounds.     In
    addition, he argues that certain evidence, including his
    statements to police, should not have been admitted at trial.
    The defendant also seeks relief under G. L. c. 278, § 33E.
    Having reviewed the entire record, we affirm the convictions and
    discern no reason to exercise our authority to grant
    extraordinary relief.
    1.   Factual background.    We recite the facts the jury could
    have found, reserving certain details for later discussion.       At
    approximately 8 A.M. on January 22, 2010, the defendant, an
    employee at a tomato processing plant in Hartford, Connecticut,
    told his supervisor that he needed to leave work in order to
    conduct a drug deal.    The supervisor gave him permission to
    leave, and the defendant was picked up by Jones in a white
    Saturn sport utility vehicle (SUV).    The pair drove to a house
    on Florida Street in Springfield, where Jones, a drug dealer,
    had been led to believe that he would buy drugs from Curtis
    Combs, an acquaintance of the defendant.    The defendant,
    3
    however, knew that Jones was going to be robbed.     He went into
    the house to introduce Jones to Combs, but returned outside to
    serve as a lookout.
    The defendant heard "tussling" inside the house as well as
    a "zzzt, zzzt" sound.     Combs then brought Jones out of the house
    while striking him in the back of the neck with a stun gun.
    After Jones was placed in the back seat of the Saturn, the
    defendant drove the vehicle to the parking lot of a grocery
    store in Bloomfield, Connecticut.     The defendant left Jones in
    the Saturn, and was driven back to his workplace in another
    vehicle.
    The defendant returned to work around 12:30 P.M.   He told
    his coworkers that he had made a profit on the deal, and offered
    to buy them all lunch.     In addition, he gave ten dollars each to
    his supervisor and to another coworker.     At one point, he fanned
    out approximately $4,000 to $5,000, mostly in one hundred dollar
    bills.     The following evening, Jones's body was found lying
    across the back seat of the Saturn in the grocery store parking
    lot.    At trial, a medical examiner testified that the cause of
    his death was ligature strangulation.
    The investigation of Jones's death was undertaken primarily
    by officers of the Bloomfield, Connecticut, police department
    over a two-week period in early 2010.     While searching the
    Saturn pursuant to a warrant, police found the fingertip from a
    4
    latex glove on the floor beneath the back seat.   Jones's and the
    defendant's deoxyribonucleic acid (DNA) profiles were both
    determined to be contributors to a DNA profile found on the
    glove fingertip, and to another DNA profile found on one of the
    headrests in the vehicle.2   The defendant routinely wore latex
    gloves of the same type as part of his work at the tomato
    processing plant.
    Officers of the Bloomfield police department first
    interviewed the defendant at his workplace on January 25, 2010.
    Unbeknownst to the defendant, one of the interviewing officers
    was carrying a pen recorder that audiotaped their conversation,
    as permitted under Connecticut law.   The defendant told police
    that Jones had arranged to meet with him on January 22, 2010,
    but did not show up.   He provided the police with a written,
    signed statement to that effect.
    Video footage from the tomato processing plant, however,
    showed that the defendant was picked up from work in a white
    SUV, and dropped off again by a different vehicle around 12:30
    2
    The expected frequency of individuals who could be a
    contributor to the deoxyribonucleic acid (DNA) profile on the
    latex glove fingertip was approximately 1 in 1.2 million in the
    African-American population, 1 in 2.6 million in the Caucasian
    population, and 1 in 4.4 million in the Hispanic population.
    The expected frequency of individuals who could be a contributor
    to the DNA profile on the headrest was approximately 1 in 1,800
    in the African-American population, 1 in 2,500 in the Caucasian
    population, and 1 in 4,400 in the Hispanic population. Jones
    was apparently African-American, as is the defendant.
    5
    P.M on the day in question.      In addition, cellular site location
    information (CSLI) for Combs's and the defendant's cellular
    telephones supported an inference that, during that time period,
    the defendant had traveled from his workplace to Springfield to
    meet Combs, and that the pair had traveled back to the
    defendant's workplace via Bloomfield.
    On February 2, 2010, police confronted the defendant with
    this evidence during a second interview at the Bloomfield police
    station, which also was recorded without his knowledge by the
    same means.      As it became clear to the defendant that what he
    was saying conflicted with evidence police already had obtained,
    he changed his story several times.      Eventually, he explained
    that he had driven with Jones from his workplace to visit Combs
    in Springfield, on the understanding that Jones would be robbed.
    He described the use of the stun gun and his role as a lookout,
    and stated that he had driven Jones to the grocery store parking
    lot.       He provided police with a written, signed statement
    summarizing that version of events as well.3      The defendant was
    not arrested at that time.
    3
    Approximately one week into their investigation,
    Bloomfield police officers considered searching the house on
    Florida Street in Springfield. They stopped pursuing this lead,
    however, after a Hampden County assistant district attorney
    informed them that he considered an application for a search
    warrant unlikely to succeed in Massachusetts because the
    information was "stale."
    6
    For reasons that are not clear from the record, the
    investigation then stalled until February, 2011, when a trooper
    of the Massachusetts State police was assigned to the case.       The
    trooper interviewed several potential witnesses and obtained
    buccal swabs from the defendant and others that were used for
    additional DNA testing.    In September, 2011, the Hampden County
    district attorney sought indictments against the defendant, and
    he was arraigned in Massachusetts on October 4, 2011.
    2.    Procedural posture.   On September 26, 2011, a grand
    jury returned four indictments, charging the defendant with
    murder in the first degree, G. L. c. 265, § 1; kidnapping, G. L.
    c. 265, § 26; armed robbery, G. L. c. 265, § 17; and assault and
    battery by means of a dangerous weapon, G. L. c. 265, § 15A (b).4
    The Commonwealth proceeded on a joint venture theory of
    liability, with Combs as a joint venturer.5    Prior to trial, a
    nolle prosequi was entered with respect to the kidnapping
    charge.    The defendant filed a motion to dismiss the remaining
    charges on speedy trial grounds pursuant to Mass R. Crim. P. 36,
    as amended, 
    422 Mass. 1503
     (1996).     That motion was denied, and
    a petit jury was convened in the Superior Court.
    4
    The bill of particulars stated that Jones was strangled to
    death by means of a ligature. The indictments for armed robbery
    and for assault and battery by means of a dangerous weapon both
    stated that the dangerous weapon used was a stun gun.
    5
    Combs was tried separately.
    7
    At the close of the Commonwealth's case, the defendant
    filed a motion for a required finding of not guilty, which was
    denied.   The defendant's theory of the case was based on the
    inadequacy of the investigation and on the insufficiency of the
    evidence; he did not introduce any evidence.
    The defendant was convicted on all charges.     His conviction
    of murder in the first degree was based on two theories:
    felony-murder based on the predicate felony of armed robbery,
    and extreme atrocity or cruelty.   Immediately after the verdict,
    the defendant filed a motion for a required finding of not
    guilty, pursuant to Mass. R. Crim. P. 25, as amended, 
    420 Mass. 1502
     (1995), which also was denied.    This appeal followed.
    3.    Discussion.   The defendant argues that the denials of
    his motions for required findings and his motion to dismiss on
    speedy trial grounds were error.   He also argues that the judge
    erred in admitting certain evidence:     the defendant's recorded
    statements to police and transcripts of those statements; the
    testimony of a substitute medical examiner; cellular telephone
    records; and DNA evidence taken from the latex glove fingertip.
    In addition, he seeks relief pursuant to G. L. c. 278, § 33E.
    These issues are addressed in turn below.
    a.    Sufficiency of the evidence.    The defendant contends
    that there was insufficient evidence to convict him as a joint
    venturer with respect to any of the indictments.     In reviewing
    8
    the denial of a motion for a required finding, we consider
    "whether, after viewing the evidence in the light most favorable
    to the prosecution, any rational trier of fact could have found
    the essential elements of the crime beyond a reasonable doubt"
    (emphasis in original).    Commonwealth v. James, 
    424 Mass. 770
    ,
    784 (1997), quoting Commonwealth v. Latimore, 
    378 Mass. 671
    , 677
    (1979).   "[T]he evidence and the inferences permitted to be
    drawn therefrom must be 'of sufficient force to bring minds of
    ordinary intelligence and sagacity to the persuasion of [guilt]
    beyond a reasonable doubt.'"    Commonwealth v. Semedo, 
    456 Mass. 1
    , 8 (2010), quoting Commonwealth v. Latimore, 
    supra.
    Because the defendant was convicted as a joint venturer, to
    affirm the denial of the motion for a required finding we must
    conclude that the evidence was "sufficient to permit a rational
    juror to conclude beyond a reasonable doubt that the defendant
    knowingly participated in the commission of the crime[s]
    charged, with the intent required to commit the crime[s]."
    Commonwealth v. Zanetti, 
    454 Mass. 449
    , 468 (2009).
    i.   Felony-murder.   The defendant contends that the
    evidence was insufficient to prove that he was a joint venturer
    in an armed robbery that resulted in Jones's death.6    To find the
    defendant guilty of murder in the first degree on a theory of
    6
    See Commonwealth v. Rodriquez, 
    454 Mass. 215
    , 216 n.3
    (2009) (noting that armed robbery can be underlying felony for
    felony-murder).
    9
    felony-murder with armed robbery as the predicate felony, a
    rational juror must have been able to find beyond a reasonable
    doubt that the defendant was a joint venturer in an armed
    robbery and that Jones's death occurred "in the commission or
    attempted commission of" that robbery.   See G. L. c. 265, § 1;
    Zanetti, supra at 468.
    To find the defendant guilty of the underlying felony of
    armed robbery, proof was required that at least one of the
    alleged coventurers was armed with a dangerous weapon; either
    applied actual force or violence to Jones's body, or by words or
    gestures put him in fear; took Jones's money or property; and
    did so with the intent (or sharing the intent) to steal it.     See
    Commonwealth v. Benitez, 
    464 Mass. 686
    , 689-690 (2013), citing
    Commonwealth v. Rogers, 
    459 Mass. 249
    , 252 n.4, cert. denied,
    
    132 S. Ct. 813
     (2011).   In the absence of proof that the
    defendant himself was armed with a dangerous weapon, proof that
    the defendant knew that Combs was so armed would satisfy the
    first element of armed robbery.   See Benitez, supra at 689 n.4,
    citing Commonwealth v. Fickett, 
    403 Mass. 194
    , 196–197 (1988).
    In the defendant's view, there was no evidence that Jones was
    killed in the commission of a robbery, that the defendant knew
    10
    that Combs would use a stun gun during the robbery,7 or that
    anything was taken from Jones.
    We disagree.   The defendant told police that he knew Combs
    would rob Jones, that he saw Combs repeatedly assault Jones with
    a stun gun, and that he drove an injured Jones to Bloomfield,
    Connecticut.   In addition, a witness testified that on the day
    Jones was killed he had observed Combs and another African-
    American man at the house on Florida Street in Springfield,
    excitedly looking at something in the back seat of the Saturn.
    This evidence would have allowed a rational juror to conclude
    that Jones was killed in the commission of an armed robbery.
    Because Jones knew the defendant, an inference reasonably could
    be drawn that the defendant had an incentive to ensure that
    Jones would not retaliate after being robbed.   Although the
    defendant claimed that Jones was still alive during the drive to
    Bloomfield, he repeatedly changed his story during his
    interviews with police.   It would have been reasonable to infer
    that an incapacitated Jones was killed in Springfield in the
    7
    The defendant also argues on this basis that there was
    insufficient evidence for the jury to conclude beyond a
    reasonable doubt that he was a joint venturer in an assault and
    battery by means of a dangerous weapon against Jones. That
    argument is unavailing for the same reasons discussed below.
    11
    course of the robbery, during or shortly after Combs's sustained
    assault with the stun gun.8
    Furthermore, there was sufficient evidence that the
    defendant knew Combs was armed with the stun gun.   Cellular
    telephone records indicated that the defendant had been in
    contact with Combs on the day before and at relevant times on
    the day of the robbery, suggesting that he had played a
    significant role in planning to rob Jones.   The defendant knew
    that Jones was a large man and that Jones intended to take part
    in a drug deal.   A rational jury therefore reasonably could
    infer that the defendant and Combs planned to use a weapon to
    overpower Jones when he arrived in Springfield.   See
    Commonwealth v. Housen, 
    458 Mass. 702
    , 708 (2011) (evidence
    sufficient to support inference that defendant knew codefendant
    was armed where victim was drug dealer unlikely to submit to
    robbery without show of superior force).   Even if the defendant
    had been unaware in advance that Combs would be armed, however,
    he told police that he saw Combs using the stun gun on Jones
    before he drove Jones to Bloomfield.   The defendant's knowledge
    of the use of the weapon and continued participation in the
    robbery thereafter were sufficient to implicate him as a joint
    venturer.   Compare Commonwealth v. Norris, 
    462 Mass. 131
    , 140
    8
    As discussed below, it also would have been reasonable to
    infer that a ligature ultimately was used to cause Jones's
    death.
    12
    (2012) (evidence sufficient to conclude that defendant was joint
    venturer in armed robbery where defendant continued to
    participate in robbery after learning codefendant was armed).
    Although defense counsel emphasizes that money Jones
    previously had hidden in his home was not taken during the
    alleged robbery, the defendant returned to work on January 22,
    2010, with what appeared to be a windfall profit.   The money he
    showed off to his coworkers reasonably could be inferred to have
    been taken from Jones, because the defendant told police that he
    had lured Jones to Springfield with the promise that he could
    purchase drugs there.
    ii.   Extreme atrocity or cruelty.   The defendant also
    argues that the evidence was insufficient to convict him as a
    joint venturer of murder in the first degree on a theory of
    extreme atrocity or cruelty because no evidence showed that he
    participated in the strangulation of Jones by ligature, or that
    Jones's murder was extremely atrocious or cruel.
    "The critical question with respect to whether the evidence
    was sufficient to warrant a finding that a defendant is guilty
    of murder in the first degree as a joint venturer on the
    theor[y] of . . . extreme atrocity or cruelty is whether the
    defendant was present at the scene of the murder, with the
    knowledge that another intends to commit a crime or with intent
    to commit the crime and by agreement was willing and available
    13
    to assist if necessary."   Commonwealth v. Deane, 
    458 Mass. 43
    ,
    50 (2010), citing Commonwealth v. Phillips, 
    452 Mass. 617
    , 633
    (2008).   The Commonwealth need not prove, however, "exactly how
    a joint venturer participated in the murder[], or which of the
    two did the actual killing."     Deane, supra at 50-51.
    Murder on a theory of extreme atrocity or cruelty only
    requires a mens rea of malice.    See Commonwealth v. Garcia, 
    470 Mass. 24
    , 32 (2014).   "Malice is defined in these circumstances
    as an intent to cause death, to cause grievous bodily harm, or
    to do an act which, in the circumstances known to the defendant,
    a reasonable person would have known created a plain and strong
    likelihood that death would follow."     
    Id.,
     quoting Commonwealth
    v. Szlachta, 
    463 Mass. 37
    , 45-46 (2012).    A defendant does not
    have to have known that his or her joint venturer possessed the
    murder weapon.   See Commonwealth v. Pov Hour, 
    446 Mass. 35
    , 42
    (2006).   Furthermore, he or she need not have known or intended
    that the murder be extremely atrocious or cruel.    See Garcia,
    supra.
    Viewing the evidence in the light most favorable to the
    Commonwealth, a rational juror reasonably could have concluded
    that the defendant was present at the scene of Jones's murder.
    The defendant told police he had escorted Jones into the house
    on Florida Street to introduce Jones to Combs.    Other evidence
    indicated that that the defendant had been in physical contact
    14
    with Jones in the Saturn:   both the defendant's and Jones's DNA
    profiles were present on the latex glove fingertip that was
    found on the floor in the back seat of the vehicle.    In
    addition, when Jones was found lying on his stomach across the
    back seat of the vehicle, his feet were pressed up against the
    door.    Given Jones's size, it would be reasonable to infer that
    he had been put into the vehicle forcibly with the defendant's
    help, and that he was at least incapacitated by the stun gun if
    not already strangled when he was put there.
    While "[t]he line that separates mere knowledge of unlawful
    conduct and participation in it, is 'often vague and
    uncertain,'" Norris, 462 Mass. at 140, quoting Commonwealth v.
    Longo, 
    402 Mass. 482
    , 487 (1988), the evidence also allowed for
    the reasonable conclusion that the defendant either knew that
    Combs intended to kill Jones or himself intended to cause Jones
    death or grievous bodily harm.   Jones knew only the defendant,
    not Combs; the defendant thus had a greater incentive than Combs
    to ensure that Jones would not retaliate.    Furthermore, it is
    evident that the defendant wore latex gloves while in contact
    with Jones, inferably to avoid leaving fingerprints.    In
    addition, the defendant's changing story to police and others
    regarding what happened on the day of Jones's death allowed a
    reasonable inference that the defendant was conscious of his
    guilt.
    15
    There was also sufficient evidence from which a jury could
    have concluded that Jones's death was extremely atrocious or
    cruel.   To determine that a homicide was committed with extreme
    atrocity or cruelty, a jury must consider several factors:      a
    defendant's or joint venturer's "indifference to or taking
    pleasure in the victim's suffering, consciousness and degree of
    suffering of the victim, extent of physical injuries, number of
    blows, manner and force with which delivered, instrument
    employed, and disproportion between the means needed to cause
    death and those employed."   Commonwealth v. Cunneen, 
    389 Mass. 216
    , 227 (1983).   While a jury must find at least one of the
    Cunneen factors to support a verdict of extreme atrocity or
    cruelty, see Commonwealth v. Blackwell, 
    422 Mass. 294
    , 299
    (1996), they need not be unanimous with respect to which factor
    or factors they determine to be applicable.   See Commonwealth v.
    Morganti, 
    455 Mass. 388
    , 407 (2009), S.C., 
    467 Mass. 96
     (2014).
    The jury heard testimony that Jones was assaulted
    repeatedly with a stun gun and eventually strangled to death.
    They also heard that it would have taken eight to ten seconds of
    sustained strangulation to cause Jones to lose consciousness,
    and several more minutes for strangulation to cause death, and
    that his injuries were consistent with terminal seizure
    activity, in which a person being strangled twitches and bites
    his lips as he dies.   See Commonwealth v. Linton, 
    456 Mass. 534
    ,
    16
    546-547 (2010) (reasonable jury could find victim's homicide by
    means of manual strangulation was extremely atrocious or cruel).
    This evidence would have allowed the jury reasonably to apply
    several of the Cunneen factors.9
    b.   Speedy trial.   The defendant argues that his motion to
    dismiss on speedy trial grounds was incorrectly denied, because
    his trial was delayed repeatedly for over one year.    Pursuant to
    Mass R. Crim. P. 36 (b), as amended, 
    422 Mass. 1503
     (1996), a
    defendant is entitled to dismissal if a trial does not take
    place within twelve months of the defendant's arraignment.10
    However, a period of delay does not count toward the twelve-
    month maximum if a defendant acquiesced in or benefited from it.
    See Commonwealth v. Roman, 
    470 Mass. 85
    , 92-93 (2014).
    We consider the defendant's motion to dismiss on speedy
    trial grounds de novo.    See Commonwealth v. Rodgers, 
    448 Mass. 538
    , 540 (2007).    "For purposes of a rule 36 calculation of
    excludable periods, the docket and the clerk's log are prima
    facie evidence of the facts recorded therein."    Roman, supra
    at 93.    Because 518 days passed between October 4, 2011, the
    9
    Furthermore, the defendant told police that, when he left
    Jones in the parking lot, he was still making "little noises."
    If the jury believed this statement, they reasonably could have
    inferred from it that the defendant was indifferent to Jones's
    suffering.
    10
    See Mass. R. Crim. P. 2 (b) (15), as amended, 
    397 Mass. 1226
     (1986) (defining "return day" as date of arraignment).
    17
    date the defendant was arraigned, and March 5, 2013, the date he
    filed his motion to dismiss, the defendant has established a
    prima facie case that his speedy trial right was violated.11       The
    Commonwealth therefore has the burden of showing that at least
    152 days of the delay should not count toward the twelve-month
    maximum.12    See id. at 92 (shifting burden to Commonwealth to
    justify delay after defendant establishes prima facie case).
    That burden has been met in this case.    "When a defendant
    has agreed to a continuance, or has not entered an objection to
    delay, he will be held to have acquiesced in the delay."       Barry
    v. Commonwealth, 
    390 Mass. 285
    , 298 (1983).    See Roman, supra
    at 93.    Here, it is evident from the docket and the clerk's log
    that the defendant and the Commonwealth jointly requested to
    continue the pretrial hearing date from March 14, 2012, to
    April 23, 2012 -- a delay of forty-one days.     They also agreed
    to extend the deadline for filing pretrial motions from April
    30, 2012, to August 13, 2012 -- a delay of an additional 106
    days.     Moreover, they jointly requested to continue the trial
    date from December 3, 2012, the date they had jointly proposed
    in the pretrial conference report, to April 1, 2013.     The

    See Mass R. Crim. P. 36 (b) (3), as amended, 
    422 Mass. 1503
     (1996) ("In computing any time limit other than an excluded
    period, the day of the act or event which causes a designated
    period of time to begin to run shall not be included").
    12
    The year 2012 was a leap year.
    18
    defendant thus had acquiesced to an additional period of delay
    of at least 120 days when, on March 5, 2013, he filed his motion
    to dismiss on speedy trial grounds.   Other delays may also have
    been permitted, but we need not address them here.   The delays
    described above already substantially exceed the number of days
    the Commonwealth must justify.
    c.   Defendant's statements to police.   As noted, police
    audiorecorded both of their interviews of the defendant without
    his knowledge, using a pen recorder.13   After the defendant filed
    an unsuccessful motion in limine to exclude the interviews from
    evidence, the contents of the interviews were admitted in
    several ways at trial, over repeated objection.   The officer who
    recorded the interviews read excerpts from the transcripts of
    those recordings to the jury; she also read the several written
    statements that the defendant signed in her presence.14   The
    transcript excerpts and written statements also were admitted in
    evidence separately.   Furthermore, the unredacted recordings of
    13
    The record does not indicate whether the defendant was
    informed of the Miranda rights prior to either interview. The
    defendant did not, however, move to suppress the statements on
    Miranda grounds. He requested and received a humane practice
    instruction at trial.
    14
    The officer also testified regarding her perception of
    the defendant's demeanor during the interviews, including her
    belief that the defendant was "relaxed" and not under the
    influence of drugs or alcohol.
    19
    the interviews were marked as exhibits, and redacted recordings
    were available to the jury upon request during deliberations.
    The defendant argues that the contents of his oral
    statements to police should not have been admitted,15 and
    contests the manner in which they were admitted.    For the
    reasons that follow, we conclude that the judge did not abuse
    his discretion either in the admission of the statements
    themselves or in the ways they were admitted.
    i.   Admission of statements.   The recordings of the
    defendant's statements to police were not complete -- the
    officer who was carrying the recording device left the interview
    room at least once during the second interview.    Accordingly,
    the defendant contends that his statements should not have been
    admitted because the recordings were incomplete, and because
    they were recorded without his knowledge or consent.    Reviewing
    the admission of the defendant's statements for abuse of
    discretion, however, we discern no error.16   See Commonwealth v.
    Valentin, 
    420 Mass. 263
    , 270 (1995), S.C., 
    470 Mass. 186
     (2014).
    15
    Although the defendant preserved objections to the
    admission of his written, signed statements to police, he does
    not raise these arguments on appeal. We discern no error in
    their admission.
    16
    In his order denying the motion in limine, the trial
    judge erroneously stated that the audiorecordings were complete
    recordings of the defendant's interviews with police.
    Nonetheless, we conclude that the statements were properly
    admitted. See Commonwealth v. Bennett, 
    414 Mass. 269
    , 271
    20
    Although the lack of a complete recording of a defendant's
    statements to police at times may be problematic, completeness
    is not a prerequisite for admission.   See Commonwealth v.
    DiGiambattista, 
    442 Mass. 423
    , 449 (2004).    Instead, "a
    defendant whose interrogation has not been reliably preserved by
    means of a complete electronic recording should be entitled, on
    request, to a cautionary instruction concerning the use of such
    evidence."   Id. at 447.   Such an instruction was given in this
    case:   the jury were told to consider the defendant's alleged
    statements with "great care and caution."    Furthermore, the fact
    that the recordings were made without the defendant's knowledge
    was not a basis to exclude them from the evidence in this case.
    Although secret recordings sometimes may be misleading, there is
    no indication that the defendant would have acted differently
    had he been aware that he was being recorded.     To the contrary,
    he signed several written statements that memorialized the
    versions of what had happened that he related to police.
    The defendant also argues, for the first time on appeal,
    that the recordings were made in violation of G. L. c. 272,
    § 99, the Massachusetts wiretap statute.     General Laws c. 272,
    § 99, provides a suppression remedy in Massachusetts for the
    (1993), citing Aetna Cas. & Sur. Co. v. Continental Cas. Co.,
    
    413 Mass. 730
    , 734 (1992) ("We decline . . . to rest our
    conclusion on the ground on which the trial judge relied but
    reach the same result for a different reason").
    21
    unlawful interception of communications by police.
    Communications intercepted by Federal law enforcement officers
    are explicitly exempted from that remedy if the officers are
    "acting pursuant to authority of the laws of the United States
    and within the scope of their authority."   G. L. c. 272,
    § 99 D 1 c.   The defendant argues that, because the statute does
    not contain a similarly explicit exemption for law enforcement
    officers of another State acting pursuant to that State's laws,
    the recordings at issue here should have been suppressed.
    Nonetheless, "[t]he legality of the procedures employed by
    the police forces of other States operating in their own
    jurisdiction is governed by the law of that jurisdiction."
    Commonwealth v. Scoggins, 
    439 Mass. 571
    , 578 (2003).   The
    recordings at issue here were made by Connecticut police
    officers in Connecticut more than one year before Massachusetts
    law enforcement officers became involved in the investigation.
    Nothing in the record suggests that the recordings were made
    with the knowledge or at the behest of the Commonwealth.
    Because the police are permitted to record interviews secretly
    under Connecticut law, no suppression remedy is available.     See
    Conn. Gen. Stat. § 53a-187(b).   See also State v. DelVecchio,
    
    191 Conn. 412
    , 430-432 (1983) (no suppression remedy under
    Connecticut Constitution for secretly recorded statements).
    22
    ii.   Manner of admission.   The defendant argues that the
    interview transcripts were presented improperly to the jury "in
    lieu" of the recordings rather than as an interpretive
    supplement to them.   Relatedly, he argues that it was error to
    admit redacted versions of the recordings after the close of
    evidence, rather than through a witness, and before he had had a
    chance to review them.
    Properly authenticated transcripts of recordings, however,
    may be "offer[ed] . . . in evidence or for identification as an
    aid to the finder of fact."    Commonwealth v. Portillo, 
    462 Mass. 324
    , 327 (2012).   Here, the transcripts that were read in
    evidence had been prepared by an official court reporter at the
    defendant's request.17   In addition, there was no error in the
    eventual admission of the redacted recordings.   The unredacted
    recordings previously had been authenticated and marked as an
    exhibit; it is evident that the redacted recordings were
    admitted simply to reflect redactions to the transcript that had
    been agreed to before trial.   See Commonwealth v. Rogers, 
    459 Mass. 249
    , 268, cert. denied, 
    132 S. Ct. 813
     (2011) (admission
    of cumulative evidence "fall[s] within the judge's discretion").
    In any event, the record does not indicate that the jury ever
    asked to listen to the recordings, and the defendant does not
    17
    The Commonwealth also had a transcription of the
    recordings prepared by a court reporter, but agreed to use the
    defendant's version.
    23
    suggest otherwise.     Any error in their admission therefore would
    have been harmless.
    d.   Substitute medical examiner.    Before trial, the
    Connecticut medical examiner who conducted Jones's autopsy and
    prepared the autopsy report, Dr. Frank Evangelista, was indicted
    in Massachusetts for perjury and obstruction of justice in an
    unrelated matter.18     Although Evangelista was available to
    testify, the Commonwealth opted instead to present testimony
    from a substitute medical examiner, Dr. Joann Richmond, a
    retired forensic pathologist, regarding the cause of Jones's
    death.    The defendant repeatedly objected to the admission of
    this testimony.19     Nonetheless, Richmond ultimately was allowed
    to testify regarding the nature of Jones's injuries, and to
    offer her opinion concerning the cause of his death.
    Evangelista's autopsy report was not offered or admitted in
    evidence.
    On appeal, the defendant argues that the admission of
    testimony by a substitute medical examiner, despite the
    18
    The district attorney for the Plymouth district brought
    those indictments.
    19
    The defendant filed a motion in limine and a supplemental
    motion in opposition to the Commonwealth's motion to permit
    testimony by a substitute medical examiner. In addition, the
    defendant objected to the admission of the testimony during
    pretrial hearings, and moved to strike the testimony. The
    defendant also objected to the substitute examiner's opinion
    testimony regarding the cause of the victim's death.
    24
    availability of the original examiner, violated his
    constitutional confrontation rights.   In addition, he argues
    that the substitute testimony should not have been admitted
    because it was not scientifically reliable.    He also contends
    that the jury should have been given a missing witness
    instruction to account for the absence of Evangelista's
    testimony.
    i.   Right of confrontation.   The Sixth Amendment to the
    United States Constitution and art. 12 of the Massachusetts
    Declaration of Rights both provide criminal defendants with the
    right to be confronted with the witnesses against them.    Neither
    the fact that the original examiner was available to testify nor
    the contents of the substitute examiner's testimony, however,
    violated that right.
    The defendant argues that the Commonwealth's use of a
    substitute medical examiner in this case impermissibly prevented
    him from calling Evangelista's credibility into question on
    cross-examination.   Nonetheless, "[w]e have never stated that a
    substitute medical examiner may not testify to his or her own
    opinions unless the medical examiner who performed the autopsy
    is shown to be unavailable, nor is there any rule of criminal
    procedure setting forth such a requirement."    Commonwealth v.
    Reavis, 
    465 Mass. 875
    , 881-882 (2013).   Because the Commonwealth
    did not offer testimonial out-of-court statements by Evangelista
    25
    in this case, the defendant had no constitutional right to
    confront those statements.
    A substitute medical examiner may not testify to facts in
    an autopsy report if that report has not been admitted in
    evidence.   See Commonwealth v. Durand, 
    457 Mass. 574
    , 584-585
    (2010), citing Commonwealth v. Nardi, 
    452 Mass. 379
    , 391 (2008).
    A substitute examiner may, however, "offer an opinion on the
    cause of death, based on his [or her] review of an autopsy
    report by the medical examiner who performed the autopsy and his
    review of the autopsy photographs, as these are documents upon
    which experts are accustomed to rely, and which are potentially
    independently admissible through appropriate witnesses."
    Reavis, supra at 883, citing Commonwealth v. Emeny, 
    463 Mass. 138
    , 145 (2012).   That is what happened here.
    As noted, Evangelista's autopsy report as to Jones was not
    offered against the defendant, and Richmond did not testify to
    facts it contained.    Rather, she based her testimony on her
    independent understanding as a pathologist of both the report
    and photographs of Jones's injuries from the crime scene and
    autopsy.    For example, she testified that the photographs showed
    petechial hemorrhaging in Jones's eyes, as well as bleeding and
    bruising injuries that were consistent with terminal seizure-
    like activity.   In addition, she testified that, in her opinion,
    Jones died of "ligature strangulation."   Furthermore, the
    26
    defendant had an opportunity to cross-examine Richmond, and
    questioned her vigorously concerning the bases of her opinions.20
    See Commonwealth v. Greineder, 
    464 Mass. 580
    , 594-595, cert.
    denied, 
    134 S. Ct. 166
     (2013) (noting that confrontation right
    protects opportunity for meaningful cross-examination).    No more
    was constitutionally required.
    ii.   Scientific reliability of substitute testimony.    The
    defendant argues that Richmond's testimony was scientifically
    unreliable because she did not perform Jones's autopsy herself.
    The trial judge, however, declined to exclude Richmond's
    testimony on this ground, and the defendant's objection at trial
    similarly was overruled.   In light of our conclusion above that
    there was no constitutional error, we review those
    determinations for abuse of discretion.   See Commonwealth v.
    Matthews, 
    450 Mass. 858
    , 871 (2008), citing Canavan's Case, 
    432 Mass. 304
    , 311 (2000).
    The testimony of a scientific expert witness is not
    admissible if the reasoning or methodology underlying that
    testimony is not scientifically valid or cannot be applied
    properly to the facts at issue in a given case.   See
    20
    On cross-examination, the substitute medical examiner
    acknowledged the deficiencies of substitute testimony: she
    noted that as the primary examiner she would have personally
    examined the victim's body, and not simply relied on pictures
    from the autopsy, and would also have had the ability to make
    independent measurements and compare the width of a shoelace
    found at the crime scene to the marks on the defendant's neck.
    27
    Commonwealth v. Lanigan, 
    419 Mass. 15
    , 25-26 (1994), citing
    Daubert v. Merrell Dow Pharms., Inc., 
    509 U.S. 579
    , 592-593
    (1993).    See also Commonwealth v. Barbosa, 
    457 Mass. 773
    , 783
    (2010), cert. denied, 
    563 U.S. 990
     (2011) (listing foundational
    requirements for admission of expert testimony in criminal
    case).    A judge need not conduct an extensive inquiry into the
    validity of an expert's testimony if, on the other hand, "the
    expert's methodology has previously been accepted as reliable in
    the relevant field."    Commonwealth v. Sliech-Brodeur, 
    457 Mass. 300
    , 327 (2010), citing Commonwealth v. Shanley, 
    455 Mass. 752
    ,
    763 n.15 (2010).
    The witness's status as a substitute examiner was not a
    sufficient basis to exclude her testimony.    Richmond may have
    been less well positioned to assess the cause of Jones's death
    than the medical examiner who conducted his autopsy, but she
    applied accepted methods and understandings of forensic medicine
    in her independent assessment of the photographs of Jones's
    injuries at trial.    The judge therefore did not abuse his
    discretion in determining that Richmond's testimony would be a
    reliable scientific opinion.
    iii.    Missing witness instruction.   A missing witness
    instruction permits the jury, "if they think reasonable in the
    circumstances, [to] infer that that person, had he [or she] been
    called, would have given testimony unfavorable to the party."
    28
    Commonwealth v. Saletino, 
    449 Mass. 657
    , 668 (2007), quoting
    Commonwealth v. Anderson, 
    411 Mass. 279
    , 280 n.1 (1991).       Such
    an instruction may be appropriate when a party "'has knowledge
    of a person who can be located and brought forward, who is
    friendly to, or at least not hostilely disposed toward, the
    party, and who can be expected to give testimony of distinct
    importance to the case,' and the party, without explanation,
    fails to call the person as a witness."      Saletino, supra at 667,
    quoting Anderson, 
    supra
     at 280 n.1.     The instruction should be
    provided "only in clear cases, and with caution."     Saletino,
    supra at 668, quoting Commonwealth v. Figueroa, 
    413 Mass. 193
    ,
    199 (1992), S.C., 
    422 Mass. 72
     (1996).     If a judge determines
    that a missing witness instruction is not appropriate, counsel
    are not permitted to argue the issue during closing.     Saletino,
    supra at 670.    That determination is reviewed for abuse of
    discretion.     See id. at 667.   See also L.L. v. Commonwealth, 
    470 Mass. 169
    , 185 n.27 (2014).
    The judge denied the defendant's request for a "missing
    witness" instruction with respect to Evangelista, and prohibited
    him from arguing the issue to the jury.     The judge determined
    that the Commonwealth had a legitimate tactical reason for not
    calling Evangelista -- it wished to avoid relying on a witness
    who was under indictment by another district attorney's office.
    29
    That determination was not "outside the range of reasonable
    alternatives."    See L.L., supra.
    e.    Admission of cellular telephone records.   At trial,
    CSLI for Combs's and the defendant's cellular telephones was
    admitted in evidence.    Call records for Combs's, Jones's, and
    the defendant's telephone numbers were also admitted.    The
    defendant argues for the first time on appeal that the call
    records and CSLI were not obtained pursuant to search warrants,
    in violation of his rights under the Fourth Amendment to the
    United States Constitution and art. 14 of the Massachusetts
    Declaration of Rights, and in violation of the Federal stored
    communications act, 
    18 U.S.C. § 2703
     (2012).    He contends that
    his trial counsel was ineffective for failing to object to their
    admission on these bases.21   In addition, he challenges, as he
    did at trial, the qualifications of an expert witness who
    testified regarding the call records.
    We discern no error in the admission of the CSLI and call
    records.    Contrary to the defendant's contention, the record
    shows the call records were obtained pursuant to search warrants
    in Connecticut.    Thus, there was no violation of the relevant
    21
    The defendant's trial counsel objected to the admission
    of the cellular site location information (CSLI) data only on
    the ground that the version of the data she had been sent before
    trial was formatted slightly differently from the version that
    was admitted.
    30
    constitutional and statutory requirements, and his trial counsel
    was not ineffective for failing to raise these arguments.
    Furthermore, the judge did not abuse his discretion in
    allowing a sales manager at the defendant's cellular telephone
    service provider to testify regarding the contents of call
    records.   See Commonwealth v. Frangipane, 
    433 Mass. 527
    , 533,
    537 (2001) (reviewing preserved objection to admission of expert
    testimony for abuse of discretion).     Although an expert witness
    may not testify to matters beyond his or her area of expertise
    or competence, id. at 533, the sales manager had been employed
    by the service provider for fifteen years and had been trained
    in reviewing customers' bills to interpret the type of call
    record information about which he testified.    We discern no
    abuse of discretion in allowing this testimony.22
    f.    Admission of DNA evidence.   The swab used for
    extracting raw DNA from the latex glove fingertip found in
    Jones's vehicle was consumed in its entirety before the police
    arrested the defendant.   Although the defendant asked for DNA
    material for retesting during discovery, he was told repeatedly
    that no material existed.   On April 24, 2013, however, days
    22
    The defendant's contention that the particular call
    records and CSLI introduced in this case are not business
    records is also baseless. See Smith v. Maryland, 
    442 U.S. 735
    ,
    744-745 (1979) (treating telephone call records as business
    records); Commonwealth v. Augustine, 
    467 Mass. 230
    , 232 (2014)
    (treating CSLI as business record).
    31
    before the trial was scheduled to begin, he learned for the
    first time that DNA material extracted from the swab remained
    available for further testing.   Although the judge indicated a
    willingness to continue the trial, the defendant neither
    performed such testing before the scheduled trial date nor
    sought a continuance to do so.   Instead, he sought
    unsuccessfully to exclude the results of the testing that had
    already been done on the swab.
    The defendant argues that the Commonwealth violated its
    duty to preserve exculpatory evidence because he was unable to
    test raw DNA material from the swab independently, and because a
    defense expert was unable to observe the extraction process to
    ensure that proper protocols were followed.   A prosecutor's
    preservation duty, however, only "extend[s] to material and
    information in the possession or control of members of his [or
    her] staff and of any others who have participated in the
    investigation or evaluation of the case and who either regularly
    report or with reference to the particular case have reported to
    his [or her] office."   Commonwealth v. Daye, 
    411 Mass. 719
    , 734
    (1992), quoting Commonwealth v. St. Germain, 
    381 Mass. 256
    , 261
    n.8 (1980).   Here, the prosecutor had no control over the
    32
    testing of the swab at the time the raw DNA was consumed.23
    Thus, the preservation duty did not apply.
    A defendant "'may be independently entitled to a remedy' of
    exclusion if the loss or destruction of evidence was due to the
    bad faith or reckless acts of the Commonwealth."    Commonwealth
    v. Sanford, 
    460 Mass. 441
    , 447 (2011), citing Commonwealth v.
    Williams, 
    455 Mass. 706
    , 718 (2010).    Such a remedy is not,
    however, available in this case.   Although the defendant
    received late notice of the availability of extracted DNA
    material for testing, the exhaustion of the raw DNA material on
    the swab was not due to that delay.    Nor was the defendant
    prevented from testing the extracted DNA material that remained
    available.
    g.   Relief pursuant to G. L. c. 278, § 33E.   We have
    examined the record carefully pursuant to our duty under G.L.
    23
    The swab used for extracting DNA from the latex glove
    fingertip found in Jones's vehicle was first tested by the DNA
    unit of the Connecticut forensic laboratory on June 21, 2010.
    However, a scientist at the laboratory eventually determined
    that the "typing kit" initially used on the swab may have been
    "substandard or potentially compromised," requiring retesting.
    Because retesting would extract all remaining raw DNA material
    on the swab, the scientist contacted the Bloomfield,
    Connecticut, police department to determine whether a suspect
    had been arrested who should be given an opportunity to observe
    the testing. She was told that there was a person of interest
    in the case, but that no arrests had been made. On January 20,
    2011, she retested the swab. As noted above, Massachusetts
    State police did not assume an active role in the investigation
    until February, 2011, and the defendant was not arraigned in
    Massachusetts until October, 2011.
    33
    c. 278, § 33E, and discern no basis on which to grant the

    Judgments affirmed.

    The defendant asks that we vacate his conviction of armed
    robbery because it is a lesser included offense of, and
    therefore merges with, the murder conviction. This request does
    not account for the defendant's conviction of murder on the
    theory of extreme atrocity or cruelty. "[W]here, as here, the
    conviction of murder is based on a theory in addition to the
    theory of felony-murder, the conviction of the underlying felony
    stands." Commonwealth v. Brum, 
    441 Mass. 199
    , 200 n.1 (2004),
    citing Commonwealth v. Pennellatore, 
    392 Mass. 382
    , 390 (1984).
