    GANTS, C.J.     On May 11, 2010, the defendant, Larry
    Housewright, pointed a weapon at a second-story window where a
    witness in his friend's criminal case was standing, and fired as
    the truck in which he was a passenger drove away.    A District
    Court jury convicted the defendant of intimidating a witness,
    carrying a firearm without a license, discharging a firearm
    within 500 feet of a building, and assault by means of a
    dangerous weapon.   On appeal, the defendant claims that (1) the
    judge abused his discretion in allowing the Commonwealth to
    present a witness's prior recorded testimony without sufficient
    proof of the witness's unavailability; (2) the judge abused his
    discretion in admitting two photographs of a handgun that looked
    like the unrecovered handgun fired by the defendant; and (3) the
    judge erred in denying the defendant's motion for a required
    finding of not guilty because the evidence was insufficient to
    support the conviction of unlawful carrying of a firearm, where
    no reasonable jury could find beyond a reasonable doubt that the
    defendant's handgun was capable of discharging a bullet.
    Although we find no error in the admission of the
    photographs or in the denial of the motion for a required
    finding of not guilty, we conclude that the judge abused his
    discretion in determining that the Commonwealth's witness was
    unavailable to testify based solely on a doctor's four-sentence
    letter that listed her medical conditions and opined that the
    3
    stress of testifying in court "might" be detrimental to the
    witness's health.   Because the admission of the witness's prior
    recorded testimony without an adequate showing of the witness's
    unavailability violated the defendant's constitutional right to
    confront the witness, and because the error was not harmless
    beyond a reasonable doubt, we vacate the convictions and remand
    for a new trial.
    Background.    We briefly describe the evidence at trial,
    reserving discussion of the evidence that is relevant to the
    issues raised on appeal.
    In 2010, Doris Williams owned a two-family house in New
    Bedford, and lived in the first-floor apartment; Kim Sivertsen
    and Aaron Tobia lived together on the second floor.    In February
    of that year, Williams's grandson, Matthew Borges,1 was charged
    with breaking and entering the second-floor apartment.    On May
    5, Sivertsen and Tobia attended a pretrial conference in the
    case against Matthew, during which Matthew made threatening
    gestures aimed at them, such as drawing his finger across his
    neck, pointing his finger in the form of a gun, and hitting his
    fist against his other hand.    When Sivertsen left the court
    house, she saw a white truck with distinctive features pull up
    in front of the court house and pick up Matthew and his brother,
    1
    Because Matthew Borges and various witnesses share the
    same surname, we will refer to them by their first names.
    4
    Joshua Borges.    Because the truck's windows were tinted, she
    could not see the faces of any other people in the truck.
    On May 11, Sivertsen was returning to her apartment at
    approximately 3:15 P.M. when she saw the same white truck from
    the court house parked on the street outside her apartment, with
    a woman in the driver's seat and two passengers.    Sivertsen
    knocked on Williams's front door to ask if she was expecting
    anyone.    Williams, whose prior recorded testimony was presented
    at trial, stated that when she opened the door, she saw the
    defendant open the passenger side door and say, "Hi Grandma."
    Williams had known the defendant since he was a child; her
    grandson, Matthew, and the defendant were childhood friends, and
    the defendant always called her "Grandma."    She asked the
    defendant what he was doing in the neighborhood, and he
    responded, "I'm waiting for someone."
    Sivertsen testified that the defendant shouted that he was
    the one that picked up Matthew from the court house and that he
    was there to pick up "Mikey."2    The defendant then told
    Sivertsen, "Tell your boyfriend I have something for him," and
    pulled out a small, silver gun and showed it to her.    After
    Sivertsen said she was going to call 911, the truck began moving
    away, but as it was leaving, the defendant pointed the gun out
    of the passenger's side window and fired it at the second-floor

    window where Tobia was standing.    Williams had already reentered
    her home, and "didn't see anything" related to the shooting.3
    The police were unable to locate any shell casings, bullets,
    bullet holes, or other property damage.
    Williams's son, Stephen Borges, who was Matthew's uncle,
    was in the cellar of Williams's apartment at the time of the
    incident.    From the cellar, he heard "a gunfire go off," which
    caused him to run outside.    He saw the white truck leave and
    recognized someone who "hung around with Matthew."    He got into
    his own vehicle and followed the white truck until it parked,
    where he saw Matthew and the defendant get out.    A day or two
    after the incident, Stephen returned to the area where the white
    truck parked and saw it again.    He recorded the license plate
    number and later gave that number, the name of the defendant,
    and the location of the white truck to Williams.
    On May 12, Sivertsen provided Detective William Sauvé with
    a physical description of the assailant, which he used to
    assemble a six-photograph sequential array that included the
    defendant.   When Sivertsen viewed the array, she did not
    identify the defendant and said she was eighty per cent certain
    3
    Williams initially testified at the prior recorded
    hearing, "He only fired once. And he aimed for the second
    floor." But she then clarified that she did not actually see
    the shot. She only "heard it." It was Aaron Tobia who told her
    that the sound was gunfire and that "the guy pointed [the gun]
    up to the window."
    6
    that one of the other photographs depicted the perpetrator.4
    Tobia viewed the same set of photographs and, despite stating he
    was ninety per cent confident, chose not to make an
    identification.5
    A couple days later, Williams went to the police station
    with her daughter, Laurie Borges, to view the photographic
    array.6   They viewed the array together, and Williams picked a
    photograph of the defendant, saying it looked like the
    assailant, but she was not positive because the person in the
    photograph had a beard, but she remembered the defendant best
    without facial hair.    Detective Sauvé then printed an older
    photograph of the defendant, where he did not have facial hair,
    and displayed it to Williams and Laurie, who both said that it
    showed the defendant.
    4
    At trial, when showed the photographic array again (in
    simultaneous form), Kim Sivertsen could not identify which
    photograph she originally thought showed the perpetrator, but
    she identified the defendant in court as the man in the
    passenger seat and stated that she was one hundred per cent
    confident in her identification. She explained that the
    defendant's large stature is his most identifying feature, which
    is not well depicted in a photograph.
    5
    At trial, Tobia identified the defendant in-court and
    explained that he had been unable to be fully confident in
    making an identification without seeing the person in front of
    him, as photographs only show the face, and the perpetrator was
    a big person.
    6
    Laurie Borges was not an eyewitness to the events on May
    11, 2010.
    7
    While meeting with Detective Sauvé, Williams also provided
    the information that she received from her son, Stephen:      the
    white truck's license plate number, the defendant's name, and
    the location where her son found the white truck.    Detective
    Sauvé found the white truck at the location, obtained an arrest
    warrant, and arrested the defendant.    At the time of the arrest,
    the defendant was living with his girlfriend, Melissa Gomes, at
    the address where both Stephen and Detective Sauvé had observed
    the truck.
    At trial, the defendant, through the testimony of his
    cousin, Eliot Spooner, presented an alibi that he was being
    driven to St. Luke's Hospital when the shooting occurred.
    Spooner testified that the defendant and he were working at a
    farm in Rochester on May 11, and at approximately 2:45 P.M.,
    Spooner injured his finger while splitting wood.     Spooner and
    the defendant called Gomes, who picked them up at around 3:15
    P.M. to drive them to the hospital.    They arrived at the
    hospital at approximately 3:50 P.M.    At the hospital, the
    defendant stayed with Spooner for at least one-half hour to one
    hour while Spooner waited to see the doctor.
    Discussion.   1.   Prior recorded testimony.    On the first
    day of trial, the Commonwealth filed a motion in limine to admit
    Williams's prior testimony from the defendant's pretrial
    detention hearing, conducted pursuant to G. L. c. 276, § 58A, on
    8
    May 21 and 24, 2010.     The Commonwealth argued that Williams was
    unavailable due to illness and that her testimony fell within
    the hearsay exception for prior recorded testimony of an
    unavailable declarant.    See Mass. G. Evid. § 804(b)(1) (2014)
    (hearsay exception, if declarant is unavailable, for testimony
    given at another trial or hearing, where party against whom
    testimony is offered had opportunity and similar motive to
    develop testimony by direct, cross-, or redirect examination).
    a.   Unavailability due to illness or infirmity.     To show
    that Williams was unavailable to testify at trial, the
    Commonwealth relied on her returned summons, which noted that
    she would not be able to attend the trial because she was "under
    doctor's care," and on a letter from her doctor, which declared:
    "Doris Williams is a 74 year old patient under my care for:
    cardiomyopathy, coronary artery disease, peripheral
    vascular disease, arthritis and angina. It is my medical
    opinion that the stress of testifying in court might be
    detrimental to her health. I urge you to exclude her from
    your witness list."
    The letter also provided the doctor's office telephone number
    "[i]f you require additional information."
    The defendant objected to the admission of Williams's prior
    testimony on various grounds, including the insufficiency of the
    doctor's letter to establish unavailability.    The judge
    overruled the objection and allowed the motion to admit
    Williams's prior recorded testimony, noting that "if she's under
    9
    a physical infirmity that puts her health at risk for
    testifying, I think that would be a sufficient basis to find her
    unavailable."
    On appeal, the defendant argues that the admission of
    Williams's prior testimony violated his right to confront the
    witness under the Sixth Amendment to the United States
    Constitution and art. 12 of the Massachusetts Declaration of
    Rights.7   We address initially the defendant's claim that the
    Commonwealth did not sufficiently prove that the witness was
    unavailable.8
    "In [Crawford v. Washington, 
    541 U.S. 36
    , 57-59 (2004)],
    the United States Supreme Court held that testimonial out-of-
    court statements made by a declarant who is not a witness at
    trial are inadmissible under the confrontation clause of the
    Sixth Amendment, unless the declarant is unavailable to testify
    7
    The defendant does not argue that the right of
    confrontation under art. 12 of the Massachusetts Declaration of
    Rights affords greater protection than the Sixth Amendment of
    the United States Constitution, so we do not discuss these
    provisions separately. See Commonwealth v. Arrington, 
    455 Mass. 437
    , 440 n.4 (2009), quoting Commonwealth v. DeOliveira, 
    447 Mass. 56
    , 57 n.1 (2006) ("Although art. 12 has been interpreted
    to provide a criminal defendant more protection than the Sixth
    Amendment in certain circumstances, . . . 'in cases like this
    one involving the hearsay rule and its exceptions, we have
    always held that the protection provided by art. 12 is
    coextensive with the guarantees of the Sixth Amendment'"
    [citation omitted]).
    8
    We only address the meaning of unavailability in criminal
    cases where the Commonwealth is the proponent of the evidence,
    thereby implicating the defendant's right of confrontation.
    10
    and the defendant has had an adequate prior opportunity to
    cross-examine the declarant."     Commonwealth v. Hurley, 
    455 Mass. 53
    , 60 (2009).    The Sixth Amendment establishes "a rule of
    necessity, i.e., that the prosecution either produce, or
    demonstrate the unavailability of, the declarant."     Commonwealth
    v. Roberio, 
    440 Mass. 245
    , 247 (2003).
    Because there is no definition of the word "unavailability"
    in our statutes or rules, "[w]e therefore review those cases in
    which this particular exception to the hearsay rule has been
    applied."     Commonwealth v. DiPietro, 
    373 Mass. 369
    , 380 (1977).
    Although we declared in Commonwealth v. McKenna, 
    158 Mass. 207
    ,
    210 (1893), that a witness cannot be unavailable because of
    illness, we have since held that "a classic case of
    unavailability" was shown where a witness was "hospitalized
    suddenly for kidney stone surgery on the second day of . . .
    trial" and the witness's doctor stated by letter that the
    witness would not be released from the hospital until the day
    the evidence was expected to (and did) close and would not be
    available to testify until seven days later.     
    Roberio, 440 Mass. at 249-250
    .    See Mass. G. Evid. § 804(a)(4) (2014) (witness may
    be unavailable "because of . . . then-existing physical or
    mental illness or infirmity").     However, we have yet to provide
    trial judges with a framework to analyze whether a witness is
    unavailable because of illness or infirmity.     We do so now.
    11
    Where the Commonwealth claims that its witness is
    unavailable because of illness or infirmity and that it wishes
    to offer in evidence the prior recorded testimony of that
    witness, the Commonwealth bears the burden of showing that there
    is an unacceptable risk that the witness's health would be
    significantly jeopardized if the witness were required to
    testify in court on the scheduled date.   To meet this burden,
    the Commonwealth must provide the judge with reliable, up-to-
    date information sufficient to permit the judge to make an
    independent finding.   See Commonwealth v. Bohannon, 
    385 Mass. 733
    , 744-745 (1992) (second motion judge could not rely on first
    motion judge's unavailability determination made eight months
    before trial).   See also Burns v. Clusen, 
    798 F.2d 931
    , 935,
    942-943 (7th Cir. 1986) (prosecutor should have provided more
    current information where latest unavailability hearing was held
    three months before trial).   If reliable, an unsworn letter from
    a physician may be adequate, but only if it provides sufficient
    detail about the witness's current medical condition to allow
    the judge to evaluate the risk that would be posed if the
    witness were to testify in court -- a conclusory assertion is
    not enough.   See United States v. Gabrion, 
    648 F.3d 307
    , 340
    (6th Cir. 2011) (doctor's note was sufficient, because it "was
    specific as to the nature of each [witness's] illness and very
    clear in [the doctor's] opinion that the [witnesses'] health
    12
    would be jeopardized if they were forced to testify at the
    trial"); United States v. McGuire, 
    307 F.3d 1192
    , 1205 (9th Cir.
    2002) (doctor's note was sufficient where there was "no reason
    to doubt the reliability of the evidence concerning [the
    witness's] infirmity").
    A judge, in his or her discretion, may require more
    information than is contained in a doctor's letter regarding the
    witness's medical condition, and may direct the means to obtain
    that additional information, such as a supplemental letter or
    affidavit, a call to the physician over speaker telephone in the
    presence of the attorneys, a deposition of the physician, or a
    court hearing.   See United States v. Donaldson, 
    978 F.2d 381
    ,
    393 (7th Cir. 1992) (trial judge "held a hearing the day [the
    witness] was to testify to determine her availability"); Parrott
    v. Wilson, 
    707 F.2d 1262
    , 1268 (11th Cir. 1983) (parties deposed
    witness's psychiatrist).   In determining whether the risk that
    the witness's health would be jeopardized is unacceptable, a
    judge should consider the probability that the witness's
    appearance will cause an adverse health consequence, the
    severity of the adverse health consequence, such as whether it
    would be life-threatening, the importance of the testimony in
    the context of the case, and the extent to which the live trial
    13
    testimony would likely differ from the prior recorded testimony.9
    See United States v. Faison, 
    679 F.2d 292
    , 297 (3d Cir. 1982)
    (trial judge must consider witness's importance to case, nature
    and extent of cross-examination in earlier testimony, nature of
    illness, probable duration of illness, and any special
    circumstances counselling against delay).   See also Ecker v.
    Scott, 
    69 F.3d 69
    , 72 (5th Cir. 1995) (judges should consider
    "Faison factors" to determine unavailability).
    Where a judge finds that that there is an unacceptable risk
    that the witness's health would be jeopardized if the witness
    were required to testify in court on the scheduled date, the
    judge should then consider whether the risk would be acceptable
    if the trial were continued to a future date.    See Faison, supra
    at 296 (trial judge should consider possibility of adjourning
    trial for reasonable period to afford witness enough time to
    recover from illness).   Where a continuance would change the
    risk calculus, the judge should determine whether, considering
    all the circumstances, a continuance would serve the interests
    of justice, taking into account the burden of such a continuance
    on the court, the parties, the other witnesses, and the victims.
    See 
    id. at 297
    n.4.   Thus, a witness is unavailable if there is
    9
    As to this last factor, the prior recorded testimony will
    generally be similar to live trial testimony where it was
    recorded in an earlier trial in the same case, and less similar
    where it was recorded at a pretrial hearing, such as a detention
    hearing, as it was in this case.
    14
    an unacceptable risk that the witness's health would be
    jeopardized by testifying in court on the scheduled date and
    either (1) a continuance would not reduce the risk to an
    acceptable level, or (2) a continuance would make the risk
    acceptable but would not serve the interests of justice.
    In addition, before determining whether to admit prior
    recorded testimony of an unavailable witness, the judge should
    consider whether there would be an unacceptable risk that the
    witness's health would be jeopardized if the witness's testimony
    were obtained through a deposition at a suitable out-of-court
    location, such as an attorney's office, the witness's home, or a
    health facility.   See Mass. R. Crim. P. 35 (g), 
    378 Mass. 906
    (1979) (deposition admissible as substantive evidence where
    deponent is unable to testify at trial "because of . . .
    physical or mental illness or infirmity").   See also United
    States v. Keithan, 
    751 F.2d 9
    , 12-13 (1st Cir. 1984) (finding no
    abuse of discretion in admission of videotaped depositions at
    trial where one witness was "eighty-seven years old at the time
    of trial and suffered from a back condition which prevented him
    from walking" and second witness was "eighty-three years old and
    suffered from a heart condition which confined her to her
    home").   If the witness is unavailable, a deposition may be
    admissible in evidence and, especially if videotaped, may be the
    best alternative to the witness being at trial.   See United
    15
    States v. McGowan, 
    590 F.3d 446
    , 456 (7th Cir. 2009)
    ("videotapes allowed the jury to fully experience [the
    witness's] testimony, to view her demeanor, to hear her voice
    and to determine her credibility").10
    Additionally, the Commonwealth must make "a good faith
    effort to . . . produce the witness at trial."   Commonwealth v.
    Sena, 
    441 Mass. 822
    , 832 (2004).   See Commonwealth v. Ross, 
    426 Mass. 555
    , 557-558 (1998) ("The Commonwealth must exercise
    substantial diligence in order to meet its burden of showing a
    witness's unavailability").   The "good faith effort" requirement
    is most commonly at issue where unavailability stems from an
    inability to locate and procure the witness from outside the
    jurisdiction.11   But the requirement applies to all cases of
    10
    Where the witness had previously testified at a trial in
    the same case, we leave to the discretion of the trial judge
    whether, in view of the precarious health of the witness or the
    witness's present mental condition, the deposition would be
    preferable to the prior recorded testimony. Moreover, a judge
    also retains discretion to determine the form of the deposition.
    Although a videotaped deposition is generally preferable,
    because personal observation of a witness "aids immeasurably" a
    jury's evaluation of a witness's credibility, see Commonwealth
    v. Bergstrom, 
    402 Mass. 534
    , 548 (1988), it is not a perfect
    substitute for live testimony. See 
    id. at 550
    ("we cannot
    conclude that reducing the life-size picture of trial testimony
    to the image on a television screen affords to a jury the
    equivalent of personal observation").
    11
    See, e.g., Commonwealth v. Sena, 
    441 Mass. 822
    , 832-833
    (2004) (good faith demonstrated by enlisting authorities in
    Puerto Rico to search for witness one week prior to trial);
    Commonwealth v. Florek, 
    48 Mass. App. Ct. 414
    , 415-416 (2000)
    (failure to show good faith where Commonwealth knew witness's
    16
    unavailability where there is some possibility that the witness
    may be produced.    See Ohio v. Roberts, 
    448 U.S. 56
    , 74 (1980)
    (good faith requirement may apply where there is remote
    possibility that affirmative measures might produce witness).
    Where a witness is unavailable due to illness or infirmity, the
    "good faith effort" required of the Commonwealth is to promptly
    inform the court and the defendant of the unavailability of the
    witness once the Commonwealth learns of it, so that they have an
    adequate opportunity to learn more about the witness's medical
    condition and to explore the alternative of a continuance or a
    deposition.   Where the unavailability of the witness is not made
    known until the first day of trial, the defendant has little
    opportunity to investigate the witness's medical condition to
    challenge the prosecutor's claim of unavailability.   At that
    juncture, ordering a continuance or scheduling a deposition
    might be impracticable, effectively denying the defendant the
    possibility of these alternatives.
    Here, Williams received a summons on October 18, 2011, and
    returned it with a notation that she would not be able to
    testify at trial because she was under a doctor's care.
    Williams also provided the Commonwealth the doctor's letter
    dated October 24.   Yet, the Commonwealth did not file its motion
    Kentucky address but did little more than send summons to
    produce witness).

    in limine, or otherwise alert the court or the defendant of the
    witness's unavailability until November 15, the first day of
    trial.12   By not promptly informing either the defendant or the
    judge of the witness's unavailability after receipt of the
    doctor's letter, the Commonwealth limited their opportunity to
    obtain further information about the witness's medical
    condition; all that reasonably was available was the option
    invited by the doctor to telephone him for additional
    information.   This option was not pursued, and the judge rested
    his ruling solely on the doctor's letter.
    Because the letter did not provide a sufficient factual
    basis to support the judge's finding of unavailability, we
    conclude that the judge abused his discretion in making such a
    finding on the letter alone.   The doctor's medical opinion "that
    the stress of testifying in court might be detrimental to her
    health" offered no guidance as to the likelihood that testifying
    would have an adverse health consequence or as to the severity
    of the health consequence.   The letter listed the witness's
    various medical conditions but provided no guidance as to their
    stage, severity, duration, or symptoms, or as to the limitations
    they impose on everyday activity.   Nor did the letter provide
    12
    The record does not reflect when the prosecutor received
    the doctor's letter or the returned summons, but the
    Commonwealth at oral argument did not challenge the contention
    that the prosecutor learned of the witness's unavailability well
    before the judge or the defendant was advised of it.
    18
    any guidance whether the health risks would be obviated or
    significantly lessened if she were to testify through a
    deposition.   Especially where Williams offered important
    identification testimony and where her prior recorded testimony
    was taken at a pretrial detention hearing rather than an earlier
    trial, more detailed information than was provided in this
    letter is required to support a finding of unavailability.
    Although we rest our conclusion on the insufficiency of the
    doctor's letter, our conclusion is strengthened by the
    Commonwealth's failure to make the "good faith effort" of
    providing timely notice to the court and the defendant of its
    claim of unavailability.
    Having found that the defendant was denied his
    constitutional right of confrontation by the insufficiency of
    the evidence that Williams was unavailable to testify, we
    consider whether the error was harmless beyond a reasonable
    doubt.    See Commonwealth v. Burgess, 
    450 Mass. 422
    , 431-432
    (2008).   We conclude it was not.   In determining whether an
    error is harmless beyond a reasonable doubt, the "essential
    question" is whether the error had, or might have had, an effect
    on the jury and whether the error contributed to or might have
    contributed to the jury's verdicts.    Commonwealth v. Vasquez,
    
    456 Mass. 350
    , 360 (2010), quoting Commonwealth v. Perrot, 
    407 Mass. 539
    , 549 (1990).
    19
    Here, Williams's prior recorded testimony contained
    important statements of identification.   Stephen identified the
    defendant, but only as the person getting out of the truck with
    Matthew after he followed the truck out of the neighborhood.
    Williams was the only witness who recognized the defendant at
    the scene of the crime, and later identified him at an out-of-
    court identification procedure.   Neither Sivertsen nor Tobia --
    the two eyewitnesses to the crime -- could identify the
    defendant at the pretrial identification procedure.   Williams's
    identification carried evidentiary weight because she knew the
    defendant well and, at the scene of the crime, he called her by
    the name he always called her, "Grandma."   Had her prior
    recorded testimony been excluded, the jury would also not have
    heard Detective Sauvé's testimony regarding Williams's
    identification of the defendant at the identification procedure,
    because a witness's pretrial identification is admissible for
    substantive purposes only where "the identifying witness
    testifies at trial and is subject to cross-examination."
    Commonwealth v. Barbosa, 
    463 Mass. 116
    , 130 (2012).   See Mass.
    G. Evid. § 801(d)(1)(C) (2014).   Thus, we conclude that the
    erroneous admission of her testimony was not harmless beyond a
    reasonable doubt.   Therefore, we must vacate the defendant's
    convictions and remand for a new trial.
    20
    b.   Reasonable opportunity and similar motivation.     The
    defendant also claims that, even if Williams were unavailable,
    her prior recorded testimony should not have been admitted
    because the defendant did not have a reasonable opportunity or
    similar motivation to cross-examine the witness at the pretrial
    detention hearing.    See Commonwealth v. Arrington, 
    455 Mass. 437
    , 442 (2009), quoting Commonwealth v. Trigones, 
    397 Mass. 633
    , 638 (1986) (prior testimony must have been given "in a
    proceeding addressed to substantially the same issues" as
    current proceeding, with "reasonable opportunity and similar
    motivation" for cross-examination).    Because Williams may be
    found unavailable on retrial, we address this claim of error.
    "A defendant has an adequate prior opportunity to cross-
    examine an unavailable witness when (1) the declarant was under
    oath at the prior proceeding . . . ; (2) the defendant was
    represented by counsel at the prior proceeding . . . ; (3) the
    prior proceeding was conducted before a judicial tribunal,
    equipped to provide a judicial record of the hearings . . . ;
    and (4) the prior proceeding was addressed to substantially the
    same issues as in the current proceeding, and the defendant had
    [a] reasonable opportunity and similar motivation on the prior
    occasion for cross-examination of the declarant" (quotations and
    citations omitted).   
    Hurley, 455 Mass. at 60
    .   The defendant
    contends that he did not have "reasonable opportunity and
    21
    similar motivation" to cross-examine Williams at the pretrial
    detention hearing for two reasons:   first, his attorney could
    not explore any potential inconsistencies between the
    testimonies of Williams and Stephen, where the police did not
    know that Stephen was a witness at the time of the hearing; and
    second, his attorney's primary goal on cross-examination at that
    hearing was to show that the defendant would not "endanger the
    safety of any other person or the community," G. L. c. 276,
    § 58A, rather than to challenge the witness's identification or
    credibility.13
    The "reasonable opportunity" requirement was satisfied
    here, because the defendant had a reasonable opportunity to
    cross-examine the witness regarding her testimony on direct
    examination; defense counsel does not need to have had the same
    opportunity to question the witness about the testimony of other
    witnesses.   See Hurley, supra at 62-63, quoting 
    Roberio, 440 Mass. at 251
    ("what is essential is that the 'trier of fact
    [have] a satisfactory basis for evaluating the truth of the
    prior statement'").   Nor does a "reasonable opportunity" mean
    13
    To determine whether a defendant is so dangerous "that no
    conditions of release will reasonably assure the safety of any
    other person or the community," a judge may consider, among
    other issues, "the nature and seriousness of the danger posed by
    the defendant if released, and the defendant's family ties,
    employment record, history of mental illness, record of
    convictions, and reputation." Commonwealth v. Hurley, 
    455 Mass. 53
    , 61 (2009), quoting G. L. c. 276, § 58A (3), (5).
    22
    that defense counsel must have obtained the same discovery at
    the time of the prior hearing as counsel has at the time of
    trial.   See Hurley, supra at 62, quoting Delaware v. Fensterer,
    
    474 U.S. 15
    , 20 (1985) ("A defendant is not entitled under the
    confrontation clause to a cross-examination that is 'effective
    in whatever way, and to whatever extent, the defense might
    wish'").
    Although "there may be circumstances in which a defense
    counsel's motive to cross-examine a declarant at a pretrial
    detention hearing may differ from her motive to cross-examine at
    trial, such as where the defense counsel did not challenge the
    declarant's accuracy or credibility at cross-examination in the
    prior hearing and focused solely on challenging the defendant's
    dangerousness," Hurley, supra at 63 n.9, those are not the
    circumstances of this case.   The defendant's cross-examination
    of Williams focused primarily on challenging the reliability of
    her identification of the defendant and distinguishing what
    Williams actually saw from what she learned from other
    witnesses.   Defense counsel elicited Williams's admission that
    she did not see anybody fire the gun, that her information about
    who fired the gun or that a gun was fired at all came from other
    witnesses, and that she could not be sure whether the bearded
    man shown in the photographic array was the same person she
    identified in the single photograph.   Although the cross-
    23
    examination also established that the defendant had never
    threatened Williams, and that she had never heard that he had
    engaged in violent behavior, the primary focus of the cross-
    examination was not to demonstrate that the defendant was not
    dangerous.   Nor could it reasonably have been the primary focus,
    where Williams only knew the defendant as her grandson's
    childhood friend and had not seen him for one and one-half years
    prior to the incident.   Therefore, we conclude that if Williams
    is determined to be unavailable, redacted portions of her
    pretrial testimony would be admissible on retrial.14
    2.   Admission of photographs of similar firearm.   At trial,
    Tobia testified that the firearm in the defendant's possession
    was a silver-colored Derringer, stating that he recognized it as
    such because his father is an avid hunter who owns a few
    Derringers and that he has "handled" Derringers.   The
    14
    Because the issue may arise on retrial, we emphasize that
    Williams's pretrial testimony should not be admitted in its
    entirety. Some of her prior testimony contained hearsay that is
    admissible at a pretrial detention hearing under G. L. c. 276,
    § 58A, see Abbott A. v. Commonwealth, 
    458 Mass. 24
    , 34 (2010),
    but would not be admissible at trial unless it fell within a
    hearsay exception. See Commonwealth v. Wright, 
    469 Mass. 447
    ,
    464-465 (2014) (some of witness's prior recorded testimony,
    conveying what her husband had said, "constitute[d] classic
    'totem pole' or 'layered' hearsay" and would not be admissible).
    Moreover, some of her testimony at the pretrial detention
    hearing vouched for the truthfulness of Sivertsen and Tobia, and
    should not be admitted. See Commonwealth v. Quinn, 
    469 Mass. 641
    , 646 (2014) ("No witness, neither a lay witness nor an
    expert, may offer an opinion regarding the credibility of
    another witness").
    24
    Commonwealth presented two photographs to Tobia that he said
    depicted a Derringer, although not the Derringer Tobia actually
    saw on May 11.   Even though both the prosecutor and defense
    counsel pointed out that the photographs did not show the actual
    gun used, the defendant objected to the admission of the
    photographs in evidence and argues on appeal that the judge
    abused his discretion in admitting them.   In the event the issue
    is raised again on retrial, we conclude that it was not an abuse
    of discretion for the judge to admit the exemplar photographs.
    "Where for whatever reasons original items of physical
    evidence cannot be produced, substitutes similar to the
    originals have often been received as exhibits, in criminal as
    well as civil trials, to illustrate and corroborate testimony in
    which the originals figured:   the admission of such [exemplars]
    is well understood to rest in the discretion of the court."
    Commonwealth v. Luna, 
    46 Mass. App. Ct. 90
    , 93 (1998).     Where it
    is made clear at trial that photographs simply depict a similar-
    looking firearm and do not depict the actual firearm used in the
    incident, it is not an abuse of discretion to admit the exemplar
    photographs.   See Commonwealth v. Ellis, 
    373 Mass. 1
    , 7 (1977)
    (no abuse of discretion where "prosecution made it clear by
    questions that the model was not the murder weapon but was
    merely illustrative"); Commonwealth v. Souza, 
    34 Mass. App. Ct. 436
    , 444-445 (1993) (spiked wristband "similar but perhaps not
    25
    identical" to one used in crime was admissible where questioning
    made clear that witness could not say that exemplar wristband
    was actual wristband used in attack).   Although the judge did
    not give a limiting instruction to remind the jury that the
    photographs were only exemplars, see Commonwealth v. Stewart,
    
    398 Mass. 535
    , 542 n.6 (1986), such an instruction is not
    mandatory and was not necessary where the status of the
    photographs as exemplars was made clear from the testimony.15
    See Luna, supra at 94 (absence of limiting instruction was not
    error where fact "[t]hat the exhibit was only a stand-in was
    stated repeatedly . . . could not have been lost on the jury").
    3.   Sufficiency of evidence for conviction of unlawful
    carrying of a firearm.   At the close of the Commonwealth's
    evidence and again at the close of all the evidence, the judge
    denied the defendant's motion for a required finding of not
    guilty as to the charge of unlawful carrying of a firearm, in
    violation of G. L. c. 269, § 10 (a).    On appeal, the defendant
    contends that the evidence was insufficient as a matter of law,
    because to be a "firearm," as defined under G. L. c. 140, § 121,
    the weapon must be capable of discharging a shot or bullet.      See
    Commonwealth v. Sampson, 
    383 Mass. 750
    , 753 (1981) (firearm must
    be "[1] a weapon, [2] capable of discharging a shot or bullet,
    15
    The judge declared that he intended to give a limiting
    instruction on the exemplars but did not do so. There was no
    objection to the absence of a limiting instruction.
    26
    and [3] under a certain length").16   We address this issue even
    though we have vacated the convictions because, if the defendant
    is correct, he would be entitled to a judgment of acquittal and
    not merely a new trial.
    We conclude that, viewed in the light most favorable to the
    Commonwealth, the evidence was sufficient to permit a reasonable
    jury to conclude beyond a reasonable doubt that the gun the
    defendant displayed was capable of discharging a bullet, even
    where there was no gun found, no casings or bullets recovered,
    no ballistics evidence, and no expert testimony.   As earlier
    noted, Tobia testified that he saw the defendant point a gun at
    him, which he knew to be a Derringer from his experience with
    firearms.   He saw the defendant struggle with the gun after it
    misfired, break it open to extract two shells, load it again,
    and fire it at him.   When the gun fired, Tobia "saw the flash
    come out of the barrel of the gun," and heard a "big, bang
    noise," which sounded "exactly the same" as the gunshots he had
    heard when he went shooting with his father.17   From the
    16
    The Commonwealth need not show that the gun was actually
    capable of discharging a bullet at the time of the incident; it
    need only show that the gun was capable of doing so with a
    "relatively slight repair, replacement, or adjustment."
    Commonwealth v. Bartholomew, 
    326 Mass. 218
    , 220 (1950). See
    Commonwealth v. Jefferson, 
    461 Mass. 821
    , 828 (2012).
    17
    Sivertsen also testified to seeing a small, silver gun
    and hearing a "loud bang like a gun noise." Stephen Borges
    testified that from the apartment cellar he heard "a gunfire go
    27
    witnesses' testimony, a reasonable jury could find beyond a
    reasonable doubt that the defendant loaded and then fired a
    weapon that looked like a gun, sounded like a gun, and flashed
    like a gun.   With this evidence, a reasonable jury did not need
    expert testimony to find beyond a reasonable doubt that the gun
    was capable of discharging a bullet and, consequently, was a
    "firearm" that was unlawfully carried by the defendant.   See
    Commonwealth v. Tuitt, 
    393 Mass. 801
    , 809-810 (1985) (expert
    testimony unnecessary to prove gun was capable of discharge
    where defendant threatened victim with gun and said, "Don't get
    killed over anybody else's money"); Commonwealth v. Stallions, 
    9 Mass. App. Ct. 23
    , 25-26 (1980) (jury could determine whether
    revolver was capable of discharging bullet without any evidence
    that revolver had been tested and found operable).
    Conclusion.   We conclude that the judge erred by allowing
    the Commonwealth to introduce prior recorded testimony without
    sufficient proof of the witness's unavailability.    Because the
    error was not harmless beyond a reasonable doubt, we vacate the
    judgments of conviction and remand the case for a new trial
    consistent with this opinion.
    So ordered.
    off," and that he could discern that the sound was gunfire
    because he was "brought up around guns" and could distinguish
    between a gunshot and fireworks. Moreover, the across-the-
    street neighbor, Paul Sarmento, testified to hearing a sound
    like a truck backfiring -- "a pow sound."
