    LENK, J.     The defendant was convicted of murder in the
    first degree for a shooting that took place in an alleged
    territorial conflict over the control of a "crack house," an
    apartment used to sell "crack" cocaine.      The bulk of the
    2
    evidence at trial against the defendant and his codefendant at
    trial, Levino Williams, who was acquitted, derived from the
    testimony of a single witness, James Jackson.   Jackson was a
    crack addict and alcoholic who lived in the apartment, allowed
    others to sell drugs there in exchange for free drugs, and
    claimed to have witnessed the defendant shoot the victim,
    Michael Greene.   Approximately one and one-half years after the
    defendant’s conviction, another individual, Debra Bell,1 came
    forward.    Explaining that she had been diagnosed with metastatic
    cancer and did not want her failure to disclose what she knew
    about the shooting on her conscience, Debra claimed in an
    affidavit that she was with Jackson using drugs and having sex
    in the bathroom of the apartment at the time the shooting took
    place, and that as a result Jackson could not have seen the
    shooting.
    Based on Debra's affidavit, the defendant moved for a new
    trial on the ground of newly discovered evidence.   Defense
    counsel also moved to take a videotaped deposition to preserve
    Debra's testimony.   Debra died, however, one week after the
    motion was filed, and before the judge acted on it.   The motion
    judge, who was also the trial judge, concluded that Debra's
    affidavit was inadmissible hearsay, and denied the motion for a
    1

    Betty Jo Bell, who is also relevant to this case, we refer to
    both by their first names.

    new trial.   The defendant later submitted a second motion for a
    new trial, which the judge also denied.   In that motion, the
    defendant argued that trial counsel acted ineffectively in
    failing to call an expert witness regarding the effects of drug
    and alcohol use or sleep deprivation on Jackson's testimony, and
    that he was deprived of his right to a public trial due to the
    unobjected-to exclusion of his mother and friend from the court
    room during the jury empanelment process.
    The case comes to this court on a consolidated appeal from
    the convictions of murder in the first degree and unlawful
    possession of a firearm, and from the denial of the defendant's
    motions for a new trial.   We reject the claims of error at trial
    that the defendant asserts, both on direct appeal and in his
    second motion for a new trial,2 and decline to grant the
    defendant relief under G. L. c. 278, § 33E.   However, with
    regard to the defendant's first motion for a new trial, based on
    newly discovered evidence, we conclude that, under the unusual
    circumstances of this case, there is a substantial issue whether
    Debra's affidavit falls within a narrow, constitutionally based
    exception to the hearsay rule, which applies where otherwise
    inadmissible hearsay is critical to the defense and bears
    2
    The defendant does not assert before this court the
    arguments that he made in his second motion for a new trial, but
    we review them pursuant to our obligations under G. L. c. 278,
    § 33E.

    persuasive guarantees of trustworthiness.    We therefore remand
    for an evidentiary hearing on that issue.3
    1.   Background.   a.   Evidence at trial.   The Commonwealth
    offered evidence at trial that supported the following theory of
    the crime.   Since 1993, Jackson had leased an apartment in
    Boston.   Several months before the shooting, Jackson became
    acquainted with Greene, who was a crack dealer.     In exchange for
    money and free drugs, Jackson authorized Greene to sell crack
    cocaine out of the apartment, and permitted other individuals to
    use crack cocaine in the apartment.
    In the weeks leading up to the shooting, Jackson and Greene
    had entered into a dispute, due to Greene's increasingly violent
    behavior and his efforts to exert control over the apartment.
    At the same time, Jackson entered into an arrangement with the
    defendant, and with his codefendant, Williams, similar to his
    arrangement with Greene:     Jackson permitted them to sell drugs
    from the apartment, and in exchange received from them free
    drugs and financial support.    One week before the shooting,
    Jackson informed Greene that he no longer wanted him selling
    drugs in the apartment.
    On the day of the shooting, September 20, 2001, the
    defendant and Williams were in the apartment, rolling "oolies" -
    3
    We recognize that the trial judge is now retired and that
    such a hearing must be conducted by a different judge.
    5
    - cigarettes laced with cocaine and "reefer" -- and drinking.
    Greene appeared, and Jackson again informed him that he was no
    longer permitting him to sell drugs in the apartment.   Greene
    became enraged.   He made a call from a cellular telephone, and
    threatened to "kill 'em all" and burn down the apartment.     While
    Greene was on the telephone, Jackson went into the bathroom.     As
    Jackson was preparing to leave the bathroom, he heard a gunshot.
    When he emerged from the bathroom and entered the living room,
    he observed the defendant fire five additional shots at Greene.
    The defendant shot the victim using a gun that Jackson had
    observed in the defendant's waistband several days previously.
    At trial, Jackson was the sole percipient witness to the
    shooting; he was also the sole source of evidence regarding the
    conflict among the defendant, Williams, and Greene that
    allegedly motivated the shooting.   The problems with Jackson's
    credibility were legion.   He indicated that he had begun
    drinking alcohol at age seven, began using cocaine at age
    twenty-eight, and had been using crack cocaine for nearly a
    decade prior to the shooting.   He acknowledged that he had been
    smoking crack and drinking alcohol on the day of the shooting,
    and had been awake nearly continuously in the days leading up to
    the shooting.   He explained his belief that that his drug and
    alcohol use would not have affected his ability to perceive the
    shooting by noting that, because he had been using drugs and
    6
    alcohol "24-7 . . . over a period of years," he was "immune" to
    the effects of them.
    Jackson's testimony at trial contradicted his initial
    statement to police during an emergency 911 call, in which he
    indicated that an unknown assailant had pushed through the
    apartment door and shot Greene.   His testimony at trial also
    partly contradicted prior testimony before the grand jury.
    Jackson told the grand jury that he saw Williams standing close
    behind the defendant as the defendant fired at Greene.   At
    trial, however, Jackson asserted that this testimony was untrue,
    and that he had not seen Williams when the defendant shot
    Greene.
    Jackson's testimony was replete with other inconsistencies
    and seeming obfuscations.   For instance, Jackson insisted that
    his earlier statement to police officers that he "had a pint of
    Hennessy" on the day of the shooting did not mean that he drank
    a pint of Hennessy cognac on that day, but merely that he
    possessed a pint of Hennessy, of which he drank some.
    Confronted with the apparent conflict between his grand jury
    testimony that he "never slept" on the day before the shooting
    and his trial testimony that he "took a nap" the night before
    the shooting, Jackson insisted that he did not "call taking a
    nap sleeping," but merely "resting [his] eyes."   Similarly,
    while Jackson provided the times for various events to police
    7
    officers in an initial interview on the day of the shooting, he
    asserted at trial that "all those times were just a guess time,"
    explaining that he "didn't keep up with no time" because he "had
    no place to go" and "didn't have to worry about the time."
    Jackson acknowledged near the end of his testimony that he "made
    a whole lot of mistakes in [his] testimony."
    Despite the severe challenges to Jackson's credibility, the
    Commonwealth offered little additional evidence to corroborate
    his account.    The Commonwealth never located the firearm used in
    the shooting.   The physical evidence offered at trial linking
    the defendant to the apartment was limited to a beer bottle,
    which a prosecution expert testified contained a latent
    fingerprint that matched the defendant's right middle finger
    joint, and a cellular telephone, which was traced to a person
    known to both the defendant and Williams.   Several items of
    physical evidence, including the telephone and crack cocaine
    seized from the apartment, were lost while in police custody
    before the trial.
    b.   Postconviction proceedings.    A Superior Court jury
    convicted the defendant of murder in the first degree, on
    theories of both deliberate premeditation and extreme atrocity
    or cruelty, in April, 2005.   The defendant also was convicted of
    unlawful possession of a firearm.   Williams, who was tried with
    the defendant as a joint venturer, was acquitted of the same
    8
    offenses.
    On December 12, 2006, while the defendant's appeal of his
    convictions was still pending, the defendant filed his first
    motion for a new trial based on newly discovered evidence, in
    the form of Debra's affidavit.   Debra had given a statement to
    police shortly after the shooting, but she had otherwise avoided
    speaking to attorneys and others investigating the crime.     In
    her affidavit, she claimed that her statement to police was "not
    completely truthful" because she "was afraid of the officers,
    . . . did not want to get involved in the case," and had been
    told that "the officers . . . would take care of arrest warrants
    that were pending against [her] in different courts."   She
    apparently made herself unavailable to testify at a motion to
    suppress hearing that occurred shortly before trial, and at
    trial itself.
    Whereas Jackson testified at trial that he was in the
    bathroom by himself when the first shot was fired, and emerged
    from the bathroom to witness the defendant fire several
    additional shots at the victim, Debra asserted in her affidavit
    that she was in the bathroom with Jackson at the time of the
    shooting, and that Jackson remained in the bathroom for the
    entirety of the shooting.   Debra said that, after hearing noises
    from outside the bathroom, she waited a few minutes before
    opening the door and "briefly peek[ing] out," at which point she
    9
    saw "a person's legs on the floor."    She "screamed to . . .
    Jackson to look out the door," to which he "replied the 'Hell
    with it' or words to that effect and slammed the door closed,"
    stating that "he did not care about what was going on."     Debra
    concluded that "there was absolutely no way that either he or
    [she] could have seen who shot . . . Greene or who was in the
    apartment at that time."
    After Debra's death in December, 2006, defense counsel
    submitted additional support for his first motion for a new
    trial, in the form of affidavits from two additional witnesses.
    One affidavit came from Betty Jo, Debra's sister.   Like Debra,
    Betty Jo also gave a statement to police shortly after the
    shooting, although she too claimed that she was "not truthful"
    because she "was afraid of the officers" and they had offered to
    "'clear' about three warrants that were pending for [her]
    arrest" if she cooperated with them.   Betty Jo also testified at
    a hearing on the defendants' pretrial motions to suppress, her
    name appeared on the Commonwealth's witness list for trial, and
    she was available to testify during the trial.   Shortly before
    the trial, however, she indicated that she refused to speak to
    defense counsel, and neither party called her at trial.
    In her affidavit, Betty Jo indicated that "[e]very now and
    then after the shooting on September 20, 2001, . . . Debra . . .
    would tell [her] about what had occurred in the apartment . . .
    10
    and she would say that she and . . . Jackson were in the
    bathroom getting high on crack cocaine and engaging in sexual
    activity when the shooting occurred."   Betty Jo also claimed
    that Jackson had admitted to her, nearly five years after the
    shooting, that he and Debra were in the bathroom "doing their
    thing" and that he "did not know what was going on" at the time
    of the shooting.   Betty Jo stated that she had accompanied Debra
    to her interview with police after the shooting, and both had
    been independently interviewed by officers investigating the
    crime.   She asserted that, during the interview, police officers
    sought to prompt her to identify certain photographs even though
    she did not recognize them.
    Defense counsel also submitted two affidavits from an
    individual named Joseph Anderson, which further support Debra's
    account of the events leading up to the shooting.    Anderson
    indicated that he went to Jackson's apartment on September 20,
    2001, to purchase crack cocaine for a friend.   He stated that,
    after he made the purchase from Jackson, he "saw . . . Jackson
    going into the bathroom with a black woman, who was known to
    [him] as Debra."   Anderson observed "two black males and one
    black female sitting . . . in the parlor" when he purchased the
    crack cocaine; upon leaving, he also "saw a black male, who was
    standing in the hallway in the apartment arguing with a light
    skinned male, who appeared to be Puerto Rican."     Finally,
    11
    Anderson indicated that, "[a]bout three or four days after the
    shooting," he encountered Jackson at a liquor store.     The two
    conversed, and Jackson allegedly said that he did not "know
    anything about" the shooting and did not "give a fuck about it."
    In November, 2007, the motion judge, who was also the trial
    judge, denied the defendant's first motion for a new trial in a
    brief opinion.   The judge explained that she initially
    considered holding an evidentiary hearing, but concluded based
    on her review of the affidavits that an evidentiary hearing was
    not necessary.   The judge explained that, were Debra alive, "her
    testimony . . . would tend to impeach the testimony of Jackson
    [and] would not be sufficient to warrant a new trial."     The
    judge further observed that Debra's alleged statements would not
    be admissible as a "dying declaration" because they did not
    concern the cause or the circumstances of her own death.
    Although the defendant argued that his constitutional rights
    under the Sixth and Fourteenth Amendments to the United States
    Constitution and art. 12 of the Massachusetts Declaration of
    Rights required the admissibility of the affidavit regardless
    whether it constituted a dying declaration under State
    evidentiary law, the judge's decision did not address that
    argument.
    The defendant filed a second motion for a new trial in
    April, 2012.   There he asserted an ineffective assistance of
    12
    counsel claim, based on trial counsel's failure to offer expert
    testimony regarding the impact of sleep deprivation on
    perception and memory to impeach Jackson's testimony, and a
    claim for a violation of the right to a public trial, based on
    the alleged exclusion of a family member and a friend from the
    jury empanelment process.    After an evidentiary hearing, the
    judge denied the defendant's second motion for a new trial.
    2.   Discussion.    The defendant raises three specific issues
    on appeal; in addition, he urges the court to grant him relief
    pursuant to its general superintendence power under G. L.
    c. 278, § 33E.   The first issue relates to the conduct of the
    trial itself:    the defendant contends that the trial judge
    improperly admitted certain testimony of the Commonwealth's
    fingerprint expert.    We reject that argument, as well as the two
    arguments that the defendant asserted in his second motion for a
    new trial, and decline to grant the defendant relief under G. L.
    c. 278, § 33E.   The second issue relates to the judge's denial
    of the defendant's motion for a new trial based on newly
    discovered evidence.    We conclude that the defendant's motion
    raised a substantial issue, and therefore remand for an
    evidentiary hearing.    The third issue relates to defense
    counsel's posttrial conduct with respect to the defendant's
    motion for a new trial:    the defendant argues that defense
    counsel did not act sufficiently quickly to move for a
    13
    videotaped deposition of Debra, thus depriving the defendant of
    effective assistance of counsel.    In light of our remand for an
    evidentiary hearing on the defendant's motion for a new trial
    based on newly discovered evidence, we decline to reach that
    issue.
    a.   Issues on direct appeal.    The Commonwealth's expert
    testified that she "individualized or identified" a latent
    fingerprint found on a beer bottle at the crime scene to
    defendant's "right middle finger joint."   The defendant contends
    that the admission of this testimony was in error.    Because
    trial counsel did not object, we review to determine "whether
    there was error, and if so, whether it created a substantial
    likelihood of a miscarriage of justice."    Commonwealth v. Perez,
    
    460 Mass. 683
    , 689-690 (2011).
    We have "concluded that the underlying theory and process
    of latent fingerprint identification . . . are sufficiently
    reliable to admit expert opinion testimony regarding the
    matching of a latent impression with a full fingerprint"
    (citation and quotation omitted).    Commonwealth v. Wadlington,
    
    467 Mass. 192
    , 204 (2014).   We have "warned," however, "that
    testimony to the effect that a print matches, or is
    'individualized' to, a known print should be presented as an
    opinion, not a fact, and opinions expressing absolute certainty
    about, or the infallibility of, an 'individualization' of a
    14
    print should be avoided"    (citation, quotation, and alterations
    omitted).   
    Id. Here, on
    direct examination, the expert
    testified that the print was "individualized or identified" with
    the defendant's print, but did not describe that
    individualization as an absolute certainty.    On cross-
    examination the expert did indicate that she was "positive that
    [she] identified" the defendant's print.     Because this testimony
    occurred on cross-examination, however, and because there was no
    motion to strike, we identify no error in the testimony, much
    less an error sufficient to create a substantial likelihood of a
    miscarriage of justice.    See 
    id. at 205.
    b.     Relief under G. L. c. 278, § 33E.   Pursuant to our
    obligations under G. L. c. 278, § 33E, we have reviewed the
    entire record and considered the issues raised in the
    defendant's second motion for a new trial.     We agree with the
    motion judge's determination that, because the effects of
    Jackson's alcohol and drug use and sleep deprivation on his
    capacity to perceive and recall events were thoroughly developed
    through cross-examination, calling an expert on those issues
    would not have accomplished something meaningful for the
    defense.    We also conclude that the motion judge properly
    determined that the defendant had not borne his burden of
    demonstrating that the court room was closed during any portion
    of the jury selection, because the defendant offered no evidence
    15
    indicating that the court room was closed by any specific order
    or that court officers ever told anyone to leave.     We identify
    no basis to exercise our authority pursuant to G. L. c. 278,
    § 33E, either to reduce the verdict of murder in the first
    degree or to order a new trial.
    c.      Motion for a new trial on the basis of newly discovered
    evidence.    Under Mass. R. Crim. P. 30 (b), as appearing in 
    435 Mass. 1501
    (2001), a trial judge "may grant a new trial at any
    time if it appears that justice may not have been done."     Where
    the defendant moves for a new trial on the basis of newly
    discovered evidence, the defendant "must establish both that the
    evidence is newly discovered and that it casts real doubt on the
    justice of the conviction," which entails a showing that it
    "probably would have been a real factor in the jury's
    deliberations."     Commonwealth v. Grace, 
    397 Mass. 303
    , 305-306
    (1986).     The defendant "also bears the burden of demonstrating
    that any newly discovered evidence is admissible."     Commonwealth
    v. Weichell, 
    446 Mass. 785
    , 799 (2006).
    In adjudicating a motion for a new trial, the "judge may
    rule on the issue or issues presented by such motion on the
    basis of the facts alleged in the affidavits without further
    hearing if no substantial issue is raised by the motion or
    affidavits."     Mass. R. Crim. P. 30 (c), as appearing in 
    435 Mass. 1501
    (2001).     "When a substantial issue has been raised,
    16
    and supported by a substantial evidentiary showing," however,
    "the judge should hold an evidentiary hearing" (citation and
    quotation omitted).     Commonwealth v. Muniur M., 
    467 Mass. 1010
    ,
    1011 (2014).    See also Reporters' Notes to Rule 30, Mass. Ann.
    Laws Court Rules, Rules of Criminal Procedure, at 1709
    (LexisNexis 2014-2015) ("Where a substantial issue is
    raised, . . . the better practice is to conduct an evidentiary
    hearing").     We generally review a judge's decision on a motion
    for a new trial under an abuse of discretion standard.
    Commonwealth v. Muniur M., supra at 1012.     Where the defendant's
    motion for a new trial raises an issue "of constitutional
    dimension," however, "we are not bound by an abuse of discretion
    standard, but rather examine the issue independently."
    Commonwealth v. Conkey, 
    443 Mass. 60
    , 66-67, (2004), S.C., 
    452 Mass. 1022
    (2008).     Because we conclude that the defendant's
    first motion for a new trial raises a sufficiently substantial
    issue whether Debra's affidavit falls within a narrow,
    constitutionally based exception to the hearsay rule, we remand
    for an evidentiary hearing.
    The judge's decision to deny the defendant's first motion
    for a new trial without holding an evidentiary hearing appears
    to have rested in large part on the judge's determination that
    Debra's affidavit was not admissible as a dying declaration.
    That determination, as the defendant concedes, was correct.
    17
    Under the "dying declaration" exception to the hearsay rule, "a
    statement made by a declarant-victim" is admissible in a
    prosecution for homicide, provided that the statement was made
    "under the belief of imminent death," that the declarant "died
    shortly after making the statement," and that the statement
    "concern[ed] the cause or circumstances of what the declarant
    believed to be her own impending death."    Commonwealth v.
    Nesbitt, 
    452 Mass. 236
    , 251-252 (2008).    Because Debra's
    statement in her affidavit did not concern the cause or
    circumstances of her impending death, her statement is not
    admissible under the traditional hearsay exception for dying
    declarations.
    The defendant also correctly concedes that this court has
    not yet recognized, as a matter of evidentiary law, any other
    hearsay exception that would encompass Debra's affidavit.     For
    instance, the Federal rules of evidence include a "residual"
    exception, which allows the admission of hearsay evidence that
    is not admissible under any other exception where the court
    determines that (a) "the statement has equivalent guarantees of
    trustworthiness"; (b) "the statement is offered as evidence of a
    material fact"; (c) the statement "is more probative on the
    point for which it is offered than any other evidence that the
    proponent can obtain through reasonable efforts"; and (d) "the
    purposes of [the] rules [of evidence] and the interests of
    18
    justice" will best be served by the admission of the statement
    into evidence.   Fed. R. Evid. 807.   Thirty-one States have
    adopted some form of a "residual" or "catchall" exception to the
    hearsay rule, often patterned on the Federal rule.4    On several
    occasions, however, this court has declined to recognize an
    "'innominate' or residual exception to the hearsay rule"
    (citation and quotation omitted) akin to the Federal residual
    exception.   Commonwealth v. Pope, 
    397 Mass. 275

      The United States Supreme Court

    Id. at 302.
        The
    Court observed that, "[a]lthough perhaps no rule of evidence has
    been more respected or more frequently applied in jury trials
    than that applicable to the exclusion of hearsay, exceptions
    tailored to allow the introduction of evidence which in fact is
    likely to be trustworthy have long existed."       
    Id. Because the
    sworn confession at issue in the case "bore persuasive
    assurances of trustworthiness" and "also was critical to [the
    defendant's] defense," the Court concluded that "the hearsay
    rule may not be applied mechanistically to defeat the ends of
    justice."   
    Id. See Green
    v. Georgia, 
    442 U.S. 95
    , 97 (1979)
    (constitutionally impermissible for State to apply hearsay rule
    to bar third-party confession where confession was "highly
    relevant to a critical issue in the punishment phase of the
    trial" and "substantial reasons existed to assume its
    reliability").
    This court has already recognized a constitutionally based
    hearsay exception in one context.       Because the right to defend
    against criminal charges by presenting third-party culprit
    22
    evidence "is of a constitutional dimension," we have held that a
    defendant may offer otherwise inadmissible hearsay evidence to
    support the assertion that a third party is the true culprit,
    provided certain conditions are met.    Commonwealth v. Silva-
    Santiago, 
    453 Mass. 782
    , 801, 804 n.26 (2009).    The defendant
    must establish that the hearsay statement is "otherwise
    relevant, will not tend to prejudice or confuse the jury,"
    displays "substantial connecting links to the crime," has "a
    rational tendency to prove the issue the defense raises," and is
    not "too remote or speculative" (citations and quotations
    omitted).   
    Id. at 804.
      See Commonwealth v. Morgan, 
    449 Mass. 343
    , 355-357 (2007); Mass. G. Evid. § 1105 (2015).
    To be sure, Debra's affidavit does not constitute third-
    party culprit evidence.   The United States Supreme Court's
    decision in Chambers, however, was not expressly limited to
    third-party culprit evidence.   The Supreme Court and other
    courts have applied the principle articulated in Chambers to
    cases that did not involve the exclusion of third-party culprit
    evidence.   See Crane v. Kentucky, 
    476 U.S. 683
    , 690-691 (1986)
    (holding that trial court violated principle articulated in
    Chambers when it barred defendant from introducing evidence to
    challenge voluntariness of his confession); State v. Bunyan, 
    154 N.J. 261
    , 265, 269-272 (1998) (applying Chambers principle to
    affidavit from purported eyewitness asserting that defendant did
    23
    not commit crime of which he was convicted).
    We identify no persuasive reasons for confining our
    recognition of a constitutionally based hearsay exception to the
    context of third-party culprit evidence.    Third-party culprit
    evidence challenges the prosecution's case in a way that, while
    potentially powerful, is ultimately indirect:   it seeks to
    create reasonable doubt as to the defendant's guilt by
    suggesting that another person in fact committed the crime.      An
    affidavit that directly contradicts the testimony of the sole
    purported eyewitness to a crime likewise undermines the
    prosecution's case in a way that is indirect yet potentially
    powerful.   Accordingly, we believe that the principle
    articulated in Chambers applies to Debra's affidavit:    the
    affidavit will be admissible, despite its failure to fall into
    any of our traditional hearsay exceptions, provided that the
    defendant establishes both that it "[i]s critical to [the
    defendant's] defense" and that it bears "persuasive assurances
    of trustworthiness."   
    Chambers, 410 U.S. at 302
    .
    Having recognized that the principle articulated in
    Chambers applies to Debra's affidavit, we conclude that the
    defendant's first motion for a new trial raises a substantial
    issue, warranting an evidentiary hearing.    Debra's affidavit
    plainly would have been critical to the defense.    The affidavit
    directly contradicts Jackson's testimony, indicating that he
    24
    could not possibly have observed what he claimed at trial to
    have observed.   Jackson's other testimony suggested that both
    the defendant and the defendant's acquitted codefendant,
    Williams, had a motive to murder Greene.   In the absence of
    Jackson's statement that he saw the defendant shooting Greene,
    however, there is no evidence that makes it more likely than not
    -- much less evidence capable of proving beyond a reasonable
    doubt -- that the defendant, rather than Williams, was the
    perpetrator.
    Because Debra's affidavit is critical to the defense, its
    admissibility hinges on whether the defendant establishes that
    it bears persuasive assurances of trustworthiness.   Although the
    record as it stands does not permit us to answer that question,
    the evidence submitted by the defendant establishes that there
    is a substantial issue whether the affidavit has sufficient
    assurances of trustworthiness.   In reaching this determination,
    we draw on several instructive similarities between the
    circumstances at issue here and those involved in Chambers.      Cf.
    Montana v. Egelhoff, 
    518 U.S. 37
    , 52-53 (1996) (plurality
    opinion) (characterizing Chambers as "fact-intensive" and "an
    exercise in highly case-specific error correction"); State v.
    
    Bunyan, 154 N.J. at 270
    ("Because the holding of Chambers is so
    intimately related to the facts and circumstances of that
    case, . . . we must consider the facts of Chambers and compare
    25
    them to the facts of this case" [citation and quotation
    omitted]).
    In 
    Chambers, 410 U.S. at 300-301
    , the United States Supreme
    Court observed that, while the hearsay statement at issue fell
    outside of the hearsay exception for statements against
    interest, the admission of the statement was consistent with the
    underlying "rationale" for that exception.   Here, similarly,
    while Debra's affidavit fails to satisfy the technical
    requirements for the dying declaration hearsay exception, it
    appears to fall within the rationale for the exception.   A
    traditional justification for the dying declaration exception is
    that, when a person is "under a sense of impending death" and
    "every hope of this world is gone[,] . . . the mind is induced
    by the most powerful considerations to speak the truth"
    (citations and quotations omitted).   Giles v. California, 
    554 U.S. 353
    , 397 (2008).   See Chia v. Cambra, 
    360 F.3d 997
    , 1006
    (9th Cir. 2004) (although hearsay statement at issue did "not
    technically meet the definition of a dying declaration, it was
    given when [the declarant] knew that he was in real danger of
    imminent death -- a traditional indicium of reliability").
    Consistent with that justification, in her affidavit Debra
    attributed her decision to come forward to the "uncertainty of
    [her] medical condition" and her desire to clear her conscience
    of her prior failure to come forward with what she knew about
    26
    the shooting.   Indeed, according to Betty Jo, Debra's plea that
    she "make the truth known about the shooting in . . . Jackson's
    apartment" was her "sister's dying words."   These circumstances,
    particularly given that the Commonwealth has as of yet offered
    no alternative explanation for why Debra would have an incentive
    to lie in her affidavit, tend to support the trustworthiness of
    Debra's statement.
    The United States Supreme Court also observed in 
    Chambers, 410 U.S. at 300
    , that the hearsay statement at issue bore
    persuasive assurances of trustworthiness because it "was
    corroborated by some other evidence in the case."   Here
    similarly, Debra's affidavit is corroborated by Jackson's own
    initial statements to police, in which he asserted that he did
    not see the shooter.   The four affidavits of Debra, Betty Jo,
    and Anderson, moreover, bolster one another through their
    inclusion of shared details.   For instance, Jackson testified at
    trial that only he, the defendant, Williams, and the victim were
    present in the apartment at the time of the shooting.     Both
    Debra and Anderson, however, indicate that there were others
    present moments before the shooting.   Debra and Anderson appear
    to have observed one another, with Anderson remarking that he
    "saw . . . Jackson going into the bathroom with a black
    woman . . . known to [him] as Debra," and Debra observing that
    she saw "a black male known to [her] as Joe."   Both Debra and
    27
    Betty Jo also observed the presence of a woman known to them as
    "Sandra."
    Finally, in Chambers the Supreme Court remarked that the
    third party confessed on multiple occasions.    The Court
    concluded that "[t]he sheer number of independent confessions
    provided additional corroboration for each," particularly since
    each confession "was made spontaneously to a close acquaintance
    shortly after the murder had occurred."   
    Id. Here, Betty
    Jo's
    affidavit indicates that, following the shooting and until
    Debra's death, Debra on multiple occasions told her "that she
    and . . . Jackson were in the bathroom at the time of the
    shooting and that they could not see what had occurred or who
    had been involved in the shooting."
    In identifying these elements that arguably may support the
    trustworthiness of Debra's affidavit, we do not in any way
    suggest that the affidavit ultimately is admissible.    We
    conclude only that there is a substantial issue whether Debra's
    affidavit is supported by sufficiently persuasive guarantees of
    trustworthiness that it is admissible under the constitutional
    principle articulated in Chambers, and that the resolution of
    that issue will benefit from an evidentiary hearing.6
    6
    There is no indication in the record that either Betty Jo
    or Anderson is unavailable to testify and expand upon the
    matters addressed in their affidavits. Were they to testify at
    an evidentiary hearing on the defendant's motion for a new
    28
    If the judge determines on remand that Debra's affidavit is
    supported by sufficiently persuasive guarantees of
    trustworthiness to be admissible, the result will not be an
    automatic new trial.    Instead, the judge must then decide
    whether Debra's affidavit, together with the evidence offered by
    Betty Jo and Anderson, satisfies the established standard for a
    motion for a new trial.    That standard requires a showing "both
    that the evidence is newly discovered and that it casts real
    doubt on the justice of the conviction."    Commonwealth v. 
    Grace, 397 Mass. at 305
    .    The inquiry into whether the defendant has
    satisfied the new trial standard is conceptually distinct from
    the threshold inquiry into whether Debra's affidavit is
    admissible at all, although many of the same considerations that
    inform a judge's assessment of the affidavit's trustworthiness
    may well also inform the judge's assessment whether it casts
    real doubt on the justice of the conviction.7
    trial, the judge could assess their credibility as it bears on
    the trustworthiness of Debra's affidavit. Similarly, there may
    also be testimony taken from the lawyer who prepared Debra's
    affidavit, who could provide information about her physical and
    mental condition at the relevant time. The Commonwealth
    likewise could call witnesses and probe factors relating to,
    among other things, Debra's potential motives and state of mind
    at the time she gave her affidavit and before her death. For
    instance, it could be explored whether Debra had any sort of
    relationship with the defendant that might have created a motive
    for her to lie in order to support the defendant's motion for a
    new trial.
    7
    In addition to concluding that Debra's affidavit was not
    29
    To establish that evidence is "newly discovered," the
    defendant must show that the evidence was "unknown to the
    defendant or his counsel and not reasonably discoverable by them
    at the time of trial."    
    Id. at 306.
      The Commonwealth asserts
    that, regardless of whether the affidavit is admissible, it is
    not newly discovered.    The Commonwealth concedes that Debra was
    unavailable at the time of the trial, given the prosecution's
    unsuccessful efforts to locate her.     The Commonwealth, however,
    contends that Betty Jo was available at the time of trial.
    Because Betty Jo allegedly knew that her sister claimed to have
    been in the bathroom with Jackson at the time of the shooting,
    and because defense counsel chose not to call Betty Jo as a
    witness, the Commonwealth contends that the defendant has not
    met his burden of showing that the substance of Debra's
    affidavit was not reasonably discoverable at the time of the
    trial.
    admissible as a dying declaration, the judge also determined
    that Debra's statements "would not be sufficient to warrant a
    new trial" because it only "tend[s] to impeach the testimony of
    Jackson." In Commonwealth v. Cowels, 
    470 Mass. 607
    , 621 (2015),
    however, which we decided after the judge denied the defendant's
    first motion for a new trial, we clarified that "we have never
    adopted an inflexible rule that newly discovered evidence that
    merely corroborates or impeaches a witness's testimony is an
    insufficient basis for a motion for a new trial." Indeed, we
    noted that, "in rare cases, a new trial may be warranted where
    the Commonwealth's case depends so heavily on the testimony of a
    witness and where the newly discovered evidence seriously
    undermines the credibility of that witness" (citations,
    quotations, and alterations omitted). 
    Id. 30 The
    motion judge did not address the question whether the
    evidence offered by the defendant was newly discovered, likely
    because of her determination that, in any event, Debra's
    affidavit would not be admissible.     Like the issue whether
    Debra's affidavit bears persuasive assurances of
    trustworthiness, we believe that the question whether the
    substance of Debra's affidavit is newly discovered warrants an
    evidentiary hearing.     We note, for instance, that Betty Jo's
    affidavit indicates that she was "not completely truthful" with
    the police officers who questioned her because she "did not want
    to get involved in the case," and that she stated at the
    suppression hearing conducted shortly before the trial that she
    refused to speak with defense counsel.     We also have no
    information about whether Anderson was available at the time of
    the trial.    In light of these circumstances, we think that the
    answer to the question whether "reasonable pretrial diligence
    would . . . have uncovered" (quotation omitted) the information
    contained in Debra's affidavit hinges on questions of fact that
    warrant an evidentiary hearing.     Commonwealth v. Weichell, 
    446 Mass. 785
    , 799 (2006).
    We conclude by emphasizing the narrowness of the
    constitutional principle that governs this case and necessitates
    our remand.    Our decision does not signal a departure from our
    long-standing refusal to adopt a broad residual hearsay rule
    31
    modeled on the Federal rule.   In the vast majority of cases, the
    established hearsay exceptions will continue to govern the
    admissibility of hearsay evidence at most criminal trials, with
    this constitutional hearsay exception operating only in the
    rarest of cases, where otherwise inadmissible evidence is both
    truly critical to the defense's case and bears persuasive
    guarantees of trustworthiness.
    d.   Ineffective assistance of counsel based on defense
    counsel's posttrial conduct.     The defendant argues that, if this
    court concludes that Debra's affidavit is not admissible, then
    we should find that counsel provided ineffective assistance in
    failing to act immediately to preserve Debra's testimony, and
    that counsel's error caused a substantial likelihood of a
    miscarriage of justice.   Because of the inadequacy of the record
    before us at this point and because we are remanding the case
    for a determination whether Debra's affidavit is admissible
    under the standard articulated in Chambers, we decline to reach
    the defendant's ineffective assistance of counsel claim based on
    defense counsel's posttrial conduct.    If the judge on remand
    concludes that the affidavit is not admissible, the defendant
    may then bring a motion for a new trial based on defense
    counsel's allegedly ineffective posttrial conduct in handling
    the defendant's motion for a new trial.
    3.   Conclusion.   The defendant's convictions are affirmed,
    32
    as is the order denying the defendant's second motion for a new
    trial.   The order denying the defendant's first motion for a new
    trial, however, is vacated, and the case is remanded to the
    Superior Court for further consideration of that motion in a
    manner consistent with this opinion.
    So ordered.
