    Indictments found and returned in the Superior Court
    Department on June 28, 2012.
    A pretrial motion to suppress evidence was heard by Richard
    E. Welch, III, J., and the cases were tried before Howard J.
    Whitehead, J.
    David H. Mirsky (Joanne T. Petito also present) for the
    defendant.
    Marcia H. Slingerland, Assistant District Attorney, for the
    Commonwealth.
    CYPHER, J.   The defendant, Joseph Wright, appeals from two
    convictions of murder in the first degree.    He urges the
    2
    reversal of his convictions on four grounds.   First, he contends
    that the pretrial motion judge erroneously denied his motion to
    suppress statements he made to Canadian law enforcement
    officers.   Second, he argues that the trial judge committed a
    reversible error in ordering the pretrial disclosure of the
    defendant's mental health expert's report regarding the
    defendant's mental condition at the time of the crimes, which
    the prosecution had in its possession during its subsequent
    cross-examination of the defendant.    Third, the defendant argues
    that the evidence at trial demonstrates his lack of criminal
    responsibility for the murders, and relatedly, that his trial
    counsel's failure to argue a lack of criminal responsibility
    defense before the jury constitutes ineffective assistance of
    counsel.    Fourth, he argues that State police investigators
    failed to collect certain evidence relevant to his intoxication
    at the time of the crimes, thereby denying the defendant his
    right to a "complete defense."    Having considered the
    defendant's arguments, and, more broadly, "the whole case on the
    law and the facts" pursuant to our duty under G. L. c. 278, §
    33E, Commonwealth v. Howard, 
    469 Mass. 721
    , 747 (2014), we
    affirm the convictions.
    Factual and procedural background.     We recite the facts the
    jury could have found in the light most favorable to the
    3
    Commonwealth, but we reserve certain details of the facts and
    proceedings for discussion of the individual issues.
    The defendant does not dispute that he killed his mother,
    Donna Breau, and his grandmother, Melba Trahant, at their
    residence in Lynn on April 30, 2012.    Following the killings,
    the defendant drove to the Canadian border at Belleville, New
    Brunswick, where he arrived at approximately 6 P.M. on May 1,
    2012.    After hesitating in responding to questions posed by a
    Canadian border services officer about his presence in Canada,
    the defendant fled across the border, and was quickly
    apprehended by a member of the Royal Canadian Mounted police.
    The defendant subsequently confessed to the murders of his
    mother and grandmother during an interview with two Canadian
    border officers.    The defendant told the officers that he had
    slit the victims' throats and left their bodies behind a local
    elementary school.1   (Unbeknownst to the Canadian officers, the
    victims' bodies had been found at 6:45 A.M. that day on the
    grounds of the elementary school; both women appeared to have
    suffered "pretty severe" neck wounds.)
    Custody of the defendant was transferred to United States
    authorities, and in June, 2012, a grand jury returned two

    arrest and interrogation by Canadian law enforcement officers,
    as well as the defendant's pretrial motion to suppress those
    statements, for our analysis of that issue.
    4
    indictments charging the defendant with murder in the first
    degree of his mother and grandmother.   Before trial the
    defendant moved to suppress his statements to the Canadian
    authorities on the grounds that they were involuntary and that
    he had not been given his Miranda warnings, but his motion was
    denied.   The defendant was then tried before a jury in the
    Superior Court between June 10 and 23, 2014.   The prosecution
    proceeded under the theories of deliberate premeditation and
    extreme atrocity or cruelty.   The defense's theory was that,
    although the defendant admitted to the killings, they did not
    constitute murder in the first degree because the defendant had
    a "diminished capacity" due to drugs and alcohol, and therefore
    he could not have deliberately premeditated or acted with
    extreme atrocity or cruelty.
    The defendant took the stand as the sole defense witness.2
    Although the defense had, before trial, provided notice of the
    testimony of an expert psychologist who would testify as to the
    defendant's mental condition at the time of the killings, the
    defense ultimately chose not to call the expert, who had
    prepared a report, appeared on the witness list, and was
    available to testify.
    2  Before testifying, the defendant affirmed in a colloquy
    with the judge that his decision to take the stand was his own
    and that he was not pressured into doing so.
    5
    From an early age the defendant heavily abused drugs and
    alcohol.   At ten years old he began smoking marijuana, and at
    thirteen he started drinking hard alcohol.   At fifteen, and for
    approximately the next two years, the defendant was in a
    residential program for marijuana and alcohol abuse.     His
    habitual drug abuse continued into adulthood, as the defendant
    ingested (in his words) "anything [he] was able to [stick] in
    [his] face," including mushrooms, "Ecstasy," cocaine, "crack"
    cocaine, and heroin.   He also abused a variety of over-the-
    counter and prescription drugs.
    At age twenty-two the defendant became unemployed and moved
    in with his mother in her second-floor apartment in Lynn.      His
    grandmother, who was in her eighties and had a close
    relationship with the defendant, lived in the apartment on the
    first floor.   The defendant had only intermittent contact with
    his mother throughout his childhood because she was in Florida
    and in and out of jail with her own drug problems.     She
    eventually returned to Lynn when the defendant was sixteen or
    seventeen, but he avoided contact with her until he was eighteen
    or nineteen because "she wasn't there when [he] was a kid."
    Upon moving in with her, the defendant testified, "things just
    started getting out of hand" in terms of the pair's substance
    abuse, and it was "pretty much a big party."   The defendant's
    mother gave him her prescribed Klonopin, Ativan, and Wellbutrin
    6
    medications.    The defendant was also regularly smoking
    marijuana, snorting and injecting heroin, and smoking crack
    cocaine.
    The defendant testified to the details of the killings.        He
    had been abusing his mother's Klonopin virtually "nonstop" since
    his birthday on April 9.    Also, after having a cyst removed from
    his forehead four or five days before April 30, the defendant
    began hearing a voice inside his head.     On the evening of April
    30, the defendant recalled going to the liquor store and
    purchasing two forty-ounce containers of beer, which he brought
    home and drank with his mother at about 6 or 7 P.M.     Before
    leaving the apartment to purchase marijuana, the defendant
    ingested a "handful" of Klonopin.     He brought home the marijuana
    and smoked it with his mother.     His grandmother was downstairs
    in her apartment, and at some point his mother went to bed.
    While the defendant sat on a recliner in the living room of
    his mother's apartment, he heard a voice inside his head, and
    the thought of killing his mother entered his mind.     He began
    walking to the entranceway of his mother's bedroom, and the
    voice he heard was telling him to kill her.     He recalled being
    at the doorway, seeing his mother asleep on the bed, and walking
    away.     The defendant then obtained a knife from the kitchen,
    went into his mother's bedroom while she slept, and slashed her
    throat.    He did not remember if she asked for help, but did
    7
    recall she told him he was "fucked" and admitted to watching her
    "bleed[] out" on the bed.
    At some point during the night, the defendant took the same
    knife he used to kill his mother and went downstairs to his
    grandmother's apartment, where he found her in the living room.
    The defendant was not hearing any voice inside his head telling
    him to kill his grandmother, but he thought she saw blood on him
    and that she was going to call the police.    The defendant walked
    up to her from behind, put a pillow over her face, and slashed
    her throat.    She asked the defendant why he had done that, and
    died in front of him.
    The defendant awoke at some point in the early morning on
    May 1, 2012.    Not immediately recalling what had occurred, he
    was shocked to find blood on the kitchen floor; he walked into
    his mother's bedroom and found her dead with a "lot of blood,"
    and went downstairs and found his grandmother "dead on her
    couch."    The defendant "freaked out" and took more drugs and
    alcohol.   He left the bodies at a nearby elementary school and
    fled to Canada.   Following deliberations, the jury found the
    defendant guilty of the murders of both victims on the theory of
    extreme atrocity or cruelty, and the defendant was sentenced to
    consecutive life terms.     Forgoing a motion for a new trial, the
    defendant filed a timely notice of appeal in June, 2014, and the
    case was entered in this court the following year.

    Discussion.   1.   Defendant's statements to Canadian
    authorities.   The defendant first challenges his convictions on
    the ground that his statements to Canadian border officers were
    involuntary and therefore inadmissible.    The voluntariness of
    the defendant's statements was not a live issue at trial, so the
    issue was not submitted to the jury.    See, e.g., Commonwealth v.
    Sheriff, 
    425 Mass. 186
    , 193 (1997).3    Yet the defendant did move
    to suppress those statements before trial, and also objected to
    their introduction at trial through the testimony of certain
    Canadian law enforcement officers.     We therefore treat the
    defendant's argument as a claim of error in the denial of his
    pretrial motion to suppress.
    We briefly recount the relevant facts concerning the
    defendant's statements to the Canadian authorities, as found by
    the motion judge following an evidentiary hearing.4    At
    3 The defendant testified on direct examination that the
    Canadian authorities allowed him to rest before the interview,
    and did not yell, threaten, or otherwise coerce him during the
    interview. Following the close of evidence, defense counsel
    specifically asked "not to give the voluntariness" instruction
    (also known as a "humane practice" instruction), based on his
    concern that it might "water down" the requested DiGiambattista
    jury instruction, which applies where there is no recording of a
    defendant's interrogation, as here. Commonwealth v.
    DiGiambattista, 
    442 Mass. 423
     (2004). The trial judge provided
    the jury with the DiGiambattista instruction.
    4 "In reviewing a ruling on a motion to suppress, we accept
    the judge's subsidiary findings of fact absent clear error but
    conduct an independent review of his ultimate findings and
    conclusions of law" (citation and quotations omitted).
    9
    approximately 8 P.M. on May 1, 2012, the defendant was
    apprehended after illegally crossing the border into Canada --
    specifically, the port of entry at Woodstock, New Brunswick,
    which borders Houlton, Maine.     He was arrested by a member of
    the Royal Canadian Mounted police (RCMP), who read the defendant
    a "caution" that stated:     "[Y]ou need not say anything, you have
    nothing to hope from any promise or favor and nothing to fear
    from any threat whether or not you say anything.        Anything you
    say may be given in evidence.     Do you understand?"     The
    defendant indicated he understood, and said he wished to speak
    to an attorney.     This information was relayed to Canadian border
    officers at the Woodstock crossing, where the RCMP officer
    brought the defendant.     Upon his arrival, the border officers
    asked the defendant, who was in custody, to disrobe, because
    there was blood on the defendant's clothing that the officers
    wished to preserve as potential evidence.     The defendant did not
    appear to be under the influence of any drugs or alcohol, but
    informed the officers that he had smoked "a little" marijuana
    that day.
    The defendant was then taken by two border officers to an
    interview room.     The defendant was not handcuffed and appeared
    "fully oriented."     One of the officers read the defendant a
    Commonwealth v. Weaver, 
    474 Mass. 787
    , 793 (2016), cert. denied,
    
    137 S. Ct. 809
     (2017).
    10
    "secondary caution," similar to the one read to him by the RCMP
    officer, and informed him of his right under the Vienna
    Convention to speak with a member of the United States
    government.    The officer also informed the defendant of his
    right to speak with "duty counsel," an attorney paid for by
    Canada to represent someone who does not have his or her own
    attorney, and the defendant indicated he would like to speak
    with duty counsel.    The officer explained the charge the
    defendant was facing so that the defendant could inform duty
    counsel why he was being held (i.e., failing to stop and speak
    to immigration officers at the border).
    At that point the defendant began to laugh and said,
    "That's nothing, jail here or jail there, it doesn't make any
    difference."    He then asked the officers, "[D]o you want to know
    why I ran[?]"    One of the officers interrupted the defendant and
    advised him for a third time that he did not have to say
    anything and that anything he did say might be used in evidence.
    The officer then asked the defendant why he ran.     The defendant
    responded that he had killed his mother and grandmother by
    slitting their throats, and informed the officers what he had
    done with the murder weapon (the knife), where he had placed
    their bodies, and why he had committed the crimes.     After these
    responses, the defendant "slumped down in his chair, stopped
    speaking, and appeared relieved."    Throughout the confession the
    11
    defendant "was relaxed, calm, [and] never agitated," and
    understood what he was doing and what he was being asked.     The
    defendant's statements were not recorded.
    Before trial, the defendant argued that his statements
    should have been suppressed because they were not voluntary and
    the police did not give the defendant Miranda warnings before
    questioning him.    The motion judge held first that because the
    defendant's statements were given to foreign police officers,
    Miranda v. Arizona, 
    384 U.S. 436
     (1966), did not apply.     The
    judge further concluded that "all the evidence points to the
    fact that [the defendant's] statements were made voluntarily and
    knowingly and [were] the product of his own rational intellect."
    We discern no error in these conclusions.   First, we have
    previously held that Miranda does not govern interrogations
    "carried out by foreign officials in a foreign country," and
    that statements made to foreign police are admissible if they
    were voluntary.    Commonwealth v. Wallace, 
    356 Mass. 92
    , 96-97
    (1969).5   We explained that "applying the Miranda rule to foreign
    police officers will not affect their conduct, and therefore we
    decline to so extend the scope of that decision."    
    Id.
       Numerous
    courts that have more recently addressed this question have
    reached the same conclusion.   See, e.g., United States v.
    5 Wallace, like this case, involved a defendant's statements
    made to Canadian law enforcement officers. Commonwealth v.
    Wallace, 
    356 Mass. 92
    , 96-97 (1969).
    12
    Yousef, 
    327 F.3d 56
    , 145 (2d Cir.), cert. denied, 
    540 U.S. 933
    (2003) ("the law is settled that statements taken by foreign
    police in the absence of Miranda warnings are admissible if
    voluntary"); Fisher v. United States, 
    779 A.2d 348
    , 353-354
    (D.C. 2001), cert. denied, 
    534 U.S. 1095
     (2002).   "[B]ecause the
    United States cannot dictate the protections provided to
    criminal suspects by foreign nations and one of the principal
    purposes of the exclusionary rule -- deterrence of unlawful
    police activity -- is absent when foreign [officers] direct an
    interrogation, a different rule applies to statements elicited
    by foreign officials."   United States v. Abu Ali, 
    528 F.3d 210
    ,
    227 (4th Cir. 2008), cert. denied, 
    555 U.S. 1170
     (2009).   The
    defendant's statements to the Canadian authorities are
    admissible so long as they were voluntary.6
    The motion judge did not err in concluding that the
    defendant's statements were indeed voluntary.   "A voluntary
    statement is one that is the product of a rational intellect and
    6 While "courts recognize two exceptions to the general rule
    regarding the application of Miranda . . . in a foreign
    jurisdiction" -- (1) "where the investigatory conduct is so
    inconsistent with our notions of due process that it 'shocks the
    conscience' of a [United States] court," and (2) "when a foreign
    officer acts as an agent of [United States] law enforcement"
    (citation omitted), Fisher v. United States, 
    779 A.2d 348
    , 354
    (D.C. 2001), cert. denied, 
    534 U.S. 1095
     (2002) -- neither
    exception applies here. The first is plainly not at issue, and
    as for the second, the pretrial motion judge specifically found
    that the Canadian authorities were not acting as agents for
    United States law enforcement officers.
    13
    a free will, and not induced by physical or psychological
    coercion" (citation and quotations omitted).    Commonwealth v.
    Monroe, 
    472 Mass. 461
    , 468 (2015).   As mentioned, the motion
    judge found that there were no signs the defendant was
    intoxicated or otherwise did not understand what he was doing or
    being asked; the judge also found no evidence of "trickery,"
    "physical distress," or "that [the defendant] was made any
    promises or any threats."   The defendant does not dispute those
    factual findings (nor do we discern error in them), but he
    highlights the fact that the interrogation continued after he
    invoked his right to speak with duty counsel.   This argument is
    unavailing, as the requirement that police halt questioning
    after an individual states he or she wishes to speak with an
    attorney stems from Miranda, 
    384 U.S. at 474
    , see Commonwealth
    v. Obershaw, 
    435 Mass. 794
    , 800 (2002), which does not apply
    here.7
    2.   Disclosure of expert report to the prosecution.
    Defense counsel clarified before trial that the defense theory
    would be based on the defendant's "diminished capacity" due to
    drug and alcohol abuse.   Six weeks before jury selection, the
    defense offered its notice of expert witness, stating that it
    7 Hence, there was no error in the motion judge's conclusion
    that "the fact that [the defendant] had not yet talked to a
    lawyer does not in [any way] undermine [the] findings that . . .
    the evidence shows beyond a reasonable doubt that he made these
    statements voluntarily."
    14
    would call a psychologist, Robert H. Joss, to testify about the
    defendant's mental condition at the time of the crimes.8   By this
    time Joss had already prepared a report on the defendant's
    behalf, which included descriptions of "statements made by the
    defendant relevant to the issue of [his] mental condition" at
    the time of the killings, along with Joss's "opinions as to the
    defendant's mental condition."   Mass. R. Crim. P. 14 (b) (2) (B)
    (iii), as appearing in 
    463 Mass. 1501
     (2012).
    The Commonwealth responded a week later by filing a motion
    for reciprocal discovery regarding the defense expert, seeking,
    in pertinent part, "[n]otice as to whether . . . Joss intends to
    rely upon any statements of the defendant as the basis of his
    opinion or testimony at trial," and stating that if so, "the
    Commonwealth is entitled to an independent examination of the
    defendant" pursuant to Mass. R. Crim. P. 14 (b) (2) (B).     The
    motion was "allowed as to whether . . . Joss intends to rely
    upon statements of the defendant"; the ruling further stated
    8 The notice advised that the defendant would call Robert H.
    Joss to testify that "at the time of the offenses [the
    defendant] was undergoing an unusual pattern of indiscriminate
    substance abuse . . . and if not for this long history of drug
    abuse the killing of his mother and grandmother would not have
    happened." Joss would further testify that "[the defendant] was
    experiencing the effects of a drug induced psychosis and
    dissociative experiences related to his mother[']s abandonment
    of him at the age of two at the time of the killings." The
    notice did not clarify, as it was required to, whether Joss
    "intend[ed] to rely in whole or in part on statements of the
    defendant as to his . . . mental condition." Mass. R. Crim. P.
    14 (b) (2) (A) (iii), as appearing in 
    463 Mass. 1501
     (2012).
    15
    that "[i]f [the defendant] provides notice that he intends to
    offer expert testimony as to his mental state based in part on
    his statements[,] the Commonwealth may request a [rule] 14 (b)
    (2) (B) examination" of the defendant by a court-appointed
    examiner.
    The record does not reflect that the defense responded to
    the motion judge's order, however, and the prosecution did not
    ultimately seek an independent examination of the defendant.
    Before jury selection, on the first day of trial proceedings,
    the defense repeated to the trial judge its intention to call
    Joss as an expert witness.    The judge then asked the
    prosecution, "[A]re you going to have somebody?" -- presumably
    referring to an expert of its own -- to which the prosecution
    responded, "No."    Joss appeared on the witness list read to
    potential jurors.   Following jury empanelment and just before
    opening statements, the prosecution said that while it did not
    seek an independent examination of the defendant, it did seek
    access to Joss's report.     Over the defendant's objection, the
    judge "order[ed] that the report be turned over now, where there
    has been a commitment by the defense to the diminished capacity
    [of the defendant]."
    The defendant argues that this order violated Mass. R.
    Crim. P. 14 (b) (2), which governs discovery related to expert
    testimony on the issue of the defendant's "mental condition."
    16
    The prosecution should never have received Joss's report, the
    defendant contends, because it never sought an independent,
    court-ordered examination of the defendant under rule
    14 (b) (2) (B), which, he argues, is a prerequisite to the
    rule's requirement that a defendant provide his expert report to
    the prosecution.   The defendant concludes that the prosecution's
    later use of Joss's report during its cross-examination of him
    violated his State and Federal rights against self-
    incrimination, and warrants reversal of his convictions.9
    "As our task is to interpret a rule of criminal procedure,
    we begin with the plain language of the rule."   Commonwealth v.
    Hanright, 
    465 Mass. 639
    , 641 (2013).   Rule 14 (b) (2) provides
    9 As mentioned, the defendant took the stand in his own
    defense at trial. On direct examination he did not recount the
    details of the killings themselves. He testified that he did
    not immediately remember what happened between the time that he
    returned to his mother's apartment with marijuana, and when he
    woke up to find his mother and grandmother dead. The defendant
    stated that "about a week later" he "started really thinking
    hard," and remembered that he had been awake for "two days
    straight without sleeping," and that he heard a voice in his
    head "telling [him] to just kill [his] mother." He also
    recalled getting rid of the victims' bodies.
    Before cross-examining the defendant, the prosecution
    sought permission to impeach the defendant with statements he
    made to Joss, which were incorporated into Joss's report. The
    judge ruled that while the prosecution could not introduce the
    statements themselves to impeach the defendant, it could use its
    knowledge of the content of those statements when formulating
    its cross-examination. While it is not entirely clear to what
    extent the prosecutor's knowledge of the contents of Joss's
    report guided his cross-examination of the defendant, the
    defendant did more fully recount the details of the killings
    during cross-examination.

    the "[s]pecial [p]rocedures" governing pretrial discovery
    regarding defenses based on a criminal defendant's "[m]ental
    [h]ealth [i]ssues."10   Subdivision (b) (2) (A) requires a
    defendant to notify the prosecution if he "intends at trial to
    raise as an issue his or her mental condition at the time of the
    alleged crime, or . . . intends to introduce expert testimony on
    [his or her] mental condition at any stage of the proceeding."
    The next subdivision, (b) (2) (B), states that where it appears
    (based on [1] the defendant's notice of expert testimony, [2]
    "subsequent inquiry by the judge," or [3] "developments in the
    case") that the defendant's expert will rely on "statements of
    the defendant as to his or her mental condition . . . , the
    court, on its own motion or on motion of the prosecutor, may
    order the defendant to submit to an examination" consistent with
    10As a preliminary matter, we are satisfied that the
    defendant's "diminished capacity" defense, which was to include
    expert testimony from a psychologist stating that the defendant
    was experiencing "a drug induced psychosis" at the time of the
    crime, implicates the defendant's "mental condition" such that
    it is subject to the "[s]pecial [pretrial discovery]
    [p]rocedures" of Mass. R. Crim. P. 14 (b) (2), as appearing in
    
    463 Mass. 1501
     (2012). See Commonwealth v. Newton N., 
    478 Mass. 747
     (2018), citing Mass. R. Crim. P. 14 (b) (2) (A) ("due to the
    complex nature of mental impairment, which is often presented at
    trial through expert testimony, we require defendants to provide
    the same notice regarding their intent to raise an issue of
    mental impairment at trial as we do their intent to raise a
    defense of criminal responsibility"). "[A]ll procedures and
    provisions applicable to such discovery are set out in rule
    14 (b) (2)," and are not subject to the "automatic and
    discretionary [discovery] provisions" of rule 14 (a).

    the detailed provisions of Mass. R. Crim. P. 14 (b) (2) (B) and
    (C).11
    The same subdivision, (b) (2) (B) -- specifically, part
    (iii) -- also establishes a regime for the disclosure of mental
    health expert reports.   This disclosure occurs, in pertinent
    part, "after the defendant expresses the clear intent to raise
    as an issue his or her mental condition, [and] the judge is
    satisfied that (1) the defendant intends to testify, or (2) the
    defendant intends to offer expert testimony based in whole or in
    part on statements made by the defendant as to his or her mental
    condition at the relevant time."   Mass. R. Crim. P. 14 (b) (2)
    (B) (iii) (c).   While the paragraph in which this language
    appears refers to the disclosure of the court-appointed
    "examiner's report," the next paragraph clarifies that "[a]t the
    time [the examiner's report] is disclosed to the parties, the
    defendant shall provide the Commonwealth with a report of the
    defense psychiatric or psychological expert(s) as to the mental
    condition of the defendant at the relevant time."   Id.12
    11"As a practical matter, it is the prosecutor who
    recommends the expert psychiatrist for appointment as the
    examiner. We have recognized the court-appointed examiner as an
    agent of the prosecution." Sliech-Brodeur, 457 Mass. at 318
    n.23.
    12This provision ordering the disclosure of a defense
    expert's report was inserted as part of the 2012 amendments to
    the rule, following this court's opinion in Sliech-Brodeur, 457
    Mass. at 324-326. Sliech-Brodeur involved a pretrial discovery
    19
    The defendant argues that because rule 14 (b) (2) (B) (iii)
    contemplates an exchange of reports from both sides' experts --
    one by the defense ("a report of the defense psychiatric or
    psychological expert") and another by the court-ordered examiner
    ("examiner's report") -- in a case where the prosecution has not
    sought a court-ordered examination, as here, a defendant has no
    independent duty to disclose his or her expert's report.     We
    disagree.   The fact that the rule discusses a defendant's
    disclosure obligation in tandem with that of the court-appointed
    examiner simply reflects the typical course in cases where a
    defendant pursues a mental health defense:   after the defendant
    expresses his or her intent to pursue that defense, the
    prosecution will seek an independent examination regarding the
    defendant's mental condition at the time of the crime.    Such was
    the sequence of events in Sliech-Brodeur, 457 Mass. at 310,
    order requiring the defendant to furnish his mental health
    expert's notes and materials to the Commonwealth, who had
    secured an independent expert; the Commonwealth provided the
    defense materials to its expert, who relied on them when forming
    his own opinion about the defendant's criminal responsibility.
    Id. at 322. The court deemed this reversible error on the
    grounds that "nothing in [rule 14 (b) (2)] obligates a
    defendant, before trial, to provide the Commonwealth's expert
    . . . with copies of her own expert witness's notes and other
    materials." Id. at 321. Responding to "'confusion' surrounding
    the sequence of production of mental health experts' materials,"
    the court also provided for the amendment of rule 14 (b) (2) "to
    require the defendant's expert to produce to the prosecution a
    report that includes the defense expert's opinion [as to the
    defendant's mental condition] and the bases and reasons for this
    opinion." Id. at 325-326.
    20
    which resulted in this provision.    While the rule affords the
    prosecution the opportunity to obtain an independent examiner,
    we do not interpret it to impose on the prosecutor an obligation
    to do so or otherwise be denied access to the defense expert's
    report.13
    Mental health defenses like the instant one represent
    "complex issues for which the prosecutor should have time to
    prepare."   Reporter's Notes (2012) to Rule 14 (b) (2),
    Massachusetts Rules of Court, Rules of Criminal Procedure, at
    197 (Thomson Reuters 2016).   See Sliech-Brodeur, 457 Mass. at
    325 (explaining "our view . . . that the Commonwealth should
    have advance notice of complex mental health issues that the
    defendant intends to raise as part of his or her defense").       An
    effective "[r]ebuttal of [such defenses] requires a degree of
    expertise on the part of a cross-examiner that can only be
    gained through pretrial research."   Reporter's Notes (Revised,
    2004) to Rule 14 (b) (2), supra at 195.    This includes access to
    the defense expert's report, without which the prosecution
    cannot effectively impeach the expert's or the defendant's own
    testimony during cross-examination, thereby undermining "rule 14
    13That the court-appointed examiner is an optional, not
    mandatory, component of a prosecutor's trial strategy is
    bolstered by the plain language of the rule, which states that
    the court "may order the defendant to submit to an examination,"
    not that it "shall" always do so (emphasis added). Mass. R.

    (b) (2) (B)'s truth-seeking function."    Hanright, 465 Mass. at
    644.    See Commonwealth v. Durham, 
    446 Mass. 212
    , 230, cert.
    denied, 
    549 U.S. 855
     (2006) (Marshall, C.J., dissenting)
    (recognizing "the importance that cross-examination plays in the
    'fact finder's assessment of the truth'" [citation omitted]).
    Accordingly, consistent "with the trend of increased discovery
    in criminal cases," Sliech-Brodeur, supra at 325, we interpret
    rule 14 (b) (2) (B) (iii) to impose on a defendant an
    independent duty to disclose his or her expert's report to the
    prosecution "after the defendant expresses the clear intent to
    raise as an issue his or her mental condition," and where "the
    judge is satisfied that (1) the defendant intends to testify, or
    (2) the defendant intends to offer expert testimony based in
    whole or in part on statements made by the defendant as to his
    or her mental condition at the relevant time."   Mass. R. Crim.
    P. 14 (b) (2) (B) (iii).14
    We disagree with the defendant that the required
    14
    disclosure of his mental health expert's report to the
    prosecution implicates his right against self-incrimination. As
    Chief Justice Gants (then Associate Justice) observed in his
    dissent in Sliech-Brodeur, 457 Mass. at 340, that right "does
    not apply to a defendant's statements to the psychiatrist [or
    psychologist] retained by his attorney because these statements
    were not compelled by the Commonwealth or the court; the
    defendant voluntarily chose to speak to his defense expert."
    "Nevertheless," the dissent explained, "disclosure to the
    prosecution of the defense expert's reports and statements must
    still wait until the defendant decides whether the expert will
    testify at trial based in whole or in part on the defendant's
    statements to the expert, because, until that decision is made,
    22
    Here, the judge ordered the defendant to turn over his
    expert's report to the prosecution based on his conclusion that
    "there has been a commitment by the defense to the diminished
    capacity" of the defendant.   This was not in error.   By this
    stage of the proceedings the defendant had expressed the "clear
    intent to raise as an issue his . . . mental condition," Mass.
    R. Crim. P. 14 (b) (2) (B) (iii), having explained before jury
    empanelment that he was "seeking a murder two conviction . . .
    based on diminished capacity," and that the defense would
    include "psychiatric testimony."   And as discussed, over a month
    before jury selection the defendant had filed his notice of
    expert witness, informing the prosecution (and the judge) that
    the defense would call Joss to testify "that at the time of the
    offenses [the defendant] was undergoing an unusual pattern of
    indiscriminate substance abuse" and "was experiencing the
    effects of a drug induced psychosis" that led to the killing of
    his mother and grandmother.   Joss then appeared on the list of
    potential witnesses in the case.   On these bases, the judge
    reasonably concluded that either (1) "the defendant intend[ed]
    to testify," or, more likely, (2) "the defendant intend[ed] to
    the defendant's statements to a defense expert retained by his
    attorney are protected by the attorney-client privilege.
    Reports and statements arising from such communications, while
    not within the compass of a defendant's privilege against self-
    incrimination, are protected by the work product doctrine"
    (emphasis in original). Id. at 341.
    23
    offer expert testimony based in whole or in part on statements
    made by the defendant as to his . . . mental condition at the
    relevant time."   Id.15
    3.   Lack of criminal responsibility and ineffective
    assistance of counsel.     The defendant also seeks reversal of his
    convictions on the grounds that he lacked criminal
    responsibility for the murders; relatedly, he argues that trial
    counsel's failure to present this argument to the jury
    constitutes ineffective assistance of counsel.    In support of
    these positions the defendant relies exclusively on Joss's
    report, which he contends "contains clear evidence that [the
    defendant] lacked criminal responsibility" for the murders.
    We reject both arguments for essentially the same reason:
    having reviewed Joss's report, which is impounded, we simply
    find no support for the defendant's position that he lacked
    criminal responsibility.    To the contrary, Joss concluded that
    15 Rule 14 (b) (2) (B) (iii) vests a trial judge with
    discretion when making this determination, given that it
    conditions disclosure of the defense expert's report on the "the
    judge [being] satisfied" that the defense will include either
    the defendant's testimony or an expert's testimony based on the
    defendant's statements (emphasis added). Such discretion is
    necessary in cases such as this, where despite being ordered to
    do so twice -- first, pursuant to Mass. R. Crim. P. 14 (b) (2)
    (A) (iii), in the defendant's notice of a mental health defense,
    and again by the court order granting the prosecution's motion
    for reciprocal discovery regarding the defense expert -- the
    defense apparently failed to clarify before trial whether Joss
    would be relying on the defendant's statements regarding his
    mental condition.
    24
    the defendant did not have a mental disease or defect –- an
    essential element of a defense based on lack of criminal
    responsibility.    See Commonwealth v. McHoul, 
    352 Mass. 544
    , 546-
    547 (1967) ("A person is not responsible for criminal conduct if
    at the time of such conduct as a result of mental disease or
    defect he lacks substantial capacity either to appreciate the
    criminality . . . of his conduct or to conform his conduct to
    the requirements of the law" [emphasis added]).    Rather, Joss
    concluded that the "source" of the defendant's impaired mental
    state at the time of the killings "was his ingestion of multiple
    drugs in an abusive way in the days and hours leading up to the
    [killings]."    This weighs strongly against the viability of a
    defense of lack of criminal responsibility, because the
    "[v]oluntary consumption of alcohol or drugs . . . do[es] not
    qualify as [a] 'mental disease[] or defect[]' in the McHoul
    formulation; as a result, a defendant whose lack of substantial
    capacity is due solely to one of these conditions, and not to
    any mental disease or defect, is criminally responsible"
    (citation omitted).    Commonwealth v. DiPadova, 
    460 Mass. 424
    ,
    431 (2011).16   Contrast Commonwealth v. Mutina, 
    366 Mass. 810
    ,
    16In light of Joss's conclusion that the defendant's drug
    consumption was the source of his impairment, it is immaterial
    that Joss erroneously relied on the definition of "mental
    illness" under 104 Code Mass. Regs. § 27.05(1), which relates to
    involuntary commitment.
    25
    811-817 (1975) (reversing conviction of murder in first degree
    where defendant presented "very strong evidence of his lack of
    criminal responsibility" consisting of, among other things,
    testimony of two psychiatric experts who concluded defendant's
    schizophrenia prevented him from conforming his conduct to law,
    and where prosecution failed to present "any affirmative
    evidence of the defendant's sanity").17
    We similarly reject the defendant's contention that trial
    counsel was ineffective for failing to present a lack of
    criminal responsibility defense.   "The defendant did not file a
    motion for a new trial and therefore rests his claim of
    ineffective assistance of counsel solely on the trial record.
    Such ineffective assistance of counsel claims are 'the weakest
    form of such a challenge' because they lack 'any explanation by
    trial counsel for his actions.'"   Commonwealth v. Griffin, 
    475 Mass. 848
    , 857-858 (2016), quoting Commonwealth v. Peloquin, 437
    17We also reject the defendant's suggestion that it was the
    prosecution's burden to demonstrate that the defendant was
    criminally responsible. Only where a defendant "asserts a
    defense of lack of criminal responsibility and there is evidence
    at trial that . . . would permit a reasonable finder of fact to
    have a reasonable doubt whether the defendant was criminally
    responsible" does the prosecution "bear[] the burden of proving
    beyond a reasonable doubt that the defendant was criminally
    responsible." Commonwealth v. Lawson, 
    475 Mass. 806
    , 811
    (2016), quoting Commonwealth v. Keita, 
    429 Mass. 843
    , 849–850
    (1999). As mentioned, the defense did not assert a lack of
    criminal responsibility defense here; to the contrary, just
    before opening statements, defense counsel reiterated that it
    was "not bringing forward a criminal responsibility defense"
    (emphasis added).
    
    26 Mass. 204
    , 210 n.5 (2002).   "Examining this claim under G. L.
    c. 278, § 33E, 'we review the trial record alone to determine
    whether a defense counsel's strategic or tactical decision
    questioned on appeal was manifestly unreasonable when made and,
    if so, whether the unreasonable decision resulted in a
    substantial likelihood of a miscarriage of justice.'"     Griffin,
    supra at 858, quoting Commonwealth v. Brown, 
    462 Mass. 620
    , 629
    (2012).
    There were clear reasons for not pursuing a lack of
    criminal responsibility defense at trial.    Compare Commonwealth
    v. LaCava, 
    438 Mass. 708
    , 714 (2003) (where counsel's expert
    opined defendant did not have mental disease or defect, not
    unreasonable for counsel to consider that opinion as "serious
    impediment" to insanity defense).   In addition to Joss's
    conclusions, defense counsel also clarified before jury
    selection -- "[j]ust so the record is clear" -- that he had
    "talked to [the defendant] about [the defense's trial strategy]
    at length" and that "diminished capacity by reason of alcohol
    and drugs" was the defense that the defendant had "agreed to."
    The strategic focus on the defendant's substance abuse at the
    time of the killings was therefore not unreasonable and presents
    no likelihood of a miscarriage of justice.
    4.    Alleged substandard evidence collection.   Last, the
    defendant contends that he was denied his constitutional right
    27
    to a "meaningful opportunity to present a complete defense,"
    California v. Trombetta, 
    467 U.S. 479
    , 485 (1984), based on
    State police investigators' failure to collect evidence that may
    have been tied to the defendant's drug use -- specifically, a
    number of prescription pill bottles in his grandmother's
    apartment, and certain small plastic bags in his mother's
    apartment that were consistent with drug packaging.   According
    to the defendant, this evidence "was potentially useful to
    support [his] defense that he possessed a diminished capacity to
    form the required intent for first degree murder due to his
    intoxication by drug use."
    We reject the defendant's argument, primarily because the
    potentially exculpatory value of this evidence was not apparent
    at the time of the State police investigation.   See Trombetta,
    
    467 U.S. at 488-489
     ("Whatever duty the Constitution imposes on
    the States to preserve evidence, that duty must be limited to
    evidence that might be expected to play a significant role in
    the suspect's defense.   To meet this standard of constitutional
    materiality, . . . evidence must . . . possess an exculpatory
    value that was apparent before the evidence was destroyed
    [footnote omitted]").    The significance of the defendant's drug
    use did not come to light until nearly two years after the
    police's investigation in this case, when the defendant first
    raised his intoxication-based defense.    There is also no
    28
    indication that the police intended to conceal such evidence
    here, given that photographs from their investigation display
    the prescription pill bottles and plastic bags.   "While the
    prosecution remains obligated to disclose all exculpatory
    evidence in its possession, it is under no duty to gather
    evidence that may be potentially helpful to the defense."
    Commonwealth v. Lapage, 
    435 Mass. 480
    , 488 (2001).
    Moreover, the jury were not, as the defendant suggests,
    entirely precluded from considering this evidence, as those
    photographs were submitted to the jury as exhibits.   And as was
    the defendant's right under Commonwealth v. Bowden, 
    379 Mass. 472
    , 485-486 (1980), the defendant raised the issue of the
    adequacy of the police's evidence collection at trial, and the
    judge did not preclude the jury from considering those points
    when deciding whether reasonable doubt existed as to the
    defendant's guilt.   See Commonwealth v. O'Brien, 
    432 Mass. 578
    ,
    590 (2000) ("Bowden simply holds that a judge may not remove the
    issue from the jury's consideration").
    5.   Review under G. L. c. 278, § 33E.   We have carefully
    reviewed the entire record pursuant to our duty under G. L. c.
    278, § 33E, and we discern no reason to order a new trial or to
    reduce the convictions of murder in the first degree to a lesser
    degree of guilt.
    Judgments affirmed.
