    Indictment found and returned in the Superior Court
    Department on April 2, 2010.
    The case was tried before David A. Lowy, J.
    Robert S. Sinsheimer (Lisa Parlagreco with him) for the
    defendant.
    David F. O'Sullivan, Assistant District Attorney, for the
    Commonwealth.
    HINES, J.   In March, 2012, a Superior Court jury convicted
    the defendant, Craig Mulgrave, of murder in the first degree on
    the theory of extreme atrocity or cruelty in the stabbing death
    2
    of his wife, Christina Mulgrave.1    On appeal the defendant
    asserts that the judge erred in certain evidentiary rulings that
    violated his right to due process under the United States
    Constitution and the Massachusetts Declaration of Rights:
    (1) admitting in evidence as an excited utterance a cellular
    telephone text message sent by the victim; (2) granting the
    Commonwealth leave to present general evidence that the
    defendant made statements, which previously were suppressed, to
    impeach proffered evidence that he was noncommunicative; and (3)
    excluding the proffered testimony of a defense expert witness.
    The defendant also argues error in the jury instructions on
    diminished capacity.    We discern no error in the judge's
    evidentiary rulings or instructions to the jury.     We decline to
    exercise our authority pursuant to G. L. c. 278, § 33E, and
    affirm the defendant's convictions.
    1.   Background.   a.   The Commonwealth's case.   The jury
    could have found the following facts.     The defendant and the
    victim were married in Jamaica in July, 2008.     The two had met
    while the victim was on vacation in Jamaica, where the defendant
    had lived.   In October, 2009, the defendant obtained a visa and
    moved to Las Vegas, Nevada, to join the victim.     The couple
    1
    The Commonwealth also had proceeded under a theory of
    deliberate premeditation, but the jury did not find the
    defendant guilty under that theory.
    3
    moved to Haverhill one or two months later, where they would be
    closer to the victim's two children and her sister.
    The victim's sister and son testified that the defendant
    was depressed and frustrated that he was unable to find
    employment.   In February, 2010, the victim told her sister that
    there were problems in the marriage and that she had asked the
    defendant to go back to Jamaica, but he would not leave.       Two
    letters were read in evidence, one from the victim to the
    defendant and the other his response.    The victim's letter
    expressed her difficulties with the marriage and asked the
    defendant either to make the marriage work or to separate.      The
    defendant responded by also expressing his unhappiness in the
    marriage and telling her he felt "unhappy, depressed, without a
    job, unemployed, dependent on [her] for everything."   The
    defendant expressed his love for her and said that he wanted to
    "make this right."
    On February 7, 2010, the day of the National Football
    League's Super Bowl, the couple hosted the victim's family for
    dinner at their apartment.    The victim's son, Evan McCain,
    testified that the defendant left the house during the party and
    went out walking "all day."   The next evening, the victim came
    home to find the defendant unconscious and lying on the floor
    with a string tied into a noose around his neck, a knife tucked
    into the waistband of his pants, and a bottle of alcohol nearby.
    4
    The victim, a nurse, took a photograph of the defendant but did
    not call for medical care.   She sent Evan a text message, which
    prompted him to come over about ten minutes later.   The victim
    and Evan stood over the defendant talking for about ten minutes,
    during which time the defendant never responded or acknowledged
    their presence.   Evan testified that the defendant "drank a
    bunch of liquor" that evening.   He left the defendant a
    handwritten note expressing his disapproval.
    The following day, on February 9, the victim had an
    interview at Lowell General Hospital and, thereafter, went to
    her sister's house.   During this visit, the victim told her
    sister about the incident the prior evening.   The sister asked
    the victim to stay at the sister's home that evening.      The
    victim, however, "was adamant about going home to handle her
    business" and left at about 1 P.M. for the forty-minute drive to
    her home.   Two hours later, at 3:03 P.M., the victim sent a text
    message to Evan stating, "He is threatening to kill me I am
    scared he said if I pick up the phone he will kill me."      Six
    minutes after that, at 3:09 P.M., she telephoned 911 and
    frantically reported that her husband was stabbing her.
    A sergeant with the Haverhill police department arrived at
    the couple's apartment within two minutes of the 911 call.         As
    the sergeant entered the walkway to the apartment building, he
    heard a female screaming from one of the upstairs apartments.
    5
    He ran up the stairs and entered the apartment on the left side
    of the hallway.   A few seconds later, a man came out of the
    apartment on the right side of the hallway.    The sergeant asked
    him if he heard anything, and the man, later identified as the
    defendant, responded, "It's in here.   I just killed my wife."
    The defendant was standing at the door to the apartment he
    shared with the victim; he was covered in blood and holding a
    knife.   The defendant complied with the sergeant's requests to
    drop the knife and get down on the floor.     After the defendant
    was handcuffed, the sergeant asked him, "Where is she?," and he
    motioned toward the office in the front of the apartment.
    Inside the office, the victim was lying on her left side on
    the floor in a pool of blood.   Emergency medical technicians
    (EMTs) arrived and found the victim with a weak pulse and barely
    breathing.   The first attempt to ventilate the victim was
    unsuccessful because air from a breathing tube placed through
    the victim's mouth escaped from a stab wound in her neck.      A
    second tube was inserted directly into the stab wound and down
    into the lungs.   As the EMTs continued to render aid to the
    victim, they transported her to Merrimack Hospital, where she
    was pronounced dead shortly after arrival.
    An autopsy revealed twelve stab wounds, twelve incise
    wounds, and miscellaneous blunt force injuries.     Of the stab
    wounds, nine were to her torso, one to her left arm, one to her
    6
    right arm, and one to her right shin.    Three of the stab wounds
    penetrated her lungs, two penetrated her liver, and a stab wound
    in her neck penetrated her trachea.     The medical examiner who
    performed the autopsy testified that the specific cause of death
    was blood loss and puncture injuries to the lung and trachea,
    which inhibited the body's ability to oxygenate.     The crime
    scene analyst who inspected the apartment testified that the
    location of the blood inside the office demonstrated that the
    victim was upright when some of the stab wounds were inflicted
    and was lying down or very low to the ground when other stab
    wounds were inflicted.   The knife that the defendant was holding
    when the sergeant arrived had the victim's blood on it and the
    defendant's fingerprint on the handle.
    The defendant was arrested at the scene and taken to the
    Haverhill police station.   He was wearing the same clothes as
    during the incident the prior evening and the string was still
    tied around his neck as a noose.   The patrolman who transported
    the defendant testified that the defendant had no alcohol odor,
    no difficulty walking, and no difficulty getting into or out of
    the cruiser.   A bottle of rum, approximately two-thirds full,
    and several prescription medication bottles containing pills
    were seized from the apartment after the stabbing.
    b.   The defendant's case.   The defendant conceded guilt as
    to murder in the second degree but argued that depression
    7
    rendered him incapable of the elevated mental state required for
    murder in the first degree.   He introduced the testimony of
    three mental health experts and his cousin.   The experts all had
    experience working with depression and explained the various
    stressors that could worsen depression symptoms.    Specifically,
    the experts noted that unemployment, cultural transition, and
    breakdown of a marriage can intensify depression.   The
    defendant's cousin testified that she talked to him about once a
    week while he was in Las Vegas, but hardly at all once he was in
    Massachusetts.   She stated that it was a big opportunity for the
    defendant to go to the United States and that he would have
    looked like a failure if he had returned to Jamaica.
    The defendant's first expert, Ronald P. Winfield, a
    psychiatrist, did not interview the defendant but explained that
    depression is an imbalance in brain chemicals that can cause
    unusual brain function, especially when triggered by stressors.
    Two additional experts interviewed the defendant multiple times
    and diagnosed him with a major depressive disorder at the time
    of the stabbing.   Both experts, Robert H. Joss, a forensic
    psychologist, and Elizabeth Davis, a psychiatrist, opined that
    the defendant lacked the capacity to deliberately premeditate or
    to act with extreme atrocity or cruelty because of his
    depression.
    8
    Doctors Joss and Davis reviewed the defendant's medical
    records from before the stabbing, which showed that the
    defendant was diagnosed on December 22, 2009, with depression
    with anxiety, and was prescribed Celexa, an antidepressant.      The
    record of the appointment references tearfulness, suicidal
    ideation, and anxiety on the part of the defendant.   Based on
    the number of pills remaining in the Celexa bottle found in the
    apartment, the defendant was not taking this medication as
    directed, rendering the drug ineffective in ameliorating his
    symptoms.   During his interviews of the defendant, Dr. Joss
    observed that the defendant appeared depressed, weary, and
    without much energy.   Doctor Joss opined that the defendant was
    not faking depression because his prearrest medical records were
    consistent with his symptoms after the stabbing.
    Doctors Joss and Davis testified that they would have
    considered immediate psychiatric hospitalization of the
    defendant if they had found him in the state he was in the
    evening before the stabbing.   The defendant told the experts
    that, on the night before the stabbing, he consumed an excessive
    amount of alcohol and ingested pills.2   Doctor Davis opined that
    the defendant's actions on the night before the stabbing
    2
    These statements were not admitted for their truth but
    only as information on which the experts based their opinions.
    9
    indicated that he was in the "throes of making a suicide
    attempt."
    c.      The Commonwealth's expert.   In rebuttal, the
    Commonwealth called Martin Kelly, a psychiatrist who evaluated
    the defendant and reviewed medical records, including the
    reports from Drs. Joss and Davis.     Doctor Kelly opined that the
    defendant did not suffer from any mental defect or disease at
    the time of the stabbing; instead, he had situational or
    reactive depression.    He described situational or reactive
    depression as a psychological condition, not a mental disease.
    He further explained that this condition is time limited and
    occurs after some sort of loss, such as a breakup of a
    relationship, unemployment, or cultural adjustment.
    d.      Excluded evidence.   Prior to trial, a motion judge
    granted the defendant's motion to suppress statements made to
    police shortly after booking.     The motion judge concluded that
    the statements were made in violation of the Fifth Amendment to
    the United States Constitution and art. 12 of the Massachusetts
    Declaration of Rights.     At trial, however, the defendant sought
    to introduce evidence, through cross-examination of a police
    officer, that he was silent and noncommunicative during booking
    as a factor demonstrating diminished capacity.      The Commonwealth
    argued that such testimony would open the door to allow the
    suppressed statements to be admitted.     The trial judge noted
    10
    that the purpose of the rebuttal would be to show the
    defendant's capacity to answer questions, not the content or
    truth of the statements, and indicated that he would be
    inclined, if the defendant elicited such testimony, to allow the
    Commonwealth to introduce evidence about the number of questions
    asked and the defendant's manner and demeanor in answering the
    questions.   The fact that the statements were made, but not the
    content of the statements, would be admitted.   The defendant
    declined to introduce the evidence in light of that ruling.
    The defendant also sought to introduce the testimony of a
    fourth medical expert, William Alan Stuart, an emergency
    medicine physician.   The defendant intended to have Dr. Stuart
    testify to the effects of combining Celexa and alcohol and that
    the defendant's actions the night before the stabbing
    constituted a suicide attempt.   Further, this proposed testimony
    would have included the witness's opinion that he too would have
    commenced an involuntary commitment if he had been aware of the
    events occurring the evening before the stabbing.
    After conducting a voir dire, the judge denied the
    defendant's request to introduce testimony from this expert.
    The judge excluded the testimony on the following grounds:    (1)
    the proposed testimony was cumulative, as Dr. Davis already had
    opined that the defendant made a suicide attempt; (2) the
    proposed testimony had only limited relevancy, because the jury
    11
    could infer that the defendant was suicidal without expert
    testimony; (3) the jury likely would be confused as to the
    relevant time frame (the night before the stabbing or the day of
    the stabbing) in which to consider the defendant's mental state;
    and (4) the testimony, to the extent that it focused on what
    Evan and the victim should or should not have done on finding
    the defendant on the evening before the stabbing, would cause
    undue prejudice.
    2.    Discussion.   a.   Evidentiary issues.   i.   Text message.
    The defendant argues that the judge erred in admitting the
    content of the text message sent by the victim to her son
    approximately six minutes before she telephoned 911.      The judge
    reasoned that the written statement, although hearsay, was
    admissible under the spontaneous utterance exception to the
    hearsay rule.   Mass. G. Evid. § 803(2) (2015).     The defendant
    objected to the admission of the text message, so we review for
    prejudicial error.   Commonwealth v. Sleeper, 
    435 Mass. 581
    , 590
    (2002).
    Under our rules, admissibility under the spontaneous
    utterance exception requires that (1) "there is an occurrence or
    event 'sufficiently startling to render inoperative the normal
    reflective thought processes of the observer'"; and (2) the
    statement was "a spontaneous reaction to the occurrence or event
    and not the result of reflective thought."     Commonwealth v.
    12
    Irene, 
    462 Mass. 600
    , 606-607, cert. denied, 
    133 S. Ct. 487
    (2012), quoting Commonwealth v. Santiago, 
    437 Mass. 620
    , 623
    (2002).   The defendant argues that the text message sent by the
    victim fails to meet either requirement for admissibility.3    We
    disagree and conclude that the judge committed no error in
    admitting the victim's cellular telephone text message in
    evidence.
    While Massachusetts appellate courts have yet to approve
    admission of text messages or any other writing under the
    spontaneous utterance exception to the hearsay rule, this
    exception does not categorically exclude written statements from
    its scope.   We have acknowledged that a written statement may be
    considered a spontaneous utterance if it satisfies a heightened
    indicia of reliability.   See Commonwealth v. DiMonte, 
    427 Mass. 233
    , 237-240 (1998).   There we explained that "[b]ecause a
    writing is more suspect as a spontaneous exclamation than is an
    oral statement, the circumstances of the writing would have to
    include indicia of reliability even more persuasive than those
    required for an oral statement before we could conclude that the
    3
    The defendant also argues that the message was not
    sufficiently authenticated as being sent by the victim. In the
    circumstances of this case, where the defendant did not contest
    the authenticity of the text message during the trial, the
    authenticity requirement was satisfied by Evan's testimony and
    his cellular telephone records showing a message originating
    from the victim at 3:03 P.M.
    13
    writing qualified as a spontaneous exclamation."   Id. at 239.
    The heightened indicia of reliability requirement, however, does
    not impose an additional test in the spontaneous utterance
    analysis.   Rather, it is intended only to ensure that a writing,
    which generally is a product of reflection, meets the
    spontaneity requirement.   Thus, although we examine a writing
    more closely on the element of spontaneity, the analysis is the
    same as for an oral statement.
    The first requirement, that there be an exciting event
    giving rise to the exception, is clearly satisfied by the
    statement itself, the 911 telephone call, and the victim's
    condition approximately ten minutes later.4   See Commonwealth v.
    Nunes, 
    430 Mass. 1
    , 4 (1999), citing Commonwealth v. Whelton,
    
    428 Mass. 24
    , 27 (1998) ("The statement itself may be taken as
    proof of the exciting event").   The victim stated in her text
    message, "He is threatening to kill me I am scared he said if I
    pick up the phone he will kill me."   Although the record
    4
    The defendant acknowledges that the content of the text
    message statement itself satisfies this requirement, but
    asserts, without citation to any cases, that the confrontation
    clause of the Sixth Amendment to the United States Constitution
    requires that there be additional evidence of the event besides
    the statement. Regardless of whether the defendant's argument
    has any basis in law, the occurrence of an exciting event having
    very recently occurred was confirmed by the condition of the
    victim and apartment when the police arrived minutes later. See
    Commonwealth v. Whelton, 
    428 Mass. 24
    , 26-27 (1998).
    14
    contains no further information about the events occurring at
    that moment, it is established that six minutes later the victim
    frantically telephoned 911 to report that her husband was
    stabbing her and, only a few minutes after that, she was found
    barely breathing and lying in a pool of blood.
    In determining the second element of spontaneity, we
    consider the circumstances of the statement, including the
    temporal relation between the event and the statement, and the
    tone and manner of the declarant.    Commonwealth v. Simon, 
    456 Mass. 280
    , 296, cert. denied, 
    562 U.S. 874
     (2010); Santiago, 437
    Mass. at 623, 625; DiMonte, 427 Mass. at 239.    Because the
    statement at issue here is a writing, we also consider whether
    and to what extent the requisite spontaneity is compromised by
    this method of communication.
    Here, the circumstances of the statement, although in the
    form of a cellular telephone text message, are entirely
    consistent with spontaneity.    As described above, the victim
    telephoned 911 to report that the defendant was stabbing her six
    minutes after the text message to her son reporting that the
    defendant was "threatening to kill" her.    This sequence of
    events closely resembles a scenario mentioned in DiMonte, 427
    Mass. at 239, where we observed that a writing may be admissible
    "when a victim is held hostage and is unable to communicate in
    15
    any way other than writing or when a person's vocalization is
    impaired" (footnote omitted).
    The circumstances under which the text message was sent
    adequately compensate for the limitations inherent in a writing
    and meet the spontaneity test.   Cellular telephone text messages
    are a unique form of written communications in that they allow
    for instant communication in much the same way as oral
    communications.   The cellular technology that allows for the
    sending and receiving of a text message instantly, often as a
    substitute for oral expression, diminishes the concern about
    spontaneity that might arise with other more deliberative modes
    of written communication.   Further, the growth of cellular
    telephones has made text messaging and other types of written
    electronic statements ubiquitous forms of rapid communication.5
    For a person proficient in the use of the cellular telephone
    technology, sending a text message may involve no more effort
    5
    In Lorraine v. Markel Am. Ins. Co., 
    241 F.R.D. 534
     (D. Md.
    2007), a judge of the United States District Court for the
    District of Maryland reviewed case law interpreting evidentiary
    rules for application to electronic communications. The judge
    concluded that electronically stored communications may be
    admissible under the Federal rule governing spontaneous
    utterances, Fed. R. Evid. § 803(2), noting the "prevalence of
    electronic communication devices, and the fact that many are
    portable and small, means that people always seem to have their
    laptops, [personal digital assistants], and [cellular
    telephones] with them, and available for use to send [electronic
    mail messages] or text messages describing events as they are
    happening." Id. at 569.
    16
    than verbalizing a thought, feeling, or emotion in response to
    an event.   A cellular telephone user may choose between verbal
    and written communication without sacrificing immediacy in the
    communication of the message.6   This opportunity for instant
    communication by way of cellular telephone technology elevates
    text messages, at least on the spontaneity scale, beyond the
    level of an ordinary writing.    See DiMonte, 427 Mass. at 239.
    Thus, we conclude that the spontaneity requirement is not
    undermined in this case by the fact that the statement is a
    writing in the form of a cellular telephone text message.
    Although the temporal relation requires no definite and
    fixed limit of time for spontaneity, "the further the statement
    from the event, the more difficult it becomes to determine
    whether the statement is the result of reflection, influenced by
    other factors."   DiMonte, 427 Mass. at 239, citing Commonwealth
    v. McLaughlin, 
    364 Mass. 211
    , 223 (1973).   The rationale behind
    the temporal relation is that statements made before the
    6
    More text messages are sent and received by cellular
    telephone users than voice minutes are expended. According to a
    Nielsen study conducted in 2012, ninety-four per cent of United
    States consumers age sixteen years and older use a cellular
    telephone, and the average United States cellular contract user
    sent or received 764.2 text messages and used 644.1 voice
    minutes per month. See The Nielsen Company, The Mobile
    Consumer: A Global Snapshot 7, 19 (Feb. 2013), available at
    http://www.nielsen.com/content/dam/corporate/uk/en/documents/Mob

    Nielsen Consumer Value Metrics (2012).

    declarant has time to "contrive and misrepresent" would be
    admitted, while others made after the "exciting influence [has
    lost] its sway" would be inadmissible.    McLaughlin, 
    supra,
    quoting 6 J. Wigmore, Evidence § 1750 (3d ed. 1940).    In this
    case, the statement occurred within a reasonable temporal
    proximity to the exciting event because the victim's subsequent
    911 telephone call and death shortly thereafter demonstrate that
    the event was in progress when she sent the text message.
    Likewise, the tone and manner of the declarant, as
    evidenced by the writing itself, supports a determination that
    this statement was spontaneous, and thus reliable.     See Simon,
    
    456 Mass. at 296
    .    The message was one sentence without any
    punctuation.   The message related only to the circumstances of
    the threat to the victim's safety and her reaction (fear) to
    that threat.   In contrast, the facsimile transmission in
    DiMonte, 427 Mass. at 234 n.4, which we said was not
    spontaneous, was much longer and related to arrangements for an
    upcoming concert at which the victim was to sing in addition to
    the prior assault.
    For all the reasons explained above, we are persuaded that
    the circumstances of the statement, the tone and manner of the
    statement and its timing, establish the second requirement of
    the spontaneous utterance exception to the hearsay rule.     The
    judge's decision to admit the statement was sound.
    18
    Last, statements admissible as spontaneous utterances must
    also satisfy the confrontation clause of the Sixth Amendment to
    the United States Constitution.    See Irene, 462 Mass. at 609.
    "The confrontation clause bars the admission of testimonial out-
    of-court statements by a witness who does not appear at trial
    unless the witness is unavailable to testify and the defendant
    had an earlier opportunity for cross-examination."    Id. at 617,
    citing Crawford v. Washington, 
    541 U.S. 36
    , 53-54 (2004).
    "Whether a particular statement is 'testimonial' lies at the
    core of this analysis."    Irene, supra, citing Davis v.
    Washington, 
    547 U.S. 813
    , 823-824 (2006).    The defendant asserts
    that the statement was testimonial in fact because the victim
    did not ask for help or describe an earlier event and that she
    instead intended to establish the identity of her potential
    perpetrator.    We disagree with the defendant's characterization
    of the statement.
    "A statement is testimonial in fact if 'a reasonable person
    in the declarant's position would anticipate the statement's
    being used against the accused in investigating and prosecuting
    the crime.'"7   Simon, 
    456 Mass. at 297
    , quoting Commonwealth v.
    7
    Whether a statement is testimonial in fact is the second
    step in determining whether a statement was testimonial.
    Commonwealth v. Simon, 
    456 Mass. 280
    , 297, cert. denied, 
    562 U.S. 874
     (2010). The statement was not testimonial per se,
    which is the subject of the inquiry in the first step, because

    Gonsalves, 
    445 Mass. 1
    , 12-13 (2005), cert. denied, 
    548 U.S. 926
    (2006). Although the victim did not explicitly ask for help, she
    wrote, "He is threatening to kill me I am scared he said if I
    pick up the phone he will kill me."   Further, she did not name
    the defendant, a fact likely to be communicated by a declarant
    attempting to establish her perpetrator's identity.   Rather, the
    statement is more properly characterized as one made in the
    context of an ongoing emergency for which the victim sought
    assistance.   Thus, the judge did not err in admitting the text
    message.
    ii.    Availability of suppressed statement for impeachment.
    The defendant argues that the judge erred in ruling that the
    Commonwealth would be permitted to rebut evidence of the
    defendant's mental capacity insofar as it rested on the claim
    that he was noncommunicative during booking and during his
    receipt of Miranda and telephone rights.   Although the judge
    explicitly ordered that the content of the statements would not
    be admitted, he ruled that the Commonwealth would be allowed to
    ask certain questions, such as, "Were there other questions
    asked . . . [h]ow many other questions were asked . . . what was
    his manner and demeanor in answering those questions and what
    were the general areas of conversation."   The defendant argues
    the statement was not made in a "formal or solemnized form" or
    "in response to law enforcement interrogation." 
    Id.
    20
    that this ruling was error for two reasons:    (1) the statements
    were involuntary and thus inadmissible for any reason; and (2)
    even if the statements were allowed to impeach the defendant's
    testimony, they could not be used to impeach his experts'
    testimony.
    Both of these arguments are unavailing.    The trial judge,
    after reviewing the transcript from the hearing on the motion to
    suppress and the video recording of the interrogation, concluded
    that the defendant's statements were voluntary because the
    defendant did not appear to be under the influence of drugs or
    alcohol, reported that he physically felt good, was tuned into
    subtleties, and responded to the police officer directly on the
    issues.8   The judge's conclusion is well supported by the record.
    See Commonwealth v. LeBlanc, 
    433 Mass. 549
    , 554 (2001).
    Accordingly, the rule cited by the defendant, that "any criminal
    trial use against a defendant of his involuntary statement is a
    denial of due process of law," is not applicable here (emphasis
    in original).   Commonwealth v. Durand, 
    457 Mass. 574
    , 591-592
    (2010), quoting Mincey v. Arizona, 
    437 U.S. 385
    , 398 (1978).
    The defendant's argument fails for the additional reason
    that the judge precluded the admission of the content of the
    8
    The motion judge, suppressing the statements on other
    grounds, did not decide the issue of voluntariness.
    21
    statements.   The judge ruled that only evidence of the
    defendant's ability to communicate would be admitted and only
    for the purpose of impeaching the defendant's claim that he was
    noncommunicative in the aftermath of the killing.   Evidence of
    the defendant's ability to answer questions, offered only to
    rebut evidence of the defendant's noncommunicability, is not
    barred by the Fifth or Fourteenth Amendment to the United States
    Constitution, or by art. 12.9
    The defendant next argues that this ability to communicate,
    as established by the existence of (the subsequently suppressed)
    statements to the police, was not admissible to impeach his
    expert witnesses even if such statements would have been
    admissible against him.   The defendant's argument stems from the
    limitations on the impeachment exception to the exclusionary
    rule as set forth in James v. Illinois, 
    493 U.S. 307
    , 320
    (1990).   The exclusionary rule bars the prosecution's use of
    statements, even if voluntary, that were obtained in violation
    of Miranda v. Arizona, 
    384 U.S. 436
    , 444 (1966), unless an
    exception applies.   James, 
    supra at 312
    , citing Harris v. New
    York, 
    401 U.S. 222
    , 225 (1971), and Oregon v. Hass, 
    420 U.S. 9
    The defendant's silence in response to Miranda warnings
    and booking questions, sought at trial to demonstrate mental
    impairment, was considered by the motion judge as evidence that
    the defendant invoked his right to remain silent and was
    accordingly used to support suppression.
    22
    714, 722 (1975).   Under the impeachment exception, "prosecutors
    [may] introduce illegally[10] obtained evidence for the limited
    purpose of impeaching the credibility of the defendant's own
    testimony."   James, supra at 312.   In James, the United States
    Supreme Court declined to extend the impeachment exception to
    allow impeachment of "all defense witnesses" because doing so
    "would not further the truth-seeking value with equal force but
    would appreciably undermine the deterrent effect of the
    exclusionary rule."   Id. at 320.    We have yet to interpret the
    meaning of "all defense witnesses," and we decline to do so now.
    Suffice it to say, evidence that the defendant answered a number
    of questions, without relating the content of the statements,
    that is offered for the purpose of showing communicability is
    not an impermissible use of illegally obtained statements and,
    therefore, does not offend the rule in James.
    iii.   Exclusion of expert witness testimony.    The defendant
    argues that the judge violated his right to present a defense
    and call witnesses under the Sixth Amendment and under art. 12
    by excluding the testimony of Dr. Stuart, whose testimony would
    review the effects of combining Celexa and alcohol and was
    10
    The statements suppressed in James v. Illinois, 
    493 U.S. 307
    , 313 (1990), were obtained in violation of the Fourth
    Amendment to the United States Constitution, not the Fifth
    Amendment to the United States Constitution as applicable in
    this case.
    23
    proffered to show that the defendant's conduct the night before
    the stabbing was a legitimate suicide attempt.   The judge
    excluded the testimony as cumulative, of limited relevancy, and
    unduly prejudicial, and because it could confuse the jury as to
    the relevant time frame in which to consider the defendant's
    mental state.   "[A] trial judge has the discretion to control
    the scope of the examination of witnesses . . . and can exclude
    witnesses whose testimony is cumulative, repetitive, or
    confusing."   Commonwealth v. Boyarsky, 
    452 Mass. 700
    , 711
    (2008), quoting Commonwealth v. Carroll, 
    439 Mass. 547
    , 552-553
    (2003).   "In addition, questions of relevancy 'are entrusted to
    the trial judge's discretion and will not be disturbed except
    for palpable error.'"   Commonwealth v. Wilson, 
    427 Mass. 336
    ,
    349 (1998), quoting Commonwealth v. Azar, 
    32 Mass. App. Ct. 290
    ,
    300 (1992).
    Although Dr. Stuart was to be the only expert testifying
    about the effects of Celexa and alcohol in combination, there
    was no evidence about the quantity of alcohol or drugs ingested
    at or near the time of the stabbing.11   While the expert intended
    11
    A defense expert witness testified that the defendant
    told him he consumed an excessive amount of alcohol and took
    pills on the evening before the stabbing, but these statements
    were not admitted for their truth. The jury also heard evidence
    that a bottle of rum two-thirds full and several prescription
    bottles of pills were located in the apartment after the
    stabbing.
    24
    to testify about the drug and alcohol combination to demonstrate
    that the defendant actually attempted suicide and not to show
    that the combination directly affected his state of mind the day
    of the stabbing, another expert had already testified that the
    defendant's actions were a suicide attempt.    The judge did not
    abuse his discretion in excluding Dr. Stuart's testimony.
    b.   Diminished capacity instruction.    The defendant argues
    that the judge committed reversible error by failing to instruct
    the jury that they could consider evidence of diminished
    capacity as it related to the defendant's ability to act with
    extreme atrocity or cruelty, as required by Commonwealth v.
    Rutkowski, 
    459 Mass. 794
    , 798 (2011).   Instead of giving the
    form of instruction approved in Commonwealth v. Gould, 
    380 Mass. 672
    , 686 n.16 (1980), as proposed by defense counsel, the judge
    gave the model jury instruction.   See Model Jury Instructions on
    Homicide 61-62 (1999).   The defendant's argument is unavailing
    because the judge instructed the jury in accordance with
    Rutkowski, supra.12   A judge is not required to give the precise
    12
    The relevant portion of the jury instructions are as
    follows:
    "More particularly, you may consider any credible evidence
    of the defendant’s mental impairment, and/or the use of
    drugs, in determining whether the defendant deliberately
    premeditated the killing of the deceased, that is whether
    the defendant thought before he acted, and whether the
    25
    instruction proposed by the defendant or as set forth in Gould.
    See Commonwealth v. Szlachta, 
    463 Mass. 37
    , 48-49 (2012), citing
    Commonwealth v. Sanders, 
    451 Mass. 290
    , 300 (2008), and
    Commonwealth v. Oliveira, 
    445 Mass. 837
    , 848 (2006).    There was
    no error.
    c.   Review under G. L. c. 278, § 33E.   We have reviewed the
    entire record and see no reason to exercise our power under
    G. L. c. 278, § 33E, to reduce the degree of guilt as requested
    by the defendant or to grant other relief.
    Judgment affirmed.
    defendant reached the decision to kill after reflection, at
    least for a short period of time, and whether the defendant
    acted in a cruel or atrocious manner, in causing the death
    of the deceased" (emphases added).
