    Indictment found and returned in the Superior Court
    Department on December 9, 2010.
    Following review by this court, 
    472 Mass. 665
    (2015), the
    case was tried before Renee P. Dupuis, J.
    Theodore F. Riordan (Deborah Bates Riordan also present)
    for Jonathan E. Niemic.
    Tara L. Johnston, Assistant District Attorney, for the
    Commonwealth.
    LENK, J.    In 2012, the defendant was convicted of murder in
    the first degree on a theory of extreme atrocity or cruelty in
    the stabbing death of Michael Correia on October 20, 2010.
    2
    Following the defendant's appeal from that conviction, we
    remanded the matter to the Superior Court, where the
    Commonwealth was given the option either of vacating the
    conviction and retrying the defendant on the murder indictment,
    or accepting a reduction of the verdict to manslaughter.      See
    Commonwealth v. Niemic, 
    472 Mass. 665
    , 667, 679 (2015) (Niemic
    I).   The Commonwealth elected to pursue a new trial.    At that
    trial, with a different judge presiding, another attorney for
    the defendant, and the same prosecutor, the jury convicted the
    defendant of murder in the first degree on theories of
    deliberate premeditation and extreme atrocity or cruelty.
    In this appeal, the defendant argues that a new trial is
    required because of four asserted errors at his second trial:       a
    violation of the protection against double jeopardy in pursuing
    the theory of deliberate premeditation, where the jury at the
    first trial had not checked the "guilty" box on the verdict slip
    for that theory; erroneously admitted testimony of a rebuttal
    witness, which later was treated as substantive evidence by the
    Commonwealth; improperly introduced testimony by a substitute
    medical examiner as to facts in the autopsy report; and a number
    of improprieties in the prosecutor's closing argument, including
    an issue repeated from the defendant's first trial.     The
    defendant also asks us to exercise our authority under G. L.
    c. 278, § 33E, to reduce the degree of guilt or to order a new
    3
    trial.
    We conclude that errors in the closing argument alone, both
    that are reprised from the first trial and those newly
    introduced, would require a new trial.   To the extent that this
    may be a close question, that determination is buttressed by
    other issues that emerged on our review pursuant to G. L.
    c. 278, § 33E.   Accordingly, the defendant's conviction of
    murder in the first degree shall be vacated and set aside.     On
    remand, the Commonwealth shall once again be given the option
    either of accepting a reduction in the verdict to manslaughter,
    or of retrying the defendant.
    Should the Commonwealth again choose to pursue the latter
    path, we recognize the costs that a third trial would occasion,
    on the parties, the witnesses, the victim's family, and the
    court.   We are nonetheless constrained to conclude that a new
    trial is necessary unless the Commonwealth decides to accept a
    reduced verdict.   See Commonwealth v. Kater, 
    388 Mass. 519
    , 534
    (1983), S.C., 
    394 Mass. 531
    (1985), 
    409 Mass. 433
    (1991), 
    412 Mass. 800
    (1992), and 
    432 Mass. 404
    (2000).
    1.   Background.   We recite the facts as the jury could have
    found them, in the light most favorable to the Commonwealth,
    reserving certain details for later discussion.   The victim was
    stabbed five times; any one of the wounds could have been fatal.
    The defendant testified at trial that he had stabbed the victim;
    4
    the primary issue before the jury was whether he had done so in
    self-defense.    The theory of defense was that the older, taller,
    and heavier victim initiated a fist fight, and then pulled out a
    knife; the defendant managed to wrench the knife from the victim
    and swung wildly to fend off the victim.
    a.    Facts.   In the summer of 2010, the defendant was
    twenty-two years old and living in a halfway house in New
    Bedford for individuals who were recovering from alcohol and
    drug abuse.     He was dating Lisa Weaver, who lived at a different
    sober house in New Bedford.    During his time at the halfway
    house, the defendant befriended his roommates, James Nason and
    Nathan Goodwin.     The defendant also introduced Nason to his
    friend Kari Wright, and the two began dating.
    In August of 2010, the defendant left town for
    approximately two months.     When he returned, he moved in with
    his grandmother in New Bedford.     While he was away, the
    defendant wrote Weaver two love letters describing how "perfect"
    she was, and how he missed her and imagined them being together.
    At the same time, however, Weaver and the victim1 appeared to
    have begun a romantic relationship; they were seen in public on
    a number of occasions flirting, holding hands, and kissing.
    The defendant returned to New Bedford in October 2010.        A
    1   The victim was then thirty-four years old.
    5
    few days before the stabbing, Nason told the defendant about the
    relationship between Weaver and the victim.   Nason also said
    that the victim had referred to the defendant as a "punk," and
    had bragged that the victim "could take any girl away from [the
    defendant]."   The defendant told Nason that when they next met,
    he would punch the victim in the head.2   A friend of Weaver, who
    was her roommate at the sober house, testified that, at some
    point a few days prior to the stabbing, the defendant had
    appeared at an alcoholics anonymous (AA) meeting looking for the
    victim.
    On October 19, 2010, Weaver, Wright, and Nason picked up
    the defendant in a sport utility vehicle (SUV) belonging to
    Wright's mother.   Weaver and the defendant embraced when they
    saw each other, and sat together in the rear seat.    At some
    point, Wright heard the defendant angrily asking, with reference
    to an unknown topic, "Why didn't you tell me that?"   The group
    spent the day at Wright's parents' house, where the relationship
    between Weaver and the defendant seemed affectionate, as usual.
    The group left so that Weaver could get back to the sober house
    before her 11 P.M. curfew.   They planned to meet the following
    day to paint a property in Abington that belonged to Weaver's

    fighter, and for "a couple of" months had been working out at a
    gym, training on punching the heavy bag.
    6
    parents.
    On October 20, 2010, at approximately 3 P.M., the
    defendant, Weaver, Nason, and Wright arrived at the building in
    Abington, and painted until 6:30 P.M., when it got dark.     They
    left intending to return to New Bedford.   En route, Weaver
    realized that she did not have her house key.   She then
    remembered that some of her housemates would be attending an AA
    meeting at a soup kitchen at New Bedford, which regularly took
    place from 7 P.M. until 8:30 P.M. on Wednesdays, and decided
    that she could later enter the sober house with them.      The four
    thus headed to the soup kitchen.   On the way, the defendant
    asked Nason to stop at the side of the road because he had to
    urinate, but Wright would not allow this, as neither she nor
    Nason had a valid driver's license, and she did not want Nason
    to be caught at the side of the road if any police officers
    passed by.
    Between seventy and one hundred twenty people attended the
    meeting that evening.   The defendant, Weaver, Nason, and Wright
    reached the soup kitchen shortly before the usual break between
    7:30 and 7:45 P.M., when many people would go outside to smoke.
    Nason parked approximately 200 yards from the front door.
    Wright remained in the vehicle, while the others headed to the
    soup kitchen.   They encountered their former roommate Goodwin
    standing outside.   Nason and the defendant chatted with Goodwin
    7
    for approximately five minutes, and then went inside to use the
    restroom.    Weaver also went into the building to use the
    restroom, and then joined the crowd outside.
    When the defendant and Nason returned to the vehicle, the
    break had begun and numerous meeting participants were heading
    outside.    Nason pointed out to the defendant that the victim was
    at the meeting, and then returned to the SUV.
    At that point, approximately eighty people were outside, in
    a small, crowded area.     The victim and Goodwin were standing
    approximately fifteen feet from the entrance to the soup
    kitchen, looking at something on a cellular telephone.       The
    defendant went over to talk to Weaver, who was standing on the
    corner near a crosswalk approximately thirty feet away from the
    victim.     Nason moved the SUV closer to the crosswalk, and stayed
    inside with the vehicle idling.     The defendant gestured to the
    victim, indicating that he wanted to talk.     The victim
    apparently held up a finger, in a "just a minute" gesture.         The
    defendant gave Weaver "a quick goodbye kiss."     She seemed
    "concerned" and appeared to try to "pull[] him back" from
    talking to the victim, and then the defendant and Weaver kissed
    again.3    At some point, the defendant pulled the hood of his
    3 The evidence as to the extent of physical contact between
    the defendant and Weaver, like much other testimony, differed
    widely, ranging from descriptions of talking only, to a brief
    goodbye kiss or a peck on the cheek, to more protracted kissing

    sweatshirt up.   He crossed the street and opened the rear
    passenger door of the SUV as though he were about to get in, but
    then left the door slightly ajar and walked over to the victim.4
    The defendant said, "I've been hearing some things.     I feel
    disrespected"; the victim asked what the defendant had heard.
    The defendant began punching the victim, aiming at his head,
    while the victim attempted to ward off the blows.5   The defendant
    tried to hold the victim in a headlock, but the victim broke
    free.    At some point, the victim lifted his arms up with his
    palms facing outward and said something to the effect of, "What?
    Are you going to use a knife?"6   The defendant lunged at the
    or hugging before and as the defendant was heading away, when
    Weaver grabbed him by the arm and pulled him back.
    4 Multiple witnesses testified for the Commonwealth and also
    during the defendant's case. Their descriptions of events
    surrounding the confrontation varied widely, even among
    witnesses for the Commonwealth. As with much of the other
    testimony about the confrontation, the testimony on this point
    was conflicting. Only two of the ten witnesses who described
    the events mentioned the defendant as going over to the SUV and
    then returning to the victim; none of the other witnesses
    testified that the defendant went to the SUV before he
    approached the victim. We present the testimony in the light
    most favorable to the Commonwealth.
    5 Wright noticed the altercation and got out of the SUV to
    break up the fight, but dropped her cellular telephone, and its
    battery fell out. By the time she had retrieved the battery and
    the telephone, the defendant was getting into the rear seat of
    the SUV, so Wright returned to the front seat.
    6 Both the defendant and the victim were known at times to
    have carried knives. The knife used in the stabbing had a black
    9
    victim four to five times.   The victim ran into the soup
    kitchen.   The defendant chased him into the building.   About
    twenty seconds later, the defendant ran out of the building and
    into the SUV; the vehicle then was driven away.7
    Bystanders carried the victim, who was saying that he had
    been stabbed and that someone should telephone 911, upstairs to
    the meeting hall and tried to render first aid.    His father was
    present.   Emergency medical technicians (EMTs) arrived within a
    few minutes.   The victim lost consciousness shortly thereafter.
    He was taken to a hospital by ambulance, where physicians
    attempted emergency surgery, but their efforts were unsuccessful
    and the victim was pronounced dead.   He had suffered five stab
    wounds, any one of which could have been fatal.    The two wounds
    on the left side of the chest had penetrated the heart, and a
    wound to the lower right side had perforated the liver.     The
    handle and a black blade, different from the knife the defendant
    had been known to carry, but both were "flick" knives.
    7 A number of witnesses testified that when the defendant
    initially confronted the victim, the victim threatened to stab
    the defendant or punched him in the head. The defendant
    testified that the victim threatened to stab him, and then
    quickly punched him on the side of his head, before reaching
    down into a pocket and pulling out a knife. The defendant
    wrenched the knife away, while the victim continued to attack
    the defendant. The defendant then started swinging wildly with
    the knife. Other witnesses said that there was a "fist fight"
    and they could not see who threw the first punch. After a
    flurry of punches, the victim eventually backed off, and the
    defendant ran to the SUV.
    10
    fourth and fifth wounds were to the back and the lateral part of
    the chest.     The victim was determined to have died within
    minutes of the stabbing.
    Meanwhile, the SUV, with Nason driving, headed toward the
    highway.   The defendant noticed that he had blood on his hands.
    Wright also noticed the blood and that the defendant had a small
    black folding knife in his lap.     The defendant told the others
    that he had been in a fight with the victim, he thought he had
    stabbed the victim, and he hoped the victim was "ok."     The
    defendant wanted to go to his grandmother's house, but Wright
    told Nason to drop him off at a grocery store in Fairhaven.     The
    defendant threw the knife out the window near the exit to the
    grocery store.
    When they reached the grocery store parking lot, the
    defendant cleaned the blood from his hands, with Wright's help,
    using one of her tank tops that had been in the back of the SUV.
    He discarded the tank top in the parking lot.     The others headed
    to Wright's parents' house, and the defendant waited at the
    grocery store until his grandmother picked him up.
    At 8:30 P.M., the defendant and his grandmother went to the
    home of John Voisine, the stepfather of a close friend of the
    defendant's.     The defendant borrowed some clothes from Voisine,
    11
    and remained in his apartment for approximately four hours.8       The
    defendant told Voisine he had been in a fight with the victim,
    that he was worried the victim might be dead, and that he had
    not intended to harm the victim, but had been acting in self-
    defense.   The defendant left sometime before midnight.
    That evening, police interviewed multiple witnesses.      They
    investigated the grocery store parking lot and discovered a
    discarded tank top covered with blood.     In a grassy area near
    the highway, police found a small black folding knife, covered
    with red-brown stains.     Around midnight, officers went to
    Voisine's apartment.     The defendant was not in the apartment,
    but officers eventually found him under a set of exterior stairs
    and arrested him.9
    Deoxyribonucleic acid from the blood on the knife handle,
    the blade, and the tank top contained a mixture of two profiles,
    with the "major profile" matching the defendant's; the minor
    profile on the tank top did not match the victim's.    The victim
    was a potential contributor to the minor profile on the knife
    handle and the blade.    The major profile of the stains on the
    8 The defendant later testified that he went to Voisine's
    house to use heroin, as that was the only thing he could think
    to do at the time.
    9 The defendant had one cut on his right hand and three on
    his left hand.
    12
    jeans that the defendant had been wearing, which were found at
    Voisine's house, matched the defendant's.
    The defendant called a number of witnesses, and also
    testified on his own behalf.   Several defense witnesses
    testified that when the defendant initially confronted the
    victim, the victim threatened to stab the defendant.10     The
    victim then punched the defendant on the side of his head,
    before reaching down and pulling out a knife.   The defendant
    wrenched the knife away, while the victim continued to attack.
    The defendant ultimately was able to run to the SUV.
    b.   Prior proceedings.   In December 2010, the defendant was
    indicted on a charge of murder in the first degree, G. L.
    c. 265, § 1.   After an eight-day trial in June 2012, a Superior
    Court jury found the defendant guilty of murder in the first
    degree on a theory of extreme atrocity or cruelty.     In September
    2015, after review of the defendant's direct appeal by this
    court, the matter was remanded to the Superior Court for entry
    of a reduced verdict of guilty of voluntary manslaughter or a
    new trial, as the Commonwealth preferred.   See Niemic 
    I, 472 Mass. at 667
    , 679.
    Prior to the defendant's second trial, he moved to preclude
    10Nason also testified that, a few months prior to this
    incident, the victim had threatened to "slice" the defendant if
    they saw each other again, and then later apologized to the
    defendant for making the threat.
    13
    the Commonwealth from pursuing the theory of deliberate
    premeditation, and later filed a motion to dismiss the charge of
    murder in the first degree on that theory.     Both motions were
    denied.    After a ten-day trial in September 2016, tried by the
    same prosecutor11 but with different defense counsel and before a
    different judge, a jury convicted the defendant of murder in the
    first degree on theories of deliberate premeditation and extreme
    atrocity or cruelty.
    2.    Discussion.   In this direct appeal, the defendant
    maintains that a new trial is required due to a violation of the
    protection against double jeopardy in pursuing the theory of
    deliberate premeditation after a purported acquittal.       He also
    claims error in the introduction of impeachment testimony of a
    rebuttal witness, which was later treated as substantive
    evidence by the prosecutor; impermissible testimony by a
    substitute medical examiner; and a number of improprieties in
    the prosecutor's closing argument.     We consider each issue in
    turn.
    a.    Double jeopardy.   At his first trial, the defendant was
    convicted of murder in the first degree on a theory of extreme
    atrocity or cruelty.     The jury checked the guilty box on the
    verdict slip for this theory, the foreperson presented it as the
    11   The second chairs, who did not argue, differed.
    14
    theory underlying the conviction, and the jurors all agreed that
    they found the defendant guilty under that theory.   See
    Niemic 
    I, 472 Mass. at 666
    .   On the verdict slip concerning
    murder on a theory of deliberate premeditation, the jury checked
    neither the "guilty" nor the "not guilty" box.   The foreperson
    also made no reference to the theory of deliberate premeditation
    when responding to the session clerk in announcing the verdict.
    At the second trial, the defendant was convicted on both
    theories.
    The defendant now contends that the jury found him not
    guilty of murder on a theory of deliberate premeditation at his
    first trial, based on their failure to check that box.
    Therefore, he claims, it was a violation of the double jeopardy
    clause of the Fifth Amendment to the United States Constitution
    to have retried him on that theory a second time.
    This court repeatedly has declined to accept a jury's
    failure to mark one of the theories of a charge as an acquittal
    on that theory.   See Commonwealth v. Carlino, 
    449 Mass. 71
    , 78-
    79 (2007), and cases cited; Commonwealth v. Nardone, 
    406 Mass. 123
    , 132-134 (1989); Commonwealth v. Preston, 
    393 Mass. 318
    ,
    320, 325 n.8 (1984).   Courts in other jurisdictions also have
    determined that retrial is not barred in such circumstances.
    See United States v. Ham, 
    58 F.3d 78
    , 84-86 (4th Cir.), cert.
    denied, 
    516 U.S. 986
    (1995); Beebe v. Nelson, 
    37 F. Supp. 2d 15
    1304, 1307-1308 (D. Kan. 1999); State v. Pexa, 
    574 N.W.2d 344
    ,
    347 (Iowa 1998).   We see no reason to disturb our well-
    established precedent in this case.
    The defendant argues further that because silence was
    interpreted as "no" with respect to the absence of a response to
    a question to the venire during empanelment (when no members of
    the venire raised their hands in response to some of the judge's
    questions), silence likewise must be interpreted as "no" in the
    context of unmarked boxes on the verdict slip.   We do not agree.
    There is no indication that the jury were aware that
    silence on a particular theory would be deemed an acquittal.
    Rather, they were told that they had to be unanimous in deciding
    whether the defendant was guilty or not guilty, and that the
    foreperson was "simply to put an X or a check mark next to the
    appropriate verdict and then sign it certifying that it's
    unanimous."   They were instructed further that, if they found
    the defendant guilty, they had to be unanimous as to which of
    the "two types of murder in the first degree [they found]. . . .
    [I]t can be one, or the other, or both."
    We cannot ascertain by the jury's silence on the theory of
    deliberate premeditation whether they actually reached a
    unanimous decision to acquit the defendant on that theory.     By
    contrast, we do know definitively that the first jury were
    unanimous in their conviction on a theory of extreme atrocity or
    16
    cruelty at the first trial.     Thus, retrial on the theory of
    deliberate premeditation was not error.
    b.   Rebuttal testimony.   Toward the end of trial, after the
    defendant had rested his case, the Commonwealth recalled Wright
    as a rebuttal witness.12   Over the defendant's objection, she
    testified that, as the defendant approached the victim, Nason
    said "[the defendant] wants to sucker Mikey [(the victim)].
    Sucker punch Mikey."   While the testimony was admitted for the
    limited purpose of impeaching Nason's credibility, neither party
    requested a limiting instruction.13
    12At the beginning of trial, the judge conducted a hearing
    on the defendant's motion in limine to introduce certain
    statements made in the SUV by the defendant after the stabbing.
    The judge then ordered the statements excluded on the
    representation of the prosecutor that the Commonwealth would not
    be seeking to introduce any of the other statements made by the
    occupants of the vehicle. On direct examination by the
    defendant, Nason testified that, on the evening of the stabbing,
    he was not expecting a physical confrontation between the
    defendant and the victim when the defendant headed toward the
    victim. On cross-examination, Nason testified that, several
    days earlier, the defendant had told Nason that the next time he
    saw the victim, he was going to "punch [the victim] in the
    head." Nason added that he had not believed that the defendant
    intended to act on the statement, which Nason viewed as
    something "everybody says." On further questioning, Nason
    testified that he did not remember having told Wright, while
    they were in the SUV, that the defendant planned to "sucker
    punch" the victim. After the defense rested, the judge then
    allowed the prosecutor to recall Wright to impeach Nason's
    testimony with her own recollection of his prior inconsistent
    statement.
    13Before her final charge, on her own initiative, the judge
    instructed the jury on the limited purpose for which they could
    consider Wright's rebuttal testimony that Nason told her the
    17
    The defendant now challenges the admission of Wright's
    testimony as reversible error on the ground that it was
    irrelevant and impermissible hearsay.14   Because the statements
    concerned the core issue at trial of the defendant's intent in
    approaching the victim -- in the defendant's words, "the most
    important issue in the case" -- the defendant maintains that
    their improper admission constituted prejudicial error.    We do
    not agree.
    There was no error in the introduction of Wright's rebuttal
    testimony that the defendant wanted to "sucker punch" the victim
    in order to impeach Nason's testimony.    The testimony had the
    potential to undermine Nason's credibility in the eyes of the
    jury, given Nason's testimony on cross-examination that he did
    not recall telling Wright the defendant had wanted to sucker
    punch the victim, and, indeed, believed that the defendant
    defendant intended to "sucker punch" the victim.   See part 2.d,
    infra.
    14Because the defendant objected at trial to the
    introduction of the rebuttal testimony, we review for
    prejudicial error. See Commonwealth v. Barbosa, 
    477 Mass. 658
    ,
    673 (2017), citing Commonwealth v. Canty, 
    466 Mass. 535
    , 545
    (2013) (reviewing for prejudicial error where objection was
    preserved). "An error is not prejudicial if it 'did not
    influence the jury, or had but very slight effect'; however, if
    we cannot find 'with fair assurance, after pondering all that
    happened without stripping the erroneous action from the whole,
    that the judgment was not substantially swayed by the error,'
    then it is prejudicial."

    , 377 (1950).     See Mass. G. Evid.
    § 613(a)(2), (3) & note (2019).    "Although there is discretion
    involved in determining whether to admit or exclude evidence
    offered for impeachment, when the impeaching evidence is
    directly related to testimony on a central issue in the case,
    there is no discretion to exclude it."    Mass. G. Evid.

    The rebuttal testimony was particularly important here for
    two reasons.   First, as the defendant argues, it concerned the
    seminal issue in the case:   the defendant's intent at the time
    he approached the victim.    Secondly, the evidence of that intent
    rested in large part on the jury's view of the witnesses'
    credibility, in a case in which almost all the witnesses
    described the events in significantly different ways, many had
    15Under certain conditions, not present here, a prior
    inconsistent statement made under oath may be admissible not
    just to impeach a declarant's trial testimony, but also for its
    truth. See Mass. G. Evid. § 801(d)(1)(A) (2019).
    19
    known the victim, the defendant, or both, and many were
    vulnerable to impeachment.    Both Wright, the Commonwealth's
    primary witness,16 and Nason, who testified for the defense, had
    been friends of the defendant.   Both had been present in the SUV
    with the defendant driving to the soup kitchen, and driving away
    after the stabbing, thus leaving either of them open to possible
    impeachment.17
    Although there was no error in the introduction of the
    rebuttal testimony for impeachment purposes, the later use of
    the statement as substantive evidence in closing is another
    matter.   See part 2.d, infra.
    c.   Autopsy report.   The defendant challenges the
    introduction of information in the autopsy report that was
    introduced by a substitute medical examiner.   The Commonwealth
    filed a motion in limine to introduce the testimony of Dr. Henry
    16There was evidence from which the jury could have
    concluded that Wright's testimony was not unbiased and she had a
    reason to cooperate with the prosecution. The defendant used
    Wright's tank top, which she had handed to him, to clean blood
    from his hands, and she helped him to do so by pouring water on
    them. Wright testified that, within minutes after she and Nason
    returned to her parents' house from dropping the defendant at
    the grocery store, police arrived. She and Nason accompanied
    the officers to the police station, where she remained until
    3 or 4 A.M. At the station, police took photographs, swabbed
    her hands and took a sample of her deoxyribonucleic acid.
    17Moreover, although Wright testified at the second trial
    that she and Nason were at that point broken up, the two had
    remained in an "on and off" romantic relationship "for years"
    and had two children together.
    20
    Nields, a substitute medical examiner, as the original medical
    examiner, Dr. William Zane, was unavailable at the time of
    trial.   The defense objected to the use of a substitute due to a
    concern that the defendant would be unable to elicit testimony
    from Zane that the victim had had an injury to his lip, which
    defense counsel viewed as supporting the theory that the
    encounter began as a fist fight.
    The Commonwealth offered either to stipulate to Zane's
    prior testimony or to conduct a video-recorded deposition that
    could be played at trial, rather than to rely on Nields's
    testimony.   The defendant rejected both of these options.
    Before Nields testified, the judge reminded both parties of the
    limitations on permissible testimony when using a substitute
    medical examiner, and reminded defense counsel that he had a
    duty to object individually to each question he thought violated
    the limitations on the introduction of underlying facts from the
    autopsy report.
    Defense counsel did not object to the prosecutor's
    questioning of Nields, nor to the introduction of the answers
    elicited directly from the autopsy report.   Indeed, the evidence
    from the autopsy report was introduced after defense counsel
    stated explicitly, with respect to a question from the
    Commonwealth about an injury to the victim's mouth that was not
    clearly visible on the autopsy photographs, that he had no
    21
    objection to evidence from the autopsy report being introduced
    on that particular issue.   On appeal, however, the defendant
    challenges the introduction of two different sets of facts from
    the autopsy report, as well as the prosecutor's emphasis on the
    improperly admitted evidence in his closing argument.18    In
    particular, the defendant points to information on the height
    and weight of the victim and the depth and nature of the
    victim's wounds.
    Nields testified, in response to an unobjected-to question
    from the prosecutor specifically asking about the content of the
    autopsy report, that the autopsy report described the victim as
    being five feet, eight inches tall, and weighing approximately
    one hundred and seventy-five pounds.   This evidence touched upon
    an important component of the defense strategy:   the defendant
    argued that he had been intimidated by the victim because the
    victim was ten years older, and taller and heavier than the
    defendant, in addition to being known to be aggressive ("a
    bully").   The defendant contends, therefore, that Nields's
    testimony created a substantial likelihood of a miscarriage of
    18Defense counsel also did not object when the prosecutor
    relied heavily upon the information from the autopsy report in
    his closing. See part 2.d, infra.
    22
    justice because it undermined the defense argument that the
    defendant was smaller than the victim.19
    We need not address the extent to which a substitute
    medical examiner who did not perform the autopsy may testify to
    the facts contained in the underlying autopsy report.        Even if
    this evidence were improperly admitted, where it is cumulative
    of other, properly admitted evidence, there is no substantial
    likelihood of a miscarriage of justice.       See Commonwealth v.
    Reavis, 
    465 Mass. 875
    , 884 (2013); Commonwealth v. Rogers, 
    459 Mass. 249
    , 268, cert. denied, 
    565 U.S. 1080
    (2011).        Here, other
    properly admitted evidence about the victim's height and weight
    placed essentially the same information before the jury.         That
    evidence included testimony by Dr. Richard T. Miller, a surgeon
    who was called to the emergency room to perform an emergency
    thoracotomy on the victim;    20   one of the witnesses to the
    19There was testimony that the defendant was six feet tall
    and weighed two hundred pounds, but there also was testimony
    that the defendant was smaller and thinner than the victim,
    maybe five feet, eight inches tall.
    20   Miller testified,
    "I -- difficult to say. He was being resuscitated on a
    trauma stretcher on a gurney in the emergency room. I
    would say he -- my impression was he was an average-sized
    individual, under six feet tall, somewhere between one
    hundred and sixty and one hundred and eighty pounds.
    That's my best recollection."
    The prosecutor then asked Miller if he had been able to "refresh
    [his] memory" by reviewing the autopsy report. When Miller
    23
    stabbing who testified that he believed the defendant and the
    victim were "[a]bout the same height;" and a friend of the
    victim who testified that the victim was shorter and wider than
    his own six feet and one hundred and ninety-five pounds.
    The defendant also challenges the introduction of
    information from the autopsy report describing the victim's
    wounds and stating that the wounds were three to four inches
    deep, information which was not evident from the autopsy
    photographs that Nields properly had relied upon earlier in his
    testimony.   The information about the wounds was introduced by
    the prosecutor's unobjected-to specific questions as to the
    contents of the autopsy report.
    Generally, where a defendant relies on erroneously admitted
    facts contained in an autopsy report to challenge the
    Commonwealth's theory of guilt, there is no substantial
    likelihood of a miscarriage of justice by the prosecutor's
    reliance on facts from the same report.    See Commonwealth v.
    McGowen, 
    458 Mass. 461
    , 481-482 (2010).    See also Commonwealth
    v. Nardi, 
    452 Mass. 379
    , 395-396 (2009).    Such is the case here.
    In his closing, defense counsel relied upon the challenged
    responded that he had, the prosecutor asked if the contents of
    the report were consistent with Miller's memory and Miller
    responded that they were, thus again introducing, albeit
    cumulative of other assumedly improper testimony, the contents
    of the autopsy report.
    24
    testimony regarding the depth of the wounds.    He argued that the
    nature of the wounds, and their depth, showed that the defendant
    inflicted the fatal wounds to the heart while he swung wildly in
    self-defense, trying to push the victim off and that the victim
    died instantly.    Counsel focused as well on the injury to the
    victim's mouth, likely inflicted by a fist (termed "the busted
    lip" by the prosecutor), which counsel argued showed that the
    confrontation had begun with a fist fight.
    Moreover, Miller, the emergency room surgeon, testified
    that, ordinarily, a human heart lies between four and six inches
    below the surface of the chest, and that the victim's heart had
    been penetrated.    One of the witnesses who saw the encounter
    also testified that at first he saw someone wearing a "hoodie"
    punching with nothing in his hand, and later saw the man holding
    what looked like a "blade, four or five inches long."    This
    would have allowed the jury to infer, from properly admitted
    evidence, that the blade of the knife went four inches into the
    victim's body.21   See 
    Rogers, 459 Mass. at 268
    .
    d.   Prosecutor's closing argument.   The defendant contends
    that there were multiple improprieties in the prosecutor's
    21Defense counsel himself interrupted the prosecutor at one
    point to emphasize that, based on the autopsy report, the "three
    to four" inch depth of the wound was from the surface of the
    skin to the heart, not the depth of the cut in the heart itself.
    25
    closing argument, some reprising errors that contributed to the
    remand for a new trial in Niemic I.    In particular, the
    defendant points to the prosecutor's reliance on Wright's
    rebuttal testimony as though it were substantive evidence, and
    the reappearance, albeit in a more nuanced form, of the appeals
    to jury sympathy and suggestions that the defendant's testimony
    was not actual evidence,22 both of which we deemed impermissible
    in reviewing the prosecutor's closing in Niemic I.
    At his second trial, the defendant objected to the first
    two issues.   When the prosecutor finished his closing on
    retrial, defense counsel argued that no instruction could
    ameliorate the damage caused by the substantive use of the
    rebuttal testimony and the improper play to juror sympathy, and
    that a mistrial should be declared.
    We consider first whether the arguments were improper, and,
    if so, whether, in the context of the trial as a whole, the
    impropriety or combination of improprieties requires a new
    trial.    Given all the circumstances, we conclude that the
    22Notwithstanding that our remand in Commonwealth v.
    Niemic, 
    472 Mass. 665
    (2015) (Niemic I), was based in part on
    the prosecutor's unobjected-to suggestions in closing that the
    defendant's testimony was not evidence, at the second trial
    defense counsel again did not object when the prosecutor made a
    number of statements that were virtually identical to those
    sharply criticized at the first trial. Given the result we
    reach on the other issues, we need not address the extent to
    which these statements alone may have resulted in a substantial
    likelihood of a miscarriage of justice.
    26
    improprieties in the prosecutor's closing alone warrant a new
    trial.    That conclusion is further reinforced when other errors
    that emerged during our review under G. L. c. 278, § 33E, are
    considered in conjunction with the challenged errors.
    i.   Substantive use of rebuttal testimony.   At four points
    in his closing, the prosecutor referenced Wright's testimony
    concerning Nason's statement that the defendant was going to
    "sucker punch" the victim when he left the SUV.    Three of these
    were used substantively, and one was used properly for
    impeachment purposes.23   Three times, woven throughout his
    closing, the prosecutor relied on the statement to argue that
    the defendant clearly intended to assault the victim, not to
    talk to him and resolve any issues, when the defendant
    approached.24
    The prosecutor maintained further, as the judge commented,
    23The prosecutor's fourth reference to Wright's rebuttal
    testimony, made in the context of his vigorous efforts to
    discredit several witnesses who testified that the victim threw
    the first punch, was properly used for impeachment purposes.
    The prosecutor argued that Nason and the defendant had testified
    that the victim "land[ed] a punch on the defendant," and
    contrasted that with Wright's testimony that Nason told her the
    defendant was going to "sucker punch" the victim; the
    prosecutor asked, "Is she making that up? Is she not credible?
    What does that say to you about who is the aggressor?"
    24On appeal, the Commonwealth concedes that the substantive
    use of Wright's testimony in the prosecutor's closing was error,
    but states that this error did not result in a substantial
    likelihood of a miscarriage of justice.
    27
    "very effectively," that the defendant had gone to the soup
    kitchen with a "purposeful plan" to attack the victim, and that
    his own words proved the confrontation was planned, rather than
    an unexpected fight in which the defendant stabbed in self-
    defense.    Indeed, the prosecutor's use at closing of the
    statement as substantive evidence was so emphatic that, after
    the prosecutor's closing, the judge noted sua sponte that the
    statement went to the "seminal" issue at trial (the defendant's
    intent when he went over to the victim), that she thought
    Wright's testimony had been introduced only for rebuttal
    purposes, and that she was going to give a limiting instruction
    to that effect.    Immediately before her final charge, the judge
    instructed the jury accordingly.25
    Improper argument by a prosecutor can be harmless error
    where confined to collateral issues and accompanied by a
    25   The judge instructed:
    "Ms. Wright was called this morning in rebuttal, and she
    testified about a statement that she alleged Mr. Nason made
    to her about -- that he, Mr. Nason, told her that the
    defendant was going to sucker [the victim]. The only
    reason that that testimony was admitted, and we'll talk
    about this a little bit later on, was to impeach Mr.
    Nason's testimony. That's the only reason it was allowed
    in, and I'll talk to you about impeachment. You may not
    consider that evidence from Ms. Wright this morning for any
    other purpose than impeaching Mr. Nason's testimony. You
    may not specifically consider it or attribute it in any way
    to the defendant and his state of mind."

    curative instruction.    Commonwealth v. Shelley, 
    374 Mass. 466
    ,
    470 (1978), S.C., 
    381 Mass. 340
    (1980), and 
    411 Mass. 692
    (1992).    The prosecutor's repeated use of what had been admitted
    for a limited purpose as substantive evidence here, however,
    undermined the heart of the defense, "namely, the defendant's
    credibility as to who was the initial aggressor, who produced
    the knife, and whether the defendant acted in self-defense."26
    Niemic 
    I, 472 Mass. at 677
    .    The improper references to the
    testimony as substantive evidence during closing argument could
    not but have had an effect upon the jury.    See part 2.v, infra.
    Contrast Commonwealth v. Giguere, 
    420 Mass. 226
    , 234-235 (1995).
    ii.   Appeals to juror sympathy and emotion.   The defendant
    argues that in his closing the prosecutor improperly appealed to
    the jury's sympathies, thus replicating an error in Niemic I
    that contributed to the need for a new trial.    See Niemic 
    I, 472 Mass. at 675
    .   The Commonwealth concedes that, rather than
    steering a wide berth around this error on retrial, the
    prosecutor relied on virtually the same language on a number of
    occasions.   Notwithstanding this court's decision in Niemic 
    I, supra
    , the Commonwealth argues that the language was not an
    26We are cognizant that here, as with other testimony that
    had been excluded or was inadmissible, it was defense counsel's
    own questions that resulted in the introduction of the
    previously excluded statement, with apparently significant
    harmful effect on his client.
    29
    improper appeal to sympathy, but, rather, was "entirely
    appropriate."    Alternatively, the Commonwealth maintains that,
    in "context," no reasonable juror would have drawn the inference
    from the challenged statements that the prosecutor was appealing
    to sympathy or saying that the defendant's testimony was
    inherently incredible.    The Commonwealth also suggests that the
    asserted improprieties were relatively minor in scope in
    comparison to the percentage of the closing that they
    encompassed in Niemic I; in the Commonwealth's view, "only four"
    remarks by the prosecutor are at issue.     While certain specific
    statements were not reiterated in the prosecutor's second
    closing,27 the emphasis on the impermissible arguments was not
    any less "hard driving and sustained" on "critical aspect[s] of
    the case."28    
    Id. at 677.
      The impact of the closing on the jury
    27Many of the detailed statements about the efforts to
    render aid to the victim, by attendees at the meeting, by the
    EMTs, and at the hospital, that this court had criticized in
    Niemic I, were instead made in the prosecutor's opening
    statement at the retrial, and mentioned more briefly in his
    closing argument.
    28As he had in Niemic I, "[t]oward the end of his argument
    the prosecutor focused on the Cunneen factors that must be
    considered on the question of extreme atrocity or cruelty."
    Niemic 
    I, 472 Mass. at 675
    . "This part of the prosecutor's
    closing was very powerful, and proper. The prosecutor should
    have stopped there." 
    Id. Thereafter, "[t]he
    improper comments
    at the end of the closing comprised a structural segment,
    indeed, the denouement of the prosecutor's closing. This
    section of his argument was integrated into his argument of the
    Cunneen factors, particularly the defendant's indifference
    to the victim's suffering." 
    Id. at 676.
                                                                      30
    should be judged not by the number of transcript pages it
    occupies, but by the import of its use.29   Moreover, in many
    instances the language used was perilously close to that which
    had been found inappropriate in Niemic I.
    At the defendant's second trial, the prosecutor began and
    ended his closing with the same attempt to tug at the jury's
    heart strings.   Indeed, he framed his argument with equally
    improper plays to juror sympathy in virtually the same language
    that he had used at the first trial, including the victim's last
    words to his father -- "Dad, don't let me die, don't let me
    die," with which the prosecutor once again ended his closing --
    which had been a focus of the court's discussion of the
    29In any event, the numbers favor the defendant. The
    prosecutor's sympathy argument in total was longer at the second
    trial than at the first. In Niemic I, the prosecutor's closing
    argument in full required thirty-one pages of transcript; of
    these, approximately the last six pages were devoted to the
    improper argument. At the second trial, the prosecutor's
    closing argument covered approximately thirty-nine pages of
    trial transcript, approximately twenty-one percent longer than
    at the first trial. While much of the last ten pages of the
    second closing was devoted to improper argument, the improper
    argument began in the first paragraph of the first page, and was
    woven throughout. Furthermore, the prosecutor's opening
    statement at the new trial also began with reference to the same
    inflammatory statement by the victim that had been a focus of
    the improprieties in the closing at the Niemic I trial.
    Finally, three pages of the prosecutor's opening statement
    contained the reported efforts of meeting attendees, EMTs, and
    emergency room personnel to save the victim for which the
    prosecutor had been admonished in Niemic I. See note 
    27, supra
    .
    31
    improprieties in Niemic 
    I, 472 Mass. at 675
    -676.    The prosecutor
    then proceeded in the same vein as at the first trial,
    frequently using much the same language.    Structuring his
    argument with the jury's focus on the victim's words, he ended
    with the same pleading statement by the victim.    For example,
    First Trial                      Second Trial
    "And they saw him struggling     "Ladies and gentlemen, on
    and bleeding in front of his     October 20, 2010, there was a
    own father." See Niemic I, 472   brutal, senseless murder in the
    Mass. at 675.                    city of New Bedford. The
    brutality you've already heard
    about. A young man unarmed, set
    upon by the defendant, hands up,
    defenseless, stabbed multiple
    times over and over. Ends up
    bleeding out, dying, begging for
    his life in front of his father"
    (emphasis added).
    "What does that say about what
    he intended? Some punching,
    then the knife comes out.
    Stabbing. And then he is
    finishing the job right up to
    the point where he chases him
    down, stabs him in the side and
    in the back, and then leaves him
    to die, bleeding out, right at
    the -- in front of all these
    people, including his own father
    who -- give whatever
    consideration you want to the
    stipulation. It's hard to
    imagine how or what a father
    might say or understand in the
    course of watching his son bleed
    out in front of him, saying,
    'Dad, don't let me die. Don't
    let me die.'" (Emphases added.)
    "begging for his life"
    This is all the more surprising in that, shortly before
    32
    closing arguments, the parties informed the judge that they had
    entered into a stipulation concerning a statement by the
    victim's father about the victim's last words to him, a focus of
    our discussion in Niemic I.30   Defense counsel read the
    stipulation to the jury immediately prior to the closings.
    Rather than referencing the language in the agreed-upon
    stipulation, the prosecutor instead chose to attack the very
    idea of the stipulation to which he had agreed, arguing, as
    noted, "give whatever consideration you want to the stipulation.
    It's hard to imagine how or what a father might say or
    understand in the course of watching his son bleed out in front
    of him . . . ."
    As before, the prosecutor pointed out all the other people
    who happened to be present "at the wrong spot at the wrong
    time."    He also said that they had seen the victim "bleeding
    out," "begging for his life" "in front of all these people,
    including his own father," "at the start," "at the middle,"
    "and, unfortunately, the bitter end."    Foreshadowed by the
    prosecutor's opening,31 this language mirrored the prosecutor's
    30The stipulation was that the father stated, "My son comes
    running in. He said, 'Dad, I was just fighting with a guy.'"
    31The prosecutor's opening statement detailed the efforts
    of bystanders, EMTs, and emergency room doctors to save the
    victim, another "highly improper, emotionally charged
    discussion" that had featured in the court's admonition in

    improper statements in Niemic 
    I, 472 Mass. at 675
    , that the
    "civilian witnesses" were "at the wrong time at the wrong
    place."    As the court emphasized in Niemic I, "[t]he emotional
    impact on witnesses of the victim's death was not a proper
    matter for consideration by the jury."    
    Id. Notwithstanding this
    court's prior admonitions, after
    defense counsel objected at the end of the closing, the
    prosecutor told the judge:
    "The one thing I would say, Your Honor, just about dying in
    front of his father. One, begging for his life, that's in
    evidence; two, in front of his father, that was in
    evidence; and three, I do believe, and I think I maybe said
    this to you or I've said it, dying in front of your father
    to me is more conscious suffering than dying out in the
    woods alone. I mean, I would feel worse if I'm dying in
    front of my father. And so it goes to the issue of
    conscious suffering of the victim."
    Pointing, however, to this court's comments about playing to
    juror sympathy and emotion in Niemic I, the judge, just prior to
    her final charge, instructed the jury that sympathy, and
    specifically sympathy for the father, should play no role in the
    jury's deliberations.32
    32   The judge instructed:
    "[T]o the extent that in the closing argument [the
    prosecutor] talked about [the victim] begging for his life
    in front of his father and that the defendant left him to
    die in front of his father, you may not decide this case in
    any way, shape or form based upon sympathy. It's not to
    take any place in your deliberations. And if you
    interpret -- if you interpret that argument by [the
    34
    In Niemic 
    I, 472 Mass. at 675
    , we concluded that the
    prosecutor's "highly improper, emotionally charged discussion
    covering three pages of transcript" that attempted to inflame
    the jury's emotions was a significant factor in the need for a
    new trial.   Prosecutorial "appeals to sympathy . . . obscure the
    clarity with which the jury would look at the evidence and
    encourage the jury to find guilt even if the evidence does not
    reach the level of proof beyond a reasonable doubt."

    In addition to the defendant's claims concerning the
    prosecutor's closing argument, our review under G. L. c. 278,
    § 33E,33 reveals two other types of improprieties, namely that
    prosecutor] that he's -- as appealing to your sympathy, you
    are to disregard because that's not a proper purpose. It
    may be considered on other issues, but appealing to
    sympathy is not a proper purpose."
    See part 2.v, infra.
    33"General Laws c. 278, § 33E, directs us to review the
    case of a defendant convicted of murder in the first degree by
    considering the 'whole case,' and not merely questions that have
    been properly preserved for appellate review." Commonwealth v.
    Colleran, 
    452 Mass. 417
    , 430-431 (2008), quoting Commonwealth v.
    Hall, 
    369 Mass. 715
    , 736 (1976). "The statute states: 'Upon
    such consideration the court may, if satisfied that the verdict
    was against the law or the weight of the evidence, or because of
    newly discovered evidence, or for any other reason that justice
    may require (a) order a new trial or (b) direct the entry of a
    35
    the prosecutor used facts not in evidence or misstated facts and
    improperly stated his own opinion on multiple occasions.     We
    discuss each in turn.
    iii.     Facts not in evidence and misstatements of fact.      On
    more than ten occasions, the prosecutor argued facts not in
    evidence, often on issues central to the case, or asked the jury
    to draw inferences the evidence did not support.     We focus on
    only a few of the more significant misstatements:     (A) that the
    defendant had said a few months previously that he planned to
    slice up the victim at an AA meeting; (B) that the defendant had
    attempted deliberately to provoke the victim by overt romantic
    gestures with Weaver in front of the victim; and (C) that the
    victim had gone to the meeting that night to avoid the
    defendant.
    A.     "Slice" up the victim.   In one particularly glaring
    misstatement, the prosecutor argued that, several months before
    the stabbing, the defendant had told the victim he planned to
    "slice [the victim] up when [he saw him] at an AA meeting."
    There was no testimony that the defendant made such a statement.
    To the contrary, Nason testified that, a few months before the
    stabbing, the victim had said he would "slice" the defendant
    when they next met.     The defendant testified similarly.   Even if
    verdict of a lesser degree of guilt . . .'" (emphasis omitted).
    Colleran, supra at 431, quoting G. L. c. 278, § 33E.
    36
    meant sarcastically, the prosecutor was not free to attribute
    this testimony to the defendant. See Commonwealth v. Young, 
    461 Mass. 198
    , 206 (2012).
    B.     The kiss.     To emphasize the defendant's premeditation,
    and the inference that the defendant's interaction with Weaver
    was designed to upset or annoy the victim, the prosecutor argued
    repeatedly that the defendant had intentionally hugged and
    kissed Weaver multiple times, in order to provoke him.       "[The
    defendant] takes a position with [Weaver], and that's when all
    the hugging and the kissing, like right in front of [the
    victim].    Does that sound like he's trying to get a reaction:
    This is my girl.       There was a lot of hugging and kissing that
    was described."    The prosecutor sprinkled multiple references to
    "the business with the hugging and kissing," and the defendant's
    act of "kiss hug, kiss hug" throughout his closing.
    Whether the physical intimacy between Weaver and the
    defendant was limited to a brief peck on the cheek or included
    some hugs and kisses, see note 
    3, supra
    , there was no evidence
    that the defendant had planned or engaged in such interaction
    with Weaver to provoke the victim.      There was no evidence that
    the victim was even watching the two, whose interaction was at
    an approximate distance of thirty feet from the victim.      The
    evidence was that the victim spent that time standing with his
    former roommate looking at his cellular telephone, learning how
    37
    to download music.    If anything, the evidence suggested that
    Weaver's conduct -- reaching out, grabbing the defendant by the
    arm, and pulling him back toward her, saying, "no, don't" -- was
    meant to detain the defendant and discourage him from
    approaching the victim.    While a prosecutor may argue reasonable
    inferences to be drawn from the evidence, a prosecutor may not
    argue facts not in evidence or misstate the evidence.       See
    
    Young, 461 Mass. at 206
    .
    C.   Hiding from the defendant.    To further his theme that
    the defendant had gone to the soup kitchen with a "purposeful
    plan" to confront the victim, rather than to drop off Weaver,
    the prosecutor argued that the victim ("a deer in the
    headlights") had gone to the AA meeting specifically to avoid
    the defendant, and the defendant, in turn, had "gone to where
    [the victim] is when he has tried -- you know, when [the victim]
    doesn't want to deal with [the defendant]."     There was
    absolutely no evidence to support this misrepresentation that
    the victim was at the meeting at the soup kitchen seeking refuge
    from the defendant.
    Such "[r]eferences to facts not in the record or
    misstatements of the evidence have been treated as serious
    errors where the misstatement may have prejudiced the
    defendant."   
    Santiago, 425 Mass. at 499
    –500.    See 
    Shelley, 374 Mass. at 469
    (where prosecutor introduced facts not in evidence,
    38
    "we have recognized that the failure to object and possibly
    obtain a curative instruction may be the very thing which
    permits the remarks to have their maximum prejudicial effect").
    iv.   Statements of prosecutor's opinion.   At numerous
    points in his closing, as he had impermissibly in Niemic 
    I, 472 Mass. at 674-675
    , 677, the prosecutor explicitly told the jury
    his own opinion of the defendant's credibility, as well as that
    of some of the other witnesses.   See Commonwealth v. Sanders,
    
    451 Mass. 290
    , 296-297 (2008), citing Commonwealth v. Wilson,
    
    427 Mass. 336
    , 352 (1998), and Commonwealth v. Chavis, 
    415 Mass. 703
    , 713 (1993) (prosecutor may not express his or her personal
    belief in testimony or suggest that he or she has knowledge
    outside record, and may not suggest prosecutor has personal
    knowledge of, or vouch for, credibility of any witness).      See
    also United States v. Torres-Galindo, 
    206 F.3d 136
    , 142 (1st
    Cir. 2000) (vouching includes statements that "invite the jury
    to rely on the prestige of the government and its agents rather
    than the jury's own evaluation of the evidence").
    A prosecutor's statement of personal belief is improper.
    See Commonwealth v. Thomas, 
    401 Mass. 109
    , 115 (1987).     "To
    permit counsel to express his personal belief in the testimony
    (even if not phrased so as to suggest knowledge of additional
    evidence not known to the jury), would afford him a privilege
    not even accorded to witnesses under oath and subject to cross-
    39
    examination.   Worse, it creates the false issue of the
    reliability and credibility of counsel.   This is peculiarly
    unfortunate if one of them has the advantage of official
    backing."   
    Id. at 115-116,
    quoting Commonwealth v.
    De Christoforo, 
    360 Mass. 531
    , 547 (1971) (Tauro, J.,
    dissenting).
    Here, the prosecutor repeatedly stated his own opinion that
    Nason "lie[d]"34 in much of his testimony, and, later told the
    jury Nason had "lied to you folks."35   The prosecutor also
    repeatedly emphasized that the defendant was "lying,"36 as were
    the other defense witnesses.37   The prosecutor also identified,
    as he had impermissibly at the first trial, see Niemic I, 472
    34For example, "So only the words out of his mouth about
    the kind of bad guy [the victim] is to make you think less of
    him. That's not the evidence. You heard the evidence in this
    case. He had a motive. He had a motive because he was angry
    about the girlfriend."
    35For example, "The wheel man who lied to you folks when he
    said [he] didn't know what [the defendant] was going to do as
    he's going to over to talk to [the victim]. Remember?"
    36For example, "[The defendant] lied to us about, "Oh, no.
    I didn't know I stabbed him." He's telling them as he jumped in
    the car, "I stabbed him." He knew he stabbed him. Not swinging
    aimlessly. He knew he stabbed him."
    37The prosecutor argued multiple times in a similar vein
    that the defendant's testimony was contrary to "the evidence."
    At one point, the prosecutor argued that the defendant will
    "keep saying what he wants to say. Get his story out there,
    hoping that there will be a narrative that somebody will buy.
    That's inconsistent with the evidence" (emphasis 
    added). 40 Mass. at 671
    , 673, 675, 676, that testimony which had been given
    by "civilians" (who were not friends of the defendant) and
    therefore was the sole credible evidence.
    The prosecutor of course was entitled to use "enthusiastic
    rhetoric, strong advocacy, and excusable hyperbole" (citation
    omitted).    
    Wilson, 427 Mass. at 350
    .   These statements, however,
    crossed the line between fair and improper argument.     "This line
    of argument . . . further suggested to the jury that the
    testimony of these . . . prosecution witnesses had to be
    believed in toto and that any testimony of the defendant which
    diverged had to be discredited as a lie."     
    Thomas, 401 Mass. at 116
    .    A prosecutor "may not explicitly or implicitly vouch to
    the jury that he [or she] . . . knows that the witness's
    testimony is true."    Commonwealth v. Marrero, 
    436 Mass. 488
    , 501
    (2002), quoting Commonwealth v. Ciampa, 
    406 Mass. 257
    , 265
    (1989).
    Given the absence of objection by defense counsel,38 the
    We are not unaware of apparent deficiencies in defense
    38
    counsel's performance, as already remarked upon here and in
    parts 2.c and 2.d.i, ii, iii, and 
    iv, supra
    . See, for example,
    notes 18, 21, 22, 26, and 
    27, supra
    . Also, counsel's efforts to
    introduce evidence favorable to the defendant often served as
    the bulwark of much of the evidence that was contrary to the
    theory of defense. See note 
    26, supra
    . In addition, counsel
    failed to object to the prosecutor's more than "hard driving"
    cross-examinations; failed to ask for a contemporaneous (or any)
    limiting instruction; and failed to object to the prosecutor's
    persistent interruptions of defense counsel's questions on
    41
    only relevant instruction provided was the general instruction
    that the attorneys' closing arguments are not evidence, and that
    if the jury's memory of the evidence differed, they were to rely
    on their collective memory.   This general instruction was not
    sufficient to explain to the jury why they should not rely on
    the prosecutor's assertions of his own beliefs.   
    Marrero, 436 Mass. at 502
    .   See 
    Torres-Galindo, 206 F.3d at 142
    .   See, e.g.,
    Commonwealth v. Williams, 
    450 Mass. 894
    , 906 (2008) ("In cases
    where a prosecutor improperly has given unsworn testimony that
    went to a critical issue in the case, or improperly has vouched
    for a key Commonwealth witness, where there has been an
    objection [and sometimes not], and where the case against the
    defendant is not otherwise overwhelming [as here], we have
    required a judge to respond to prosecutorial misconduct with
    force and specificity.   A general instruction, as here, will not
    suffice to neutralize the prejudice").   See also Commonwealth v.
    Worcester, 
    44 Mass. App. Ct. 258
    , 266-267 (1998) (new trial
    required based on prosecutor's improper comments on defendant's
    credibility).
    v.   Whether a new trial is warranted.   Given our conclusion
    that portions of the prosecutor's closing were improper, we turn
    direct and cross-examination of many witnesses. Because of the
    result we reach, we need not address these issues further.
    42
    to consideration whether one or more of these improprieties, or
    a combination of all, warrant a new trial.    In determining
    whether a new trial is required because of errors at trial, we
    consider "whether 'defense counsel seasonably objected to the
    arguments at trial . . . whether the judge's instructions
    mitigated the error . . . whether the errors in the arguments
    went to the heart of the issues at trial or concerned collateral
    matters . . . whether the jury would be able to sort out the
    excessive claims made by the prosecutor . . . and whether the
    Commonwealth's case was so overwhelming that the errors did not
    prejudice the defendant.'"    Commonwealth v. Maynard, 
    436 Mass. 558
    , 570 (2002), quoting 
    Santiago, 425 Mass. at 500
    .
    "[T]he cumulative effect of all the errors must be
    'considered in the context of the arguments and the case as a
    whole.'"   Niemic 
    I, 472 Mass. at 673
    , quoting 
    Maynard, 436 Mass. at 570
    .    "Once a properly raised objection to a prosecutor's
    argument is found to be valid, the entire record, including the
    balance of the prosecutor's argument, becomes relevant in
    determining whether the error was prejudicial to the point of
    requiring a reversal of the conviction."     Commonwealth v. Kozec,
    
    399 Mass. 514
    , 523 (1987), citing Commonwealth v. Burke, 
    373 Mass. 569
    , 577 (1977).
    Here, even if no one impropriety alone would mandate a new
    trial, we conclude that the confluence of the asserted errors in
    43
    closing, one of which reiterated the essence of the errors that
    contributed primarily to the need for the second trial, do again
    necessitate a new trial.   Counsel "seasonably objected" to two
    of the arguments -- the substantive use of rebuttal testimony
    and the play to jury sympathy -- and not to the others, which we
    uncovered in our review pursuant to G. L. c. 278, § 33E, but the
    absence of an objection makes no difference in our conclusion.
    Even when reviewed under a substantial likelihood of a
    miscarriage of justice standard,39 the improprieties require a
    new trial, because we cannot be certain that the jury would have
    been able to look at the evidence clearly and reach a decision
    based only on proof beyond a reasonable doubt.   See 
    Bois, 476 Mass. at 34
    , quoting 
    Santiago, 425 Mass. at 501
    .
    As to the second Maynard factor, while there was no
    contemporaneous limiting instruction, the judge gave appropriate
    curative instructions with respect to the two preserved errors
    immediately before her final charge.   See 
    Maynard, 436 Mass. at 570
    ; notes 25 and 
    32, supra
    .   In her final charge, given
    shortly thereafter, the judge provided general instructions that
    39Under G. L. c. 278, § 33E, we review for a substantial
    likelihood of a miscarriage of justice, under which a defendant
    is entitled to relief only "if we have a serious doubt whether
    the result of the trial might have been different had the
    error[s] not been made." Commonwealth v. Russell, 
    439 Mass. 340
    , 345 (2003), quoting Commonwealth v. LeFave, 
    430 Mass. 169
    ,
    174 (1999).
    44
    attorneys' arguments are not evidence, and that the jurors
    should not make a decision based on sympathy or pity.     The judge
    did as much as she could to mitigate the improprieties, which,
    in other circumstances, might be enough.     See 
    Giguere, 420 Mass. at 235
    .
    We have long recognized, however, that not all errors can
    be cured by providing proper instructions.    See Commonwealth v.
    Redmond, 
    370 Mass. 591
    , 597 (1976) (no one error "was
    necessarily so prejudicial that curative instructions were
    useless or that the instructions given were inadequate";
    nonetheless, curative instructions were inadequate in
    circumstances to overcome combination of errors); Commonwealth
    v. DiMarzo, 
    364 Mass. 669
    , 681 (1974) ("It is reasonable for us
    to be confident that in most cases limiting instructions
    accomplish their intended purpose.   Nevertheless, in cases like
    the instant one, where the evidence subject to limitations has
    an extremely high potential for unfair prejudice, we have a duty
    to be skeptical as to the effectiveness of limiting
    instructions"); 
    id., quoting Nash
    v. United States, 
    54 F.2d 1006
    , 1007 (2d Cir.), cert. denied, 
    285 U.S. 556
    (1932) (in some
    contexts, curative instructions "have been characterized by
    Judge Learned Hand as 'the recommendation to the jury of a
    mental gymnastic which is beyond, not only their power, but
    anybody's else'").   See also Commonwealth v. James, 
    424 Mass. 45
    770, 782 (1997), quoting Richardson v. Marsh, 
    481 U.S. 200
    , 208
    (1987) (curative instruction not sufficient to cure prejudice in
    "cases where the codefendant's statement 'expressly
    implicate[s]' the defendant, leaving no doubt that it would
    prove to be 'powerfully incriminating'").   In the circumstances
    here, given the confluence of errors, the inherently highly
    emotional testimony, and the context of the trial, we cannot say
    with confidence that the repeated references to the rebuttal
    testimony and the appeals to sympathy and emotion did not infect
    the jury.
    Turning to the remaining Maynard factors, the improprieties
    went to "the heart of the issues at trial," and were not
    collateral.   See Niemic 
    I, 472 Mass. at 676-677
    .   The
    Commonwealth's case at the defendant's first trial was "not
    overwhelming," 
    id. at 677,
    and in some respects it was weaker at
    the second trial, due to the unavailability of the medical
    examiner who had performed the autopsy and changes in testimony
    or lapses in memory by a number of witnesses.   The improper
    undermining of the theory of defense in effect instructed the
    jury that they reasonably could not believe the defendant's
    testimony.
    At the same time, the improper statements in the
    prosecutor's closing were designed to inflame the jury's
    passions, such that they would feel the need to avenge the
    46
    victim, in a trial where a significant portion of the evidence,
    concerning the efforts to save the victim after he lost
    consciousness, was designed to be emotionally disturbing, in
    order to support the charge of extreme atrocity or cruelty.
    Yet, the statements were not so clearly hyperbole that the jury
    would have been able to identify and sort out "the excessive
    claims made by the prosecutor," and his exhortations that the
    jury could not believe the defendant or any of the "non-
    civilian" testimony.     
    Maynard, 436 Mass. at 570
    , quoting
    
    Santiago, 425 Mass. at 500
    .
    "[T]he prosecutor, in his opening and closing
    statements . . . improperly appealed to the jury's sympathy for
    the victim in a way that may have 'swe[pt] the jurors beyond a
    fair and calm consideration of the evidence."     
    Santiago, 425 Mass. at 493
    –494, quoting Commonwealth v. Perry, 
    254 Mass. 520
    ,
    531 (1926).    The prosecutor's "comments went to the very heart
    of the case.     They struck, and struck impermissibly, at the
    defendant's sole defense, and sought to impeach his only
    witnesses."    
    Shelley, 374 Mass. at 471
    .   "[I]mproper
    suggestions, insinuations, and, especially, assertions of
    personal knowledge [by the prosecutor] are apt to carry much
    weight against the accused when they should properly carry
    none."   
    Id. at 472,
    quoting Berger v. United States, 
    295 U.S. 78
    , 88 (1935).    It was thus unlikely that the jurors would have
    47
    been able to "sort out the excessive claims made by the
    prosecutor" and decide the case on the evidence (citation
    omitted).   See Niemic 
    I, 472 Mass. at 673
    -674.
    Given all this, the improprieties in argument, especially
    the appeals to sympathy, were rendered particularly crucial.
    "[T]hat is the nature of appeals to sympathy:     they do not
    misstate any piece of evidence, but rather obscure the clarity
    with which the jury would look at the evidence and encourage the
    jury to find guilt even if the evidence does not reach the level
    of proof beyond a reasonable doubt.   Thus, the strength of the
    Commonwealth's case is particularly crucial where improper
    appeals to sympathy are made.   Where guilt is clear, we may
    conclude that the overwhelming strength of the evidence led the
    jury to its conclusion, but where the questions are close and
    difficult, we cannot be certain that the jury's conclusion was
    not clouded by the improper appeals and that their verdict was
    based on a dispassionate view of the evidence."

    -502.   Here, the evidence was not overwhelming, and
    the appeals to sympathy are accordingly worrisome.
    We turn to the effect of the improprieties as a whole.      As
    discussed, two of the improprieties in the prosecutor's closing
    are preserved, and are reviewable under a prejudicial error
    standard.   With respect to those uncovered during § 33E review,
    we review for a substantial likelihood of a miscarriage of
    48
    justice, under which a defendant is entitled to relief only "if
    we have a serious doubt whether the result of the trial might
    have been different had the error[s] not been made."
    Commonwealth v. Russell, 
    439 Mass. 340
    , 345 (2003), quoting
    Commonwealth v. LeFave, 
    430 Mass. 169
    , 174 (1999).
    In the context of this case, the use of the rebuttal
    testimony as substantive evidence, and the improper appeals to
    sympathy and emotion were prejudicial to the defendant.    Because
    the statements at issue addressed his intent in approaching the
    victim -- a core issue at trial underpinning his conviction for
    premeditated murder -- and called upon the jury to rely on
    sympathy and emotion, the wrongful use of such evidence
    constituted prejudicial error.   That is so because, in this
    context, the prosecutor's improper statements on seminal issues
    would have been too intertwined with what the prosecutor himself
    described as his "strenuous[]" and "contentious" trial
    strategies for the jury to have engaged in "fair and calm"
    consideration of the evidence (citation omitted).    See 
    Santiago, 425 Mass. at 494
    .   We have serious doubt, particularly when
    these errors are reviewed in combination with those revealed in
    our review under G. L. c. 278, § 33E, "whether the result of the
    trial might have been different had the error[s] not been made."

    Accordingly, a new trial is necessary.

    3.     Conclusion.   "We take no pleasure, in fact we harbor a
    degree of concern, that a time-consuming and costly retrial must
    be held. . . .    Our task, not always an easy one, is to preserve
    the interests of justice, both for the Commonwealth and the
    accused.    On this record, the risk of a miscarriage of justice
    is too great for us to let stand the defendant's conviction of
    murder . . . ."   
    Kater, 388 Mass. at 534
    .
    The verdict of guilty of murder in the first degree is
    vacated and set aside.    The matter is remanded to the Superior
    Court, where the Commonwealth again may accept a reduction in
    the verdict to manslaughter, or once again may retry the
    defendant on the murder charge.
    So ordered.
