    A pretrial motion to suppress evidence was heard by Daniel
    A. Ford, J.; the cases were tried before him; and a motion for a
    new trial was considered by him.
    The Supreme Judicial Court on its own initiative
    transferred the case from the Appeals Court.

    Jason D. Frank, Vanessa M. Brown, & Chauncey B. Wood, for
    Massachusetts Association of Criminal Defense Lawyers, amicus
    curiae, submitted a brief.
    BUDD, J.   The defendant, Raul Matta, fled when a police
    officer attempted to question him as a result of a tip received
    regarding a firearm in a motor vehicle.   After pursuing and
    arresting the defendant, police recovered a plastic bag
    containing heroin that the defendant had thrown onto a
    pedestrian walkway; several more small bags of heroin were found
    at the defendant's feet.   The defendant was charged with
    possession of heroin with intent to distribute (second offense)
    in violation of G. L. c. 94C, § 32 (b); and with committing the
    crime within one hundred feet of a public park in violation of
    G. L. c. 94C, § 32J (§ 32J), the "park zone statute."1    A judge
    in the Superior Court denied the defendant's motion to suppress
    the evidence, and the defendant was subsequently found guilty of
    each of the above offenses.   His motion for a new trial premised
    on ineffective assistance of counsel was denied by the same
    judge who had decided the motion to suppress and presided over
    the trial.
    We transferred the defendant's consolidated appeal to this
    court on our own motion, and we now affirm the defendant's
    1 The defendant also was charged with resisting arrest, but
    that charge was dismissed on the defendant's motion for a
    required finding of not guilty.
    3
    conviction of possession of heroin with intent to distribute,
    reverse the denial of the defendant's motion for a new trial on
    the § 32J charge, and vacate the conviction of a violation of
    § 32J.   In so doing, however, we conclude that intent to commit
    the underlying drug crime is sufficient to violate § 32J,
    without additional proof of scienter of park boundaries;
    further, we conclude that whether a particular location is a
    "park" pursuant to the statute is a matter for the fact finder
    to determine.
    Background.   For the purposes of the motion to suppress, we
    present the facts found by the motion judge supplemented by
    uncontroverted facts from the record.   Commonwealth v. Jones-
    Pannell, 
    472 Mass. 429
    , 431 (2015).   On November 5, 2015, in the
    late afternoon, Holyoke police received two telephone calls from
    an unknown source indicating that the caller had observed
    someone place a firearm under the front seat of a black motor
    vehicle with two male and two female occupants.   The motor
    vehicle was parked in an area of Holyoke known for violent
    crime, drug sales, and shootings.
    Upon arrival, approximately three to four minutes after
    officers were dispatched to the scene, one of the officers
    observed a parked dark green Honda with two people inside.    The
    officer, who was driving a marked cruiser, parked directly
    behind the vehicle without activating the lights or siren.    As
    4
    the officer got out of the cruiser, he observed the individual
    seated in the passenger seat, later identified as the defendant,
    get out of the vehicle and reach with both hands to the right
    side of his body and adjust his waistband.     The defendant
    thereafter began walking toward bushes that were away from the
    sidewalk.   The officer then called out in substance, "Hey, come
    here for a second."    At that point, the defendant made eye
    contact with the officer and immediately began to run.       As the
    defendant ran, he held onto his waistband.      The officer yelled
    out for the defendant to stop, and then gave chase.
    As the defendant ran behind a nearby apartment building, he
    threw a plastic bag over a chain link fence approximately eight
    feet high onto a pedestrian walkway.     The defendant was
    apprehended by multiple officers as he attempted to scale the
    fence, and the group fell to the ground.      When the defendant was
    arrested, there were small wax baggies on the ground at his
    feet.   The plastic bag retrieved from the other side of the
    fence also contained smaller wax baggies.     One hundred twenty-
    nine baggies were recovered in total.     A sample of the contents
    of the baggies was found to be heroin.
    Discussion.   1.    Motion to suppress.    The defendant argues
    that the officer did not have reasonable suspicion to stop him,
    and thus his motion to suppress the narcotics seized as a result
    should have been allowed.    See Commonwealth v. Franklin, 456
    
    5 Mass. 818
    , 820 (2010) (evidence obtained as result of unlawful
    seizure is inadmissible).
    "When reviewing the denial of a motion to suppress, this
    court accepts 'the judge's subsidiary findings of fact absent
    clear error and leave[s] to the judge the responsibility of
    determining the weight and credibility to be given oral
    testimony presented at the motion hearing.'     Commonwealth v.
    Contos, 
    435 Mass. 19
    , 32 (2001), quoting Commonwealth v. Eckert,
    
    431 Mass. 591
    , 592-593 (2000).     'We conduct an independent
    review of the judge's application of constitutional principles
    to the facts found.'     Commonwealth v. Hoose, 
    467 Mass. 395
    , 400
    (2014)."    Commonwealth v. Pinto, 
    476 Mass. 361
    , 363 (2017).
    Article 14 of the Massachusetts Declaration of Rights
    provides that "[e]very subject has a right to be secure from all
    unreasonable searches, and seizures, of his person, his houses,
    his papers, and all his possessions."     An investigatory stop or
    "seizure" by police is justified under art. 14 if police have
    reasonable suspicion at the time of the stop to conduct it.       See
    Commonwealth v. Phillips, 
    452 Mass. 617
    , 626 (2008), and cases
    cited.     Thus, we must determine (1) at what point the stop
    occurred; and (2) whether the officer had reasonable suspicion
    for the stop at that time.     
    Franklin, 456 Mass. at 820
    .
    a.     Seizure.   Here, the defendant argues that the seizure
    occurred when the police officer called out, "[H]ey, come here
    6
    for a second," as the defendant began walking away from the
    officer.     The Commonwealth argues that the seizure occurred
    moments later, after the defendant began to flee, when the
    officer ordered the defendant to stop running away.      As
    explained infra, we agree with the Commonwealth.
    i.    Standard.    "[N]ot every encounter between a law
    enforcement official and a member of the public constitutes [a
    seizure]."    
    Franklin, 456 Mass. at 820
    , quoting Commonwealth v.
    Lopez, 
    451 Mass. 608
    , 611 (2008).      We have long held that
    "[p]olice have seized a person in the constitutional sense 'only
    if, in view of all the circumstances surrounding the incident, a
    reasonable person would have believed that he [or she] was not
    free to leave.'"       Commonwealth v. Barros, 
    435 Mass. 171
    , 173-174
    (2001), quoting United States v. Mendenhall, 
    446 U.S. 544
    , 554
    (1980) (opinion of Stewart, J.).      See Florida v. Royer, 
    460 U.S. 491
    , 502 (1983).       See also Commonwealth v. Borges, 
    395 Mass. 788
    , 791 (1985).2      However, because civilians rarely feel "free
    2 In California v. Hodari D., 
    499 U.S. 621
    , 628-629 (1991),
    the United States Supreme Court distanced itself from the
    Mendenhall-Royer line of cases, holding that seizure requires
    more than a show of authority leading to a reasonable belief
    that one is not free to leave -- there must also be submission
    to that show of authority. See United States v. Dubose, 
    579 F.3d 117
    , 121 (1st Cir. 2009), cert. denied, 
    562 U.S. 1016
    (2010) ("when an officer makes a show of authority instead [of
    using physical force], the person is not seized until the person
    submits to the show of authority by complying with the officer's
    instruction"). In interpreting art. 14 of the Massachusetts
    Declaration of Rights, we have rejected the Hodari D. approach.
    7
    to leave" a police encounter, a true application of the test
    would result in nearly every police inquiry being deemed a
    seizure in the constitutional sense.3   See 4 W.R. LaFave, Search
    and Seizure § 9.4(a), at 580 (5th ed. 2012) ("[I]f the ultimate
    See Commonwealth v. Stoute, 
    422 Mass. 782
    , 786-787 (1996). See
    also Commonwealth v. Franklin, 
    456 Mass. 818
    , 821-822 (2010)
    ("seizure for art. 14 purposes may be effectuated by police
    conduct that falls short of the physical detention of the
    suspect").
    We note, however, that Federal law has not abandoned the
    "free to leave" test entirely. See Brendlin v. California, 
    551 U.S. 249
    , 254-255 (2007), and cases cited. That is, in cases
    involving seizure via submission to a show of authority, the
    show of authority must still be evaluated through the
    Mendenhall-Royer standard. See, e.g., United States v. Stover,
    
    808 F.3d 991
    , 995-996 (4th Cir. 2015), cert. denied, 
    137 S. Ct. 241
    (2016) ("If an interaction is not consensual, i.e., if a
    reasonable person would not have felt free to terminate it, then
    the Fourth Amendment guards against unreasonable seizures. In
    such cases, however, the seizure inquiry does not end. . . .
    [A] court must also ascertain whether and when the subject of
    the seizure actually acquiesced to that authority"). See also
    United States v. Tanguay, 
    918 F.3d 1
    , 6 (1st Cir. 2019), and
    cases cited.
    3 "[O]ur law guards a person's freedom to speak or not to
    speak to a police officer. A person also may choose to walk
    away, avoiding altogether any contact with police."
    Commonwealth v. Warren, 
    475 Mass. 530
    , 538 (2016). However,
    although legally a person may be free to end a "voluntary"
    police encounter, in reality when an officer makes inquiry of an
    individual, he or she may not feel free to leave. That is, the
    law on what constitutes an "objectively" coercive situation does
    not line up with empirical evidence on the matter. See Kessler,
    Free to Leave? An Empirical Look at the Fourth Amendment's
    Seizure Standard, 99 J. Crim. L. & Criminology 51, 73 (2009);
    Smith, Dolgoff, & Speer, Testing Judicial Assumption of the
    "Consensual" Encounter: An Experimental Study, 14 Fla. Coastal
    L. Rev. 285, 304-305 (2013) (among participants in "consensual"
    police encounter, majority did not feel free to leave or did not
    know of right to leave).
    8
    issue is perceived as being whether the suspect 'would feel free
    to walk away,' then virtually all police-citizen encounters must
    in fact be deemed to involve a Fourth Amendment seizure.     The
    Mendenhall-Royer standard should not be given such a literal
    reading as to produce such a result" [footnotes omitted]).4
    A review of our case law reveals that rather than focusing
    primarily on whether a reasonable person would have believed
    that he or she was free to leave, we look at the totality of the
    circumstances to determine whether a member of law enforcement
    has "engaged in some show of authority" that a reasonable person
    would consider coercive; that is, behavior "which could be
    expected to command compliance, beyond simply identifying [him-
    or herself] as police" (quotation and citation omitted).
    Commonwealth v. Sanchez, 
    403 Mass. 640
    , 644 (1988).
    4 That the "free to leave" test is somewhat of a misnomer
    has not escaped the notice of courts. See, e.g., United States
    v. Cardoza, 
    129 F.3d 6
    , 16 (1st Cir. 1997) ("We recognize, of
    course, the import of [the defendant]'s observation that few
    people . . . would ever feel free to walk away from any police
    question"); United States v. Tavolacci, 
    895 F.2d 1423
    , 1425
    (D.C. Cir. 1990), citing Butterfoss, Bright Line Seizures: The
    Need for Clarity in Determining When Fourth Amendment Activity
    Begins, 79 J. Crim. L. & Criminology 437, 439 (1988)
    (acknowledging criticism that "free to leave" test is
    "artificial" and "based on a false assumption that ordinary
    citizens believe they are normally free to cut police inquiries
    short"); People v. Spicer, 
    157 Cal. App. 3d 213
    , 218 (1984)
    (characterizing one's freedom to disregard police questioning
    and walk away as "legal fiction").
    9
    Thus, rather than attempting to determine whether a
    reasonable person would believe he or she was free to leave, in
    our view, the more pertinent question is whether an officer has,
    through words or conduct, objectively communicated that the
    officer would use his or her police power to coerce that person
    to stay.   See 
    Barros, 435 Mass. at 175-176
    (question is whether
    officer was "communicating what a reasonable person would
    understand as a command that would be enforced by the police
    power").   See also Commonwealth v. Sykes, 
    449 Mass. 308
    , 311
    (2007), quoting Terry v. Ohio, 
    392 U.S. 1
    , 19 n.16 (1968)
    (seizure occurs "[o]nly when the officer, by means of physical
    force or show of authority, has in some way restrained the
    liberty of a citizen").5   If applied literally, the Mendenhall-
    5 The United States Court of Appeals for the First Circuit
    has also acknowledged the internal contradiction in the
    doctrine, and the court has adopted an inquiry that looks to
    whether the police officer objectively communicated that he or
    she is "exercising his or her official authority to restrain the
    individual's liberty of movement" (citation omitted). See
    
    Tanguay, 918 F.3d at 6
    , and cases cited; United States v.
    Cardoza, 
    129 F.3d 6
    , 16 (1st Cir. 1997). Under this approach,
    courts still look to the "totality of the circumstances" as
    interpreted through the "reasonable person," but with special
    attention paid to the officer's words and actions, and the
    message conveyed therein. See United States v. Ford, 
    548 F.3d 1
    , 5 (1st Cir. 2008), cert. denied, 
    558 U.S. 815
    (2009). See
    also United States v. Mendenhall, 
    446 U.S. 544
    , 554 (1980)
    ("Examples of circumstances that might indicate a seizure, even
    where the person did not attempt to leave, would be the
    threatening presence of several officers, the display of a
    weapon by an officer, some physical touching of the person of
    the citizen, or the use of language or tone of voice indicating
    that compliance with the officer's request might be compelled").
    10
    Royer standard would require a court to treat "seizure" as a
    state of mind induced by the mere presence of law enforcement,
    rather than a discrete and intentional act of law enforcement.
    See Black's Law Dictionary 1631 (11th ed. 2019) (defining
    "seize" as "[t]o forcibly take possession [of a person or
    property]").   Cf. California v. Hodari D., 
    499 U.S. 621
    , 625
    (1991), quoting Thompson v. Whitman, 
    85 U.S. 457
    , 471 (1873) ("A
    seizure is a single act, and not a continuous fact").     Cf. also
    Nieves v. McSweeney, 
    241 F.3d 46
    , 55 (2001) (pretrial release
    conditions do not constitute seizure because seizure is
    "generally a discrete event, quintessentially an arrest, . . .
    or at least a physical detention").    In other words, while the
    attending circumstances of a police encounter are relevant, a
    "seizure" must arise from the actions of the police officer.
    The question whether one believes he or she is free to walk
    away from a police encounter, as compared to whether one
    believes he or she would be coerced to stay, is not a
    distinction without a difference.     Police officers are free to
    make noncoercive inquiries of anyone they wish.    See
    Commonwealth v. Murdough, 
    428 Mass. 760
    , 763 (1999).     And, as
    discussed in note 
    3, supra
    , although not legally obligated, few
    As the First Circuit has stated, "Discerning such an objective
    communication of authority is easiest when the officer expressly
    asserts it through a command." See 
    Tanguay, supra
    , and cases
    cited.
    11
    civilians feel as if they could discontinue an encounter with a
    law enforcement officer, let alone ignore an inquiry from one.6
    Indeed, the police depend on a degree of civilian compliance to
    maintain public safety and carry out criminal investigations.
    See Strange v. Commonwealth, 
    269 S.W.3d 847
    , 851 (Ky. 2008).     In
    short, because, in most situations, a reasonable person would
    not believe that he or she was free to leave during a police
    encounter, using that standard does not produce the information
    necessary to determine whether a seizure has occurred.     Rather,
    the inquiry must be whether, in the circumstances, a reasonable
    person would believe that an officer would compel him or her to
    stay.
    Although this is a different question from what we
    heretofore have asked, the analysis takes the same circumstances
    into consideration.   Whether an encounter between a law
    enforcement official and a member of the public constitutes a
    noncoercive inquiry or a constitutional seizure depends upon the
    facts of the particular case.   See 
    Sykes, 449 Mass. at 311
    ,
    citing Commonwealth v. Thinh Van Cao, 
    419 Mass. 383
    , 387, cert.
    denied, 
    515 U.S. 1146
    (1995) ("The nature of an encounter
    between a citizen and a law enforcement official is necessarily
    6 We note that those in doubt as to whether they are free to
    discontinue an encounter with the police may ask the officer at
    any point during the encounter if they are free to leave.
    12
    fact specific and requires careful examination of the attending
    circumstances").     The difference is one of emphasis -- that is,
    even though most people would reasonably feel that they were not
    "free to leave" in any police encounter, the coercion must be
    objectively communicated through the officer's words and actions
    for there to be a seizure.    See 
    Barros, 435 Mass. at 175-176
    .
    ii.   Application.     Here, the police officer parked his
    cruiser behind the vehicle in which the defendant was a
    passenger.   The two men got out of their vehicles in unison, and
    the defendant began walking away from the officer.     As the
    defendant did so, the officer said, in substance, "Hey, come
    here for a second."     The officer and the defendant "locked eyes
    for a moment," and then the defendant began running away.       The
    officer instructed the defendant to stop, and then gave chase
    when the defendant failed to comply.
    We begin with the initial attempt the officer made to
    engage the defendant.     Although we have acknowledged the
    difference between questions and orders, see, e.g., 
    Lopez, 451 Mass. at 610
    ("A question is an inquiry; an order is a command.
    A question requests an answer, while an order demands
    obedience"), we never have held that a direct command from a
    police officer to submit to his or her authority automatically
    effects a seizure.    Instead, we look to whether an officer has
    "communicat[ed] what a reasonable person would understand as a
    13
    command that would be enforced by the police power."    
    Barros, 435 Mass. at 176
    .
    Thus, we have concluded that no seizure has taken place
    when an officer got out of his marked cruiser and said to
    defendant, "Hold on a second, I want to talk to you."
    Commonwealth v. Martin, 
    467 Mass. 291
    , 301, 303 (2014).     See
    
    Lopez, 451 Mass. at 610
    (officer motioning at defendant to come
    to him and asking, "Can I speak with you?" was not seizure).        In
    contrast, we have concluded that where a defendant chooses to
    ignore verbal attempts by police to speak with him, and officers
    persist by issuing a subsequent order, that subsequent order
    constitutes a seizure.   See 
    Jones-Pannell, 472 Mass. at 431
    (after defendant failed to respond to police requests, officer
    called out, "Wait a minute"); 
    Barros, 435 Mass. at 172
    (after
    being ignored, officer got out of vehicle, walked up to
    defendant with two other officers and said, "Hey you.     I wanna
    talk to you.   Come here" [emphasis added]).
    Here, the officer's words, "Hey, come here for a second,"
    were not what "a reasonable person would understand as a command
    that would be enforced by the police power."   
    Barros, 435 Mass. at 176
    .   The record here shows that, at this point, the officer
    had made only one request, compare 
    id., and had
    not activated
    any lights or sirens, compare Commonwealth v. Smigliano, 
    427 Mass. 490
    , 492-492 (1998), or otherwise intimidated the
    14
    defendant, compare 
    Sykes, 449 Mass. at 311
    , 313.      Further,
    although the officer began walking toward the defendant, the
    officer did not "impede or restrict the defendant's freedom of
    movement."    Barros, supra at 174.   For that reason, we conclude
    that the defendant was not seized at the point at which the
    officer first called out to him.
    The defendant was seized, however, once the officer ordered
    him to stop, and then chased him.     See Commonwealth v. Thibeau,
    
    384 Mass. 762

    b.   Reasonable suspicion.   We turn next to whether the
    officer had reasonable suspicion to believe that the defendant
    "was committing, had committed, or was about to commit a crime"
    at the time of the seizure.     
    Martin, 467 Mass. at 303

    Reasonable suspicion "must be grounded in 'specific, articulable
    facts and reasonable inferences [drawn] therefrom' rather than
    on a 'hunch.'"    Commonwealth v. DePeiza, 
    449 Mass. 367
    , 371
    (2007), quoting Commonwealth v. Scott, 
    440 Mass. 642
    , 646
    (2004).     "The facts and inferences underlying the officer's
    suspicion must be viewed as a whole when assessing the
    reasonableness of his acts."     
    Sykes, 449 Mass. at 314
    , quoting
    15
    
    Thibeau, 384 Mass. at 764
    .    That is, "a combination of factors
    that are each innocent of themselves may, when taken together,
    amount to the requisite reasonable belief that a person has, is,
    or will commit a particular crime" (quotation and citation
    omitted).   Commonwealth v. Meneus, 
    476 Mass. 231
    , 236 (2017).
    Based upon the judge's findings, at the time of the stop,
    the officer was aware of the anonymous tip regarding a concealed
    firearm in a motor vehicle in an area "known for violent crime,
    drug sales, and shootings."   The officer, who had gotten out of
    his cruiser, observed the defendant get out of the automobile in
    which he was seated, adjust the right front area of his
    waistband with both hands, and walk toward some bushes "not on
    the sidewalk[,] where one would expect a person to walk."      When
    the officer called out to the defendant, the two looked at one
    another, and then the defendant began to run.   Although the
    question is a close one, we conclude that here the circumstances
    existing at the time of the stop provided reasonable suspicion
    for that stop.
    We begin by noting that carrying a concealed firearm, by
    itself, is not a crime.   
    DePeiza, 449 Mass. at 373
    .   Thus, the
    caller's tip "suggesting a concealed firearm, with nothing more,
    [did] not provide reasonable suspicion for a stop."7   
    Id., citing 7
    There were also issues with the reliability of the
    anonymous tip itself. See generally Commonwealth v. Mubdi, 456
    16
    Commonwealth v. Alvarado, 
    423 Mass. 266
    , 269 (1996);
    Commonwealth v. Couture, 
    407 Mass. 178
    , 183, cert. denied, 
    498 U.S. 951
    (1990).    Compare Commonwealth v. Haskell, 
    438 Mass. 790
    , 793-794 (2003) (reasonable suspicion existed where
    defendant was observed loading handgun shortly before 2 A.M. in
    high crime area).
    Similarly, the defendant's adjustment of his waistband
    alone did not create reasonable suspicion for a seizure.     It is
    not uncommon for anyone to adjust his or her clothing upon
    getting out of a motor vehicle.   See generally United States v.
    Gray, 
    213 F.3d 998
    , 1001 (8th Cir. 2000) ("Too many people fit
    this description for it to justify a reasonable suspicion of
    criminal activity").   However, the judge credited the officer's
    Mass. 385, 395-396 (2010), quoting Commonwealth v. Lopes, 
    455 Mass. 147
    , 155-156 (2009); Commonwealth v. Depina, 
    456 Mass. 238
    , 243 (2010). The caller reported that the firearm was in a
    black vehicle with four occupants, including two females and two
    males, with one of the females in the driver's seat. The
    caller's description of the vehicle varied, including a Honda, a
    Toyota, and a vehicle with lights that flip up and down. When
    an officer arrived a few minutes following the caller's tip, he
    found a dark green Honda with two occupants, one of whom
    appeared to be a female in the driver's seat; the gender of the
    individual in the passenger seat could not be immediately
    ascertained. Both individuals were in fact male; however, the
    driver had a ponytail. We note that although there were
    discrepancies between the details provided by the anonymous
    caller and the observations made by the officer upon arriving to
    the area, police "must be allowed to take into account of the
    possibility that some descriptive facts supplied . . . may be in
    error" (citation omitted). Commonwealth v. Emuakpor, 57 Mass.
    App. Ct. 192, 198 (2003).
    17
    testimony that based upon the officer's experience, people who
    carry unlicensed firearms often carry them inside a waistband,
    and that the officer became concerned that the defendant was
    carrying an unlicensed firearm when the defendant adjusted the
    right side of his waistband using both hands.8
    In addition, the officer's concern was heightened when the
    defendant "began walking towards bushes, not on the sidewalk
    where one would expect a person to walk," and, when the officer
    called out to the defendant, the defendant began to run away,
    holding his waistband as he ran.   "[N]ervous or furtive
    movements do not supply reasonable suspicion when considered in
    isolation," 
    DePeiza, 449 Mass. at 372
    ; nor does seeking to avoid
    contact with police, Commonwealth v. Warren, 
    475 Mass. 530
    , 538-
    8 We note that ordinarily, when an officer relies on his or
    her training and experience to draw an inference or conclusion
    about an observation made, the officer must explain the specific
    training and experience that he or she relied on and how that
    correlates to the observations made. See United States v.
    Walker, 
    324 F.3d 1032
    , 1037 (8th Cir.), cert. denied, 
    540 U.S. 898
    (2003); United States v. Johnson, 
    171 F.3d 601
    , 604 (8th
    Cir. 1999). Here, the officer did not testify specifically
    that, in his training and experience, the adjustment of one's
    waistband in the way described indicates that the person may be
    carrying an unlicensed firearm. Compare Commonwealth v.
    DePeiza, 
    449 Mass. 367
    , 368, 373-374 (2007) ("As part of their
    training . . . officers had learned that [defendant's]
    distinctive 'straight arm' gait was one sign of a person
    carrying a firearm by pressing it against his body with the
    stiff arm"). However, as the officer testified that in his
    experience people carry unlicensed firearms in their waistband,
    the fact that the defendant clutched his waistband as he ran
    could be considered as part of the reasonable suspicion
    calculus.
    18
    539 (2016).    However, those details could be combined with the
    other circumstances present in this case in the reasonable
    suspicion calculus.    See, e.g., 
    Sykes, 449 Mass. at 314
    , and
    cases cited.
    The officer also properly could consider the fact that the
    encounter took place in a high crime neighborhood.    We have held
    repeatedly that "[j]ust being in a high crime area is not enough
    to justify a stop."    Commonwealth v. Grandison, 
    433 Mass. 135
    ,
    139 (2001).    However, the fact that a particular area is known
    for "violent crime, drug sales, and shootings," as was the case
    here, may be taken into account as a factor in the reasonable
    suspicion analysis.    See Commonwealth v. Johnson, 
    454 Mass. 159
    ,
    163 (2009).
    Finally, although the defendant's flight from the officer
    is not enough on its own for an "individualized suspicion that
    the defendant was involved in [a] crime," see 
    Warren, 475 Mass. at 538
    , it is a factor that may be considered in the reasonable
    suspicion calculus in appropriate circumstances.     See 
    Sykes, 449 Mass. at 314
    .   Considered in isolation, none of the above
    factors would have been enough to create reasonable suspicion
    that the defendant had committed, was committing, or was about
    to commit a crime.    However, taken together, the circumstances
    presented added up to reasonable suspicion for an investigatory
    stop.   See 
    DePeiza, 449 Mass. at 371-372
    .

    2.     General Laws c. 94C, § 32J.9   As a result of throwing a
    bag of heroin over a fence onto what is known as Ely Pedestrian
    Walkway (walkway), the defendant was convicted of committing a
    drug offense within one hundred feet of a park (park zone)
    pursuant to § 32J.     The defendant makes three claims with
    respect to this conviction.     First, he argues that § 32J
    includes a scienter element as it pertains to the park zone
    provision and that the Commonwealth failed to prove the
    defendant knowingly violated the provision.      Second, the
    defendant argues that the walkway onto which he threw the heroin
    was not a park within the meaning of the statute.      Third, the
    defendant contends in a motion for a new trial that even if the
    walkway was a park under § 32J, it was incorrectly identified in
    the indictment as Ely Court Park, which is a separate tract of
    land not adjacent to the walkway, and that his trial counsel was
    ineffective for failing to raise the issue of variance of proof
    at trial.
    After review, we conclude that with respect to the "public
    park or playground" provision of § 32J, the intent to commit the
    9 General Laws c. 94C, § 32J (§ 32J), commonly is known as
    the "school zone statute" because, as originally enacted in
    1989, it punished certain drug offenses that occurred within a
    designated number of feet of a school zone. See St. 1989,
    c. 227, § 2. As discussed infra, the statute was amended in
    1993 to include public parks and playgrounds. See St. 1993,
    c. 335.
    20
    underlying drug crime is sufficient, without additional proof of
    knowledge of park or playground boundaries required.   We further
    conclude that whether an area of land is a public park under
    § 32J is a question of fact properly left to the fact finder.
    Finally, we conclude that the defendant's trial counsel was
    ineffective with respect to failing to raise the variance
    between the park named in the indictment and the evidence
    presented at trial.
    a.   Mens rea.   Section 32J provides in relevant part:
    "Any person who violates the provisions of [§§ 32, 32A,
    32B, 32C, 32D, 32E, 32F, or 32I][10] while in on, or within
    300 feet of the real property comprising a public or
    private accredited preschool, accredited headstart
    facility, elementary, vocational or secondary school if the
    violation occurs between 5:00 A.M. and midnight, whether or
    not in session, or within [one hundred feet] of a public
    park or playground shall be punished by a term of
    imprisonment . . . . Lack of knowledge of school
    boundaries shall not be a defense to any person who
    violates the provisions of this section." (Emphases
    added.)
    G. L. c. 94C, § 32J, as appearing in St. 2018, c. 69, § 57.11
    The original version of § 32J, enacted in 1989, referred to drug
    offenses committed on the property of or within a specified
    10These sections of G. L. c. 94C, otherwise known as the
    Controlled Substances Act, govern the unauthorized manufacture,
    distribution, and dispensing of controlled substances, see
    §§ 32, 32A, 32B, 32C, 32D, and 32E, as well as sale to minors,
    see § 32F, and the sale of drug paraphernalia, see § 32I.
    11Since the time of the defendant's alleged offense in
    2015, § 32J was rewritten, see St. 2018, c. 69, § 57, but the
    provisions at issue here remain substantially unchanged.
    21
    distance of schools (school zones).12   See St. 1989, c. 227, § 2.
    Not long after its passage, we confirmed that § 32J "comprises,
    in part, an aspect of strict liability," Commonwealth v.
    Peterson, 
    476 Mass. 163
    , 165-166 (2017), and that as such it did
    not violate the due process clause, see Commonwealth v. Alvarez,
    
    413 Mass. 224
    , 228-229 (1992).13   See also Commonwealth v.
    Roucoulet, 
    413 Mass. 647
    , 650-651 (1992).
    12Originally included were "public or private elementary,
    vocational, or secondary" schools. St. 1989, c. 227, § 2. In
    1998, § 32J was amended to include preschools and accredited
    headstart programs. St. 1998, c. 194, § 146.
    13In concluding that § 32J did not violate the due process
    clause, we pointed out that
    "§ 32J is not totally void of any mens rea requirement.
    Before a conviction can be obtained thereunder the
    Commonwealth must prove the defendant guilty of a predicate
    drug-dealing offense requiring mens rea -- in this case the
    possession of cocaine with intent to distribute. Section
    . . . 32J thus imposes liability only on someone who knows
    he is dealing in drugs and requires the dealer to proceed
    at his peril with respect to the proximity of a school."
    Commonwealth v. Alvarez, 
    413 Mass. 224
    , 229-230 (1992).
    Further, we noted that § 32J is similar to "other criminal
    statutes which punish an underlying violation committed with
    mens rea and consider the offense aggravated by a fact of which
    the defendant may not have express knowledge." 
    Id. at 230.
    See
    G. L. c. 269, § 12E (discharge of firearm within 500 feet of
    dwelling; no requirement of knowledge of distance); G. L.
    c. 94C, § 32E (increasing mandatory minimum terms based on
    weight of controlled substances with no requirement of knowledge
    of weight of substance). But see Commonwealth v. Brown, 
    479 Mass. 600
    , 607-608 (2018) (Commonwealth must prove that
    defendant knew that unlawful firearm was loaded with ammunition
    for conviction under G. L. c. 269, § 10 [n], because unlawful
    possession of ammunition is lesser included offense).
    22
    In 1993, when the Legislature amended § 32J to bar, in
    addition, drug offenses within park zones, the amendment did not
    alter the last sentence of the statute.    See St. 1993, c. 335.
    The defendant contends that because § 32J explicitly bars
    "[l]ack of knowledge of school boundaries," but not lack of park
    boundaries, as a defense, we are to infer that a defendant
    therefore can assert the latter as a defense.    This position
    conflicts with the purpose of, and prior decisions interpreting,
    § 32J.
    We begin by noting that the express inclusion of one thing
    does not imply the exclusion of another.     See Commonwealth v.
    Garvey, 
    477 Mass. 59
    , 65 (2017).    Thus, it is not necessarily
    the case that because § 32J specifically excludes lack of
    knowledge of school zones but not park zones as a defense to the
    statute, that the latter is an available affirmative defense.
    Our holding that § 32J lacks a knowledge requirement with
    regard to school boundaries did not rest solely on the last
    sentence of § 32J.     Commonwealth v. Lawrence, 
    69 Mass. App. Ct. 596
    , 600 (2007).     See 
    Alvarez, 413 Mass. at 229
    ("Even in the
    absence of specific language such as the language that appears
    in § 32J, we have construed criminal statutes which authorize
    the imposition of serious sentences to permit conviction without
    proof of mens rea . . .").    In Roucoulet, we noted with respect
    to the school zone provision of § 32J:
    23
    "By its express terms, a violation is made out if a
    defendant is shown to have committed one of the enumerated
    acts that constitute crimes under G. L. c. 94C 'while in or
    on, or within' 1,000 feet of a school. The quoted words
    are clearly meant to fix the location where the predicate
    crime must take place. General Laws c. 94C, §§ 32A and
    32E, which in relevant part make criminal the possession
    with intent to distribute cocaine, do not require for
    conviction that a defendant have an intent to distribute
    within any specific area. Considered term by term, § 32J
    contemplates a violation in three instances -- when one of
    the identified drug crimes is committed (a) in a school;
    (b) on school property; or (c) within 1,000 feet of school
    property. 'After the elements of [the predicate] offense
    have been established, one need only take out the tape
    measure to see if [the school zone provision of § 32J] has
    been violated.'"
    
    Roucoulet, 413 Mass. at 650-651
    , quoting State v. Ivory, 
    124 N.J. 582
    , 593 (1991).   The same reasoning pertains to the park
    zone provision of the statute, which applies when a drug
    violation occurs "within [one hundred] feet of a public park or
    playground."   G. L. c. 94C, § 32J.   That is, by the provision's
    plain language § 32J is violated any time one of the enumerated
    drug offenses occurs in that specified location.    No scienter
    requirement is stated or implied.     See Commonwealth v. LeBlanc,
    
    475 Mass. 820
    , 821 (2016) ("Clear and unambiguous language is
    conclusive as to legislative intent").
    This result is in keeping with the legislative intent of
    the statute.   "It is well settled, through legislative history
    and two decades of decisional law examining that history, that
    the purpose of G. L. c. 94C, [§] 32J, is to protect children
    from the harmful impact of drug dealing."     Commonwealth v.
    24
    Peterson, 
    476 Mass. 163
    , 168 (2017).    Just as in the case of a
    school zone, the distribution of drugs within a park zone
    creates a potentially dangerous situation for children
    regardless of a drug dealer's knowledge or intent to do so in
    that location.14    See 
    Roucoulet, 413 Mass. at 651
    , quoting 
    Ivory, 124 N.J. at 594-595
    ("Clearly, the Legislature intended to
    create drug-free zones of safety where children could be, learn
    and play free of the potential infection of drugs.    One
    contaminating these safety zones is liable, regardless of
    whether he or she intended to infect those here or others
    elsewhere").
    Finally, we note that the argument proffered by the
    defendant already has been considered and rejected by the
    Appeals Court.     In 
    Lawrence, 69 Mass. App. Ct. at 600
    , the court
    held that the strict liability aspect of § 32J applies to
    preschools, concluding that "the Legislature properly forwent
    any element of scienter with respect to whether a defendant had
    14The defendant points out that, in its original form,
    § 32J disproportionately affected urban communities resulting in
    racial disparities, and goes on to argue that construing § 32J
    to permit conviction without proof of mens rea is in
    contravention of the Legislature's intent to reduce those
    disparities. We disagree. In 2012, the Legislature amended
    § 32J to decrease the radius of the school zone from 1,000 feet
    to 300 feet specifically to address those disparities. See
    Commonwealth v. Bradley, 
    466 Mass. 551
    , 552 (2013). It made no
    other amendments to the statute in this regard; in particular,
    the Legislature left the mens rea requirement unchanged.
    25
    an intent to commit the predicate offense within any specific
    area."   Although the Legislature has amended § 32J more than
    once since that time, it has not made any changes with regard to
    mens rea.   See St. 2010, c. 256, § 72; St. 2012, c. 192, §§ 30,
    31; St. 2018, c. 69, § 57.     When interpreting the meaning of a
    statute, we presume that "as part of familiarizing themselves
    with the subject matter of the legislation, legislators became
    familiar with that pertinent precedent."      See McCarty's Case,
    
    445 Mass. 361
    , 380 (2005).     As the Legislature declined to amend
    intent requirements within the section, we assume that it has
    adopted this construction of the statute.      See Commonwealth v.
    Colturi, 
    448 Mass. 809
    , 812 (2007), citing Nichols v. Vaughan,
    
    217 Mass. 548
    , 551 (1914).
    b.   Meaning of "park" within § 32J.       The defendant also
    contends that the area where the heroin landed when he threw it,
    the walkway, is not a park as the term is used in § 32J.
    Because § 32J does not define "park," we give the term its
    "usual and accepted meaning[]," as long as it is "consistent
    with the statutory purpose."       Commonwealth v. Zone Book, Inc.,
    
    372 Mass. 366
    , 369 (1977).     "We derive the words' usual and
    accepted meanings from sources presumably known to the statute's
    enactors, such as their use in other legal contexts and
    dictionary definitions."     
    Id. The term
    "park" is defined as "a
    tract of land maintained by a city or town as a place of beauty
    26
    or of public recreation."   Webster's Third New International
    Dictionary 1642 (1993).   See Commonwealth v. Campbell, 
    415 Mass. 697
    , 700 (1993), citing Zone Book, 
    Inc., supra
    .   This definition
    is consistent with our use of the term in other legal contexts.
    See Salem v. Attorney Gen., 
    344 Mass. 626
    , 630 (1962) ("as used
    in modern and present times in America the term 'park' usually
    signifies an open or [e]nclosed tract of land set apart for the
    recreation and enjoyment of the public; or, in the general
    acceptance of the term, a public park is said to be a tract of
    land, great or small, dedicated and maintained for the purposes
    of pleasure, exercise, amusement, or ornament; a place to which
    the public at large may resort to for recreation, air, and
    light" [quotation and citation omitted]).   See also G. L. c. 45,
    § 1 ("In this chapter 'park' shall include a city or town common
    dedicated to the use of the public, or appropriated to such use
    without interruption for a period of twenty years").
    Nothing in any of these definitions excludes pedestrian
    walkways, categorically or otherwise.   Nor does the purpose of
    the statute, i.e., to "protect children from the harmful impact
    of drug dealing," 
    Peterson, 476 Mass. at 168
    , suggest the
    exclusion of pedestrian walkways.   See Commonwealth v.
    Mogelinski, 
    466 Mass. 627
    , 633 (2013), citing Wright v.
    Collector & Treas. of Arlington, 
    422 Mass. 455
    , 457-458 (1996)
    (statutory interpretation must be reasonable and supported by
    27
    purpose and history of statute).   Indeed, to the contrary, the
    legislative purpose would be served by a broad definition of
    "park."15
    We conclude that, as a walkway may be considered a "park"
    under § 32J depending upon the circumstances, it is for the jury
    to decide whether a tract of land is publicly owned or
    maintained and dedicated for enjoyment and recreational use by
    the public.   We emphasize that, under this definition, the
    Commonwealth must prove not only that the tract was used by the
    public for recreation, but also that it was dedicated or set
    apart for such use.   See 
    Salem, 344 Mass. at 630
    .    See also
    G. L. c. 45, § 1.   Otherwise, every walkway -- including
    sidewalks, which are primarily intended for transportation
    rather than recreation, see, e.g., 350 Code Mass. Regs. § 5.01
    (2001) (defining "sidewalk" as "[t]hat portion of a roadway or
    parkway . . . set aside for pedestrian travel") -- could
    potentially become a "public park" under § 32J.      A less specific
    definition runs the risk of violating due process.     See
    15The defendant's argument that including pedestrian
    walkways as parks under § 32J would contravene the intent of the
    Legislature is misplaced. As we noted in Commonwealth v.
    Peterson, 
    476 Mass. 163
    , 168-169 (2017), the Legislature
    recognized "the statute's uneven impact on people who live in
    urban areas," and subsequently amended § 32J to reduce the
    school zone radius and to limit the time period in which a
    violation may occur. See St. 2012, c. 192, §§ 30, 31. However,
    the Legislature has not made any changes to the term "park" so
    as to exclude public walkways.

    Commonwealth v. Sefranka, 
    382 Mass. 108
    , 110-111 (1980), and
    cases cited.
    However, we do not require proving the elements of
    dedication for public use as we do in property law.     See, e.g.,
    Longley v. Worcester, 
    304 Mass. 580
    , 588-589 (1939), and cases
    cited ("The owner's acts and declarations should be deliberate,
    unequivocal and decisive, manifesting a clear intention
    permanently to abandon his property to the specific public
    use").    Such proof is unnecessary given that the purpose of
    § 32J is to keep drugs away from certain public spaces, not to
    determine title.    Rather, the Commonwealth may prove that a
    tract is dedicated for public recreational use and enjoyment
    through circumstantial evidence, such as photographs of the
    tract, testimony from those who are involved with maintenance of
    the property, or authoritative maps referring to the tract as a
    "park."    Cf. Commonwealth v. Williams, 
    422 Mass. 111
    , 121 (1996)
    (conviction may be based on circumstantial evidence).
    Conversely, the defense may argue that the tract is used by the
    public for recreational purposes by happenstance rather than the
    intent of the owner.16
    16We note that the jury instructions on the definition of
    "park" were in accordance with our reading of § 32J. The judge
    instructed the jury, "Now, I will tell you that the law . . .
    says the term park usually signifies an open or enclosed tract
    of land set apart for the recreation and enjoyment of the
    public. Or in the general acceptance of the term, a public park
    29
    c.   Motion for a new trial.   Finally, the defendant filed a
    motion for a new trial pursuant to Mass. R. Crim. P. 30 (b), as
    appearing in 
    435 Mass. 1501
    (2001), claiming, as relevant here,
    that his trial counsel failed to challenge adequately the park
    zone charge.   More specifically, the defendant argued that
    because Ely Court, the park named in the indictment, is
    different from the walkway, the area where the defendant tossed
    the drugs, he was convicted of a crime for which he was not
    indicted, and his trial counsel was ineffective in failing to
    raise the issue at any point prior to, or during, the trial.     We
    agree.
    At the evidentiary hearing on the motion for a new trial,
    it was established that Ely Court Park and the walkway are
    distinct, nonadjacent tracts of land separated by a distance of
    more than one hundred feet.   The walkway comprises the last
    third of Ely Street and is perpendicular to Bowers Street.     Ely
    Court Park, on the other hand, sits at the corner of Center
    Street and Lyman Street and contains a basketball court.
    Trial counsel was aware that the distance between where the
    tossed drugs were found and Ely Court Park was greater than one
    hundred feet, and personally observed that the two areas were
    is said to be a tract of land, great or small, dedicated and
    maintained for the purposes of pleasure, exercise, amusement, or
    ornament. A place to which the public at large may resort to
    for recreation, air, and light."
    30
    not contiguous but were instead more than one hundred feet
    apart.     He failed to raise the issue, however, assuming that the
    walkway was nevertheless part of Ely Court Park.    Trial counsel
    further reasoned that, in any case, had he raised the matter by
    way of a motion to dismiss, the Commonwealth likely would have
    moved, and received permission, to amend the indictment to name
    the walkway rather than Ely Court.    Trial counsel believed that
    naming the location of the offense in the indictment was mere
    "surplusage," and unnecessary to describe the crime.    As
    detailed infra, we conclude that trial counsel's strategic
    choices with regard to defending against the § 32J charge were
    manifestly unreasonable.
    First, we disagree with the motion judge that trial counsel
    "reasonably concluded" that the walkway was part of Ely Court
    Park even though the two parcels are not adjacent to one
    another.    Further investigation into the boundaries of Ely Court
    Park would have shown that the walkway was indeed separate;
    according to testimony at the hearing, this information was
    readily available online.
    With a correct understanding of the boundaries of the two
    parcels, trial counsel would have had at least two possible
    options to pursue.    First, he could have moved to dismiss the
    indictment prior to trial.    Even if the Commonwealth had re-
    31
    indicted the defendant to name the correct location,17 counsel
    could have mounted a viable defense to the § 32J charge by
    arguing that the walkway did not meet the definition of a park
    within the meaning of the statute.   See part 
    2.b, supra
    .
    Although the Commonwealth presented evidence that the walkway
    was owned and maintained by the Holyoke parks and recreation
    department, and the photographs of the walkway introduced at
    trial depict a paved walkway surrounded by trees and grass,
    there was no direct evidence on the intended use of the walkway
    -- that is, no testimony or documentation showing that the park
    was dedicated to public recreational use, or even that members
    17Alternatively, an amendment to the indictment in this
    case would have been improper. An indictment may be amended "if
    the amendment is one of form, not substance"; "if the amendment
    will not result in prejudice"; and pursuant to art. 12 of the
    Massachusetts Declaration of Rights, as long as such amendment
    does not "materially change[] the work of the grand jury"
    (quotation and citations omitted). Commonwealth v. Miranda, 
    441 Mass. 783
    , 787 (2004). See Mass. R. Crim. P. 4 (d), 
    378 Mass. 849
    (1979). A motion to amend would have been appropriate if
    the indictment incorrectly referred to the proper parcel by, for
    example, using its former name, or misspelling the name. See
    G. L. c. 277, § 35 (defendant "shall not by acquitted by reason
    of . . . an immaterial mistake in the description of the
    property or the ownership thereof"). See also Commonwealth v.
    Downey, 
    12 Mass. App. Ct. 754
    , 761-762 (1981) (amendment to
    middle initial of third party's name was immaterial and thus not
    in error). Here, because the grand jury handed up an indictment
    for a § 32J violation specifically with respect to Ely Court,
    amending the indictment to indicate a different tract of land
    would have been an amendment of substance rather than one of
    form. See Commonwealth v. Snow, 
    269 Mass. 598
    , 608-610 (1930)
    (although name of victim was not essential element of extortion
    charge, where such person is specifically named in indictment by
    grand jury, amending name is impermissible).
    32
    of the public actually used the walkway for such purposes.
    Trial counsel could have drawn attention by way of cross-
    examination and argument to the aforementioned weaknesses in the
    Commonwealth's evidence.
    Another option would have been for trial counsel to have
    moved for a required finding of not guilty at the close of the
    Commonwealth's case based on the variance between the
    allegations in the indictment and the proof at trial.   As
    
    discussed supra
    , although the indictment names Ely Court as the
    location of the crime, all of the evidence presented pertained
    to the walkway. It is true that "[a] defendant is not to be
    acquitted on the grounds of variance between the allegations and
    proof if the essential elements of the crime are correctly
    stated, unless he is thereby prejudiced in his defence."     G. L.
    c. 277, § 35.   See, e.g., Commonwealth v. O'Connell, 
    432 Mass. 657
    , 660-661 (2000) (no prejudice to defendant where victim is
    not mentioned by name in indictment, but is mentioned by name at
    trial).   However, here, a material element of the crime is that
    the underlying drug offense took place within one hundred feet
    of real property used as a public park or playground.   Although
    there is no real question regarding whether Ely Court Park was a
    park within the meaning of § 32J, as 
    discussed supra
    , the same
    cannot be said for the walkway.   Thus, the fact that the
    location was not correctly identified in the indictment was a
    33
    material inaccuracy.     See Commonwealth v. Barbosa, 
    421 Mass. 547
    , 552-554 (1995) (Commonwealth presented evidence of two drug
    transactions, but ambiguity in indictment as to which
    transaction formed factual basis of charge required reversal of
    convictions).     See also Commonwealth v. Ohanian, 
    373 Mass. 839
    ,
    843 (1977) (conviction of larceny for obtaining money by means
    of checks drawn against insufficient funds reversed where
    indictment incorrectly named bank and defendants had no reason
    to know about sufficiency of funds at named bank).     This is
    especially true where, as here, the indictment naming the wrong
    location was attached to the verdict slip and was sent into the
    jury room during deliberations.     Thus, the jury were asked
    whether the defendant was guilty of possessing drugs within one
    hundred feet of Ely Court, but they heard evidence only about
    the walkway.
    There would have been no downside to challenging the
    variance between the indictment and the evidence.     We conclude
    that trial counsel's failure to do so was manifestly
    unreasonable and deprived the defendant of one or more viable
    defenses.    See Commonwealth v. Acevedo, 
    446 Mass. 435
    , 442
    (2006), citing Commonwealth v. Adams, 
    374 Mass. 722
    , 728 (1978);
    Commonwealth v. Saferian, 
    366 Mass. 89
    , 96 (1974).
    The usual remedy for ineffective assistance of counsel is a
    new trial.     Here, however, counsel was ineffective in failing to
    34
    challenge the sufficiency of the evidence regarding an essential
    element under § 32J -- the proximity of the underlying offense
    to a particular public park.    There was no evidence that the
    defendant's possession of heroin with intent to distribute
    occurred within one hundred feet of Ely Court, the location
    named in the indictment as the public park for the purposes of
    § 32J.    Where an amendment of the indictment at trial to
    identify the correct park would have been improper, see note 
    17, supra
    , and where the Commonwealth presented no evidence at trial
    showing that the defendant committed the underlying drug offense
    within one hundred feet of Ely Court, the evidence was
    insufficient as a matter of law, and the conviction must be
    dismissed with prejudice.    See Commonwealth v. Merry, 
    453 Mass. 653
    , 660 (2009), citing Corson v. Commonwealth, 
    428 Mass. 193
    ,
    201 (1998) ("Where the evidence at the first trial was legally
    insufficient to sustain a verdict, a new trial would violate the
    prohibition against double jeopardy and is therefore
    impermissible").
    Conclusion.    For the reasons 
    stated supra
    , we affirm the
    judgment of conviction of possession with intent to distribute
    heroin.    However, the denial of the defendant's motion for a new
    trial on the § 32J charge is reversed, the judgment of
    conviction on the indictment charging the defendant with the
    35
    § 32J violation is vacated, the jury verdict is set aside, and
    judgment shall enter for the defendant.
    So ordered.
