    APPELLATE DIVISION
    DOCKET NO. A-5556-17T4
    STATE OF NEW JERSEY,
    Plaintiff-Respondent,
    v.
    GREGORY J. HERBERT,
    Defendant-Appellant.
    ___________________________
    Argued October 28, 2020 – Decided December 18, 2020
    Before Judges Sumners and Geiger.
    On appeal from the Superior Court of New Jersey,
    Law Division, Union County, Indictment No. 15-01-
    0065.
    Margaret McLane, Assistant Deputy Public Defender,
    argued the cause for appellant (Joseph E. Krakora,
    Public Defender, attorney; Margaret McLane, of
    counsel and on the briefs).
    Meredith L. Balo, Special Deputy Attorney
    General/Acting Assistant Prosecutor, argued the cause
    for respondent (Lyndsay V. Ruotolo, Acting Union
    County Prosecutor, attorney; Meredith L. Balo, of
    counsel and on the brief).
    PER CURIAM
    Defendant Gregory J. Herbert appeals an October 27, 2016 order that
    granted the State's motion to admit his custodial statement to police in
    evidence at trial, and an October 3, 2017 judgment of conviction and sentence
    for conspiracy to commit first-degree robbery, third-degree possession of a
    weapon for an unlawful purpose, and the lesser-included offenses of fourth-
    degree aggravated assault by pointing a firearm and disorderly persons theft.
    We reverse defendant's convictions and remand for a pretrial hearing and
    retrial.
    We discern the following facts from the evidence presented at the joint
    trial of Herbert and co-defendant Kadeem I. Charles. 1 Herbert, Charles, and
    Michael Onyeagoro met at Charles's house for a party on December 19, 2013.
    Onyeagoro testified at trial that the trio left Charles's shortly after midnight to
    "discuss[] locations or persons that [they could] rob" and eventually decided to
    rob a gas station. 2
    1
    In our separate opinion in the companion appeal filed by Charles, we
    reversed Charles's convictions and remanded for a N.J.R.E. 104 hearing and
    retrial. State v. Charles, No. A-1136-17 (App. Div. Dec. 18, 2020).
    2
    Onyeagoro pled guilty to second-degree conspiracy and turned State's
    witness.
    A-5556-17T4
    2
    The three went forward with the plan.      At approximately 2:30 a.m.,
    Onyeagoro distracted the gas station attendant by driving into the gas station
    and asking for gas. As the attendant pumped gas, Charles pointed a BB gun at
    him while Herbert stole computer equipment. The trio fled the scene.
    Hillside Police Department received a "holdup alarm" from the BP gas
    station on Route 22 at 2:30 a.m. Police found Onyeagoro waiting for Herbert
    and Charles in his car nearby, which matched the description given by the gas
    station attendant. They observed a knife under the seat of the car and arrested
    Onyeagoro for possession of a weapon.
    Information obtained from Onyeagoro led to the arrests of Charles in
    July 2014 and Herbert in August 2014. Police searched Charles's home in
    Irvington and seized two BB guns, a ski mask, a knife, clothing, and gloves.
    Following his arrest in Vermont and return to New Jersey, Herbert was
    interviewed by Hillside Police Detective Sergeant Cosimo Tripoli after Herbert
    was read his Miranda3 rights and waived those rights. Herbert denied being in
    Hillside at the time of the crimes or ever being in Onyeagoro's car.
    After an already lengthy interrogation, police asked defendant: "You
    want to think about some stuff in mind for a few minutes? We'll step out
    3
    Miranda v. Arizona, 
    384 U.S. 436
    (1966).
    A-5556-17T4
    3
    maybe you just want to clear your head and think."          To which defendant
    answered:
    No, I already cleared my head already. If you got the,
    you say you have the evidence, you say you have all
    the answers, then I guess only thing left for you to do I
    guess is go to court and we'll figure it out from there.
    I guess, I get a lawyer and then figure it out from
    there.
    At this point, police did not stop the interview, ask for Herbert to clarify his
    statement, or leave the room. Similarly, Herbert stated, "[y]ou want me to say
    certain things and[] I wish I had the answers for you." Once again, police did
    not stop the interview or seek to clarify Herbert's statement. Herbert repeated
    that he wanted "to leave it up to the court" several more times during the
    interview.
    In addition, police asked Herbert: "Okay. So before we end this today,
    anything else you want to say?"        Herbert responded:     "No, I don't have
    anything."
    In January 2015, a Union County grand jury returned an indictment
    charging Herbert and Charles with the following offenses:                first-degree
    robbery, N.J.S.A. 2C:15-1 (count one); first-degree conspiracy to commit
    robbery, N.J.S.A. 2C:5-2(a)(1) and N.J.S.A. 2C:15-1 (count two); second-
    degree unlawful possession of a weapon, N.J.S.A. 2C:39-5(b) (count three);
    A-5556-17T4
    4
    and third-degree possession of a weapon for an unlawful purpose, N.J.S.A.
    2C:39-4(a)(1) (count four).
    The State moved to admit Herbert's custodial statement at trial. The trial
    court conducted a Miranda hearing on October 25, 2016.
    The court found Herbert to be "calm and cooperative" and "appeared to
    be educated, articulate, and intelligent." During the interview, Herbert was
    questioned for over three hours. The court noted that "while persistent, the
    officers did not raise their voice, threaten Mr. Herbert, or try to trick him."
    The court described Herbert's demeanor as "extremely comfortable" and
    "almost was poised in the interview."
    Based on the "totality of the circumstances, . . . the [c]ourt [found] that
    Herbert knowingly, voluntarily, and intelligently waived his rights and agreed
    to speak to the detectives." It further found Herbert never exercised any of his
    constitutional rights. The court concluded
    that a reasonable and logical interpretation of
    Herbert's comment [that], "[i]f you . . . say you have
    the evidence, you say you have all the answers, then I
    guess only thing left for you to do I guess is to go to
    court and we'll figure it out from there. I guess I get a
    lawyer and then figure it out from there," was simply
    what Herbert was expecting to happen in the future.
    A-5556-17T4
    5
    The court similarly determined that when Herbert described getting a
    lawyer and going to court on several occasions, the reasonable inference is that
    he intended to describe his expectations for the future, not a present invocation
    of the right to counsel.     In addition, the court determined that Herbert's
    statement, "I don't have anything else," is reasonably interpreted as him saying
    he did not have anything more to say about the robbery specifically, not that he
    wanted to terminate the interrogation altogether.      The court explained that
    Herbert could instead have stated, "I'm finished. I want the interview to end."
    However, Herbert did not do so and thus did not actually intend for the
    interview to end. As evidence of his intention to continue the interview, the
    court noted that Herbert proceeded to answer all the of the detectives'
    questions without objection.
    The court stated it was "convinced beyond a reasonable doubt that
    [Herbert] knowingly, voluntarily, and intelligently waived his rights under
    [Miranda] . . . and voluntarily answered all of the detectives' questions without
    ever invoking any of his constitutional rights." Accordingly, the court granted
    the State's motion to introduce portions of Herbert's statement at trial.
    The State proffered Adam Durando as an expert in cellular telephone
    records, cellular mapping programs, and cell-site analysis. The court conducted a
    A-5556-17T4
    6
    N.J.R.E. 104 hearing on the admissibility of Durando's testimony. During the
    hearing, Durando testified that, as part of his job, he makes sure that all Sprint
    customers have cellular service when they attempt make a call. This requires a
    customer's phone to remain in constant contact with a cell tower, which reveals the
    general location of the customer's phone. Durando testified that there may be
    occasion when a cell phone does not connect to the nearest cell-site because a
    different tower might provide a better signal to the customer due to nearby
    buildings, terrain, and local topology. Durando explained, however, that Sprint
    takes into consideration the local terrain, topology of a tower location, and cell-site
    traffic when designing tower sites.
    Durando further testified that he reviewed the cell phone numbers registered
    to Herbert and Charles and used repoll numbers to identify the relevant cell tower
    sites to map the calls at issue in this case. He explained that he reviewed the cell
    phone numbers with Map Info, a commercially accepted mapping tool used
    throughout the industry that graphically represents where Sprint's sites are located
    relative to the streets. Durando testified that although he could not determine the
    exact location of a cell phone during a call, he could confirm that a call was placed
    somewhere within the site's coverage area, which is usually around seven miles.
    Durando also testified that a "drive test" is sometimes performed to cure a
    A-5556-17T4
    7
    customer's complaint about poor service, but he was unable to conduct a drive test
    for this case because he did not have all the information necessary.
    The court granted the State's motion to permit Durando to testify as an
    expert, determining that Durando was highly qualified and "ha[d] sufficient
    expertise" in the fields of cellular telephone records, cellular mapping program,
    and cell-site analysis. It noted that Durando had twenty-five years of experience
    and received forty hours of training annually.
    The court found the State met its burden of proving that Durando's proffered
    testimony was "generally accepted among those in the profession." It pointed to
    case law specifically addressing the reliability and general acceptance of cell-site
    analysis to determine the general location of a cell phone. The court noted that the
    State sought to introduce evidence of defendants' general location based on the use
    of specific cell towers and sectors rather than to pinpoint the exact location of the
    cell phone user. It thus concluded that "[t]estimony concerning the location of cell
    towers, the sectors used for each call, and the general location" of cell phones
    when connected to each tower "[a]re the product of reliable principles and
    methods." Lastly, the court concluded that "[a]ny questions concerning the
    mapping data and the reliability of testimony" affect "the weight of his testimony,"
    not its admissibility.
    A-5556-17T4
    8
    The trial commenced on June 6, 2017. We briefly recount the pertinent
    testimony, objections, and evidentiary rulings made by the trial court. We also
    discuss the accomplice liability instruction given by the court.
    The State called Onyeagoro to testify about the content and background
    of text messages between Onyeagoro, Charles, and Herbert on the night of the
    robbery.   The first text message was from Onyeagoro to Charles; it read:
    "Text me this n--ga Herbert['s] number[.]" Charles replied, "Ight[.]"
    Onyeagoro testified that he texted Herbert to "[contact him] back [about]
    that ish we'd talked about its still in the office[.]" He explained that when he
    referred to the office, he meant "the safe that is in the office at [his] job."
    Onyeagoro explained that another text message to Herbert, which read: "All
    right. Nothing crazy. A quick grab and go[,]" meant "a quick in and out"
    robbery of the office where Onyeagoro worked. He testified that the text
    message referred to a planned robbery.
    The State introduced text messages between Onyeagoro and Herbert's
    cell phones.   Both defense counsel objected to the admission of the text
    messages, claiming lack of authentication based on the impossibility of
    knowing whether Herbert personally sent the messages even though they were
    sent to or from his cell phone. The court overruled the objection, finding that
    A-5556-17T4
    9
    Herbert's argument went to the weight of the evidence, not its admissibility.
    Defense counsel did not, however, object to the contents of the messages due
    to their reference to prior bad acts and resulting prejudicial impact.
    Soon thereafter, Onyeagoro testified that he, Herbert, and Charles
    attended a party that night, and after the party, he drove the trio around and
    were "not particularly doing anything. [They] were just discussing locations
    or persons that [they could] rob." Charles suggested they rob the BP station on
    Route 22. Onyeagoro testified that at first he refused "because it was getting
    late but [Charles and Herbert] insisted because the profit of that previous night
    into the morning was low." This was appeared to be a reference to another
    robbery the three had committed.
    Both defense attorneys objected and moved for a mistrial because
    Onyeagoro was implicating both defendants in other crimes. The court denied
    the motion for a mistrial but sustained the objection since the testimony
    implied that defendants committed other, uncharged crimes.          It found that
    although Onyeagoro's statement began to implicate defendants of a different
    crime, his testimony could be interpreted in other ways and thus did not
    warrant a mistrial. The court struck Onyeagoro's statement and directed the
    jury to "disregard it and not to consider it as evidence in this case" but did not
    A-5556-17T4
    10
    provide further instruction to avoid shedding more light on the substance of
    the testimony. Defense counsel agreed.
    According to Onyeagoro, during the robbery of the gas station, Charles
    had a gun and Herbert had a knife. Onyeagoro pulled up to a pump and asked
    for $20 worth of gas. Charles put the attendant in a choke hold and placed the
    gun at his head. Charles or Herbert shouted, "give us the f--king money,
    where is the f--king money at." Onyeagoro identified Charles and Herbert as
    the men in the surveillance video. Herbert told Onyeagoro to leave; he pulled
    away from the gas station without his gas cap. Onyeagoro was stopped by
    police shortly thereafter.
    During cross-examination, defendants attacked Onyeagoro's credibility
    by demonstrating that in several instances, his testimony on direct materially
    varied from what he told the police during the investigation.      Defendants
    attempted to show that Onyeagoro implicated Charles and Herbert in order to
    obtain a favorable plea agreement that reduced his exposure from first -degree
    to second-degree robbery and resulted in a downgraded three-year prison term.
    The State also presented Durando's expert cell-site analysis testimony.
    Durando testified that he used the defendants' phone numbers and cell-site data
    to map out the location of the defendants' phones at the time of the robbery.
    A-5556-17T4
    11
    Further, Durando testified that defendants' phones were within seven miles of
    the cell tower they connected to.
    The State also presented New Jersey State Police Detective Sergeant
    First Class Brett Bloom, who is assigned to the Firearms Investigation Unit as
    a firearms expert. The gun in evidence was a BB gun pistol. He testified
    without objection that neither Chares nor Herbert had ever been issued a
    permit to carry a handgun, a permit to purchase a handgun, a firearm
    identification card, or a permit for an assault weapon in the State of New
    Jersey.   He further testified that that under New Jersey law, a BB gun is
    considered a firearm and is subject to the same permitting procedures.
    At the close of the State's case, defendants moved for judgment of
    acquittal on the unlawful possession of a firearm count based on the lack of
    evidence that the BB gun was operable. The court granted the motion, noting
    "the State has not called an expert in regard to operability." It explained t hat
    N.J.S.A. 2C:39-5(b) requires the State to prove that the firearm at issue was
    "originally designed or manufactured to fire or eject any solid projectile[ or]
    ball[.]" Because the State did not call an expert regarding operability, the
    court found the "jury would have to speculate" about whether the BB gun "was
    originally designed or manufactured to eject" a projectile ball.
    A-5556-17T4
    12
    On the other hand, the court held that a BB gun is a firearm under
    N.J.S.A. 2C:39-4(a) because operability is not an element of possession of a
    firearm for an unlawful purpose. Neither defense counsel argued for judgment
    of acquittal of the aggravated assault by pointing a firearm charge.
    During its summation, the State discussed Durando's expert testimony.
    The State argued that, according to Durando's testimony, defendants were in
    the general area of the crime and that they were together.
    The court instructed the jury on accomplice liability with respect to the
    robbery count and lesser-included theft charge but not as to the aggravated
    assault by pointing a firearm charge. Neither defense counsel objected.
    On June 29, 2017, the jury acquitted Herbert and Charles of robbery but
    found both guilty of the lesser-included offenses of fourth-degree aggravated
    assault by pointing a firearm and disorderly persons theft; second-degree
    conspiracy to commit robbery; and second-degree possession of a weapon for
    an unlawful purpose.
    At sentencing, the State argued for consecutive terms. Applying the
    Yarbough4 factors, the court declined to impose any consecutive terms.
    4
    State v. Yarbough, 
    100 N.J. 627
    (1985).
    A-5556-17T4
    13
    Defense counsel argued that Herbert should be sentenced in the third-
    degree range on the two second-degree crimes, contending the mitigating
    factors substantially outweighed the limited aggravating factors.     Counsel
    noted that Onyeagoro was sentenced to a downgraded three-year term on the
    second-degree conspiracy count that he pleaded guilty to.
    The court found aggravating factor nine (need for deterrence), N.J.S.A.
    2C:44-1(a)(9), outweighed mitigating factor seven ("no history of prior
    delinquency or criminal activity"), N.J.S.A. 2C:44-1(b)(7). The court rejected
    mitigating factor six (defendant has or will compensate the victim), N.J.S.A.
    2C:44-1(b)(6), because the victim returned to the country from which he
    immigrated from and has not been compensated. It rejected mitigating factor
    eight (defendant's conduct was the result of circumstances unlikely to recur),
    N.J.S.A. 2C:44-1(b)(8), finding Herbert was equally culpable of the crimes
    despite defendant's assertion that Onyeagoro was the true mastermind. The
    court rejected mitigating factor nine (the character and attitude of the
    defendant indicate he is unlikely to reoffend), N.J.S.A. 2C:44-1(b)(9), because
    there was insufficient evidence to make that finding.
    Following merger of the aggravated assault by pointing a firearm count
    into count four, Herbert was sentenced to an aggregate seven-year term. More
    A-5556-17T4
    14
    specifically, Herbert received a six-month term for the disorderly persons
    theft; a seven-year term, subject to the mandatory periods of parole
    ineligibility and parole supervision under the No Early Release Act (NERA),
    N.J.S.A. 2C:43-7.2, for the conspiracy to commit robbery; and a seven-year
    term, subject to a forty-two-month period of parole ineligibility pursuant to the
    Graves Act, N.J.S.A. 2C:43-6(c), for the possession of a weapon for an
    unlawful purpose. All terms run concurrently. This appeal followed.
    Herbert raises the following points for our consideration.
    POINT I
    THE TRIAL COURT ERRED IN ADMITTING
    HERBERT'S STATEMENT TO POLICE BECAUSE
    HE INVOKED HIS RIGHTS TO SILENCE AND TO
    COUNSEL.
    POINT II
    DEFENDANT'S   CONVICTIONS    MUST   BE
    REVERSED DUE TO THE IMPROPER ADMISSION
    OF TESTIMONY ABOUT OTHER UNCHARGED
    ROBBERIES.
    POINT III
    THE TRIAL COURT ERRED IN ADMITTING
    ENTIRELY IRRELEVANT EXPERT TESTIMONY
    AND MAPS ABOUT CELL SITE DATA, AND THE
    PROSECUTOR COMMITTED MISCONDUCT BY
    MISCHARACTERIZING THE TESTIMONY.
    A-5556-17T4
    15
    A. Introduction.
    B. The Expert Testimony And Maps Were
    Inadmissible Because They Were Irrelevant But
    Highly Prejudicial.
    C. The State's Use Of The Expert Testimony
    And Maps Was Inappropriate And Prejudicial.
    POINT IV
    THE FAILURE TO INSTRUCT THE JURY ON
    ACCOMPLICE    LIABILITY   FOR   THE
    AGGRAVATED ASSAULT CHARGE REQUIRES
    ITS REVERSAL.
    POINT V
    DEFENDANT'S        SENTENCE       IS   MANIFESTLY
    EXCESSIVE.
    POINT VI
    THE TRIAL COURT ERRED BY REFUSING TO
    DISMISS THE COUNTS CHARGING POSSESSION
    OF A FIREARM FOR AN UNLAWFUL PURPOSE
    AND AGGRAVATED ASSAULT BY POINTING A
    FIREARM. (Not Raised Below).
    I.
    Herbert contends that the trial court erred in admitting his statement to
    police because he repeatedly invoked his right to remain silent and to counsel,
    but police continued interrogating him. He argues that although he denied any
    involvement in the gas station robbery, "portions of his statement undermined
    A-5556-17T4
    16
    his credibility and thus gave the jury an impermissible reason to credit
    Onyeagoro's trial testimony." 5 We disagree.
    We are guided by well-established legal principles. When reviewing "a
    trial court's admission of police-obtained statements," we "engage in a
    'searching and critical' review of the record to ensure protection of a
    defendant's constitutional rights." State v. Maltese, 
    222 N.J. 525
    , 543 (2015)
    (quoting State v. Hreha, 
    217 N.J. 368
    , 381-82 (2014)).              "We do not
    independently assess evidence as if we are the trial court."
    Ibid. (citing Hreha, 217
    N.J. at 382). Rather, we "typically defer to the trial court's credibility and
    factual findings." 
    Hreha, 217 N.J. at 382
    . Such "findings should be disturbed
    only if they are so clearly mistaken 'that the interests of justice demand
    intervention and correction.'"    State v. Tillery, 
    238 N.J. 293
    , 314 (2019)
    (quoting State v. A.M., 
    237 N.J. 384
    , 395 (2019)). "However, we owe no
    deference to conclusions of law made by lower courts in suppression
    decisions, which we instead review de novo." State v. Boone, 
    232 N.J. 417
    ,
    426 (2017) (citing State v. Watts, 
    223 N.J. 503
    , 516 (2015)).
    5
    Defendant argues that a statement taken from the interview, in which he
    denied that a phone number was his, was used at trial to undermine his
    credibility.
    A-5556-17T4
    17
    Evidence obtained in violation of Miranda must be suppressed at trial.
    State v. Hartley, 
    103 N.J. 252
    , 262 (1986). Herbert does not argue that the
    Miranda warnings he received were somehow defective. Nor does he argue
    that he did not initially waive those rights "voluntarily, knowingly and
    intelligently." 
    Miranda, 384 U.S. at 444
    ; 
    Hartley, 103 N.J. at 261
    . Instead, he
    argues he exercised his right to remain silent.
    Whether a defendant invoked the right to remain silent is determined
    under the totality of the circumstances.          
    Maltese, 222 N.J. at 545
    .     An
    invocation of the right to remain silent must be "scrupulously honored."
    
    Hartley, 103 N.J. at 255-56
    (citing Michigan v. Mosley, 
    423 U.S. 96
    (1975)).
    If the invocation is ambiguous, the officer may only ask clarifying questions
    about whether he or she meant to invoke the right to remain silent. State v.
    Johnson, 
    120 N.J. 263
    , 283 (1990). An ambiguous invocation of the right to
    remain silent must be clarified before authorities can proceed to question a
    suspect. State v. S.S., 
    229 N.J. 360
    , 384, 386 (2017).
    Where the totality of the circumstances demonstrates that the defendant
    exercised his right to remain silent or to counsel, whether ambiguously or
    unambiguously, the Hartley bright-line rule requires Miranda warnings to be
    readministered. 
    Hartley, 103 N.J. at 267
    .
    A-5556-17T4
    18
    Applying these principles, we discern no error.         The record fully
    supports the court's findings that Herbert "knowingly, voluntarily, and
    intelligently waived his rights and agreed to speak to the detectives" and did
    not subsequently exercise his right to remain silent or to speak to an attorney
    or to have counsel present.      The record further supports the trial court's
    findings that Herbert's comments about getting a lawyer and going to court
    related to "what Herbert was expecting to happen in the future," "not an
    invocation of the right to an attorney."
    The record likewise supports the trial court's finding that a reasonable
    interpretation of Herbert's comment, "No.      I don't have anything else[,]"
    merely expressed that he did not have anything more to say about the robbery,
    not that he wanted to terminate the interview entirely. The record further
    supports its finding that Herbert did not say anything else that "could [be]
    reasonably interpret[ed] as wanting to terminate the interview."
    The court found that Herbert, who "remained calm, cool, and collected
    throughout the interview" and appeared to be "educated, articulate, and
    intelligent," could easily have said that he wanted the interview to end but did
    not do so. He also never told the detectives that he wanted to speak to an
    attorney or to have one present.      Instead, "throughout the interview . . .
    A-5556-17T4
    19
    defendant . . . answered all of the detectives' questions, disagreed with their
    accusation, and more than held his own."        Moreover, "[a]t no time did he
    appear reluctant to answer their questions or to be uncomfortable. In fact,
    Herbert appeared . . . to be quite relaxed and at eas[e], comfortable and
    confident during the entire interview and was rather talkative at times. "
    Considering the totality of the circumstances, the trial court properly
    determined that Herbert's statement was admissible in evidence. Moreover,
    the ultimate use of Herbert's denial that a certain phone number was his to
    undermine his credibility, "was harmless [error] beyond a reasonable doubt."
    
    Tillery, 238 N.J. at 319
    .    This evidence did "little to advance the State's
    otherwise comprehensive case against defendant."
    Id. at 322. II.
    We next address Herbert's argument that the trial court erred by
    admitting Onyeagoro's testimony and text messages from December 19 about
    other uncharged robberies without a limiting instruction. We agree.
    Generally, "evidence of other crimes, wrongs, or acts is not admissible
    to prove a person's disposition in order to show that on a particular occasion
    the person acted in conformity with such disposition." N.J.R.E. 404(b)(1).
    Accordingly, "[e]vidence regarding other specific acts may not be used to
    A-5556-17T4
    20
    prove the commission of a particular act on a particular occasion, unless they
    establish habit or routine practice under N.J.R.E. 406." Biunno, Weissbard &
    Zegas, Current N.J. Rules of Evidence, cmt. 1(b) on N.J.R.E. 404 (2020).
    Evidence of other crimes and bad acts "may be admitted for other
    purposes, such as proof of motive, opportunity, intent, preparation, plan,
    knowledge, identity, or absence of mistake or accident when such matters are
    relevant to a material issue in dispute." N.J.R.E. 404(b)(2). Thus, evidence of
    a prior bad act may be admissible to establish a "common scheme or plan, a
    signature crime, motive, and most frequently, to impeach the accused who
    takes the witness stand, but only through a conviction." State v. Weeks, 
    107 N.J. 396
    , 406-07 (1987).
    Rule 404(b) is based on "the inordinate prejudice to the defendant
    inherent in other-crimes evidence." State v. Hernandez, 
    334 N.J. Super. 264
    ,
    269 (App. Div. 2000), aff'd as mod., 
    170 N.J. 106
    (2001). "The underlying
    danger of admitting other-crime evidence is that the jury may convict the
    defendant because he is 'a "bad person" in general.'" State v. Cofield, 
    127 N.J. 328
    , 336 (1992) (quoting State v. Gibbons, 
    105 N.J. 67
    , 77 (1987)).
    Even where other bad acts are used for an admissible purpose, trial
    courts should "take pains to instruct juries carefully and comprehensively, with
    A-5556-17T4
    21
    ample reference to the specific evidence and issues in a case, on the limited
    relevance of other [bad act] evidence." State v. Stevens, 
    115 N.J. 289
    , 309
    (1989). The trial court must provide a limiting instruction to the jury "both
    when the evidence is first presented and again as part of the final jury charge."
    State v. Garrison, 
    228 N.J. 182
    , 200 (2017) (quoting State v. Rose, 
    206 N.J. 141
    , 161 (2011)).
    Before a court determines whether a prior bad act is admissible for a
    particular purpose, it should determine first whether the evidence relates to a
    prior bad act or whether it is intrinsic to the charged offense.        State v.
    Brockington, 
    439 N.J. Super. 311
    , 325 (App. Div. 2015) (quoting 
    Rose, 206 N.J. at 179
    ). Evidence that is intrinsic to a crime, while needing to satisfy the
    rules relating to relevancy and undue prejudice, "is exempt from the strictures
    of Rule 404(b)." 
    Rose, 206 N.J. at 177-78
    .
    Intrinsic evidence is limited to two categories:        (1) evidence that
    "directly proves" the charged offense; and (2) evidence that, when "performed
    contemporaneously with the charged crime," facilitates "the commission of the
    charged crime." 
    Brockington, 439 N.J. Super. at 327-28
    (quoting 
    Rose, 2016 N.J. at 180
    ). As to the second category of intrinsic evidence, the temporal
    proximity between the uncharged bad act and the indicted crime must be
    A-5556-17T4
    22
    contemporaneous, not simply "close in time[,]" and the link between the same
    must be "meaningful." 
    Brockington, 439 N.J. Super. at 338
    .
    Because Herbert did not raise issue to the testimony or use of the text
    messages under Rule 404(b), he must show that the court's admission of the
    evidence was "plain error clearly capable of producing an unjust result." State
    v. Bunch, 
    180 N.J. 534
    , 541 (2004) (quoting State v. Afanador, 
    151 N.J. 41
    , 54
    (1997)); R. 2:10-2.
    Herbert asserts that the court's admission of the text messages that
    implicated defendant in a "quick grab and go" and Onyeagoro's explanation
    constituted plain error as a prior uncharged crime in violation of N.J.R.E.
    404(b). Herbert further asserts that even if the text messages were admissible,
    the trial court was required to provide a limiting instruction to the jury.
    The State asserts the text messages were intrinsic evidence not within
    the scope of Rule 404(b) because they directly prove the commission of the
    conspiracy to commit robbery and the eventual robbery of the gas station for
    which defendant was on trial. We disagree.
    The admission of the text messages is precisely the situation where a
    limiting instruction is necessary to ensure that the jury does not misapply this
    highly prejudicial evidence. To be sure, the text message conversation, which
    A-5556-17T4
    23
    shows an agreement to steal from the safe at Onyeagoro's workplace, is strong
    evidence of a conspiracy to commit a theft at that location.        Herbert and
    Onyeagoro discussed a quick "grab and go" theft at Onyeagoro's workplace
    after Onyeagoro got off work.       However, neither Herbert nor Onyeagoro
    mentioned the use of force or use of threats to accomplish the theft, which are
    essential elements to a conspiracy to commit robbery. See N.J.S.A. 2C:15-1
    and N.J.S.A. 2C:5-2.
    More fundamentally, the text messages did not discuss plans to rob the
    gas station. They are extrinsic to Herbert's charges. Accordingly, the trial
    court was required to conduct a Rule 404(b) analysis but did not do so. The
    court should have analyzed whether the text messages could be used to show a
    common plan or motive to prove a robbery, unlawful possession of a firearm,
    or possession of a firearm for unlawful purposes.        In any event, even if
    admissible under Rule 404(b), the trial court would have needed to provide the
    jury with a limiting instruction. See 
    Stevens, 115 N.J. at 309
    (explaining that
    trial courts should "take pains to instruct juries carefully and comprehensively,
    with ample reference to the specific evidence and issues in the case, on the
    limited relevance of other[ bad act] evidence").
    A-5556-17T4
    24
    First, evidence relating to an agreement to make a quick "grab and go"
    did not "directly prove" the crime of robbery, which has more elements than
    the crime contemplated in the text messages. The text messages also did not
    facilitate the commission of the gas station robbery. While the jury eventually
    found defendant not guilty of robbery, the text message evidence may well
    have been used in the jury's deliberation in considering whether to convict
    Herbert of the lesser-included offenses "because he is a bad person in general."
    
    Cofield, 127 N.J. at 336
    (quotations omitted).
    In addition, the text messages did not directly prove or facilitate the
    commission of the crimes of unlawful possession of weapons or possession of
    weapons for unlawful purposes. N.J.S.A. 2C:39-4(a)(1) and N.J.S.A. 2C:39-
    5(b). While the trial court eventually dismissed the unlawful possession of a
    weapon charge, the jury found defendant guilty of possession of a weapon for
    an unlawful purpose. The jury may well have impermissibly used the highly
    prejudicial text messages as evidence that Herbert was likely to commit this
    crime.
    Our Supreme Court has determined that a Rule 404(b) violation
    necessitates reversal if the limiting instruction is inadequate. See 
    Cofield, 127 N.J. at 341-42
    (ordering a reversal where the limiting instruction "did not
    A-5556-17T4
    25
    narrowly focus the jury's attention on the specific use of other[ bad act]
    evidence, but instead made reference only to the generalities of [Rule
    404(b)].").   But see 
    Stevens, 115 N.J. at 309
    (concluding reversal is not
    necessary where the trial court twice cautioned the jury against using 404(b)
    evidence as propensity evidence).     Here, the trial court's failure to give a
    limiting instruction was "plain error clearly capable of producing an unjust
    result."   
    Bunch, 180 N.J. at 541
    (quoting 
    Afanador, 151 N.J. at 54
    ).
    Accordingly, we reverse Herbert's convictions for aggravated assault by
    pointing a firearm, theft, and possession of a firearm for an unlawful purpose.
    In addition, we also reverse Herbert's conviction for conspiracy to
    commit robbery.     The text messages were not admissible to prove the
    conspiracy to commit the robbery at the gas station.        Combined with the
    possible prejudice implicated from Onyeagoro's statement about the low
    profits the night before, which was stricken but not cured, we conclude that the
    admission of the text messages also constituted plain error infecting the
    conviction for conspiracy.
    On remand, Herbert shall be retried after conducting a Rule 404(b)
    analysis. If deemed admissible as to the charges other than conspiracy to
    commit robbery, an appropriate limiting instruction shall be given to the jury.
    A-5556-17T4
    26
    III.
    Herbert argues that the trial court erred in admitting expert testimony
    and maps about cell-site analysis that was not sufficiently reliable and
    irrelevant,   and     that   the   prosecutor   engaged   in   misconduct     by
    mischaracterizing that testimony.
    A.
    We first address whether the expert testimony was sufficiently reliable to
    be admissible.      A trial court's evidentiary determination that a witness is
    qualified to present expert testimony under N.J.R.E. 702 is reviewed for abuse
    of discretion "and will only be reversed for manifest error and injustice." State
    v. Rosales, 
    202 N.J. 549
    , 562-63 (2010) (quoting State v. Jenewicz, 
    193 N.J. 440
    , 455 (2008)). N.J.R.E. 702 provides: "If scientific, technical, or other
    specialized knowledge will assist the trier of fact to understand the evidence or
    to determine a fact in issue, a witness qualified as an expert by knowledge,
    skill, experience, training, or education may testify thereto in the form of an
    opinion or otherwise."
    The party offering the expert testimony bears the burden of proof. State
    v. Harvey, 
    151 N.J. 117
    , 167 (1997) (citing Windmere, Inc. v. Int'l Ins. Co.,
    A-5556-17T4
    27
    
    105 N.J. 373
    , 378 (1987)). Our Supreme Court has set out a three-part test for
    the admission of expert testimony:
    (1) the intended testimony must concern a subject
    matter that is beyond the ken of the average juror; (2)
    the field testified to must be at a state of the art such
    that an expert's testimony could be sufficiently
    reliable; and (3) the witness must have sufficient
    expertise to offer the intended testimony.
    
    [Jenewicz, 193 N.J. at 454
    .]
    Herbert essentially contests only the second prong under Jenewicz, that
    the cell-site tower analysis was not sufficiently reliable.       He asserts that
    Durando's testimony—that Herbert's cell phone was within a particular area
    around the time of the crime—required a "drive test" because, as Durando
    testified, cell-site information can only give a rough estimation of Herbert's
    location. The State relies on Frye v. United States, 
    293 F. 1013
    , 1014 (D.C.
    Cir. 1923), for the proposition that it satisfied the second prong because cell -
    site tests have gained "general acceptance in the particular field."
    The test for admissibility in criminal cases is "whether the scientific
    community generally accepts the evidence." 
    Harvey, 151 N.J. at 170
    (citing
    State v. Spann, 
    130 N.J. 484
    , 509 (1993); 
    Windmere, 105 N.J. at 386
    ).
    "General acceptance, however, does not require complete agreement over the
    accuracy of the test or the exclusion of the possibility of error."
    Id. at 171.
    To
    A-5556-17T4
    28
    establish general acceptance, "the party proffering the evidence need not show
    infallibility of the technique nor unanimity of its acceptance in the scientific
    community." State v. Cassidy, 
    235 N.J. 482
    , 492 (2018). Here, the State must
    prove that the cell-site analysis methodology "and the interpretation of its
    results are non-experimental, demonstrable techniques that the relevant
    scientific community widely, but perhaps not unanimously, accepts as
    reliable." 
    Harvey, 151 N.J. at 171
    .
    "Whether expert testimony is sufficiently reliable to be admissible under
    N.J.R.E. 702 is a legal question we review de novo." State v. J.L.G., 
    234 N.J. 265
    , 301 (2018). "When reviewing a decision on the admission of scientific
    evidence, an appellate court should scrutinize the record and independently
    review the relevant authorities, including judicial opinions and scientific
    literature." 
    Harvey, 151 N.J. at 167
    .
    The trial court relied on United States v. Jones, 
    918 F. Supp. 2d 1
    (D.D.C. 2013), which recognized the reliability of cell-site analysis to
    determine the relative location of a cell phone at a particular time. Notably,
    defendant does not assert that there is controlling case law that finds cell -site
    analysis unreliable or otherwise inadmissible.        Instead, defendant argues
    simply that cell-site data is not the most helpful information.
    A-5556-17T4
    29
    Having carefully reviewed the record in light of the applicable
    precedents, we affirm the trial court's conclusion that historical cell-site data
    analysis is generally accepted in the scientific community and sufficiently
    reliable to be admitted into evidence to show the general location of a cell
    phone at a particular time. The trial court properly found that cell-site analysis
    is a sufficiently reliable method to determine the approximate location of a cell
    phone at the time an incident occurred.
    There is no published opinion in this State squarely addressing the
    admissibility of historical cell-site data analysis in a criminal matter, but a
    number of out-of-state and federal precedents, however, are instructive.
    Federal courts have been receptive to expert testimony regarding
    historical cell-site data analysis. "District courts that have been called upon to
    decide whether to admit historical cell-site analysis have almost universally
    done so." United States v. Hill, 
    818 F.3d 289
    , 297 (7th Cir. 2016); see United
    States v. Weathers, 
    169 F.3d 336
    , 339 (6th Cir. 1999) (discussing admission of
    expert testimony on historical cell-site data analysis); United States v.
    Reynolds, 626 Fed. App'x 610, 618 (6th Cir. 2015) 6 (allowing historical cell
    6
    We cite these cases for sake of completeness, noting that although the cases
    are reported in the Federal Appendix, they are not published and, therefore, do
    not constitute precedent. R. 1:36-3. We note, however, that Rule 32.1 of the
    A-5556-17T4
    30
    site data analysis to show where parties other than defendant were not); United
    States v. Schaffer, 
    439 F. App'x 344
    , 347 (5th Cir. 2011) (concluding that the
    field   of   historical   cell-site   data    analysis   "is   neither   untested    nor
    unestablished"); 
    Jones, 918 F. Supp. 2d at 5
    (finding "the use of cell phone
    location records to determine the general location of a cell phone" to be both
    widely accepted and "based on reliable methodology"); United States v. Evans,
    
    892 F. Supp. 2d 949
    , 955-56 (N.D. Ill. 2012) (finding "granulization theory" to
    be unreliable science, but still finding other historical cell site data analysis
    methods have been adequately tested).
    So too have the courts of other States. See State v. Johnson, 
    797 S.E.2d 557
    , 563 (W.Va. 2017); Pullin v. State, 
    534 S.E.2d 69
    , 71 (Ga. 2000); Wilson
    v. State, 
    195 S.W.3d 193
    , 200-02 (Tex. Crim. App. 2006) (allowing a Sprint
    employee to testify as an expert on historical cell site data analysis).
    In Hill, the Seventh Circuit found that "[h]istorical cell-site analysis can
    show with sufficient reliability that a phone was in a general area, especially in
    a well-populated one. It shows the cell sites with which the person's cell
    phone connected, and the science is well 
    understood." 818 F.3d at 298
    (citing
    
    Evans, 892 F. Supp. 2d at 956
    ).
    Federal Rules of Appellate Procedure permits citation to opinions reported in
    the Federal Appendix.
    A-5556-17T4
    31
    An expert may rely on any "sufficiently reliable" test; the test need not
    be the most accurate.
    Ibid. Because cell-site data
    is sufficiently reliable and
    may indicate the general whereabouts of a person's cell phone, the trial court
    properly admitted Durando's testimony.
    B.
    We next address whether the cell-site analysis was irrelevant. "'Relevant
    evidence' means evidence having a tendency in reason to prove or disprove
    any fact of consequence to the determination of the action." N.J.R.E. 401. An
    explanation of how cell towers work and the general location of Herbert's cell
    phone on the night of the incident would be helpful to the jury in
    understanding the State's claims about the movements and whereabouts of
    Herbert and his co-conspirators. The cell-site analysis would allow the jury to
    narrow the possible location of Herbert's cell phone during the course of the
    conspiracy. Accordingly, it was relevant.
    C.
    Defendant further contends the prosecutor committed misconduct by
    mischaracterizing the cell-site analysis testimony and evidence during
    summation. We disagree.
    A-5556-17T4
    32
    "[A] prosecutor is afforded considerable leeway to make forceful
    arguments in summation." State v. Bradshaw, 
    195 N.J. 493
    , 510 (2008) (citing
    Bender v. Adelson, 
    187 N.J. 411
    , 431 (2006)).          "Indeed, prosecutors in
    criminal cases are expected to make vigorous and forceful closing arguments
    to juries." State v. Frost, 
    158 N.J. 76
    , 82 (1999) (citing State v. Harris, 
    141 N.J. 525
    , 559 (1995)). "Nevertheless, a prosecutor's summation 'is limited to
    commenting upon the evidence and reasonable inferences to be drawn
    therefrom.'"   State v. Feaster, 
    156 N.J. 1
    , 58-59 (1998) (quoting State v.
    Johnson, 
    120 N.J. 262
    , 296 (1990)). A prosecutor "should [neither] make
    inaccurate legal or factual assertions during a trial," 
    Bradshaw, 195 N.J. at 510
    (quoting 
    Frost, 158 N.J. at 85
    ), nor make "references to matters extraneous to
    the evidence," State v. Jackson, 
    211 N.J. 394
    , 408 (2012). Mischaracterizing
    evidence is similarly improper. See 
    Frost, 158 N.J. at 85
    (concluding "the
    prosecutor's comments were not only inaccurate, they were misleading as
    well").
    That said, prosecutorial "misconduct does not warrant reversal unless it
    is 'so egregious that it deprived the defendant of a fair trial.'" 
    Jackson, 211 N.J. at 409
    (quoting 
    Frost, 158 N.J. at 83
    ).      "Prosecutorial comments are
    deemed to have violated the defendant's right to a fair trial when they 'so
    A-5556-17T4
    33
    infect[] the trial with unfairness as to make the resulting conviction a denial of
    due process.'"
    Ibid. (alteration in original)
    (quoting State v. Koedatich, 
    112 N.J. 225
    , 338 (1988)).
    During summation, the prosecutor stated, in relevant part:
    It's been clear what it is and what it is not. This
    is not GPS location data. This is not going to tell you
    the cross street somebody is sitting at, the house
    they're in. It is a tool that's twofold. Those twofold
    tools are for the first purpose being general area.
    Where are these people -- where is this phone
    generally located.
    ....
    Between the hours of then 10 p.m. and 10:49
    p.m. both Gregory Herbert and Kadeem Charles' cell
    phones are pinging off the towers . . . right in
    Irvington. We know where their cell phones are
    located and the State submits to you where these two
    men are located at 10:50, they're together.
    ....
    Now, between 2:34 and 2:37 a.m. we have cell phones
    hitting down in Hillside.
    These statements were, for the most part, well within the wide latitude
    afforded a prosecutor during his summation. See State v. DiFrisco, 
    137 N.J. 434
    , 474 (1994). The statement that the cell-site data could not give a precise
    GPS-like location was accurate. The statement that we knew the cell phone
    A-5556-17T4
    34
    was first in Irvington and then in Hillside is likewise accurate according to
    Durando's testimony.      But the statement that the defendants were together
    because their cell phones connected to the same towers for hours on the night
    of the crime went beyond a natural inference drawn from the evidence. At
    most, one could reasonably infer defendants were in the same vicinity during
    the period in question.
    With that singular exception, we hold that the prosecutor did not unfairly
    or inaccurately characterize the expert's testimony, much less engage in any
    misconduct that deprived defendant of a fair trial. On retrial, the prosecutor
    shall not argue that the cell-site analysis demonstrated that defendants were
    together.
    IV.
    We next address Herbert's argument that the trial court erred by failing
    to instruct the jury on accomplice liability regarding the aggravated assault by
    pointing a firearm charge. We agree.
    "Accurate and understandable jury instructions in criminal cases are
    essential to a defendant's right to a fair trial." State v. Concepcion, 
    111 N.J. 373
    , 379 (1988). "A charge is a road map to guide the jury, and without an
    appropriate charge a jury can take a wrong turn in its deliberations. Thus, the
    A-5556-17T4
    35
    court must explain the controlling legal principles and the questions the jury is
    to decide."    State v. Martin, 
    119 N.J. 2
    , 15 (1990).         "Erroneous jury
    instructions on matters material to a jury's deliberations are ordinarily
    presumed to be reversible error." State v. Jackmon, 
    305 N.J. Super. 274
    , 277-
    78 (App. Div. 1997).
    Where defense counsel does not object to a jury instruction at trial, the
    reviewing court will review it for plain error. R. 2:10-2. An erroneous jury
    instruction is plain error where the "possibility of injustice is 'sufficient to
    raise a reasonable doubt as to whether the error led the jury to a result it
    otherwise might not have reached.'" State v. Hogan, 
    297 N.J. Super. 7
    , 21
    (App. Div. 1997) (quoting State v. Macon, 
    57 N.J. 325
    , 336 (1971)).
    Importantly, a trial court's failure to instruct the jury on accomplice
    liability with respect to a lesser-included offense is plain error where
    "reasonable persons could differ in their perceptions concerning [the
    defendant's] exact role and level of participation in the criminal events." State
    v. Harrington, 
    310 N.J. Super. 272
    , 278-80 (App. Div. 1998). See also State v.
    Walton, 
    368 N.J. Super. 298
    , 309 (App. Div. 2004) (finding reversible error
    where the trial court instructed the jury on accomplice liability separate from
    the lesser-included offense).     "The trial court must also 'make specific
    A-5556-17T4
    36
    reference to [lesser-included] offenses in the context of its charge on
    accomplice liability.'" 
    Walton, 368 N.J. Super. at 307
    (quoting 
    Harrington, 310 N.J. Super. at 278
    ). A "trial court's failure to refer to accomplice liability
    while giving the lesser included charge [is] reversible error."
    Id. at 307
    (citing
    
    Harrington, 310 N.J. Super. at 279
    ).
    In State v. Schmidt, the defendant was indicted for conspiracy to
    distribute narcotics and possession of narcotics; however, the conspiracy to
    distribute narcotics charge involved dates and parties different from the
    substantive possession charge. 
    110 N.J. 258
    , 265-66 n.1 (1988). The trial
    court failed to instruct the jury that "it could find the defendant guilty of the
    possession counts on the basis of vicarious liability as an accomplice or as a
    conspirator."
    Id. at 265.
    The Court held that "[s]ince the jury charge failed to
    instruct the jury on the vicarious liability of a conspirator as the basis for guilt,
    the constructive possession counts [could not] could not be sustained on that
    basis."
    Id. at 265-66, 275-76.
    The State concedes that the trial court failed to instruct the jury on
    accomplice liability with respect to the aggravated assault by pointing a
    firearm charge but contends that, viewing the jury instructions in their entirety,
    the failure to instruct as to accomplice liability did not lead to an unjust result.
    A-5556-17T4
    37
    The State asserts that the same verdict would have resulted from a correct jury
    instruction. The State also contends that Schmidt is inapposite because the
    jury heard evidence relating to the defendant's charge of conspiracy and could
    have used that theory as a basis to convict defendant of aggravated assault.
    The trial judge did not instruct the jury that Herbert could be vicariously
    liable for the assault charge from his participation in a conspiracy to commit a
    robbery or through accomplice liability. Without these instructions, the jury
    had no basis to find Herbert guilty of aggravated assault by pointing a firearm
    since there was no testimony or evidence presented that Herbert possessed the
    BB gun.     Therefore, the jury would have to rely on either a theory of
    conspiracy or accomplice liability to convict Herbert of the aggravated assault
    by pointing a firearm. The failure to provide an accomplice liability charge on
    the lesser-included aggravated assault offense constituted plain error.
    Accordingly, we reverse Herbert's conviction for aggravated assault and
    remand for retrial.
    V.
    Herbert further argues that the trial court erred by not granting a
    judgment of acquittal on the charges of possession of a firearm for an unlawful
    purpose and aggravated assault by pointing a firearm. We disagree.
    A-5556-17T4
    38
    A defendant may move for judgment of acquittal under Rule 3:18-1 if
    the State has not proven each of the elements of a crime.       A motion for
    judgment of acquittal may be granted if, viewing all the evidence in the light
    most favorable to the State, "as well as all of the favorable inferences which
    could reasonably be drawn therefrom," no "reasonable jury could find guilt of
    the charge beyond a reasonable doubt." State v. Reyes, 
    50 N.J. 454
    , 458-59
    (1967) (citing State v. Fiorello, 
    36 N.J. 80
    , 90-91 (1961)). Such instances of
    guilt may "be based on circumstantial evidence." State v. Franklin, 
    52 N.J. 386
    , 406 (1968) (citing 
    Fiorello, 36 N.J. at 86
    ).
    The Reyes standard applies to appellate review of the sufficiency of
    evidence. State v. Kittrell, 
    145 N.J. 112
    , 130 (1996). "In deciding whether the
    trial court was correct in denying [a Reyes] motion, we . . . take into account
    only the evidence on the State's case, unaided by what defendant later
    developed at trial." State v. Lemken, 
    136 N.J. Super. 310
    , 314 (App. Div.
    1974).
    Herbert moved under Reyes to dismiss the charges of unlawful
    possession and possession for unlawful purpose. The trial court dismissed the
    unlawful possession of a weapon charge but not the possession of a weapon for
    an unlawful purposes charge.
    A-5556-17T4
    39
    Defense counsel did not move to dismiss the aggravated assault by
    pointing a firearm charge. On the contrary, defense counsel moved to include
    the aggravated assault charge as a lesser-included offense. Accordingly, as to
    aggravated assault charge, we review for plain error. R. 2:10-2.
    A person is guilty of possession of a weapon for an unlawful purpose if
    they possess a firearm with the purpose to use it unlawfully. N.J.S.A. 2C:39-
    4(a)(1). A firearm is defined under the statute as:
    any firearm which is in the nature of an air gun, spring
    gun or pistol or other weapon of a similar nature in
    which the propelling force is a spring, elastic band,
    carbon dioxide, compressed or other gas or vapor, air
    or compressed air, or is ignited by compressed air, and
    ejecting a bullet or missile smaller than three-eighths
    of an inch in diameter, with sufficient force to injure a
    person.
    [N.J.S.A. 2C: 39-1(f).]
    The same definition of firearm applies to aggravated assault by pointing a
    firearm charge, "whether or not the actor believes it to be loaded." N.J.S.A.
    2C:12-1(b)(4); N.J.S.A. 2C:39-1(f).
    A BB gun is a firearm within the definition of N.J.S.A. 2C: 39-1(f).
    State v. Mieles, 
    199 N.J. Super. 29
    , 37-38 (App. Div. 1985). An inoperable
    BB gun also qualifies as a firearm under the statute. State v. Austin, 335 N.J.
    A-5556-17T4
    40
    Super. 486, 490 (App. Div. 2000). A "fake or toy gun" does not. State v.
    Gantt, 
    101 N.J. 573
    , 584 (1986).
    As to possession of a firearm for an unlawful purpose, the State need not
    prove the operability of a firearm at the time of the offense; it need only prove
    the firearm was originally designed as operable.
    Id. at 584-85.
    The trial court
    need only be satisfied "that the device was originally designed to deliver a
    potentially-lethal projectile and hence 'real.'"
    Id. at 589.
    To that end, "an
    object's authentic design may be inferred from appearance or based on lay
    testimony, but in no case is it dependent upon empirical examination of the
    weapon."
    Id. at 589-90.
    Indeed, the Gantt Court found sufficient evidence
    existed to support the finding that the weapon involved was a "firearm" even
    though the weapon used in the robbery was never recovered.
    Id. at 591.
    Here, as in Gantt, there was no evidence or testimony to contradict the
    conclusion that the BB gun was real. See
    ibid. Herbert offered no
    evidence
    that the weapon was a toy or fake. Accordingly, the trial court was "justified
    in concluding that the [BB gun] was real and therefore a firearm within the
    meaning of N.J.S.A. 2C:39-1(f)."
    Ibid. Therefore, the trial
    court did not err
    by denying a judgment of acquittal on that count.
    A-5556-17T4
    41
    The same analysis applies to the aggravated assault by pointing charge.
    An instrument may be regarded as a firearm for purposes of aggravated assault
    by pointing a firearm without showing that the instrument was operable at the
    time of the offense. 
    Mieles, 199 N.J. Super. at 38-39
    . Further, "both loaded
    and unloaded weapons should be considered to be firearms in prosecutions for
    aggravated assault under N.J.S.A. 2C:12-1(b)(4)."
    Id. at 38
    (citing State v.
    Bill, 
    194 N.J. Super. 192
    , 198 (App. Div. 1984)).
    On the other hand, the State must prove the operability of a firearm on
    the unlawful possession charge. See N.J.S.A. 2C:39-5(b). Indeed, as to that
    charge, the trial judge recognized that the jury would need to speculate as to
    the operability of the BB gun without expert testimony. No such evidence was
    presented. The trial court properly dismissed that count.
    VI.
    Because we reverse Herbert's convictions and remand for retrial, we do
    not reach his excessive sentencing argument.
    Reversed and remanded for further proceedings and retrial consistent
    with this opinion. We do not retain jurisdiction.
