    COHEN, J.    Following a multi-year inquiry by investigators
    from the Massachusetts Insurance Fraud Bureau and the city of
    Lawrence police department, a grand jury indicted the
    defendants, James C. Hyde, Michael H. Kaplan, and Omar Castillo,
    for crimes arising from the submission of fraudulent automobile
    insurance claims.2   The defendants later were tried together
    before a Superior Court jury.    Hyde, an attorney at the law firm
    of Berger & Hyde, P.C., was convicted of two counts each of
    motor vehicle insurance fraud (see G. L. c. 266, § 111B),
    larceny over $250 (see G. L. c. 266, § 30), and attempted
    larceny over $250 (see G. L. c. 274, § 6).    Kaplan, a
    chiropractor and owner of the Kaplan Chiropractic clinic, was
    convicted of three counts of motor vehicle insurance fraud, and
    two counts each of larceny over $250 and attempted larceny.
    Castillo, an employee of Kaplan Chiropractic, was convicted of
    one count each of motor vehicle insurance fraud and larceny over
    $250.    Before us are the appeals of Hyde and Castillo.3
    2
    Other individuals also were indicted on fraud charges,
    including Leo Lopez and Christopher Ortega, who signed
    cooperation agreements and testified against the defendants.
    3
    Kaplan noticed an appeal, which was stayed while he
    pursued a motion for a new trial. After an evidentiary hearing
    in the trial court, the motion for new trial was denied.
    Subsequently, Kaplan's motion to dismiss his appeal was allowed,
    with prejudice.
    3
    Hyde's convictions resulted from insurance claims submitted
    on behalf of clients purporting to have been injured in two
    staged automobile accidents -- one alleged to have occurred on
    October 1, 2002, and the other alleged to have occurred on
    December 20, 2002.   Hyde's primary contention on appeal is that
    the Commonwealth failed to establish at both the grand jury and
    petit jury stages of the case that he knew that these particular
    accidents were staged.   On this ground, he maintains that both
    his pretrial motion to dismiss the indictments and his motion
    for required findings of not guilty at trial should have been
    allowed.   In addition, Hyde argues that the indictments should
    have been dismissed for the additional reason that the integrity
    of the grand jury proceedings was impaired, and that he is
    entitled to a new trial as a result of the erroneous admission
    of prior bad act evidence.
    Castillo's convictions resulted from his role in helping to
    stage the December 20 accident.   Castillo argues that there was
    insufficient evidence that he knew that statements submitted to
    insurance companies with regard to that accident were false,
    and, therefore, his motion for required findings of not guilty
    should have been allowed.    Castillo also argues that he is
    entitled to a new trial as a result of the erroneous admission
    of checks written to him by Berger & Hyde, P.C.    For the
    following reasons, we affirm both defendants' convictions.
    4
    Background.   The jury could have found the following facts.
    In 2000, Leo Lopez began to work as an assistant and van driver
    at Kaplan Chiropractic.    Shortly after starting the job, Lopez
    brought his mother to Kaplan Chiropractic for treatment of a
    work-related shoulder injury.   When Kaplan gave him $100 in cash
    for bringing his mother in, Lopez learned that it was Kaplan's
    policy to pay his employees cash bonuses when they referred new
    patients to the clinic.    Kaplan later told Lopez that he could
    make extra money by setting up motor vehicle accidents.    Kaplan
    explained how to stage an accident by obtaining two cars (one to
    play the "at fault" role, and the other to play the "not at
    fault" role), recruiting a driver and passengers for each car,
    crashing the cars together, preparing accident reports, and
    bringing the accident participants first to a chiropractor and
    then to an attorney.
    On December 5, 2000, Lopez staged his first accident.        He
    drove his own car, which he was eager to replace, and arranged
    for a woman to hit it with her minivan.    The next day, he went
    to Kaplan for treatment.   At Kaplan's recommendation, Lopez
    promptly went to see Hyde at his law firm.    At that meeting,
    Hyde explained that Lopez would need to accumulate $2,000 in
    5
    medical bills to have a case,4 and gave him an envelope
    containing a check for $200 for bringing the matter to the firm.
    Hyde also promised to "take care of [him]" if he referred more
    clients.
    To build up his medical expenses, Lopez went to a few
    actual physical therapy sessions at Kaplan Chiropractic, and
    then pretended to receive further treatment.       Lopez also went
    back to Hyde's office to fill out a personal injury protection
    form to obtain no-fault benefits for alleged lost wages,5 even
    though he had not stopped working.       Hyde eventually settled
    Lopez's case for $5,300, from which Hyde took $1,325.
    Lopez testified in some detail about the period between
    December, 2000, through September, 2002.       At first, he staged
    "live" two-car collisions, where police and other emergency
    responders would be called to the scene.       However, by mid-2001,
    he had transitioned to staging "paper" accidents.       In those
    instances, he would obtain and damage two cars, recruit people
    willing to pose as the occupants, and fill out paperwork as if a
    real accident had occurred.    The day after each purported
    accident, the persons pretending to be the injured occupants
    4
    Hyde was referring to the so-called tort threshold that is
    a feature of the Massachusetts no-fault insurance scheme. See
    G. L. c. 231, § 6D, as amended by St. 1988, c. 273, § 55.
    5
    See G. L. c. 90, §§ 34A, 34M.
    6
    would be taken to one of two chiropractors and one of two
    lawyers, based on whether they were the designated occupants of
    the "at fault" vehicle or the "not at fault" vehicle.     The
    chiropractor was either Kaplan or another chiropractor who
    practiced at Haverhill Family Chiropractic, and the lawyer was
    either Hyde or another lawyer who practiced at a different firm.6
    Castillo, another van driver for Kaplan, also was engaged
    in the scheme.   He staged accidents, brought the participants to
    Kaplan for treatment, and obtained payments from Kaplan in
    return.   Castillo, too, was introduced to Hyde, and received
    referral fees from Hyde when he brought Hyde new clients.
    Lopez's reputation grew to the point where members of the
    community would approach him to volunteer their participation.
    He enlisted the help of a friend, Christopher Ortega, and paid
    him a share of the referral fees.   The two would recruit
    participants, coach them on their roles in the fictitious
    accidents, and tell them how to respond to medical, legal, and
    insurance professionals.   From December, 2000, through
    September, 2002, Lopez referred participants in more than twenty
    staged accidents to Kaplan Chiropractic or Haverhill Family
    Chiropractic, and to Hyde or the other lawyer involved in these
    6
    The other chiropractor and lawyer also were indicted, but
    those indictments ultimately were dismissed.
    7
    ruses.   Both Kaplan and Hyde would pay Lopez for each individual
    whom he referred to their respective practices.
    As Lopez became friendly with Hyde, the two had a number of
    private conversations where Hyde made specific suggestions about
    how best to stage the accidents.   For example, Hyde told Lopez
    that there were three insurance companies to be avoided, because
    they were "really going hard investigating the accidents."     On
    four or five occasions, Hyde told Lopez to keep the number of
    people in a vehicle to no more than three.   Ortega testified to
    similar conversations with Hyde in which Hyde explained that too
    many passengers "would bring up red flags" with the insurance
    companies.   On the other hand, Lopez also understood from
    discussions with Kaplan, that if there were too few passengers,
    there would not be enough money.   Sometimes Hyde would tell
    Lopez that he should "coach" a nervous client "better," in case
    the insurance company sent out an investigator to ask the client
    questions.   Hyde explained that if the client gave a statement
    that was inconsistent with the accident report, it would raise
    suspicions, and no one would get paid.
    Lopez testified that on more than one occasion in the
    period from December, 2000, through September, 2002, he told
    Hyde that the clients he was referring were from staged
    accidents.   However, Lopez and Ortega also testified that
    sometimes the accident victims they referred were legitimate.
    8
    Ortega estimated that "20 percent [were] real and the rest
    [were] fake."
    The October 1, 2002, and December 20, 2002, staged
    accidents were both paper accidents.     The premise of the October
    1 accident was that a Jaguar driven by Antonia Almanzer and
    carrying two passengers, was struck in the rear by a Ford
    Explorer driven by Kelly Birchall and carrying four passengers.
    Birchall was the godmother of Lopez's son, and had agreed "to
    take the fall."     The accident was orchestrated by Lopez and
    Ortega, who damaged the Explorer by driving it into a wall.        The
    Explorer actually was owned by one of the ostensible passengers,
    who was paid $500 for its use as the "at fault" vehicle.
    Lopez filled out the operator's report for the purported
    driver of the Explorer, supplying information about the two
    vehicles, the names and personal data of the occupants, and a
    description of the accident, including the time, date, and
    location of the collision.     Lopez, along with Ortega, also
    brought the Explorer passengers to Haverhill Chiropractic and
    then to Hyde's law firm.     At the law firm, the passengers met as
    a group with Miguel Nieves, Hyde's associate.     They never met
    Hyde, personally.     Medical bills were generated, and Hyde
    submitted claims on behalf of the passengers.     As a result, the
    insurer paid more than $250 in medical payments to Haverhill
    Chiropractic on behalf of one or more claimants.     By check dated
    9
    October 1, 2002, Lopez received a check for $1,000 from Hyde for
    having referred these clients to him.
    Accompanied by Nieves, the clients later were examined
    under oath by the insurer.    Subsequently, on August 28, 2003,
    the insurer denied the claims in a letter to Hyde stating that
    its investigation revealed that the "accident was not of a
    direct or accidental nature."   The letter explained that the
    examinations under oath "yielded vague and inconsistent
    testimony, especially in regards to what happened before and
    after the loss"; there were no police, ambulance, or fire
    department personnel called to the scene; there were no
    witnesses; and accident reconstruction had determined that the
    damage done to the vehicles "[did] not support a mutual contact
    exchange between the vehicles allegedly involved."    Upon
    receiving the denial letter, Hyde wrote to his clients informing
    them that their claims had been rejected and that he would not
    continue to represent them.
    The December 20, 2002, accident came about when Castillo
    approached Lopez and said that a friend of his, Eddy Ramirez,
    wanted his Mazda MPV minivan totaled.    Lopez then asked Ortega
    to find a second vehicle to play the "at fault" role, so that
    they could create another paper accident.    The premise of the
    December 20 accident was that the MPV, driven by Ramirez and
    transporting three passengers, was struck on the side by a Mazda
    10
    Protege driven by Jose Marti, and carrying three passengers.
    Ramirez, having been given the facts of the accident by
    Castillo, completed an operator's report and submitted it to his
    insurer.   At Castillo's direction, Ramirez and his three
    passengers went to Kaplan for treatment; Castillo also
    accompanied the group to Hyde's law firm.       Lopez remembered
    going with Castillo to this meeting at Hyde's office, and
    informing Hyde in person that he and Castillo were both involved
    and that they would be splitting the referral fee.
    At the law firm, Ramirez and his passengers dealt
    exclusively with Nieves and never met Hyde.         Hyde submitted
    claims for the clients' medical bills, and the insurer made
    payments in excess of $250.       Eventually, however, on November
    21, 2003, the insurer denied the claims stemming from the
    December 20 accident, stating that its investigation had shown
    that "the loss did not occur as alleged by [Hyde's] clients."
    The insurer explained that the "claimants could not provide
    consistent and credible testimony regarding the events
    surrounding the loss, and . . . the two vehicles allegedly
    involved did not collide as described."        Hyde wrote to the
    clients informing them of the denial, and discontinued
    representing them.
    Discussion.      1.    Hyde's arguments.   a.   Sufficiency of the
    evidence at trial.        Each of the crimes of which Hyde was
    11
    convicted requires proof that he knowingly made false statements
    when he submitted the claims.   See Commonwealth v. Charles, 
    428 Mass. 672
    , 683 n.8 (1999); Commonwealth v. Jerome, 
    56 Mass. App. Ct. 726
    , 732 (2002).7   Hyde's argument is that even if the
    Commonwealth adduced sufficient evidence through Lopez and
    Ortega that Hyde knew generally about the scheme, such proof did
    not give rise to a reasonable inference that he knew that the
    October 1 and December 20 accidents were staged, particularly in
    light of the evidence that Lopez and Ortega also sometimes
    referred legitimate accidents to him.
    We consider Hyde's argument under familiar standards.
    Evidence is sufficient to reach the jury, and a motion for a
    required finding of not guilty is properly denied, where the
    7
    A conviction of "[m]otor vehicle insurance fraud, G. L. c.
    266, § 111B, requires that (1) the defendant, in connection with
    a claim under a motor vehicle insurance policy issued by an
    insurer, (2) with the intent to injure, defraud, or deceive such
    insurer, (3) did knowingly present to it, or aid or abet in or
    procure the presentation to it, (4) a notice, statement, or
    proof of loss, (5) knowing that such notice, statement, or proof
    of loss contained a false or fraudulent statement or
    representation, (6) of any fact or thing material to such claim.
    Larceny by false pretenses, G. L. c. 266, § 30 [the theory of
    larceny presented to the jury in this case], requires that (1)
    the defendant knowingly make a false statement, (2) intending
    the person to whom it was made to rely on its truth, (3) the
    person to whom it was made relies on the false statement, and
    (4) based on such reliance, the person parts with personal
    property." Commonwealth v. Charles, 428 Mass. at 683 n.8. The
    third charge, attempted larceny by false pretenses, "require[s]
    a specific intent to commit the underlying offense, an overt act
    towards that commission, and a failure to complete the crime."
    Commonwealth v. Bell, 
    83 Mass. App. Ct. 82
    , 85 (2013).
    12
    evidence, viewed in the light most favorable to the Commonwealth
    and drawing all inferences in favor of the Commonwealth, would
    permit a rational jury to find each essential element of the
    crime beyond a reasonable doubt.     Commonwealth v. Latimore, 
    378 Mass. 671
    , 676-677 (1979).   "A person's knowledge or intent is a
    matter of fact, which is often not susceptible of proof by
    direct evidence, so resort is frequently made to proof by
    inference from all the facts and circumstances developed at the
    trial."   Commonwealth v. Casale, 
    381 Mass. 167
    , 173 (1980).      See
    Commonwealth v. Jerome, 56 Mass. App. Ct. at 732.    "To survive a
    motion for a required finding, it is not essential that the
    inferences drawn are necessary inferences.    It is enough that
    from the evidence presented a jury could, within reason and
    without speculation, draw them."     Commonwealth v. Peck, 
    86 Mass. App. Ct. 34
    , 41 (2014), quoting from Commonwealth v. Gonzalez,
    
    47 Mass. App. Ct. 255
    , 257 (1999).    See Corson v. Commonwealth,
    
    428 Mass. 193
    , 197 (1998).
    Here, the testimony of Lopez and Ortega about their
    conversations with Hyde established that Hyde knew that they
    routinely brought him clients whose accidents were staged.
    While neither Lopez nor Ortega testified that he specifically
    informed Hyde that the October 1 and December 20 accidents were
    fictitious, the jury nevertheless reasonably could infer from
    13
    the circumstances surrounding these accidents that Hyde knew
    they were staged.
    Particularly telling was the number of clients brought to
    Hyde after each of these accidents.    Lopez had testified to his
    understanding that if there were too few occupants, the accident
    would not generate enough money for all concerned; he also had a
    personal incentive to stage accidents involving large numbers of
    occupants, because he received fees for each individual he
    referred.   Indeed, the jury could infer that it was because of
    this incentive that, as Lopez testified, Hyde had found it
    necessary to discuss with him some four to five times the need
    to keep the number of people in the accident vehicles to no more
    than three per vehicle, so as not to raise "red flags" with the
    insurance companies.
    Thus, when four of five occupants of the Ford Explorer
    were brought to his office after the October 1 accident, and all
    four occupants of the Mazda MPV were brought to his office after
    the December 20 accident, Hyde was put on notice that these
    accidents most likely were staged.    Hyde also would have been
    alerted by the fact that, consistent with the attributes of a
    paper accident, in neither the October 1 nor the December 20
    accident were first responders summoned or independent witnesses
    identified.
    14
    When Lopez and Castillo made a point of informing Hyde that
    they were both involved and would split the referral fees
    associated with the December 20 accident, that also signaled
    that this accident was not legitimate.     The jury reasonably
    could infer that Hyde would have understood a fee-splitting
    arrangement between two individuals known to produce staged
    accidents to mean that both had participated in creating it.
    Hyde also would have realized when he submitted the claims to
    the insurers that the clients he obtained from these accidents
    had accumulated substantial medical bills for the treatment of
    relatively minor injuries from which they were slow to recover;
    and Hyde, no less than the insurers that ultimately denied the
    claims, also would have noticed that the damage to the vehicles
    and the participants' stories did not coherently explain the
    alleged events.
    The jury also could consider Hyde's behavior in handling
    the claims.    Although Hyde was the attorney of record on both
    cases, he met with none of the clients he received from the
    October 1 and December 20 accidents.     Instead, he assigned his
    associate, Nieves, to handle all of the personal interactions
    with them.    The jury reasonably could infer that this was Hyde's
    way of distancing himself from claims he knew to be fraudulent.
    Also indicative of Hyde's knowledge was his failure to challenge
    15
    the insurers' denials; instead he promptly abandoned the cases
    and the clients.
    Hyde emphasizes that the above attributes also could be
    consistent with legitimate accidents.    However, the aggregation
    of so many telltale indications sufficed to permit the
    conclusion that Hyde knew that the October 1 and December 20
    accidents were fictitious.    As this court stated in another case
    involving an attorney's submission of fraudulent automobile
    insurance claims, "[w]hile each factor by itself likely would
    not be enough to support conviction," the "circumstances
    present[ed] sufficient evidence of knowledge . . . for a
    rational jury to find the defendant's guilt beyond a reasonable
    doubt."    Commonwealth v. Lonardo, 
    74 Mass. App. Ct. 566
    , 570
    (2009).8
    Hyde's further argument, that the judge erroneously
    employed a lower standard than "actual knowledge," is also
    without merit.   The record reflects that the judge plainly
    utilized an actual knowledge standard in ruling that the
    8
    Hyde accurately points out that Lonardo arose in somewhat
    different circumstances. The defendant in that case was
    convicted of conspiracy to commit automobile insurance fraud,
    and not, as here, of substantive crimes. In the present case,
    although Hyde, Kaplan, and Castillo originally were charged with
    conspiracy, those counts were not tried, and later were placed
    on file with the defendants' consent. Despite this distinction,
    however, the basic underlying principle is the same. In proving
    its case the Commonwealth was not required to adduce direct
    evidence of the defendant's knowledge.
    16
    Commonwealth's case was sufficient to go to the jury.
    Notwithstanding some back and forth discussion of the potential
    applicability of the evidentiary principle of "willful
    blindness,"9 the judge explicitly decided the motion for required
    findings based upon his assessment that "the evidence is such
    that the jury could infer actual knowledge with respect to these
    two episodes."
    The judge's consistent application of the actual knowledge
    standard is further shown by his final charge, where he told the
    jury repeatedly that the Commonwealth was required to prove that
    Hyde had "actual subjective knowledge" that the statements he
    made to the insurers were false, and that it was not enough for
    the Commonwealth to establish that he was "naive or negligent in
    pursuing the truth."   Later, when the jury asked during
    deliberations whether they needed specific evidence for a
    specific indictment, the judge again informed them that it was
    9
    Under this principle, an individual's knowledge may be
    inferred if he intentionally closed his eyes to what would have
    been obvious to him. "A willful blindness instruction is
    appropriate when (1) 'a defendant claims a lack of knowledge,'
    (2) 'the facts suggest a conscious course of deliberate
    ignorance, and' (3) 'the instruction, taken as a whole, cannot
    be misunderstood [by a juror] as mandating an inference of
    knowledge.'" Commonwealth v. Mimless, 
    53 Mass. App. Ct. 534
    ,
    544 (2002), quoting from United States v. Hogan, 
    861 F.2d 312
    ,
    316 (1st Cir. 1988). Attentive to the defendants' arguments,
    and concerned that instructing on willful blindness conceivably
    could give the jury the erroneous impression that they did not
    have to find actual knowledge, the judge here ultimately decided
    not to give such an instruction.
    17
    not enough for the Commonwealth to prove beyond a reasonable
    doubt that the defendant knew that false statements were made in
    connection with other accidents; the Commonwealth was required
    to prove that a false statement was made with respect to the
    accident under consideration and that the defendant had actual
    knowledge that the statement was false.     The judge also
    recharged the jury at length on appropriate and inappropriate
    inferences, and again explained that any inference establishing
    an element, such as knowledge, must be drawn beyond a reasonable
    doubt.
    b.    Evidence of other staged accidents.   Hyde argues that
    it was unduly prejudicial for the jury to hear evidence of
    another staged accident alleged to have occurred on October 10,
    2002, which was uncharged as to him.10    Clients from this
    accident were brought to Hyde's firm, but the claims were
    processed by Hyde's partner, Carl Berger.    The judge initially
    declined to exclude the evidence on the expectation that the
    Commonwealth would establish that Hyde knew about that accident
    or was connected with it in some way.     However, at the end of
    the trial, the judge ruled that the Commonwealth had shown no
    such connection between Hyde (or Castillo, for that matter) and
    the October 10 accident, and charged the jury accordingly.
    10
    Only Kaplan was charged in connection with that accident.
    18
    The judge told the jury that in considering the charges
    against Hyde, the jury could not consider any evidence
    concerning the October 10, 2002, accident, "because there's no
    evidence that Mr. Hyde had any involvement in that matter nor,
    in fact, is there any evidence that Mr. Berger himself was aware
    that anything was amiss, if in fact it was amiss, with respect
    to that accident."   He then repeated the instruction for
    emphasis a moment later.   We are confident that any conceivable
    prejudice to Hyde from the admission of evidence about the
    October 10 accident was prevented by these pointed instructions.
    Hyde also alludes in a footnote to evidence of two other
    uncharged accidents dated January 16, 2002, and March 16, 2002.
    Because "[a]rguments relegated to a footnote do not rise to the
    level of appellate argument," we need not consider his argument.
    Commonwealth v. Springfield Terminal Ry. Co., 
    80 Mass. App. Ct. 22
    , 42 n.32 (2011) (citation omitted).   In any event, Hyde has
    demonstrated no abuse of discretion in admitting evidence of
    these staged accidents, which was necessary to establish
    important background facts about the scheme, including the
    origin of concerns about the number of people in a vehicle and
    Lopez's transition to staging paper accidents.
    c.   Grand jury issues.   Hyde renews his claims, rejected by
    the trial judge, that he was entitled to the allowance of his
    motion to dismiss the indictments.   He first claims that the
    19
    grand jury heard no direct evidence that he knew that the
    accidents for which he was indicted were staged, and, therefore,
    his motion should have been allowed pursuant to Commonwealth v.
    McCarthy, 
    385 Mass. 160
     (1982).    Hyde does not dispute that the
    testimony of several witnesses (including Ortega and two other
    referrers who brought him clients from staged accidents)
    established that, in other instances, he knew that he was
    representing clients whose claims were not legitimate.     His
    argument is that, as to the October 1 and December 20 accidents,
    the Commonwealth impermissibly asked the grand jury to infer
    guilty knowledge based upon evidence of wrongdoing at other
    times, and that everything he did with respect to the October 1
    and December 20 accidents "was as consistent with processing a
    legitimate case as processing a known fabricated accident."
    In reviewing the evidence before the grand jury we keep in
    mind that "an indictment requires a finding of probable cause."
    Commonwealth v. Riley, 
    73 Mass. App. Ct. 721
    , 726 (2009).       This
    is a far lower standard than that needed to survive a motion for
    a required finding of not guilty at trial.    "The quantum of
    evidence required to indict and commence prosecution is . . .
    considerably less exacting than that required of the petit jury
    that adjudicates guilt."   
    Ibid.
    Here, the circumstantial evidence of Hyde's knowledge about
    the October 1 and December 20 accidents was of substantially the
    20
    same character as the trial evidence previously discussed.
    Ortega and two other referrers testified generally about staging
    accidents and to conversations with Hyde reflecting his
    awareness that he was receiving clients from accidents that were
    not legitimate.   Ortega testified that, after staging an
    accident and bringing the participants to the chiropractor, he
    would call Hyde's office to make sure that Hyde was there, bring
    in the participants, and give Hyde the accident report.     Hyde
    would meet with Ortega and Lopez privately in his office and
    look through the report to make sure everything was in order.
    Hyde would ask if the participants had been coached as to the
    facts of the accident, and, on occasion, would dispense guidance
    as to how best to set up the accidents so as not to raise any
    flags.    Ortega specifically testified that he had such closed
    door meetings in connection with the charged accidents.     This
    testimony, as well as other evidence showing that the October 1
    and December 20 accidents bore the earmarks of being staged,
    permitted the grand jury to find probable cause to believe that
    Hyde knew that the claims he submitted as a result of these
    accidents were fraudulent.   See Commonwealth v. Riley, 73 Mass.
    App. Ct. at 731 ("grand jury may . . . infer[] . . . knowledge
    and intent from all the facts and circumstances presented").
    Contrast Commonwealth v. Reveron, 
    75 Mass. App. Ct. 354
    , 357-359
    (2009).
    21
    Hyde also contends that the integrity of the grand jury
    proceedings was impaired and, hence, his motion to dismiss
    should have been allowed under Commonwealth v. O'Dell, 
    392 Mass. 445
     (1984).    However, "[t]o sustain a claim that the integrity
    of the grand jury proceeding has been impaired, not only must
    the evidence have been given with knowledge that it was false or
    deceptive, but the false or deceptive evidence must probably
    have been significant in the view of the grand jury and must
    have been presented with the intention of obtaining an
    indictment."    Commonwealth v. Mayfield, 
    398 Mass. 615
    , 621
    (1986).   See Commonwealth v. Mathews, 
    450 Mass. 858
    , 876 (2008).
    Hyde has not met these criteria here.
    Hyde first points to the testimony of an investigator from
    the Insurance Fraud Bureau, and, specifically, to the
    investigator's testimony about so-called "runners."     The
    investigator testified to the effect that runners are people
    who, under the direction of chiropractors and attorneys,
    orchestrate staged accidents and recruit participants for those
    accidents.     Hyde argues that this testimony improperly implied
    that the use of "runners" to bring in business was, in itself,
    criminal.    As the investigator explained, however, this was how
    the term "runner" was used in the insurance industry, and the
    investigator did not know how other people would define it.
    22
    Suffice it to say that the grand jury heard conflicting
    testimony on this topic.   Ortega testified along the same lines
    as the investigator about the role of "runners."     On the other
    hand, there was testimony from two other witnesses that runners
    are simply nonlawyers who bring in clients for a fee.     The
    function of the acknowledged "runners" in this case, including
    Lopez and Ortega, ultimately was for the grand jury to decide
    based upon the weight and credibility of the evidence.
    Commonwealth v. Riley, 73 Mass. App. Ct. at 727.11
    Hyde also points to the testimony of a witness who did not
    speak English and who claimed to have spoken with Hyde about
    staged accidents through a translator identified only as "Jose."
    However, Hyde has not shown that the witness's testimony was
    falsely or inaccurately presented to the grand jury in any way.
    Even if it was left unclear how well Jose interpreted what Hyde
    said to the witness, it was for the grand jury to evaluate the
    strengths and weaknesses of this evidence.
    Hyde also claims that the Commonwealth failed adequately to
    inform the grand jury that Ortega had received inducements to
    testify.   Citing Commonwealth v. Mayfield, 
    398 Mass. at 620-621
    ,
    11
    Another statement of the investigator challenged by Hyde,
    that Hyde represented runners who brought accidents to him, was
    true, even if not corroborated. Nor do other alleged
    inaccuracies in the investigator's testimony rise to the level
    of potentially affecting the fairness of the grand jury process.
    23
    Hyde characterizes such information as exculpatory evidence that
    greatly undermined Ortega's credibility.       However, we need not
    reach the issue, because the grand jury knew full well before
    voting on the indictments, that Ortega was benefiting from his
    cooperation with the Commonwealth.       It is true that the first
    time he testified, on September 14, 2007, Ortega stated that
    there were no promises made to him in connection with his
    appearance at the grand jury proceedings that day.       However, the
    second time he testified, the Commonwealth asked him a series of
    questions about his cooperation agreement, and Ortega admitted
    that he had agreed to cooperate with the investigation and had
    signed a letter to that effect on July 19, 2007.       The agreement
    then was presented to the grand jury.
    In sum, it is questionable whether any of the challenged
    testimony was seriously misleading; but even if the grand jury
    heard inaccurate information, Hyde has failed to show that the
    Commonwealth offered any testimony knowing that it was false or
    deceptive, or that such testimony probably influenced the grand
    jury's determination to indict.
    2.      Castillo's arguments.   a.   Sufficiency of the evidence
    at trial.    There is no merit to Castillo's argument that the
    Commonwealth failed to prove that he knew that statements made
    to insurance companies in connection with the December 20
    accident were false.     The evidence showed not only that Castillo
    24
    knew the December 20 accident was staged, but that he had
    instigated that accident with the intention of financially
    benefiting a friend.
    Lopez testified that Castillo approached him about staging
    the December 20 accident so that Castillo's friend, Ramirez,
    could have his minivan totaled.    Castillo told Lopez that he had
    his party all set and that all he needed was an "at fault"
    vehicle.    Lopez and Ortega then found the at fault vehicle and
    put together the staged accident.     After the accident, Castillo
    directed the people in Ramirez's vehicle to Kaplan and Hyde.
    Lopez and Castillo went to Hyde's office together to inform him,
    in person, that they were jointly involved and would split the
    referral fee.   This evidence was more than sufficient to
    establish that Castillo knew and intended that false claims
    would be submitted by Hyde.    Any conflicts in the evidence as to
    the nature and extent of Castillo's participation were for the
    jury to resolve.
    b.     Admission of checks.   Castillo was charged only in
    connection with the December 20 accident.    He therefore objected
    to the introduction of Berger & Hyde, P.C., checks written to
    him at other times, on the basis that the jury could draw an
    unfair inference that the other checks also represented payments
    for insurance fraud schemes that the defendant simply "didn't
    get caught on."    "Whether evidence is relevant and whether its
    25
    probative value is substantially outweighed by its prejudicial
    effect are matters entrusted to the trial judge's broad
    discretion and are not disturbed absent palpable error."
    Commonwealth v. Simpson, 
    434 Mass. 570
    , 578-579 (2001).     See
    Mass. G. Evid. § 403 (2015).   Here, the judge could conclude in
    his discretion that the checks were highly probative of
    Castillo's referral relationship with Hyde.     Furthermore, the
    admission of the checks was cumulative and nonprejudicial.    Luke
    Goldworm, an investigator with the Attorney General's Office,
    testified to the same facts without objection or challenge on
    appeal, i.e., that Berger & Hyde, P.C., had issued Castillo six
    checks that totaled about $2,500.12
    Judgments affirmed.

    To the extent that we have not specifically addressed
    subsidiary arguments in the defendants' briefs, they have not
    been overlooked. "We find nothing in them that requires
    discussion." Commonwealth v. Domanski,
