    OPINION
    ______________________
    SHWARTZ, Circuit Judge.
    Defendant Abdur Razzak Tai appeals his conviction
    and sentence for mail and wire fraud in connection with
    claims for payment from the Fen-Phen Settlement Trust. Tai
    argues that the District Court committed plain error by
    implicitly shifting the burden of proof in its “willful
    blindness” jury instruction and applying upward adjustments
    under the advisory Sentencing Guidelines for abuse of a
    position of trust, use of a special skill, and aggravated role.
    For the reasons set forth below, we conclude that the District
    Court’s jury instruction and its upward adjustments based
    upon position of trust and special skill were not in error, but
    we will remand to enable the District Court to make the
    2
    required factual findings concerning whether Tai supervised a
    criminally culpable subordinate, which is necessary to award
    an aggravated role enhancement.
    I
    In the late 1990s, individuals who had taken the
    prescription diet-drug combination commonly known as Fen-
    Phen began filing lawsuits against American Home Products
    Corporation (“AHP”), the predecessor of Wyeth, claiming
    that the drugs caused valvular heart disease. In 2000, the
    United States District Court for the Eastern District of
    Pennsylvania approved a class action settlement (the
    “Settlement”), which included the establishment of the Fen-
    Phen Settlement Trust (the “Trust”), through which Wyeth
    paid compensation to class members who demonstrated that
    they sustained valvular heart damage.
    Financial compensation for these heart conditions was
    determined under a pre-established matrix.1 To receive
    compensation, claimants were required to provide a recording
    of and a physician’s report about an echocardiogram
    (“echo”)2 and a document referred to as a “Green Form”3
    1
    The amount of a claimant’s benefits was determined
    by several factors, including the length of time the claimant
    used Fen-Phen, the severity of the claimant’s valvular heart
    condition, and the claimant’s age.
    2
    Typically, a technician performed and video recorded
    the echoes, and a qualified physician reviewed the video and
    the technician’s worksheet setting forth the measurements.
    3
    The Green Form provided the formulae for
    determining if the claimant had a condition that qualified for
    3
    signed by a board-certified cardiologist or cardiothoracic
    surgeon with Level 2 training in echocardiography.4 The
    Trust then reviewed the submissions and, when appropriate,
    tendered payment.
    A representative of the Trust explained that the Trust
    relied on the integrity of the physicians signing the reports
    and Green Forms to ensure that the claimants actually had
    heart conditions that were covered by the Settlement. Both
    the Trust and Wyeth had “audit rights,” which allowed them
    to have highly trained, board-certified physicians review the
    materials submitted to ensure “the tape . . . matche[d] with the
    rest of the substantiation.” App. 87. Under the original terms
    of the Settlement, only 15% of all claims could be audited. In
    November 2002, the District Court ordered that 100% of the
    claims would be subject to audit because of concerns about
    the bona fides of the claims being submitted.5
    compensation. Part II of the Green Form required the
    physician to sign beneath a warning that explained that it was
    an official court document and the physician was declaring,
    under penalty of perjury, that the information on the form was
    correct.
    4
    Level 2 training reflects a high degree of experience
    reading and interpreting echoes.
    5
    On March 15, 2005, the District Court approved an
    amendment to the Settlement (the “Seventh Amendment”),
    under which Wyeth agreed to create a new supplemental fund
    with a separate, faster process for reviewing and paying
    claims for which there was documentation that on its face
    qualified the claimant for Matrix Benefits. The Seventh
    Amendment claims were all subject to medical review.
    4
    Attorneys who represented certain Fen-Phen claimants
    retained Tai, a board-certified and Level 2-qualified
    cardiologist, to read echoes and prepare reports to submit to
    the Trust. Tai estimated that he read 12,000 echoes for this
    purpose, and asserted that he was owed over $2 million
    dollars for the services he provided. This amount was based
    upon a fee for each echo read and a bonus payment for each
    approved payment.6 Most of the Green Forms Tai signed
    were submitted before the 100% audit rule was imposed.
    Tai acknowledged to law enforcement that in about
    10% of the cases, he dictated physician’s reports consistent
    with the findings in the technicians’ reports despite knowing
    that the measurements were wrong. He also admitted that he
    had his technician and office manager, Debbie Patrick, review
    about 1,000 of the echoes because he did not have the time to
    do the work himself. Patrick testified, via deposition, that she
    reviewed “a couple hundred” echoes, App. 605, and provided
    Tai with her notes to “help him out” with the volume of
    echoes he was asked to review. App. 589-90. Patrick
    testified that she did not know whether Tai read the echoes
    himself before signing the physician’s report and Green
    Form, but she “would assume that he did because there were
    several times that [she] even asked him” if he agreed with her
    conclusions and he sometimes told her she was wrong. App.
    591-92. For one particular lawyer representing Fen-Phen
    claimants, Tai signed more than 1,400 Green Forms, and of
    the 1,173 of those Green Forms that were audited or
    reviewed, only 109 were approved. A government expert
    6
    For example, one attorney agreed to pay Tai a $100-
    150 fee for each echo read, plus an additional “expert fee” of
    $900-1000 for each Green Form that the Trust approved.
    5
    reviewed a nonrandom sample of the forms Tai submitted for
    this attorney and found that, in a substantial number of the
    cases, the measurements were not only clearly incorrect, but
    were actually inconsistent with a human adult heart.7
    Tai was charged in a thirteen-count indictment for
    mail and wire fraud, in violation of 18 U.S.C. §§ 1341 and
    1343, respectively. The jury found Tai guilty of all charges,
    and he was sentenced to concurrent sentences of 72 months’
    imprisonment8 and three years’ supervised release, and
    ordered to pay restitution of $4,579,663, a fine of $15,000,
    and a special assessment of $1,300. Tai appeals.
    7
    Tai testified that he agreed with these conclusions but
    claimed that the signature on the physician reports attributed
    to him was not his. Tai’s employees, however, testified that it
    was his signature, and, in fact, his office administrator
    testified that she had stamped Tai’s signature on the reports
    with his permission.
    8
    The base offense level was 7, 18 levels were added
    under U.S.S.G. § 2B1.1(b)(1)(J) (loss was more than $2.5M
    but less than $7M), 2 levels were added under U.S.S.G. §
    3B1.3 (defendant used a special skill or abused his position of
    trust), and 2 levels were added under U.S.S.G. § 3B1.1(c)
    (defendant was an organizer, leader, manager or supervisor).
    This resulted in an offense level of 29, with an applicable
    advisory Guidelines range of 87-108 months. The District
    Court then granted a two-level variance following
    consideration of the Section 3553(a) factors due to Tai’s age
    and health, and lowered the offense level from 29 to 27, with
    an applicable Guidelines range of 70-87 months. The Court
    sentenced Tai near the bottom of that range to 72 months’
    imprisonment.
    6
    II9
    The parties agree that none of the issues Tai presents
    were preserved for appeal and that plain error review
    applies.10 United States v. Couch, 
    291 F.3d 251
    , 252-53 (3d
    Cir. 2002) (stating that where no objection to the Guidelines
    calculation was preserved at sentencing, it is reviewed for
    plain error); United States v. Antico, 
    275 F.3d 245
    , 265 (3d
    Cir. 2001) (reviewing a jury instruction for plain error where
    the challenge on appeal was not raised at trial); Fed. R. Crim.
    P. 30(d), 52(b). The defendant bears the burden to establish
    plain error. United States v. Olano, 
    507 U.S. 725
    , 734-35
    (1993). For reversible plain error to exist, there must be (1)
    an error; (2) that is plain; (3) that affects substantial rights;
    and (4) which seriously affects the fairness, integrity, or
    public reputation of judicial proceedings. Johnson v. United
    States, 
    520 U.S. 461
    , 466-67 (1997).
    9
    The District Court had jurisdiction pursuant to 18
    U.S.C. § 3231, and this Court has jurisdiction pursuant to 28
    U.S.C. § 1291.
    10
    At argument, the Government for the first time
    argued that Tai waived his right to appeal the role
    enhancement because he withdrew his objection to its
    imposition before sentencing. While we recognize that
    withdrawing an objection constitutes a waiver of the right to
    appellate review in most instances, we will not foreclose
    appellate review in this case, where the Government did not
    rely on waiver in its brief and enforcing the waiver rule here
    would not serve “the interests of justice.” United States v.
    Barrow, 
    118 F.3d 482
    , 491 (6th Cir. 1997).
    7
    III
    A. Jury Instruction
    We will first address whether the District Court
    committed plain error by employing the language of the Third
    Circuit’s model jury instruction when instructing the jury
    about willful blindness. Tai argues that the model jury
    instruction is constitutionally infirm because it shifts the
    burden of proof to the defendant to disprove intent.
    A willful blindness instruction is typically delivered in
    the context of explaining how the Government may sustain its
    burden to prove that a defendant acted knowingly in
    committing a charged offense. Here, the willful blindness
    instruction was delivered after the District Court explained
    the elements common to mail and wire fraud, including that
    the Government must prove that Tai “acted knowingly with
    respect to an element of the offenses.” Supp. App. 824. The
    District Court defined “knowingly” as meaning “that the
    Government must prove beyond a reasonable doubt that he
    was conscious and aware of the nature of his actions and of
    the surrounding facts and circumstances as specified in the
    definition of the offenses charged.” 
    Id. The District
    Court
    then instructed the jury as follows:
    As I just explained, members of the jury,
    to find Dr. Tai guilty of mail fraud or wire
    fraud, you must find that the Government
    proved beyond a reasonable doubt that Dr. Tai
    knowingly devised or wil[l]fully participated in
    8
    a scheme to defraud, and that he acted with
    intent to defraud.
    Both of these elements involve the
    question of whether Dr. Tai had knowledge of
    an inaccuracy of the echocardiogram reports
    and green form[s] that he signed.
    When, as in this case, knowledge of a
    particular fact or circumstance is an essential
    part of the offense charged, the Government
    may prove that Dr. Tai knew of the fact or
    circumstance if the evidence proved beyond a
    reasonable doubt that Dr. Tai deliberately
    closed his eyes to what would otherwise have
    been obvious to him.
    No one can avoid responsibility for a
    crime by deliberately ignoring what is obvious;
    thus, you may find that Dr. Tai knew about the
    falsity of the echo reports and green forms
    based on evidence which proves that, one, Dr.
    Tai himself actually subjectively believed that
    there -- there was a high probability that the
    reports or forms were not accurate, and, two,
    Dr. Tai consciously took deliberate actions to
    avoid learning about the existence of the falsity.
    You may not find Dr. Tai knew that the
    reports or forms were not accurate if you find
    that the defendant actually believed that the
    reports and forms were accurate. Also, you
    may not find that Dr. Tai knew the reports and
    forms were not accurate if you -- you find only
    that Dr. Tai consciously disregard [sic] a risk
    that the reports and the forms were not
    accurate or that Dr. Tai should have known
    9
    that the reports and forms were not accurate,
    or that a reasonable person will have known
    of a high probability that the reports and
    forms were not accurate.
    It is not enough that Dr. Tai may have
    been reckless or stupid or foolish or may have
    acted out of accident. You must find that Dr.
    Tai himself actually subjectively believed that
    there was a high probability that the reports and
    forms were not accurate, consciously took
    deliberate actions to avoid learning about their
    inaccuracy and did not actually believe that they
    were accurate.
    Supp. App. 828-30 (emphasis added). Tai argues that the
    emphasized phrases in the fifth paragraph told the jury that
    certain innocent states of mind preclude a finding of
    knowledge, and he asserts that this suggests to the jury that it
    can find that Tai did not meet the element of knowledge only
    if the jury finds those innocent states of mind to have existed.
    This in turn, Tai argues, impermissibly shifts the burden from
    the government to Tai to disprove his knowledge.
    There is no doubt that a jury instruction violates due
    process if it fails to place squarely on the Government the full
    burden of proving beyond a reasonable doubt the required
    mental state for the offense. See Patterson v. New York, 
    432 U.S. 197
    , 204-07 (1977).            The language of the fifth
    paragraph, however, did not impose any burden, implicit or
    explicit, on Tai to prove or disprove his knowledge. Rather,
    the willful blindness jury instruction as a whole came after
    the jury was told the Government bears the burden to prove
    that Tai acted knowingly and with an intent to defraud. The
    10
    willful blindness instruction then explicitly explained that
    “the Government may prove” this element through evidence
    that established beyond a reasonable doubt that Tai
    “deliberately closed his eyes to what would otherwise have
    been obvious to him.” Supp. App. 829. The instruction then
    explained to the jury what this meant and how it could not
    find him guilty if the jury found that Tai actually believed the
    forms were accurate, that he disregarded a risk of inaccuracy,
    or that he or a reasonable person should have known the
    reports were inaccurate. The instruction then reiterated that,
    to convict, the jury must find Tai subjectively believed there
    was a high probability the reports were inaccurate and he
    consciously took steps to avoid learning about their
    inaccuracy. These instructions told the jury when willful
    blindness does or does not exist, but did not imply in any way
    that Tai must present evidence concerning his own beliefs or
    knowledge. Thus, there was no implicit or explicit shifting of
    the burden of proof to Tai.11
    11
    Courts have approved similar instructions. United
    States v. Flores, 
    454 F.3d 149
    , 158 (3d Cir. 2006) (stating that
    a willful blindness instruction saying that “[i]f the [evidence]
    shows you that [the defendant] actually believed . . .”
    reflected the “correct burden of proof”); see also United
    States v. Clay, 
    618 F.3d 946
    , 952 & n.5 (8th Cir. 2010)
    (approving the following in a willful blindness instruction:
    “You may not find [defendant] acted ‘knowingly’ if you find
    he was merely negligent, careless, or mistaken . . . . You may
    not find that [defendant] acted knowingly if you find that he
    actually believed . . .” and finding no merit to the argument
    that this instruction shifted the burden of proof).
    11
    Moreover, the District Court told the jury that it could
    not find knowledge based on a willful blindness theory unless
    the Government proved Tai’s knowledge beyond a reasonable
    doubt, and in fact the jury was expressly told at the beginning
    of the instructions that Tai never had to prove anything, and
    that the burden always remained on the government.12 This
    was “more than sufficient to dispel any possible
    misconception that [Tai] bore a burden to prove that he was
    not willfully blind.” United States v. Flores, 
    454 F.3d 149
    ,
    159 (3d Cir. 2006) (holding that even when the district court
    had misspoken and erroneously shifted the burden of proof in
    its willful blindness instruction, repeated references to the
    government’s burden and the district court’s general
    instruction that the burden does not shift ensured that there
    was no plain error). When the instructions are read as a
    whole, it is clear that no jury could conclude that Tai bore the
    burden of proof as to any aspect of his knowledge and the
    District Court committed no error in connection with its
    willful blindness instruction.
    12
    The District Court instructed that
    [t]he presumption of innocence means that the
    defendant has no burden or obligation to present
    any evidence at all or to prove that he is not
    guilty. The burden or obligation of proof is on
    the Government to prove that the defendant is
    guilty, and this burden stays with the
    Government throughout the entire trial.
    Supp. App. 818-19.
    12
    B. Sentence
    1. Abuse of a Position of Trust or use of a Special Skill
    under U.S.S.G. § 3B1.3
    Tai argues that the District Court plainly erred by
    imposing a two-level increase under U.S.S.G § 3B1.3 for
    abuse of a position of trust and use of a special skill. Section
    3B1.3 allows an increase of two offense levels “[i]f the
    defendant abused a position of public or private trust, or used
    a special skill, in a manner that significantly facilitated the
    commission or concealment of the offense.” Because either
    an abuse of a position of trust or use of a special skill supports
    the two-level enhancement the District Court applied, Tai
    must establish plain error with respect to both to avoid it. We
    will examine each separately.
    a. Abuse of Position of Trust
    To receive an enhancement for abusing a position of
    trust, the facts must show that the defendant took “criminal
    advantage of a trust relationship between himself and his
    victim.” United States v. Hickman, 
    991 F.2d 1110
    , 1112 (3d
    Cir. 1993). Courts consider the following three factors to
    determine whether a position of trust or a trust relationship
    exists: “(1) whether the position allows the defendant to
    commit a difficult-to-detect wrong; (2) the degree of authority
    which the position vests in defendant vis-a-vis the object of
    the wrongful act; and (3) whether there has been reliance on
    the integrity of the person occupying the position.”13 United
    13
    Tai argues that the position of trust guideline applies
    only to those who were selected or paid for by the entity with
    13
    States v. Dullum, 
    560 F.3d 133
    , 140 (3d Cir. 2009) (internal
    quotation marks omitted). Once a position of trust has been
    found, § 3B1.3 requires a finding that the defendant “abused
    that position in a way that significantly facilitated his crime.”
    United States v. Sherman, 
    160 F.3d 967
    , 969 (3d Cir. 1998)
    (internal quotation marks omitted).
    As to the first factor, Tai’s position as a cardiologist
    with Level 2 training in echocardiology allowed him to
    commit a difficult-to-detect wrong. Only an equally well-
    trained physician was permitted to support claims for
    payment and only one with access to the same patient
    information would be able to detect Tai’s fraud. Indeed, it
    would be impossible to verify the accuracy of his reports
    whom the trust relationship is said to exist. He provides no
    support for this position and, indeed, our precedent makes
    clear that this is not a requirement. See United States v.
    
    Sherman, 160 F.3d at 967
    , 970 (3d. Cir. 1998) (holding that a
    doctor was in position of trust with insurance company who
    insured his patients). At argument, Tai tried to distinguish
    Sherman on the grounds that insurance companies approve
    providers under a health insurance plan and are therefore in a
    pre-existing trust relationship with those providers. Our
    analysis in Sherman, however, did not make this distinction,
    as we did not focus on whether the insurance company had
    pre-approved the doctor, but instead concentrated on the fact
    that “the insurance company relied on the integrity of
    Sherman as a doctor holding a medical license.” 
    Id. Like the
    insurance company in Sherman, the Trust accepted Tai’s
    representations because of his expertise.
    14
    without a second and similarly qualified doctor reviewing the
    same information.14
    As to the second factor, Tai had a large degree of
    authority over the submission of the claims as he was one of
    the physicians authorized to read echoes and sign Green
    Forms for submission to the Trust. Moreover, his license and
    experience allowed him to do so without supervision.
    As to the third factor, the very nature of the Settlement
    and structure of the Trust required reliance on the integrity of
    the doctors who were signing the physician reports and Green
    Forms. To verify the existence of qualifying heart damage,
    the Trust depended upon the fact that licensed and board-
    certified cardiologists or cardiothoracic surgeons with Level 2
    training in echocardiography had reviewed the claimants’
    echoes and had prepared and signed reports attesting to the
    findings under penalty of perjury. See United States v. Liss,
    
    265 F.3d 1220
    , 1229 (11th Cir. 2001) (“Of the other circuits
    that have addressed whether a physician occupies a position
    of trust in relation to Medicare, or a private insurance carrier,
    14
    Tai relies on United States v. DeMuro, 
    677 F.3d 550
    (3d Cir. 2012), in which this Court held that the “difficult to
    detect” factor of the position of trust analysis had not been
    proven when defendants had failed to pay taxes that they had
    withheld from employees’ paychecks and placed into a trust
    fund account the IRS required defendants to maintain. 
    Id. at 555,
    567-68. The defendants in DeMuro, however, did not
    exercise any professional judgment in their actions vis-a-vis
    the IRS trust fund on which the IRS relied, and thus that
    situation is very different from the one here.
    15
    all have answered that question in the affirmative.”). It was
    reasonable for the Trust to have relied upon Tai’s
    representations both based on his training and the fact that to
    have a second doctor “shadow him” would be an
    unreasonable expense. 
    Sherman, 160 F.3d at 970
    .
    Finally, Tai’s credentials, and the deference he was
    accorded as a result of them, placed him in a position that
    facilitated his criminal conduct. His signature gave claimants
    the opportunity to receive, collectively, hundreds of millions
    of dollars in compensation, yielding more than $2 million in
    potential payments to him.
    The Trust’s ability to audit claims does not mean that
    the Trust limited the authority the doctors were given to
    submit claims and the expectation that they would have done
    so honestly. See 
    Sherman, 160 F.3d at 970
    . Rather, the
    Trust depended almost exclusively on the professional
    integrity of the physicians who submitted reports and signed
    Green Forms under penalty of perjury, particularly during the
    period Tai submitted most of the claims. Many of Tai’s
    reports were signed and completed when the Trust and Wyeth
    were entitled to audit up to only 15% of the claims.
    Moreover, the audit looked only at whether any reasonable
    physician could have reached the conclusion of the certifying
    cardiologist that the claimant had the heart condition depicted
    in the echocardiogram tape, and thus the audit was geared
    toward accepting the medical judgments of the highly trained
    physicians who rendered them. Cf. 
    Sherman, 160 F.3d at 970
    (upholding abuse of trust adjustment for a physician who
    occupied a position of trust with the insurance company to
    which he submitted inflated bills and rejecting defendant’s
    argument that his authority to act was narrowed by insurance

    company oversight via regular audits of bills submitted to
    them).
    For these reasons, the District Court did not plainly err
    in finding Tai abused a position of trust and enhancing his
    sentence under § 3B1.3.
    b. Use of Special Skill
    Although the abuse of a position of trust alone is
    sufficient to justify the two-level enhancement under § 3B1.3,
    we will also examine whether it was plain error to find that
    Tai also used a special skill. The following two factors must
    be present to support the application of an upward Guidelines
    adjustment for use of a special skill: “(1) the defendant
    possesses a special skill; and (2) the defendant used it to
    significantly facilitate the commission or concealment of the
    offense.” United States v. Batista De La Cruz, 
    460 F.3d 466
    ,
    468 (3d Cir. 2006).
    Tai admits that he possessed a special skill as a highly
    trained doctor but argues instead that he does not meet the
    second prong of the test because he did not use his special
    skill to commit his crimes as he refrained from exercising his
    skill when he did not review the echoes and simply signed the
    reports.
    Here, Tai’s skill and credentials were the means by
    which he could participate in the claims process. Without
    them, he would not have been permitted to submit reports to
    support claims and collect a fee. Moreover, without his
    training, Tai would have lacked the skill to review the videos
    of the echoes, would have been unable to determine whether
    17
    the technicians’ conclusions were correct or incorrect, and
    would have been unable to decide whether a particular case
    was one that was wrong but that he would “let . . . go.” Supp.
    App. 645-46; see United States v. Lewis, 
    156 F.3d 656
    , 659
    (6th Cir. 1998) (“Unlike simply billing for a procedure that
    has not been performed, exaggerating the nature of a medical
    procedure does require the use of special medical
    knowledge.”). Thus, Tai’s special skill was integral to his
    commission of his crimes and the District Court did not err in
    finding Tai used a special skill to commit his crime.
    2. Aggravated Role under U.S.S.G. § 3B1.1(c) 15
    Lastly, Tai argues that his two-level leadership
    enhancement under U.S.S.G. § 3B1.1(c) was unwarranted.
    Section 3B1.1 allows for a two-level enhancement if the
    defendant was “an organizer, leader, manager, or supervisor
    in any criminal activity” with fewer than five participants. A
    participant is defined as “a person who is criminally
    15
    If the enhancement under § 3B1.3 had been based
    only on the use of a special skill, the role enhancement would
    not apply. See U.S.S.G § 3B1.3 (“[I]f this adjustment is
    based solely on the use of a special skill, it may not be
    employed in addition to an adjustment under § 3B1.1
    (Aggravating Role).” (emphasis added)); 
    Hickman, 991 F.2d at 1112
    & n.5 (accord, but noting that the basis for this
    distinction is unclear and the connection “between . . .
    supervising others and using a special skill [is] elusive”).
    Because we conclude that the enhancement is applicable
    based upon both the abuse of a position of trust and use of a
    special skill, it is appropriate to consider the application of a
    role enhancement.

    responsible for the commission of the offense, but need not
    have been convicted. A person who is not criminally
    responsible for the commission of the offense (e.g., an
    undercover law enforcement officer) is not a participant.”
    U.S.S.G. § 3B1.1 cmt. n.1. To be deemed “a participant
    under the Guidelines,” the “individual must be criminally
    responsible, i.e., s/he must have committed all of the elements
    of a statutory crime with the requisite mens rea.” United
    States v. Badaracco, 
    954 F.2d 928
    , 934-35 (3d Cir. 1992).
    Thus, to apply the enhancement, “the government must prove
    by a preponderance of the evidence that the [alleged
    participants] were criminally responsible participants.” 
    Id. at 935.
    Tai initially objected to the inclusion of this
    enhancement. After receiving the Government’s sentencing
    memorandum, Tai sent a letter to the District Court
    withdrawing the objection. As a result, the Government
    presented no additional evidence concerning this
    enhancement at sentencing and the District Court made no
    factual findings concerning its applicability other than to say:
    An additional two levels were added pursuant to
    the guideline section 3B1.1(c) because he was
    an organizer, leader, a manager or supervisor in
    criminal activity[,] based on his employment of
    a non-physician technologi[st] whom he
    directed to read echocardiograms and then
    prepared     and      signed    a    physician’s
    echocardiogram report falsely implying or
    asserting the conclusions were the result of his
    own observations and conclusions.
    
    19 Ohio App. 672-73
    (emphasis added). Absent from this recitation
    is any statement about whether the “technologist” had the
    requisite state of mind to be deemed criminally responsible.
    Furthermore, to the extent the District Court incorporated by
    reference the explanation in the PSI concerning the role
    adjustment, the PSI also lacked facts from which to conclude
    that the technologist acted with the requisite mens rea. 16
    Under our precedent, the culpable participation of the person
    being supervised is central to the applicability of an upward
    16
    The PSI, which the District Court adopted, stated the
    following as the basis for applying the § 3B1.1 adjustment:
    Adjustments for Role in the Offense: The
    defendant employed a technologist in his office,
    identified as D.P., who was qualified to conduct
    echocardiograms, but who was not a physician,
    and did not have Level II training in
    echocardiography. In order to save his own
    time, and in abrogation of his obligation to
    exercise independent medical judgment, the
    defendant      directed     D.P.      to    read
    echocardiograms that had been submitted by . . .
    attorneys who represented persons who claimed
    to have been injured as a result of having
    ingested Fen-Phen, and then prepared and
    signed physician’s echocardiogram reports that
    falsely implied or asserted that his conclusions
    were the result of his own observations and
    conclusions. Pursuant to U.S.S.G. § 3B1.1(c),
    two levels are added.
    PSI ¶ 54.

    adjustment for role. The question here then is whether the
    absence of such a finding of criminal culpability of a
    participant constitutes plain error. We conclude that it does.
    First, the error was plain, as Badaracco has been the
    law of this Circuit since 1992, and to sentence Tai based on
    his role supervising a technologist in the absence of any
    finding about that person’s culpability is contrary to
    established law.
    Second, the error affects Tai’s substantial rights, as it
    affects the length of his sentence. United States v. Pollen,
    
    978 F.2d 78
    , 90 (3d Cir. 1992). Here, the two-level
    enhancement for an aggravated role raised Tai’s advisory
    Guidelines offense level from 27 to 29, with an advisory
    range of 87-108 months. The District Court varied downward
    by two offense levels from that range because of Tai’s age
    and health, and imposed a term at the low end of the 70-87
    month range of 72 months’ imprisonment. If the offense
    level had not been enhanced for an aggravated role, then the
    Guidelines offense level would have been calculated at 27,
    and if the District Court had applied the same variance, it
    would therefore have lowered the offense level to 25, with an
    applicable range of 57 to 71 months. If the District Court
    had again chosen to sentence near the bottom of that range,
    then the sentence could have been less than five years, which
    is a year shorter than the sentence he received.
    Finally, we exercise our discretion to correct the error
    because it increased the sentence without the necessary fact
    finding and thereby affected the integrity of the proceedings.
    United States v. Saferstein, 
    673 F.3d 237
    , 244 (3d Cir. 2012)
    (concluding that a higher sentencing range “too seriously
    21
    affects the fairness, integrity, or public reputation of judicial
    proceedings to be left uncorrected” (internal quotation marks
    omitted)). We are unwilling to speculate about the facts on
    which it was based, particularly in a situation like this, where
    the decision may have been based on a credibility
    determination or where there may be facts beyond the trial
    record that may have been considered had Tai not withdrawn
    his objection to the role enhancement. Thus, we express no
    view as to the applicability of the enhancement but rather, to
    ensure the integrity of the proceedings, we will remand for
    resentencing to allow the District Court to make factual
    findings concerning the culpability of the individuals with
    whom Tai worked and impose the enhancement if it finds at
    least one of these participants was criminally culpable.
    
    Pollen, 978 F.2d at 90
    .
    III
    For the foregoing reasons, we will affirm the judgment
    of conviction and vacate and remand the judgment of
    sentence to address the applicability of the role enhancement.
