                       ________________

GRUENDER, Circuit Judge.

       Sangeeta Mann (“Mann”) appeals her convictions for conspiring to obstruct an
official proceeding and aiding and abetting evidence tampering. For the reasons set
out below, we affirm.
I.    BACKGROUND

        Mann’s charges stem from a federal grand jury investigation into a well-
publicized bombing attack in West Memphis, Arkansas, that targeted the then-
chairman of the Arkansas State Medical Board. Shortly after the bombing, Mann’s
husband (“Dr. Mann”), a physician whose license to dispense controlled substances
had been revoked previously by the Board, was interviewed by agents with the
Bureau of Alcohol, Tobacco, Firearms and Explosives (“ATF”). Less than a month
later, after a chance discovery by a municipal worker of a large cache of unregistered
hand grenades buried near Dr. Mann’s house, ATF agents executed a search warrant
at Dr. Mann’s house, found a number of unregistered firearms, and arrested Dr.
Mann. After his arrest, in recorded phone calls from jail, Dr. Mann discussed with
Mann the ongoing investigation and his expectation that federal agents would soon
conduct additional searches. Dr. Mann instructed Mann to remove certain items from
his medical office before it was searched, and she promptly complied.

       A Second Superceding Indictment charged Dr. Mann with a number of counts
related to the bombing and with the knowing possession of unregistered high
explosive grenades and unregistered firearms. It charged both Mann and Dr. Mann
with conspiring to obstruct an official proceeding, in violation of 18 U.S.C.
§ 1512(c)(2), (k), and with aiding and abetting evidence tampering, in violation of 18
U.S.C. §§ 1512(c)(1), 2. Mann was also charged with making a false material
declaration while under oath, in violation of 18 U.S.C. § 1623. Mann filed an initial
motion to sever before the Second Superceding Indictment was filed and a
supplemental motion after it was filed. In both, she argued that joinder of her charges
with those of her husband was inappropriate under Federal Rule of Criminal
Procedure 8 and that severance of her charges from those of her husband was
warranted under Federal Rule of Criminal Procedure 14(a) because joinder would




                                         -2-
result in “extreme prejudice” to her. The district court1 denied each of Mann’s
motions, as well as a subsequent motion to sever filed by Dr. Mann and adopted by
Mann.

      The district court seated a jury after the distribution of jury questionnaires and
an almost week-long voir dire process. The trial of Mann and Dr. Mann lasted over
three weeks. On the third day of its deliberations, the jury returned guilty verdicts
against Mann on both of the § 1512 charges and a not-guilty verdict on her § 1623
charge. It returned guilty verdicts against Dr. Mann on all of the charges relating to
the bombing, on both of the § 1512 charges, and on all but one of his charges relating
to possession of illegal firearms and explosives.

      After trial, Mann filed a motion for a judgment of acquittal or for a new trial,
which the district court denied. At her sentencing hearing, the district court
calculated Mann’s advisory sentencing guidelines range as 46 to 57 months’
imprisonment, but then varied downward and sentenced Mann to 12 months’
imprisonment. Mann appeals her convictions on various grounds.

II.   DISCUSSION

       Mann makes four arguments on appeal. First, she renews her joinder and
severance arguments. Second, she argues that she was denied her Sixth Amendment
right to an impartial jury. Third, she contends that an ex parte communication that
occurred between the trial judge and jury necessitates an evidentiary hearing to
determine its propriety. Fourth, she challenges the denial of her motion for a
judgment of acquittal on the grounds of evidentiary insufficiency.




      1
       The Honorable Brian S. Miller, United States District Judge for the Eastern
District of Arkansas.

                                          -3-
      A. Joinder and Severance

       Mann argues that the district court erred in joining her case with Dr. Mann’s
and then abused its discretion in denying her motion to sever. She contends that the
joint trial was prejudicial to her because it included the presentation of evidence
related to the “numerous bad acts of [her] husband and co-defendant.” “[T]he
severity and complexity of [Dr. Mann’s] charged offenses, the media coverage, and
the emotional nature of the charges and evidence” created, in her view, a “high risk
of undue prejudice.”

      Joinder is a question of law, and we therefore review claims of misjoinder de
novo. United States v. Liveoak, 377 F.3d 859, 864 (8th Cir. 2004). “[A]n error
involving misjoinder . . . requires reversal only if the misjoinder results in actual
prejudice because it ‘had substantial and injurious effect or influence in determining
the jury’s verdict.’” United States v. Lane, 474 U.S. 438, 449 (1986) (quoting
Kotteakos v. United States, 328 U.S. 750, 776 (1946)).

       We review a district court’s denial of a motion to sever made pursuant to
Federal Rule of Criminal Procedure 14 for abuse of discretion, Liveoak, 377 F.3d at
864, reversing only when the district court’s denial “resulted in severe or compelling
prejudice,” United States v. Rimell, 21 F.3d 281, 289 (8th Cir. 1994). “Severe
prejudice occurs when a defendant is deprived of an appreciable chance for an
acquittal, a chance that [the defendant] would have had in a severed trial.” United
States v. Garrett, 648 F.3d 618, 625-26 (8th Cir. 2011) (quoting United States v.
Koskela, 86 F.3d 122, 126 (8th Cir. 1996)). The burden of establishing prejudice falls
on the defendant. Id. at 626. “Severance is not required merely because evidence that
is admissible only against some defendants may be damaging to others.” United
States v. Mickelson, 378 F.3d 810, 818 (8th Cir. 2004).

                                         -4-
       Even if Mann could show either misjoinder or an abuse of discretion in failing
to sever, Mann’s claims on each of these legal grounds fails because she cannot
demonstrate the prejudice necessary for reversal under either claim. “When there are
few defendants and the trial court is aware of the potential for prejudice, ‘the risk of
transference of guilt over the border of admissibility [may be] reduced to the
minimum’ by carefully crafted limiting instructions with a strict charge to consider
the guilt or innocence of each defendant independently.” Lane, 474 U.S. at 450 n.13
(alteration in original) (quoting Blumenthal v. United States, 332 U.S. 539, 560
(1947)).

      Mann has not challenged on appeal the adequacy of the district court’s well-
constructed and lengthy jury instructions. The jury was instructed to:

      give separate consideration to the evidence about each individual
      defendant. Each defendant is entitled to be treated separately, and you
      must return a separate verdict for each defendant. Also keep in mind
      that you must consider, separately, each crime charged against each
      individual defendant, and must return a separate verdict for each of
      those crimes charged.

“The risk of prejudice posed by joint trials is best cured by careful and thorough jury
instructions.” Mickelson, 378 F.3d at 818; see also United States v. Avila Vargas,
570 F.3d 1004, 1009 (8th Cir. 2009). In addition, Dr. Mann’s bombing and firearms
charges were sufficiently distinct from Mann’s obstruction and evidence-tampering
charges that we see no reason to question the ability of the jury to compartmentalize
the evidence presented on each charge against each defendant. See United States v.
Lewis, 557 F.3d 601, 610-11 (8th Cir. 2009). Indeed, powerful proof of the efficacy
of the district court’s instructions and of the jury’s ability to compartmentalize the
evidence is the fact that Mann and Dr. Mann each were acquitted on one count. See
United States v. Pherigo, 327 F.3d 690, 693 (8th Cir. 2003) (“In our consideration of
the jury’s ability to compartmentalize the evidence against the joint defendants, we
consider . . . if one or more of the defendants were acquitted.”); United States v.

                                          -5-
Wadena, 152 F.3d 831, 849 (8th Cir. 1998) (holding a jury’s acquittal of defendants
on certain counts to be evidence of the jury’s ability to compartmentalize evidence).

      In light of the district court’s careful instruction of the jury and the jury’s
apparent ability to consider each defendant and each count individually, Mann has not
demonstrated prejudice resulting either from the joining of her case with Dr. Mann’s
or from the district court’s denial of her motion to sever. In the absence of such
prejudice, we will not reverse on this basis.

      B. Jury Impartiality

        “[T]he criminally accused [have a right to] a fair trial by a panel of impartial,
indifferent jurors.” Irvin v. Dowd, 366 U.S. 717, 722 (1961) (internal quotation
marks omitted). “Voir dire serves the purpose of assuring a criminal defendant that
this right will be protected.” United States v. Ortiz, 315 F.3d 873, 888 (8th Cir. 2002).
“Trial judges have broad discretion in determining how best to conduct voir dire,
though this discretion is not without boundaries.” Id. “Because the trial judge is in
the best position to analyze the demeanor and credibility of a venireman, we will not
reverse a court’s rulings absent an abuse of discretion.” Id.

       Mann asserts that she was denied her right to an impartial jury. She points to
the jury questionnaires collected at the outset of the voir dire process, which she
contends “show that racial prejudice, religious and cultural prejudice, and media
saturation and bias had compromised the jury pool, and made it impossible to select
an impartial jury.” She also points to comments made at voir dire by jurors who were
eventually seated, which she argues show similar disqualifying prejudice.

       Because Mann raises this issue for the first time on appeal, we review for plain
error only. See United States v. Ali, 616 F.3d 745, 751-52 (8th Cir. 2010). For us to
find plain error, Mann would have “to show that (1) there was an error that was not

                                          -6-
affirmatively waived, (2) the error was ‘plain,’ meaning clear and obvious, (3) the
error affects [her] substantial rights, and (4) the error ‘seriously affects the fairness,
integrity or public reputation of judicial proceedings.” Id. at 752 (quoting Puckett v.
United States, 556 U.S. 129, 135 (2009)). She fails to meet this stringent burden.

       As an initial matter, the jury Mann alleges was irretrievably compromised by
bias acquitted her on a perjury charge and her husband on one of his firearms charges.
In Skilling, the Supreme Court found a jury’s acquittal of a defendant on some counts
to be a factor of “prime significance” in assessing potential jury bias, stating that “[i]t
would be odd for an appellate court to presume prejudice in a case in which jurors’
actions run counter to that presumption.” Skilling v. United States, 561 U.S. ---, 130
S. Ct. 2896, 2916 (2010); see also United States v. Arzola-Amaya, 867 F.2d 1504,
1514 (5th Cir. 1989) (“The jury’s ability to discern a failure of proof of guilt of some
of the alleged crimes indicates a fair minded consideration of the issues.”). We
therefore consider Mann’s claims in light of the significant fact of her acquittal on the
§ 1623 charge.

       Jury selection stretched across four days in this case. Ninety-two potential
jurors completed questionnaires that asked for information as to racial, ethnic, or
religious bias, as to preconceptions and beliefs about guns and gun policy, and as to
media exposure. The district court excused twenty-four for cause on the basis of their
questionnaire answers. Fifty-seven of the remaining potential jurors were subjected
to a searching, extensive, and individualized voir dire process, during which a further
seventeen were excused for cause. Ultimately, thirty-eight were qualified as jurors
by the district court. After both parties exercised their peremptory strikes, twelve
jurors and three alternates were seated without objection.

      Mann identifies no irregularities in this process other than marginal answers
given by jurors either on their questionnaires or during voir dire. All of these
problematic answers were scrutinized by both parties and the district court and in all

                                           -7-
instances were found to be unproblematic. For example, Mann points to one seated
juror’s statement that she “would probably tend to trust a U.S. citizen more” than a
foreigner, but the juror in question was in fact seated without objection after she went
on to affirm that she would not “treat [the Manns] any differently than [she] would”
native-born Americans and that she believed that “Dr. Mann and his wife are . . .
entitled to a fair and impartial jury.” Mann points to a second seated juror who stated
in his questionnaire that he was in favor of government regulation of the types and
number of firearms one can own. He went on to affirm during voir dire, though, that
he would not “convict someone just because they had guns” and that he was “okay”
with the fact that, “[u]nder the law, it is possible to own a machine gun legally if you
do certain things.” This juror, too, was seated without objection. In all of the
instances that Mann identifies of a seated juror purportedly stating something
objectionable during voir dire, the juror, under further questioning, alleviated any
concern raised to the satisfaction of the district court and the parties.

       Mann essentially asks us to interfere with the district court’s credibility
determinations, an uncomfortable prospect in itself, and she has provided us no valid
factual or legal reason to do so. See United States v. Rodriguez, 581 F.3d 775, 788
(8th Cir. 2009) (“[I]f the district court accepts assurance that [the jurors] will set aside
any preconceived beliefs, the court’s ruling is a credibility finding.”); see also
Skilling, 130 S. Ct. at 2918 (“Reviewing courts are properly resistant to second-
guessing the trial judge’s estimation of a juror’s impartiality, for that judge’s appraisal
is ordinarily influenced by a host of factors impossible to capture fully in the
record—among them, the prospective juror’s inflection, sincerity, demeanor, candor,
body language, and apprehension of duty.”); Mu’Min v. Virginia, 500 U.S. 415, 428
(1991) (“A trial court’s findings of juror impartiality may ‘be overturned only for
manifest error.’” (quoting Patton v. Yount, 467 U.S. 1025, 1031 (1984))). We decline
the invitation.




                                            -8-
      C. Ex Parte Communication

       “[T]he right to personal presence at all critical stages of the trial” is a
fundamental right of criminal defendants. Rushen v. Spain, 464 U.S. 114, 117 (1983).
Ex parte communications between judge and jury “are improper and presumptively
prejudicial.” United States v. Koskela, 86 F.3d 122, 125 (8th Cir. 1996). However,
“a clear indication of an absence of prejudice” can overcome this presumption, id.,
and the presumption does not apply to contacts between judge and jury that are
merely “ministerial” in nature and not “substantive” communications, see Shelton v.
Purkett, 563 F.3d 404, 408 (8th Cir. 2009).

       Mann contends that an ex parte communication between the judge and jury
may have affected the jury’s verdict and, relying on Rushen, requests a remand for an
evidentiary hearing into the nature of the communication. She bases this contention
on the district court’s statement to the jury in open court, immediately before the
recital of final jury instructions:

      [A]s I told you back in the jury room about 15 minutes ago, we’ve been
      working since we saw you yesterday on all of our jury instructions, and
      we went from whatever time we got out yesterday afternoon to 8:30 last
      night. We started back up at 10:00 o’clock this morning. We were able
      to come up with 32 initial instructions, which I’m about to give you.

In Rushen, though, the Supreme Court noted that a remand for an evidentiary hearing
is required only in instances when a trial judge fails to disclose an ex parte
communication to counsel for all parties. Rushen, 464 U.S. at 119 (“When an ex
parte communication relates to some aspect of the trial, the trial judge generally
should disclose the communication to counsel for all parties. The prejudicial effect
of a failure to do so, however, can normally be determined by a post-trial hearing.”).
Here, the district court informed the parties and their counsel in open court of the



                                         -9-
contents of his ex parte communication shortly after it occurred, and Rushen therefore
does not require us to order an evidentiary hearing.

       Moreover, “it has been recognized that ‘a court’s ex parte communication with
the jury will not require a reversal where substantive rights of parties have not been
adversely affected.’” Powell v. Kroger Co., 644 F.2d 1245, 1247 (8th Cir. 1981) (per
curiam) (quoting Petrycki v. Youngstown & N. R.R., 531 F.2d 1363, 1367 (6th Cir.
1976)). Because, in this case, it is clear that the court’s communication with the jury
was ministerial and not substantive and that neither party was denied the opportunity
to object or make a record, we conclude that the ex parte contact in question did not
affect Mann’s substantive rights because it was not prejudicial to her. See id.
Because the ex parte communication was disclosed to the parties and because we find
here “a clear indication of an absence of prejudice,” Koskela, 86 F.3d at 125, we see
no need for a remand for an evidentiary hearing.

      D. Judgment of Acquittal

       “We consider challenges to the sufficiency of the evidence to support a
conviction de novo but consider the evidence presented ‘in the light most favorable
to the government, resolving conflicts in the government’s favor, and accepting all
reasonable inferences that support the verdict.’” United States v. Diaz-Pellegaud,
666 F.3d 492, 498 (8th Cir. 2012) (quoting United States v. Yarrington, 634 F.3d 440,
449 (8th Cir. 2011)), petition for cert. filed (U.S. June 1, 2012) (No. 11-10972),
petition for cert. filed (U.S. June 14, 2012) (No. 11-10908). “Reversal for evidentiary
insufficiency is only warranted when, based on the evidence before it, ‘no reasonable
jury could have found the defendant guilty beyond a reasonable doubt.’” Id. (quoting
United States v. Espinosa, 585 F.3d 418, 423 (8th Cir. 2009)).




                                         -10-
             1. Conspiracy to Obstruct an Official Proceeding

       Mann was convicted of conspiracy to obstruct justice within the meaning of 18
U.S.C. § 1512(c)(2) by, inter alia, corruptly removing certain items at Dr. Mann’s
direction from his office in anticipation of a search and having friends dispose of
items for her while the investigation was ongoing. Section 1512(c)(2) criminalizes
corruptly “obstruct[ing], influenc[ing], or imped[ing] any official proceeding, or
attempt[ing] to do so.” Conspiring to commit any substantive offense in § 1512 is
proscribed by 18 U.S.C. § 1512(k). “[O]fficial proceeding” for the purposes of
§ 1512(c)(2) is defined as including “a proceeding before a judge or court of the
United States . . . or a Federal grand jury.” 18 U.S.C. § 1515(a)(1)(A). Mann
contends that there was insufficient evidence presented at trial to sustain her
conviction.

       At trial, the Government presented recordings of phone calls made between
Mann and Dr. Mann after his arrest while the federal grand jury investigation into the
bombing was still ongoing. During some of these calls, recorded prior to the
execution of a search warrant at Dr. Mann’s medical office, Mann and Dr. Mann
talked about firearms and “Dan’s papers” that were located at Dr. Mann’s office and
the fact that Dr. Mann’s attorney had told him that a search of the office was
imminent. The name “Dan” apparently referred to the Manns’ son Kundan Mann.
Steven Briscoe, a man imprisoned with Dr. Mann, testified at trial that Dr. Mann told
him that Dan had been involved in the bombing. In a later phone call, recorded the
day after ATF agents searched the office and found no firearms or papers belonging
to Dan, Mann told her husband about the search and, after he asked her whether she
had removed anything from the office before the search, she responded, “We did
good. We did good.”

      Phillip and Rita Barthelme testified that, shortly after Dr. Mann’s arrest and
before the execution of search warrants at the Mann house and office, Mann had

                                        -11-
asked them to haul away from her house and dispose of a carload and a small
truckload of items, most of which the Barthelmes later burned. Although Phillip
described the load of items as just “stuff that [Mann] didn’t want anymore,” including
furniture, clothing, and books, and Rita described it as “basically just junk,” ATF
agents who later inspected the Barthelmes’ burn pile found the scorched remains of
a three-ring bank binder with the name “Sunny Mann” on it, a nickname of Sandip
Mann, Mann’s brother-in-law. Sandip Mann was a person of interest in the
investigation because of his complicated financial relationship with Mann and Dr.
Mann and because of an email sent to him by Dr. Mann that included a picture of and
specifically identified the Arkansas State Medical Board chairman targeted in the
bombing.

       This evidence, construed in the light most favorable to the Government and
buttressed with “all reasonable inferences” that could have been made based on it, see
Diaz-Pellegaud, 666 F.3d at 498, could have reasonably led the jury to find that
Mann and Dr. Mann corruptly conspired to impede the investigation into Dr. Mann
by, inter alia, removing potentially relevant evidence, including materials relating to
Dan and Sandip Mann, from Dr. Mann’s office in anticipation of a warrant search.
The evidence presented at trial was therefore sufficient to sustain Mann’s conviction
on this count.

              2. Aiding and Abetting Tampering with Evidence

       Mann also was convicted of aiding and abetting tampering with evidence in
violation of 18 U.S.C. § 1512(c)(1) by removing from Dr. Mann’s medical office a
special power of attorney, a general power of attorney, pre-signed blank checks, and
other financial documents related to Sandip Mann, her brother-in-law, before a search
warrant was executed there. Section 1512(c)(1) prohibits, inter alia, corruptly
“conceal[ing] a record, document, or other object, or attempt[ing] to do so, with the
intent to impair the object’s integrity or availability for use in an official proceeding.”

                                           -12-
An “official proceeding” includes a proceeding before a federal judge, court, or grand
jury, 18 U.S.C. § 1515(a)(1)(A), and “an official proceeding need not be pending or
about to be instituted at the time of the offense,” 18 U.S.C. § 1512(f)(1). Mann
contends first that there was no “official proceeding” within the meaning of the
statute because there was no official proceeding focusing on Sandip Mann
specifically. She also argues that there is insufficient evidence that her actions were
related to any official proceeding or that she corruptly concealed the documents in
question.

      Mann’s first argument is flawed. Section 1512(f)(1) specifically provides that
no “official proceeding need . . . be pending or about to be instituted at the time of the
offense.” Thus, § 1512(c)(1) requires only that Mann have acted with the intent to
impair the documents’ availability to an official proceeding. It does not require the
Government to prove the existence of an official proceeding focusing on Sandip
Mann. Furthermore, notwithstanding Mann’s protestations to the contrary, the
Government never argued that there was an official proceeding to investigate Sandip
Mann specifically but rather argued that he was a person of interest in the ongoing
federal grand jury investigation into the bombing, which clearly was an official
proceeding within the meaning of the statute. See 18 U.S.C. § 1512(c)(1); 18 U.S.C.
§ 1515(a)(1)(A).

      Mann’s second argument also fails. She contends that the Government failed
to meet its burden of showing an intent to impair an official proceeding because it had
not shown a sufficient nexus between a proceeding and her conduct. She relies
primarily on the Supreme Court’s decision in United States v. Aguilar, 515 U.S. 593
(1995), in which the Court construed a jury tampering statute as requiring the charged
conduct to “have a relationship in time, causation, or logic with the judicial
proceedings.” Id. at 599. Under Aguilar, “the endeavor must have the ‘natural and
probable effect’ of interfering with the due administration of justice.” Id. (quoting

court that has applied the Aguilar nexus requirement to § 1512(c)(1), some courts
have applied Aguilar to § 1512(c)(2). See, e.g., United States v. Reich, 479 F.3d 179,
186 (2d Cir. 2007). It is not necessary for us to decide whether Aguilar applies to
§ 1512(c)(1), however, because, even if we were to assess the evidence presented
against her in light of Aguilar, Mann’s argument would still fail.

       Several days before the execution of the search of Dr. Mann’s office, and after
Dr. Mann was told by his lawyer that a search of the office was imminent, Dr. Mann
told Mann to remove certain items from the office and to give them to either Gerald
Riley or another man. Mann retrieved the documents related to Sandip Mann from
the office and gave them to Riley with instructions to hold onto them for her. She
collected them from Riley about a day later. On a subsequent visit to Riley’s home,
Mann offered to hire an attorney for Riley and told him that he did not have to
cooperate with prosecutors or with the ATF. Riley told Mann that he already had
been contacted by the ATF and that they knew about the envelope he had held for her,
in response to which Mann said, “They don’t know everything.” In subsequent
testimony before the grand jury, Mann was confronted about the Sandip Mann
documents, ultimately admitted that she removed the documents from the office prior
to the search, and eventually turned them over pursuant to a subpoena.

       The jury could have reasonably inferred from this sequence of events that, by
removing documents related to Sandip from the office shortly before the search and
by then giving them to a trusted friend of the family to hold, Mann corruptly intended
to impair the availability of these documents to the ongoing grand jury investigation
and that her actions had “a relationship in time, causation, or logic with the judicial
proceedings” such that their “‘natural and probable effect’ [was] interfer[ing] with the
due administration of justice.” Aguilar, 515 U.S. at 599 (quoting Wood, 6 F.3d at
695). Therefore, the evidence was sufficient to support Mann’s conviction on this
count.

III.   CONCLUSION

       For the foregoing reasons, we affirm the judgment of the district court.
