Unpublished opinions are not binding precedent in this circuit. USCA4 Appeal: 24-4307 Doc: 33 Filed: 03/30/2026 Pg: 2 of 7
PER CURIAM:
A federal jury convicted Jalen Craig McMillan of conspiracy to commit bank fraud,
in violation of 18 U.S.C. § 1349; three counts of bank fraud, in violation of 18 U.S.C.
§ 1344; and aggravated identity theft, in violation of 18 U.S.C. § 1028A. The charges
stemmed from a scheme in which McMillan and several coconspirators used stolen
identities to open accounts at the credit union where McMillan worked; these accounts
were used to obtain loans or other sources of funds, which would then be withdrawn in
cash and the proceeds distributed among the coconspirators. The district court sentenced
McMillan to 54 months’ imprisonment, followed by a five-year term of supervised release,
and ordered him to pay $165,891.68 in restitution. On appeal, McMillan argues that the
district court erred by allowing testimony from two Government witnesses and denying his
motion for a judgment of acquittal. For the following reasons, we affirm.
We review evidentiary rulings for abuse of discretion. United States v. Simmons,
11 F.4th 239, 261 (4th Cir. 2021). If a district court abuses its discretion, its evidentiary
rulings are reviewed for harmless error and will not be reversed so long as we can “say
with fair assurance, after pondering all that happened without stripping the erroneous action
from the whole, that the judgment was not substantially swayed by the error.” United
States v. Cloud, 680 F.3d 396, 401 (4th Cir. 2012) (citation modified). We review
unpreserved evidentiary challenges for plain error. United States v. Watkins, 111 F.4th
300, 311 (4th Cir. 2024). To demonstrate plain error, McMillan must show that (1) an
error occurred, (2) the error was clear, (3) the error affected his substantial rights, and (4)
2 USCA4 Appeal: 24-4307 Doc: 33 Filed: 03/30/2026 Pg: 3 of 7
the error “seriously affects the fairness, integrity, or public reputation of judicial
proceedings.” Id.
McMillan contends that the district court erred in permitting Joseph Kropff, an
investigative financial analyst who was not offered as an expert witness, to provide expert
testimony. Under Fed. R. Evid. 702, a witness “qualified as an expert by knowledge, skill,
experience, training, or education” may give opinion and other testimony if: “the expert’s
. . . knowledge will help the trier of fact;” the testimony “is based on sufficient facts or
data” and “is the product of reliable principles and methods;” and “the expert has reliably
applied the principles and methods to the facts of the case.” Fed. R. Evid. 702. Under Fed.
R. Evid. 701, a lay witness may “give opinion testimony that is rationally based on the
witness’s perception . . . so long as it is not based on the same scientific, technical, or other
specialized knowledge covered by Rule 702.” Lord & Taylor, LLC v. White Flint, L.P.,
849 F.3d 567, 575 (4th Cir. 2017) (citation modified); see Fed. R. Evid. 701.
“A critical distinction between Rule 701 and Rule 702 testimony is that an expert
witness must possess some specialized knowledge or skill or education that is not in the
possession of the jurors.” Certain Underwriters at Lloyd’s, London v. Sinkovich, 232 F.3d
200, 203 (4th Cir. 2000) (citation modified). “At bottom . . . Rule 701 forbids the admission
of expert testimony dressed in lay witness clothing, but it does not interdict all inference
drawing by lay witnesses.” United States v. Perkins, 470 F.3d 150, 156 (4th Cir. 2006)
(citation modified).
McMillan challenges testimony Kropff gave while describing how he developed
McMillan as a suspect in the bank fraud scheme. The parties disagree as to whether
3 USCA4 Appeal: 24-4307 Doc: 33 Filed: 03/30/2026 Pg: 4 of 7
McMillan properly preserved this challenge for appeal. However, because McMillan does
not prevail even under the preserved error standard, we need not decide whether
McMillan’s objection was sufficient to preserve the error.
The challenged testimony was based on Kropff’s personal perception of the
evidence during his investigation and his conclusion “call[ed] more for the exercise of
common sense than expertise.” United States v. Smith, 962 F.3d 755, 768 (4th Cir. 2020).
We therefore find that the district court did not abuse its discretion in allowing this
testimony.
McMillan next challenges the district court’s admission of testimony by Jovan Bell,
a coconspirator. McMillan argues that, under Hammer v. United States, 271 U.S. 620
(1926), a defendant cannot be convicted based on the uncorroborated testimony of an
accomplice, and therefore Bell’s testimony was insufficient to convict him. Because this
claim was not raised at trial, we review for plain error.
To the extent that McMillan challenges the court’s admission of Bell’s testimony,
he does not offer a basis for why it should be excluded, and there is none apparent on the
record. To the extent that McMillan challenges the sufficiency of Bell’s testimony to
convict him, his argument is without merit. “[I]t is well settled in this circuit that the
uncorroborated testimony of an accomplice may be sufficient to sustain a conviction.”
United States v. Robertson, 68 F.4th 855, 863 (4th Cir. 2023) (citation modified).
Moreover, the holding in Hammer applies only to cases involving perjury, which is not at
issue in this case. 271 U.S. at 627-29. Accordingly, we find that the district court did not

plainly err in admitting Bell’s testimony, and that such testimony was sufficient to sustain
McMillan’s conviction.
McMillan’s final challenge on appeal is to the district court’s denial of his Fed. R.
Crim. P. 29 motion for a judgment of acquittal. He argues that the Government failed to
present sufficient evidence to show his knowledge and participation in the conspiracy to
commit bank fraud beyond a reasonable doubt. We “review de novo a district court’s
denial of a Rule 29 motion.” United States v. Burfoot, 899 F.3d 326, 334 (4th Cir. 2018).
We “must sustain a guilty verdict if, viewing the evidence in the light most favorable to
the prosecution, the verdict is supported by substantial evidence.” Id. “Substantial
evidence is that which a reasonable finder of fact could accept as adequate and sufficient
to support a conclusion of a defendant’s guilt beyond a reasonable doubt.” Id. (citation
modified). “Reversal for insufficient evidence is reserved for the rare case where the
prosecution’s failure is clear.” United States v. Wolf, 860 F.3d 175, 194 (4th Cir. 2017)
“When a defendant raises specific grounds in a Rule 29 motion, grounds that are not
specifically raised are waived on appeal unless a manifest miscarriage of justice has
occurred.” United States v. Duroseau, 26 F.4th 674, 678 (4th Cir. 2022) (citation
modified). We have clarified, however, that “‘forfeiture’ is the more precise term.” Id. at
678 n.2. That is because “forfeiture is the failure to make the timely assertion of a right,”
which is reviewed for plain error, and “courts do in fact review the newly asserted grounds
for Rule 29 motions to determine if a manifest miscarriage of justice occurred.” Id.
(citation modified); see United States v. Rao, 123 F.4th 270, 276 (5th Cir. 2024) (“Under
5 USCA4 Appeal: 24-4307 Doc: 33 Filed: 03/30/2026 Pg: 6 of 7
[the manifest miscarriage of justice] standard, the court assesses whether the record is
devoid of evidence pointing to guilt, or the evidence on a key element of the offense is so
tenuous that a conviction would be shocking.” (citation modified)).
In his Rule 29 motion, McMillan raised only a challenge to the sufficiency of the
Government’s evidence that he was the person who sent the incriminating text messages
from his cell phone. To the extent that his argument on appeal encompasses the issue of
who sent the texts from McMillan’s phone, the Government introduced evidence that his
phone was seized from his person, his phone was protected with a passcode, and text
messages regarding planning and executing the fraudulent transactions were sent and
received by his phone while the transactions took place and at times while McMillan was
working at the credit union. Viewing the evidence in a light most favorable to the
Government, there was substantial evidence establishing the incriminating text messages
sent from McMillan’s phone were sent by McMillan.
To the extent that McMillan otherwise challenges the sufficiency of the
Government’s evidence of his knowledge and participation in the conspiracy, he did not
raise this claim in his Rule 29 motion, so it is forfeited absent a manifest miscarriage of
justice. To secure a conviction for conspiracy to commit bank fraud, the government must
demonstrate: “(1) that two or more persons agreed to commit bank fraud; and (2) that at
some time during the conspiracy, the defendant had knowledge of the criminal objective
of the agreement and willfully joined the conspiracy with the intent to further its unlawful
purpose.” United States v. Vinson, 852 F.3d 333, 351 (4th Cir. 2017).
6 USCA4 Appeal: 24-4307 Doc: 33 Filed: 03/30/2026 Pg: 7 of 7
In addition to introducing text messages from McMillan’s phone wherein he
planned and participated in the conspiracy and bank fraud, the Government also produced
employee time sheets showing McMillan’s presence at the credit union when multiple
fraudulent transactions took place and credit union records showing his employee
identification number on paperwork setting up or otherwise interacting with multiple
fraudulent accounts and transactions, all of which lined up with Bell’s detailed testimony
about McMillan’s involvement in the fraud scheme. We therefore conclude that the
Government presented substantial evidence supporting McMillan’s conviction for
conspiracy to commit bank fraud, and no manifest miscarriage of justice occurred.
Accordingly, we affirm the district court’s judgment. We dispense with oral
argument because the facts and legal contentions are adequately presented in the materials
before this court and argument would not aid the decisional process.
