Bank-Employee Bribery After Snyder: Payments for Unauthorized Account-Opening Remain Bribes Under 18 U.S.C. § 215(a)(2), and “Accurately” Entered Fake Customer Data Is a False Bank Entry Under § 1005

Case: United States v. Diape Seck (4th Cir. Jan. 12, 2026) (unpublished)

1. Introduction

United States v. Diape Seck arises from a fraud scheme in which the Government alleged that Diape Seck, a bank employee, opened hundreds of accounts and generated debit cards for “customers” tied to a Romanian group using fabricated or unverified identity information. A jury convicted Seck after an eight-day trial of: (i) conspiracy to commit bank and wire fraud (18 U.S.C. § 1349), (ii) bank fraud and aiding and abetting (18 U.S.C. §§ 1344, 2), (iii) making false entries in bank records (18 U.S.C. § 1005), and (iv) receipt of a bribe or reward by a bank employee (18 U.S.C. § 215(a)(2)). The district court imposed 36 months’ imprisonment and restitution exceeding $1.7 million.

On appeal, Seck challenged (a) the sufficiency of the evidence across the counts and (b) the propriety of jury instructions, principally the court’s willful-blindness instruction and the elements instruction for § 1005 false entries.

The Fourth Circuit affirmed in a per curiam unpublished opinion, applying familiar sufficiency standards and concluding that the record supported the jury’s findings that Seck knowingly (or at least willfully blindly) facilitated fraudulent account openings and accepted corrupt payments for conduct outside his authorized job duties.

2. Summary of the Opinion

  • Sufficiency of evidence: The court held substantial evidence supported all convictions, emphasizing co-conspirator testimony and physical evidence (surveillance; computer/phone/personal banking records) showing Seck opened accounts for nonexistent or unverified customers, placed fraudulent signature cards into bank records, and received significant cash.
  • 18 U.S.C. § 1005 (false bank entries): The court rejected the defense theory that entries were not “false” because Seck recorded the information he was given; entering fabricated identification information for nonexistent/unverified customers can still be “false.”
  • 18 U.S.C. § 1344 (bank fraud): The court upheld convictions under the willful-blindness theory, finding evidence that Seck knew—or deliberately avoided confirming—that the accounts were being used for illegitimate purposes.
  • 18 U.S.C. § 1349 (conspiracy): The court found evidence that Seck knowingly joined and furthered the conspiracy, including improved performance metrics and an influx of cash.
  • 18 U.S.C. § 215(a)(2) (bank-employee bribery): Even assuming Snyder v. United States limits § 215 the way it limits § 666 as to gratuities, the court characterized the case as bribery: payments were made for unauthorized, prohibited conduct—opening accounts and producing debit cards for nonexistent/unverified customers.
  • Jury instructions: The court found no abuse of discretion in the willful-blindness instruction and no error in the § 1005 instruction (including materiality and intent as charged here).

The court affirmed without oral argument, concluding the record adequately supported the verdicts and the instructions were proper.

3. Analysis

A. Precedents Cited

1) Sufficiency-of-the-evidence framework

  • United States v. Freitekh, 114 F.4th 292 (4th Cir. 2024): Supplies both the standard of review (de novo for denial of acquittal) and the “heavy burden”/“rare case” rhetoric. The Seck panel uses Freitekh to frame the high deference owed to the jury when evidence is viewed in the Government’s favor.
  • United States v. Henderson, 107 F.4th 287 (4th Cir.), cert. denied, 145 S. Ct. 578 (2024): Provides the definition of “substantial evidence” as evidence adequate for a reasonable factfinder to find guilt beyond a reasonable doubt. The Seck panel leverages this to emphasize that appellate courts do not reweigh credibility.
  • United States v. Rafiekian, 991 F.3d 529 (4th Cir. 2021): Reinforces that direct and circumstantial evidence (and reasonable inferences) can sustain a verdict. This matters in Seck because knowledge and intent were largely proven circumstantially (pattern of account openings, concealment-like conduct, cash).

2) 18 U.S.C. § 1005 (false entries) and materiality

  • United States v. Gregory, 54 F.4th 1183 (10th Cir. 2022): The panel borrows a clear elements formulation for § 1005 (false entry; knowledge of falsity; intent to injure or deceive). Although not binding, it provides an accessible structure for evaluating Seck’s arguments.
  • United States v. Christy, 916 F.3d 814 (10th Cir. 2019): Cited for the proposition that § 1005 does not expressly include materiality, while also supplying a standard definition of materiality (natural tendency/capable of influencing). The Seck panel notes the district court nonetheless instructed on materiality—important because the Fourth Circuit then evaluates the charge “as given,” and finds it accurate.

3) 18 U.S.C. § 1344 (bank fraud) and willful blindness

  • United States v. Adepoju, 756 F.3d 250 (4th Cir. 2014): Provides the subsection distinction between § 1344(1) and § 1344(2) and the elements for each. The panel uses Adepoju to situate the bank-fraud analysis and to explain why intent-to-defraud and knowing execution are central.
  • United States v. Oloyede, 933 F.3d 302 (4th Cir. 2019): Serves as the anchor for the willful-blindness doctrine: the two requirements (subjective belief in a high probability + deliberate steps to avoid learning the truth) and the cautionary note about when such instructions are appropriate. Seck relies on a claimed lack of knowledge, and the panel, invoking Oloyede, holds the instruction fit the evidentiary record.

4) 18 U.S.C. § 1349 (conspiracy) proof and inferences

  • United States v. Burfoot, 899 F.3d 326 (4th Cir. 2018): Quoted for the elements of wire-fraud conspiracy under § 1349 and the requirement of willful joining with intent to further the unlawful purpose.
  • United States v. Vinson, 852 F.3d 333 (4th Cir. 2017): Cited both for bank-fraud conspiracy under § 1349 and for the appellate standard on willful-blindness instructions (abuse of discretion). This dual role reflects that Seck’s appeal attacked both substantive sufficiency and jury-instruction choices.
  • United States v. Watkins, 111 F.4th 300 (4th Cir. 2024): Supports the proposition that knowledge/intent are often proven circumstantially and lists the kinds of circumstantial evidence from which a jury may infer knowledge of a conspiracy (relationships, length of association, conduct, nature of conspiracy). The Seck panel uses this to validate inferences drawn from Seck’s sustained, high-volume participation.

5) 18 U.S.C. § 215(a)(2) (bank-employee bribery) and the bribe/gratuity distinction

  • United States v. Calk, 87 F.4th 164 (2d Cir. 2023), cert. denied, 145 S. Ct. 144 (2024): Provides a textual paraphrase of § 215(a)(2) and a definition of “corruptly” as acting with a bad purpose to accomplish an unlawful end (or lawful end by unlawful means). The Seck panel uses Calk to frame the mens rea and “corruptly” requirement.
  • Snyder v. United States, 603 U.S. 1 (2024): Addressed 18 U.S.C. § 666 and held that statute does not criminalize after-the-fact gratuities (as opposed to bribes promised/given before an act). Seck attempted to import Snyder to § 215(a)(2). The panel assumed arguendo that Snyder could apply, but distinguished the facts as bribery: payments were for prohibited conduct, not mere “tips” for legitimate services.

B. Legal Reasoning

1) The court’s unifying theme: knowledge can be proven by patterns, incentives, and deliberate ignorance

Across the counts, the Fourth Circuit treated Seck’s core defense—lack of specific knowledge about the Romanian customers’ downstream fraud—as legally insufficient to defeat the mens rea elements where the evidence showed he knowingly created false account-opening records for nonexistent or unverified persons, and where he received cash in exchange.

2) § 1005: “False entry” includes entering fabricated identity information, even if transcribed accurately

Seck argued the entries were not “false” because he entered the information presented to him. The panel rejected that move: the falsity inhered in the fact that the accounts were opened for nonexistent or unverified customers and supported by fraudulent signature cards—so the bank’s records were false in substance, not merely in transcription. The opinion also separated falsity from later account use: the Government’s theory was not “the customers later committed fraud, therefore the entries were false,” but rather “the entries were false at creation.”

On intent, the court held Seck did not need to know the “specifics” of the customers’ unlawful activities to intend to injure or deceive the bank; it was enough that he knew he was placing fraudulent account-opening documentation into bank records.

3) § 1344 bank fraud: willful blindness bridges claimed ignorance when the record shows deliberate avoidance

The panel upheld the bank-fraud convictions under a knowledge theory that included willful blindness. Applying Oloyede, the court found evidence supporting (i) Seck’s subjective awareness of a high probability of illegitimacy (e.g., the high volume of accounts, fake identification information obtained online) and (ii) his deliberate participation despite warning signs.

The opinion also addressed and discounted Seck’s “I reported concerns to management” argument. The court treated those reports as vague, sporadic, and materially incomplete—especially given what Seck did not report (opening accounts for nonexistent/unverified persons, receiving IDs digitally, accepting cash). In the panel’s view, these omissions supported the inference that the “reports” were not genuine compliance efforts capable of negating intent.

4) § 1349 conspiracy: sustained participation + benefits received supported an agreement and intent to further

For the conspiracy conviction, the Fourth Circuit emphasized that a jury can infer knowledge and agreement from circumstantial evidence, especially where the defendant’s association is prolonged and operationally significant. The court pointed to two types of “benefit” evidence: (i) performance numbers improving due to high account volume and (ii) a substantial influx of cash. Combined with co-conspirator testimony that Seck agreed to open fraudulent accounts in exchange for cash, the panel found the agreement and intent elements satisfied.

5) § 215(a)(2) after Snyder: even if gratuities are excluded, payments for prohibited conduct are bribery

Seck’s most doctrinally ambitious argument was that Snyder’s bribe-versus-gratuity limitation (announced for § 666) should apply to § 215, recasting his payments as after-the-fact tips. The panel avoided a definitive extension holding by assuming arguendo that Snyder could apply, then rejecting Seck’s characterization on the facts: he was paid to do what he was not permitted to do—open accounts and create debit cards for nonexistent or unverified customers. That framing makes the payments “corrupt” under § 215 because they induced (or rewarded) unauthorized conduct, i.e., an unlawful end or an unlawful means under Calk’s definition of “corruptly.”

6) Jury instructions: willful blindness warranted; § 1005 instruction not erroneous

The court reiterated that willful-blindness instructions must be used cautiously, but are proper when a defendant claims lack of guilty knowledge in the face of evidence of deliberate ignorance. Given the evidence, the panel found no abuse of discretion. It also upheld the § 1005 instruction, including the way materiality and intent were described in this case, and noted the district court permitted counsel to address any confusion in closing.

C. Impact

  1. Practical boundary for “tip” defenses under § 215(a)(2): Even if future Fourth Circuit panels were to adopt Snyder-style limits for § 215, Seck signals that payments tied to unauthorized banking conduct (e.g., onboarding nonexistent/unverified customers, manufacturing access devices) will be treated as bribes, not benign gratuities. The key factual pivot is whether the employee was paid for legitimate services versus paid to violate institutional rules/law.
  2. § 1005 “false entry” theories remain robust: The opinion reinforces a substance-over-form approach: a bank record can be “false” even if it precisely reproduces the false identity information supplied by a customer, where the falsity concerns the reality/verification of the customer and the authenticity of account-opening documentation.
  3. Compliance “paper trails” may not negate intent if incomplete or strategic: The court’s treatment of Seck’s sporadic reports suggests that half-measures—raising generic volume concerns while omitting the core improprieties— can be viewed as consistent with willful blindness or concealment, rather than as exculpatory transparency.
  4. Willful blindness remains a powerful prosecution tool in financial-institution cases: When the defendant occupies a gatekeeping role (like account opening), the combination of red flags, unusual volume, procedural deviations, and financial benefits can support both a willful-blindness instruction and a jury finding of knowledge.

Important limitation: The opinion is unpublished and expressly “not binding precedent” in the Fourth Circuit. Its influence will therefore be primarily persuasive (particularly fact-pattern guidance for district courts), rather than controlling circuit law.

4. Complex Concepts Simplified

Substantial evidence (appellate review)
On appeal, the question is not whether judges believe the defendant is guilty; it is whether a reasonable jury could find guilt beyond a reasonable doubt when viewing the evidence in the Government’s favor.
Willful blindness (deliberate ignorance)
A defendant cannot avoid “knowledge” by intentionally not asking questions or by avoiding confirmation of obvious facts. The doctrine requires: (1) the defendant believed there was a high probability the fact was true, and (2) the defendant deliberately avoided learning the truth.
False bank entry (§ 1005)
A “false entry” is not limited to typing an incorrect number. It can include entering customer/account information that is fictitious in substance— such as records implying a real, verified customer exists when the account was actually opened for a nonexistent or unverified person.
Bribe vs. gratuity
A bribe is tied to influencing or rewarding a person for acting in a corrupt or unauthorized way (often connected to an exchange). A gratuity is more like a thank-you gift given after the fact without an agreement to influence. Seck holds that paying a bank employee to do something he is not permitted to do is bribery on these facts, even if the payment is styled as a “tip.”

5. Conclusion

United States v. Diape Seck affirms a multi-count fraud and bribery prosecution against a bank employee by emphasizing three propositions: (1) bank-record falsity under § 1005 turns on substantive truthfulness, not whether the employee faithfully transcribed fabricated data; (2) willful blindness can satisfy “knowledge” for bank fraud and conspiracy when red flags are abundant and the defendant benefits from continued participation; and (3) even in the shadow of Snyder, payments to a bank employee for unauthorized account-opening conduct are readily treated as bribes under § 215(a)(2). Although unpublished, the decision offers a clear, fact-driven roadmap for how federal courts may analyze gatekeeper misconduct in high-volume account opening schemes and how they may cabin “gratuity” arguments when the paid conduct itself is prohibited.
