Overlapping Evidence May Support a Willful-Blindness Instruction in Money-Laundering Conspiracies, and Guidelines Errors Are Harmless Where the Court Would Impose the Same Sentence

1. Introduction

United States v. Sepetu addresses how juries may infer knowledge in a money-laundering conspiracy built largely on circumstantial evidence, and how appellate courts treat claimed instructional error and alleged sentencing-guideline miscalculations. Defendants-Appellants Nafis Quaye and Sunna Sepetu were convicted after a joint trial in the District of New Hampshire of conspiracy to commit money laundering in violation of 18 U.S.C. § 1956(h) and 18 U.S.C. § 1956(a)(1)(B)(i).

The government’s theory was that Quaye operated a years-long scheme using friends and family as “owners” of business entities and bank accounts, moving large wire transfers quickly through those accounts and withdrawing significant cash, all while maintaining scant business records. Sepetu—romantically involved with Quaye—registered and ran bank accounts for “Logitech” (initially “Easy Soft”), received substantial funds, and wired money onward at Quaye’s direction.

The funds largely came from Maryann Schirmer, who was victimized by a romance scam (perpetrated by someone posing as “Shawn Walker”). Crucially, there was no direct proof that Quaye or Sepetu were part of the romance scam itself; the core dispute was whether they nonetheless knew, or were willfully blind to the fact, that the wired funds were criminal proceeds and that the transactions were designed to conceal their source.

On appeal, Defendants challenged (i) the sufficiency of the evidence; (ii) the giving of a willful blindness instruction; and (iii) the denial of their requested good faith instruction. Sepetu additionally challenged (iv) the government’s collective references to “the defendants” as guilt-by-association and (v) the calculation of her Guidelines range.

2. Summary of the Opinion

The First Circuit affirmed both convictions and Sepetu’s sentence. It held that the circumstantial record—repeated high-dollar wires from a single U.S. individual account, use of straw “owners,” rapid movement of funds, large cash withdrawals, personal spending inconsistent with a legitimate low-margin export business, shifting explanations to investigators, lack of paperwork typical of export transactions, and continued activity after bank/law-enforcement inquiries—was sufficient for a rational jury to find actual knowledge or willful blindness.

The court also upheld the district court’s willful blindness instruction, rejecting the claim that it impermissibly allowed conviction on negligence or “should have known” reasoning. It further held that no separate good faith instruction in Defendants’ preferred phrasing was required because the charge as a whole correctly and clearly conveyed the government’s burden to prove specific intent and even referenced “good faith.”

As to Sepetu’s claim that the prosecutor’s “defendants” rhetoric invited guilt-by-association, the panel found no plain error, emphasizing that evidence of Sepetu’s own conduct supported her conviction and that the district judge gave strong individualized-guilt instructions.

Finally, the court declined to decide whether the district court erred in finding “substantial financial hardship” for Guidelines purposes, concluding that any error was harmless because the sentencing judge made clear the same sentence would be imposed regardless of the Guidelines calculation and then varied dramatically downward to 12 months and one day.

3. Analysis

3.1. Precedents Cited

A. Sufficiency of the Evidence and Rule 29 Review

• United States v. Pérez-Greaux — The court reiterated de novo review of Rule 29 denials and the obligation to view evidence in the light most favorable to the government, credit government witnesses, draw reasonable inferences for the verdict, and avoid reweighing credibility. This set the high bar Defendants faced on sufficiency.
• United States v. Bobadilla-Pagán — Quoted via Pérez-Greaux for the “plausible rendition of the record” formulation, underscoring that appellate review is not a retrial.
• United States v. Coleman and United States v. Morillo — Used for the “equal or nearly equal circumstantial support” principle: if evidence supports guilt and innocence equally, reversal is required. The panel concluded the record was not in equipoise.
• United States v. Burgos, Morgan v. Dickhaut, and Leftwich v. Maloney — Cited for caution against unreasonable inferences and “stack[ing] inference upon inference.” The court framed its affirmance as rooted in multiple concrete “red flags,” not speculation.

B. Elements of Conspiracy and Knowledge (Actual Knowledge vs. Willful Blindness)

• United States v. Burgos — Supplied the conspiracy elements and expressly recognized that “knowledge” may be proven by actual knowledge or willful blindness. It also provided the definitional language for willful blindness (“consciously and deliberately avoided learning”).
• United States v. Dellosantos — Quoted through Burgos for the basic conspiracy framework.
• United States v. Lizardo — Cited (via Burgos) for the willful blindness definition.
• United States v. Azubike — Central to the willful blindness instruction analysis. The panel applied its three-part test for when such an instruction is appropriate and emphasized that “warning signs” can suffice; direct evidence of deliberate ignorance is not required.

C. Money Laundering Knowledge and “Specified Unlawful Activity” Precision

• United States v. Frigerio-Migiano — Provided the underlying money-laundering knowledge requirements: the defendant must know the funds are proceeds of “some unlawful activity” and that the transaction is designed to conceal aspects of the proceeds.
• United States v. Cedeno-Perez — Used to reject any suggestion that the government must prove the defendant knew the precise criminal predicate; it is enough to know the funds derive from some felony.

D. “Red Flags” and Patterns as Circumstantial Proof

• United States v. Adorno-Molina and United States v. Rivera-Rodriguez — Both supported the proposition that straw ownership, concealment, frequent transfers, and patterns of unusual financial behavior can allow juries to infer laundering knowledge or willful blindness.
• United States v. Flores — Cited for the evidentiary significance of missing invoices and documentation as a marker of illegitimacy (notably, a Third Circuit reference used for a commonsense inference).
• United States v. Singh — Provided the “inquiry notice” concept: warning signs plus a claimed lack of knowledge can justify finding deliberate eye-closing.
• United States v. Corchado-Peralta — Supported the inference of illicit origin where spending vastly exceeds legitimate income and lawful sources are not obvious.
• United States v. Abbas and United States v. Rivera-Izquierdo — Used to show that continuing to receive suspicious wires after being warned by bank investigators can support an inference of knowledge of criminal nature.

E. Instructional Challenges: Standards and Substantive Requirements

• United States v. Evans — Acknowledged the First Circuit’s inconsistency on the standard of review for preserved willful blindness instruction challenges (de novo vs. abuse of discretion), while finding affirmance warranted under either.
• United States v. Figueroa-Lugo — Supplied de novo review for refusals to give requested instructions.
• United States v. Dockray — Key for good faith: even if good faith is a complete defense, the court need only convey the substance; no right to particular phrasing; and a separate good faith instruction is unnecessary where intent is properly charged.
• United States v. González-Pérez and United States v. González-Soberal — Provided the three-part reversible-error test for refusing requested instructions.
• United States v. De La Cruz — Quoted for the “substantial prejudice” requirement.
• United States v. Goodspeed — Reinforced that the First Circuit does not require a separate good faith instruction if the intent instruction is clear and accurate.
• United States v. Arcadipane — Used to confirm that explicit intent instructions, and even a non-identical mention of good faith, can suffice.

F. Prosecutorial Argument and “Guilt by Association”

• United States v. Wilkerson — Provided the plain-error framework for unpreserved misconduct arguments.
• United States v. Dworken and United States v. Allen — Recognized the danger of guilt by association in joint trials and the limits on argument that effectively convicts one defendant based on another’s wrongdoing.
• United States v. Lebron-Gonzalez and Opper v. United States — Supported the curative role of cautionary instructions.
• United States v. Canty and United States v. Ayala-Garcia — Distinguished as more severe/profound prosecutorial misconduct contexts than the collective “defendants” references here.

G. Sentencing Procedure, Guidelines Error, and Harmlessness

• United States v. Delgado and United States v. Contreras-Delgado — Provided the procedural-reasonableness framework and the notion that relying on clearly erroneous facts can be procedural error.
• Gall v. United States — Cited for the general sentencing framework, including procedural error categories.
• United States v. Romero-Carrion and United States v. Noone — Supplied the “highly probable” harmless-error formulation.
• United States v. Rivera and United States v. Ouellette — Controlled the disposition: where the sentencing court clearly states it would impose the same sentence regardless of the Guidelines, calculation errors are harmless.

3.2. Legal Reasoning

A. Sufficiency: Knowledge and Intent Can Be Proven Without a Direct Link to the Predicate Fraud

The opinion’s core move is separating (1) participation in the underlying romance scam from (2) knowledge that incoming funds were criminal proceeds and that the financial transactions were designed to conceal. The panel treated the absence of direct evidence tying Defendants to “Ansah’s” romance scam as non-dispositive because money laundering conspiracy does not require knowing the exact predicate or personally committing it; knowledge can be inferred from the laundering mechanics and surrounding circumstances.

The court emphasized multiple, mutually reinforcing indicators:

• Structural concealment: repeated use of friends/family to form entities and open accounts, with Quaye directing operations behind the scenes.
• Transaction pattern: large wires in, rapid wires out, and substantial cash withdrawals—consistent with layering and distancing funds from their source.
• Source irregularities visible on the wires: the wires showed origin from a U.S.-based personal account (Maryann K Schirmer) and were often labeled “investment,” inconsistent with the purported Ghana export-customer narrative.
• Absence of ordinary trade documentation: no meaningful titles, bills of lading, bills of sale, or consistent invoices; Sepetu produced only three invoices, none referencing Defendants’ entities.
• Personal spending and “thin profits” story mismatch: luxury/club/retail travel expenditures and large cash withdrawals inconsistent with a legitimate, low-margin shipping/export operation.
• Shifting explanations: inconsistent accounts about who ran what (e.g., who was “in charge” of Logitech/La Vita) and what the businesses did.
• Persistence after warnings: continued activity after a bank compliance inquiry (Quaye) and after law enforcement asked Sepetu whether anything illegal was happening.

The court treated these as more than “should have known” indicators: they were red flags strong enough to permit either actual-knowledge or deliberate-avoidance findings.

B. Willful Blindness: The Instruction Was Proper Even If the Same Evidence Also Supports Actual Knowledge

The panel applied the United States v. Azubike three-factor test and focused on the second element: whether facts suggest a conscious course of deliberate ignorance. It concluded the instruction’s language repeatedly required deliberateness (“deliberately closed his or her eyes,” “consciously and deliberately avoided learning,” “willfully made himself or herself blind”) and explicitly excluded “mere negligence or mistake.”

A particularly consequential clarification is the court’s rejection of the argument that a willful-blindness instruction becomes improper merely because the government also argues actual knowledge from overlapping facts. The panel stated it has “never indicated” that the evidentiary set for willful blindness must be distinct from that supporting actual knowledge, or that the sets cannot overlap entirely. Practically, this reduces defendants’ ability to defeat a willful blindness instruction by characterizing the government’s case as “all-or-nothing” actual knowledge.

C. Good Faith: No Right to Preferred “Complete Defense” Language When Intent Is Correctly Charged

Defendants wanted a more emphatic good-faith instruction (including “good faith ... is a complete defense”). The First Circuit held the district court’s charge substantially covered the point by:

• requiring proof beyond a reasonable doubt of knowing, willful, intentional joining of the conspiracy;
• stating that accident, mistake, or misunderstanding negates the required intent; and
• explicitly telling jurors that reasonable doubt about “criminal intent as opposed to acting in good faith” requires acquittal.

Under United States v. Dockray and United States v. Goodspeed, that was enough; the law does not demand a separate, specially worded instruction when the “opposite of good faith”—specific criminal intent—is clearly and accurately explained.

D. Joint-Trial Advocacy: Collective “Defendants” References Were Not Plain Error Given the Evidence and Curative Instructions

Sepetu’s mismatch argument—Quaye’s broader involvement across multiple accounts versus her ties mainly to Logitech—was acknowledged but did not carry the day. The panel found that the prosecutor’s collective framing tracked shared themes supported by evidence as to both (incoming Schirmer funds, rapid onward transfers, personal expenditures, knowledge of Schirmer’s name on transfers).

Critically, the district court instructed jurors that guilt is “personal and individual” and that each defendant’s case “stands or fails” on proof against that defendant alone, invoking the curative principles emphasized in United States v. Lebron-Gonzalez and Opper v. United States. Under plain-error review (United States v. Wilkerson), the panel found no clear or obvious error undermining fairness.

E. Sentencing: Even if the “Substantial Financial Hardship” Finding Was Wrong, the Error Was Harmless

Sepetu challenged the application of a two-level enhancement under U.S.S.G. § 2B1.1(b)(2)(A) and the denial of a reduction under U.S.S.G. § 4C1.1(a), both turning on whether she “personally caused substantial financial hardship.” The court did not resolve the factual dispute about Schirmer’s alleged tax penalty and its cause.

Instead, relying on United States v. Rivera (quoting United States v. Ouellette), it held any Guidelines error harmless because the district judge repeatedly stated the Guidelines calculations would not affect the actual sentence and imposed a dramatic downward variance (12 months and one day). The holding underscores a pragmatic appellate rule: explicit “same sentence regardless” statements can insulate Guidelines disputes from reversal.

3.3. Impact

• Willful blindness instructions will be harder to defeat in laundering cases built on circumstantial “red flags.” The opinion reinforces that deliberate ignorance can be inferred from a defendant’s failure to investigate obvious anomalies (e.g., repeated high-dollar “investment” wires from a single personal U.S. account) combined with evasive conduct, missing records, and continued operations after warnings.
• Prosecutors may plead and argue actual knowledge and willful blindness in the alternative without risking reversible error from evidentiary overlap. The court’s explicit acceptance of overlap reduces a common defense contention that the instruction is improper unless the evidence uniquely supports willful blindness.
• Trial courts in the First Circuit retain broad discretion in phrasing “good faith” concepts as long as intent is clearly charged. Litigants should expect that requests for “complete defense” language may be denied without error if the instructions already communicate that good faith (or lack of criminal intent) requires acquittal.
• Joint-trial rhetoric disputes will often be resolved by individualized-guilt jury instructions—especially on plain-error review. Defendants should preserve objections contemporaneously to avoid the steep Wilkerson plain-error hurdle.
• Sentencing appeals that hinge on Guidelines disputes face a significant harmless-error barrier when the judge clearly announces an identical alternative sentence. The decision further incentivizes district courts to create a robust “alternative sentence” record to protect sentences on appeal.

4. Complex Concepts Simplified

• Money laundering under 18 U.S.C. § 1956(a)(1)(B)(i): Conducting a financial transaction with proceeds of unlawful activity, knowing the money is criminal proceeds, and knowing the transaction is designed (at least in part) to conceal the money’s nature, source, ownership, or control.
• Money laundering conspiracy under 18 U.S.C. § 1956(h): An agreement to commit money laundering; the government must prove the agreement, the defendant’s knowledge of it (actual or willfully blind), and voluntary participation with intent to further its unlawful objective.
• Willful blindness: A substitute for actual knowledge when a defendant suspects a fact (high probability) but deliberately avoids confirming it. It is not negligence; it requires conscious avoidance.
• Rule 29 sufficiency review: After conviction, the question is not whether the appellate court is persuaded of guilt, but whether a rational jury could find guilt beyond a reasonable doubt when evidence is viewed most favorably to the government.
• Good faith defense (as used here): Not a separate element the defendant must prove; rather, it negates the required criminal intent. If the jury has reasonable doubt whether the defendant acted with criminal intent versus good faith, it must acquit.
• Plain error: A demanding appellate standard for unpreserved objections: the defendant must show a clear/obvious error that affected substantial rights and seriously harmed the integrity of proceedings.
• Guidelines “harmless error” via an alternative sentence: Even if the Guidelines were miscalculated, the sentence can be affirmed if the judge clearly indicates the same sentence would be imposed regardless of the correct range.

5. Conclusion

United States v. Sepetu affirms money-laundering conspiracy convictions grounded in a dense web of circumstantial indicators—transaction patterns, visible inconsistencies in wire origins and labels, lack of ordinary business documentation, personal spending, inconsistent explanations, and continued conduct after warnings. It strengthens two practical doctrinal points in the First Circuit: (1) willful blindness instructions remain appropriate where red flags go uninvestigated, even if the same evidence could also support actual knowledge; and (2) defendants are not entitled to bespoke “good faith” phrasing when the charge as a whole accurately and clearly requires proof of specific intent and explains that good faith (lack of criminal intent) requires acquittal. On sentencing, the decision underscores that explicit “same sentence regardless of the Guidelines” findings can render Guidelines disputes harmless on appeal.
