Money Laundering Federal Prosecution in Louisiana: BSA Violations, Structuring, and EDLA Cases

Federal money laundering prosecutions in the Eastern District of Louisiana arise across a wide range of underlying criminal activity: drug trafficking organizations, public corruption schemes, health care fraud, and international financial crime all generate proceeds that defendants attempt to conceal or legitimize. The statutory framework — anchored by 18 U.S.C. § 1956, § 1957, and the Bank Secrecy Act — is broad, and the penalties are severe. Understanding how EDLA prosecutors approach money laundering cases, and what defenses are available, is essential for any defendant facing these charges.

The Two Principal Money Laundering Statutes: 18 U.S.C. §§ 1956 and 1957

Section 1956 is the core federal money laundering statute. It criminalizes three distinct categories of conduct: (1) conducting a financial transaction involving proceeds of a specified unlawful activity (SUA) with the intent to promote the underlying crime, or knowing the transaction is designed to conceal the proceeds; (2) transporting monetary instruments or funds in international or domestic interstate commerce knowing the funds derive from an SUA and intending to promote the SUA or conceal the funds; and (3) conducting or attempting to conduct a financial transaction involving funds represented by law enforcement to be proceeds of an SUA (the "sting" provision). The knowledge and intent elements are critical — the government must prove the defendant knew both that the funds derived from criminal activity and the specific intent that applies to the charged variant of the statute.

Section 1957 is narrower but operationally important: it criminalizes knowingly engaging in a monetary transaction of more than $10,000 in proceeds of an SUA, without requiring proof of intent to conceal or promote. Because § 1957 lacks the intent-to-conceal element, it is often easier for prosecutors to prove — but the $10,000 threshold and the requirement that the transaction occur through a financial institution limit its scope compared to § 1956.

Specified Unlawful Activities: What Predicate Offenses Trigger Money Laundering Charges

Money laundering requires that the funds constitute proceeds of a "specified unlawful activity" (SUA). The SUA list in § 1956(c)(7) is extensive and includes drug trafficking, wire fraud, mail fraud, bank fraud, bribery, RICO violations, health care fraud, foreign corruption offenses, and many others. In EDLA, drug trafficking proceeds are the most common predicate, but public corruption and health care fraud cases frequently generate money laundering charges as well. The government need not secure a conviction for the underlying SUA before charging money laundering — it must establish that the SUA occurred as an element of the money laundering charge, but the two cases can be tried simultaneously.

BSA Reporting Requirements and Structuring

The Bank Secrecy Act (BSA) requires financial institutions to file Currency Transaction Reports (CTRs) for cash transactions exceeding $10,000, and Suspicious Activity Reports (SARs) for transactions that appear suspicious. Structuring — breaking up cash deposits or withdrawals into amounts below the $10,000 CTR threshold in order to avoid BSA reporting — is itself a federal crime under 31 U.S.C. § 5324, regardless of whether the underlying funds are criminal proceeds. The Supreme Court addressed structuring in Ratzlaf v. United States (1994), holding that the government must prove the defendant knew structuring was illegal, not merely that the defendant was aware of the reporting requirement. Congress subsequently amended the statute to eliminate the willfulness element for certain structuring offenses. In EDLA practice, structuring charges frequently accompany drug trafficking or fraud prosecutions as a way to add charges for each individual transaction.

The Willful Blindness Doctrine in Money Laundering Cases

Knowledge that funds are criminally derived can be proven through direct evidence or circumstantially through the doctrine of willful blindness (sometimes called "deliberate ignorance"). Under willful blindness, the government can satisfy the knowledge element by showing that the defendant was aware of a high probability that the funds were criminal proceeds and deliberately avoided learning the truth. The Fifth Circuit has approved willful blindness jury instructions in money laundering cases. Defense counsel frequently challenge willful blindness instructions as amounting to a constructive knowledge standard that is inconsistent with the statutory requirement of actual knowledge.

Merger Issues: When the Laundering Charge Duplicates the Underlying Offense

Courts have wrestled with the merger problem in money laundering cases: if the underlying offense and the money laundering charge arise from the same transaction, using the same proceeds, the risk exists that prosecutors are simply doubling penalties for a single course of conduct. The Fifth Circuit has addressed merger in § 1956 cases, holding that the government must identify a financial transaction that is distinct from the underlying offense. In drug trafficking cases, for example, the use of drug proceeds to purchase additional drugs for distribution can satisfy the promotion prong of § 1956 as a distinct act. Defense counsel should examine whether the alleged money laundering transaction is sufficiently independent from the SUA to avoid merger.

OFAC and International Dimensions of Money Laundering Prosecutions

In cases involving international financial flows — including transactions through foreign correspondent banks, trade-based money laundering, or proceeds from sanctioned jurisdictions — EDLA prosecutions may intersect with OFAC enforcement. The Office of Foreign Assets Control (OFAC) maintains a separate civil and criminal enforcement regime for sanctions violations, and transactions involving sanctioned parties or jurisdictions can form the predicate for money laundering charges as well as independent OFAC violations. Where international dimensions exist, federal defense counsel must coordinate with specialists in sanctions law, as the two enforcement regimes have different standards of proof, different administrative processes, and different resolution pathways.

Sentencing Exposure in Federal Money Laundering Cases

Section 1956 carries a maximum penalty of 20 years imprisonment per count. Section 1957 carries a maximum of 10 years. In practice, Guidelines calculations are driven primarily by the amount of laundered funds — an offense involving more than $550 million, for example, carries an 18-point offense level enhancement. Money laundering counts often run consecutively to drug trafficking or fraud sentences, dramatically increasing total exposure. The presence of a money laundering charge also affects the forfeiture analysis: the government can pursue forfeiture of all property involved in or traceable to money laundering transactions, which can include legitimately acquired assets that were commingled with criminal proceeds.
