Can You Go to Prison for Moving Money for Someone Else? Lessons from a $97 Million Crypto Laundering Sentence

A federal judge in Seattle sentenced a 47-year-old Washington man to five years in prison on June 9, 2026, for conspiracy to commit money laundering. He did not design the scam or pitch a single investor. What he did was open bank accounts, 81 of them across 24 financial institutions, and let $97.1 million in fraud proceeds move through them on the way to coconspirators in Nigeria and Russia. The sentencing judge said he "had every reason to know there was something wrong here."

If money has ever moved through your accounts and left you wondering where it came from, this case deserves your attention.

Geoffrey K. Auyeung opened 81 bank accounts across 24 financial institutions and routed $97.1 million in fraud proceeds to Nigeria and Russia. He was sentenced to five years in federal prison on June 9, 2026.

What Actually Happened in the Seattle Case

According to the Department of Justice press release, Geoffrey K. Auyeung was sentenced in the Western District of Washington for conspiracy to commit money laundering. The fraud ran on a believable premise: overseas coconspirators convinced investors they were buying oil tank storage capacity in Rotterdam or Houston, then renting it out at a profit. Victims wired money to what they were told were escrow accounts. Those accounts belonged to Auyeung.

He formed at least nine entities with credible energy-sector names to receive the funds. Once money landed, it moved fast: into other accounts, offshore, or into Bitcoin, Tether, USD Coin, and Ethereum through Gemini, Bitstamp, and Coinbase, with much of it forwarded to Binance accounts controlled from Nigeria and Russia. Between June 2022 and July 2024, his accounts took in $97.1 million. He was arrested in August 2024 and pleaded guilty in February 2026.

For 16 months after his indictment, Auyeung kept communicating with coconspirators and collected roughly $400,000 more in commissions by routing deposits through bank accounts in his wife's name. Homeland Security Investigations and IRS Criminal Investigation built the case. The government sought 63 months; he received 60, plus forfeiture and a restitution claim of $24.7 million.

Every transfer through Coinbase, Gemini, or Binance leaves a permanent record a subpoena can reach. The crypto leg of a laundering operation does not obscure the trail. It creates a more durable one. Blockchain tracing assembles the full picture before an arrest warrant is issued.

The Government Is Not Chasing the Fraudsters

The architects of this scheme sat in Nigeria and Russia, beyond the practical reach of a U.S. courtroom. The man who went to prison is the domestic intermediary who gave the operation its banking footprint. That is the enforcement playbook: when the principals are unreachable, the government prosecutes the person whose name is on the accounts.

The Justice Department and U.S. Attorney's Offices run a coordinated Money Mule Initiative to identify, disrupt, and prosecute people who receive and forward fraud proceeds. The Southern District of Florida is one of its most active hubs: a 15-year sentence in May 2026 for a $29 million bank impersonation laundering scheme, and April 2026 prison terms for four defendants who moved $38 million in business email compromise proceeds.

The proof in these cases is behavioral. Agents build knowledge from circumstances: account volume with no business logic, transaction descriptions that contradict the documents, commissions out of proportion to legitimate processing, and fiat converted to crypto and instantly dispersed. The crypto leg makes the government's job easier, not harder.

Your Exposure: The Statutes, the Sentencing Math, and Forfeiture

Money laundering conspiracy under 18 U.S.C. § 1956 carries up to 20 years per count. Moving more than $10,000 in criminal proceeds in a single transaction violates 18 U.S.C. § 1957, at 10 years per transaction. Transmitting money for others without licensure or registration violates 18 U.S.C. § 1960, a five-year charge prosecutors reach for when knowledge of the underlying fraud is hard to prove. Where the government contends the intermediary joined the scheme itself, wire fraud under 18 U.S.C. § 1343 adds 20 years per count.

The guidelines drive the practical numbers. Under U.S.S.G. § 2S1.1, the offense level is keyed to the value of the laundered funds, so the dollars that flowed through the accounts, not the commissions kept, set the starting point. At $97.1 million, a contested case produces a range measured in decades. Auyeung's five years reflected a guilty plea and the government's own 63-month recommendation.

Then there is the asset side. Under 18 U.S.C. § 982, Auyeung forfeited roughly $2.3 million in cash plus an Audi SQ8, and agreed not to contest the civil forfeiture of about $7.1 million seized from cryptocurrency wallets. Seizure warrants typically land at or before arrest. Anyone in this position needs a crypto seizure forfeiture lawyer's attention on the asset case as early as the criminal one.

Homeland Security Investigations and IRS Criminal Investigation built the Auyeung case. For the Southern District of Florida, the Money Mule Initiative coordinates HSI, IRS-CI, and the FBI across romance scam, business email compromise, and investment fraud enforcement, making South Florida one of the most aggressive money mule prosecution districts in the country.

The Mistakes That Turn Intermediaries Into Defendants

Talking to agents without counsel. When HSI or IRS-CI agents knock, the instinct is to explain: the money was not yours, you were just processing payments. That explanation concedes every element of the offense except knowledge, and your own account of what you noticed, and when, supplies the knowledge evidence.

Treating red flags as someone else's problem. When banks asked questions, Auyeung supplied fictitious explanations and cycled through new entities and accounts. Every workaround became proof of knowledge. If a bank closes your account or a compliance officer asks about wire activity, that is a signal to get advice, not to find a new bank.

Routing money through family. The post-indictment deposits ran through accounts in his wife's name, putting her squarely in the government's evidence. Using a relative's accounts does not insulate anyone; it manufactures a new potential defendant.

Waiting for the indictment to hire counsel. Suspicious activity reports accumulate for years, and prosecutors sort intermediaries into two piles: warning letters for those they believe acted unknowingly, indictments for those they believe knew. What your file shows when that decision gets made is the whole game.

"When the principals are unreachable, the government prosecutes the person whose name is on the accounts. That is the enforcement playbook right now."— Aaron M. Cohen, AMC Defense Law

How These Cases Actually Get Defended

The battleground is knowledge. The government must prove you knew the funds were criminal proceeds, and "should have known" only gets there through a willful blindness instruction that can be fought. A pre-indictment defense lawyer can document what innocence looks like in real time: the questions you asked counterparties, fee structures consistent with legitimate processing, the moment you stopped once suspicion crystallized.

Early intervention has a specific job here: persuading prosecutors that the client belongs in the warning-letter pile rather than the indictment pile. That can mean a presentation to the U.S. Attorney's Office before charges, a disciplined federal grand jury subpoena defense rather than panicked document production, or negotiating a resolution before the charging document fixes the dollar amounts and the narrative.

The cooperation question deserves rigor, not reflex. A proffer agreement defense lawyer weighs what the client actually knows against what the government already has, because a proffer that adds nothing buys nothing and can cost everything. Sometimes the smarter move is a reverse proffer, making the government show its cards first. A cryptocurrency fraud defense attorney who understands how exchange records and blockchain tracing get assembled can usually tell which way that decision should go.

If charges proceed, minor role arguments under U.S.S.G. § 3B1.2, contesting the funds fairly attributable to the defendant, and separating the laundering conduct from the underlying fraud still move the outcome.

Why Timing Matters Right Now

Money mule enforcement runs in coordinated annual waves, and the 2026 posture is aggressive. Romance scams, fake investment platforms, and pig butchering operations keep generating new victims, which means new intermediaries. Charging decisions are fluid early. Prosecutors deciding between a warning letter, a § 1960 count, and a § 1956 conspiracy are making judgment calls about knowledge that can be influenced while they remain open.

The Auyeung case shows the cost of letting time run: every month of activity after the first red flag added dollars to the ledger and proof to the knowledge file. By sentencing, the judge was reciting his post-indictment conduct from the bench. If a federal target letter attorney is reviewing your letter this week, or agents have already visited, options exist now that will not exist after arraignment.
