A 22-year-old from Newport Beach, California, will spend nearly six years in federal prison for his role in a sprawling cryptocurrency theft ring that stole more than $263 million and blew the proceeds on Lamborghinis, half-million-dollar nightclub tabs, and mansions worth up to $9 million.
U.S. District Court Judge Colleen Kollar-Kotelly sentenced Evan Tangeman on Friday to 70 months behind bars, plus three years of supervised release, for participating in a RICO conspiracy that federal prosecutors described as an enterprise "built on greed so brazen it borders on the cartoonish."
The sentence, announced by the U.S. Attorney's Office for the District of Columbia, marks the ninth guilty plea to come out of the investigation, a signal that federal law enforcement is methodically dismantling a criminal network that stretched across at least four states and overseas.
The enterprise began no later than October 2023 and ran through at least May 2025. Its members, many of them under 20 years old, used social engineering tactics to steal cryptocurrency on a massive scale. Tangeman's job was the back end: converting stolen digital currency into fiat cash and helping the group spend it as fast as it came in.
He admitted to laundering at least $3.5 million for members of the ring. He worked with real estate agents in Los Angeles to secure large mansions and arranged rental homes in Miami and the Hamptons that ran $40,000 to $80,000 per month. Some of those properties were valued between $4 million and nearly $9 million.
The spending didn't stop at real estate. The group amassed a fleet of exotic cars valued from $100,000 to $3.8 million apiece. Co-defendant Malone Lam arranged the purchase of a widebody Lamborghini Urus for Tangeman personally. Luxury watches ran between $100,000 and more than $500,000. Handbags and clothing cost tens of thousands of dollars. Nightclub tabs hit $500,000 in a single evening.
That's a lot of conspicuous consumption for a crew of teenagers and twenty-somethings with no visible legitimate income.
What elevated Tangeman's conduct beyond garden-variety money laundering, prosecutors said, was what he did after law enforcement closed in. When co-defendants Malone Lam and Jeandiel Serrano were among the first members arrested, Tangeman didn't cooperate. He directed another co-defendant, Tucker Desmond, to destroy digital devices belonging to members of the enterprise.
U.S. Attorney Jeanine Ferris Pirro did not mince words about what that meant. In a statement accompanying the sentencing, she said:
"But Evan Tangeman didn't just launder the money that fueled that lifestyle. When his co-conspirators were arrested, he moved to destroy the evidence. That is consciousness of guilt, and this office and the court have treated that accordingly."
Law enforcement eventually executed a search warrant on Tangeman's residence and identified and seized additional vehicles, including a black 2022 Rolls Royce Ghost valued at more than $300,000 and a white and black Porsche GT3 RS.
Tangeman pleaded guilty on December 8, 2025, before Judge Kollar-Kotelly. The case number is 24cr417.
The investigation involved a wide constellation of federal agencies. The FBI's Washington Field Office and IRS-Criminal Investigation's Washington, D.C., Field Office led the probe. The FBI's Los Angeles and Miami field offices provided significant support, as did U.S. Attorney's Offices in the Central District of California, the Southern District of Florida, and the District of New Jersey.
Assistant U.S. Attorney Will Hart, of the Fraud, Public Corruption, and Civil Rights Section of the D.C. U.S. Attorney's Office, is prosecuting the matter. Former Assistant U.S. Attorney Kevin Rosenberg also provided assistance.
The multi-district, multi-agency coordination reflects a Department of Justice that, at least in this case, is treating crypto-enabled theft with the seriousness it deserves. The DOJ's recent launch of a dedicated fraud division targeting vulnerable taxpayer programs suggests this kind of aggressive posture may become more common, not less.
Nine guilty pleas from a single investigation is a meaningful number. It means cooperators are flipping, evidence is stacking up, and the remaining defendants, Lam, Serrano, and Desmond among them, face mounting pressure. Their procedural status was not detailed in the announcement, but the trajectory is clear.
Lost in the spectacle of $3.8 million sports cars and $500,000 watch collections are the people who actually owned the $263 million in cryptocurrency before this crew stole it. The DOJ press release does not name the victims or describe how the social engineering attacks targeted them. But the scale, a quarter of a billion dollars, suggests the damage was not limited to a handful of marks.
Cryptocurrency holders are often dismissed by critics as speculators who should have known the risks. But theft is theft. Social engineering, tricking people into surrendering access to their accounts, is fraud, plain and simple. The victims here were not gambling. They were robbed.
The case also underscores a persistent vulnerability in the digital economy. When a group of teenagers can orchestrate a $263 million heist from locations scattered across California, Connecticut, New York, Florida, and abroad, it raises hard questions about the security infrastructure that crypto platforms and financial institutions provide to their users. The FBI has shown it can pursue complex cases across borders when it commits the resources. The question is whether enforcement can keep pace with the speed of digital crime.
One of the most striking details in the case is the age of the conspirators. The DOJ noted that members of the enterprise were "often under 20 years old." Tangeman himself is just 22. These were not hardened career criminals. They were young people who apparently decided that stealing hundreds of millions of dollars and living like rap-video extras was a viable career plan.
The group moved from Los Angeles to Miami in September 2024, renting homes and accumulating vehicles at a pace that should have raised red flags with every landlord, dealer, and nightclub owner who took their money. The fact that it didn't, or that no one cared enough to ask, speaks to the broader culture of willful blindness that enables money laundering in the first place.
Pirro framed the enterprise in memorable terms:
"This criminal enterprise was built on greed so brazen it borders on the cartoonish. They stole millions, spent it on half-million-dollar nightclub tabs, Lamborghinis, and Rolexes."
Cartoonish is the right word. But the consequences are real, for the victims who lost their savings, and now for Tangeman, who will spend his mid-twenties in a federal prison cell. The DOJ's willingness to pursue high-profile cases aggressively is encouraging, provided it extends beyond press releases to sustained institutional commitment.
Several important details remain unclear. The DOJ has not publicly described the specific social engineering methods used to steal the cryptocurrency. It has not disclosed the identities of the victims or whether restitution will be ordered. The procedural status of co-defendants Lam, Serrano, and Desmond, whether they have entered pleas, are cooperating, or are headed to trial, was not addressed in the announcement.
It is also unclear when exactly law enforcement executed the search warrant on Tangeman's residence, or where that residence was at the time. These gaps matter because they bear on how quickly investigators moved once they identified Tangeman's role and whether the evidence-destruction effort succeeded in part.
The broader accountability fights playing out in Washington often overshadow cases like this one. But a $263 million theft ring run by people barely old enough to drink is exactly the kind of case that tests whether the federal justice system can deliver consequences that match the scale of the crime.
Seventy months is a real sentence. Whether it's enough to deter the next crew of twenty-somethings with a laptop and a taste for Lamborghinis is another question entirely.
