A 22-year-old California man has been sentenced to 70 months in federal prison for laundering millions of dollars tied to a crypto theft ring that prosecutors say stole more than $263 million.

Evan Tangeman, from Newport Beach, was sentenced Friday by U.S. District Judge Colleen Kollar-Kotelly in Washington, D.C., after pleading guilty in December to participating in a RICO conspiracy. The U.S. Attorney’s Office for the District of Columbia said Tangeman admitted he helped launder at least $3.5 million for members of the criminal enterprise.

The sentence also includes three years of supervised release. Prosecutors described Tangeman as a money launderer for a wider group that included database hackers, organizers, callers, target identifiers and residential burglars who targeted hardware crypto wallets.

Tangeman Gets 70 Months After Ninth Guilty Plea

Tangeman’s guilty plea was the ninth secured in the investigation, according to federal prosecutors. The case centers on what authorities called a multi-state social-engineering enterprise that began no later than October 2023 and continued through at least May 2025.

The group allegedly grew out of friendships formed on online gaming platforms, before evolving into a criminal network with members in California, Connecticut, New York, Florida and abroad. According to IRS Criminal Investigation, the enterprise used social engineering to steal hundreds of millions of dollars in cryptocurrency from victims across the United States.

Social engineering attacks do not usually begin with code. They rely on deception, impersonation and pressure, often pushing victims or service providers into giving up access to accounts, devices or recovery information. In crypto, where transactions can move quickly and custody often sits with the user, that kind of manipulation can lead to large losses before victims understand what has happened.

Luxury Cars and Nightclub Tabs Put the Money Trail in Focus

Federal prosecutors said the stolen funds supported an extreme luxury lifestyle. Members and associates allegedly spent crypto proceeds on nightclub services costing up to $500,000 per evening, luxury watches, designer goods, private jet rentals, security guards and exotic cars.

U.S. Attorney Jeanine Ferris Pirro said the enterprise was built on “greed so brazen it borders on the cartoonish,” pointing to spending on Lamborghinis, Rolexes and high-end nightlife.

The DOJ said Tangeman benefited directly from the criminal conduct, including through exotic vehicles and commissions earned for laundering stolen funds. When law enforcement searched his residence, agents identified and seized a black 2022 Rolls Royce Ghost valued at more than $300,000 and a white and black Porsche GT3 RS.

Prosecutors also said co-defendant Malone Lam arranged for the purchase of a widebody Lamborghini Urus for Tangeman, further tying the laundering role to the group’s spending.

Evidence Destruction Shaped the Tangeman Sentence

The government said Tangeman’s conduct did not stop at laundering stolen crypto. Prosecutors accused him of trying to obstruct the investigation after early arrests exposed the scale of the fraud.

According to the DOJ, when co-defendants Malone Lam and Jeandiel Serrano were arrested, Tangeman directed another co-defendant, Tucker Desmond, to destroy digital devices belonging to enterprise members. Pirro said that conduct showed “consciousness of guilt” and was treated accordingly by the court and prosecutors.

That point matters because crypto laundering cases often turn on more than the movement of funds. Prosecutors increasingly focus on the full support network around thefts, including people who convert assets, hide records, destroy devices or help criminals spend the proceeds.

Crypto Crime Cases Are Moving Beyond Blockchain Tracing

The Tangeman case shows how federal crypto investigations are widening beyond blockchain analysis alone. The DOJ described an enterprise that combined online targeting, social engineering, physical burglary and money laundering, making the case closer to organized financial crime than a simple online scam.

The case was investigated by the U.S. Attorney’s Office for the District of Columbia, the FBI’s Washington Field Office and IRS Criminal Investigation’s Washington, D.C. Field Office, with support from FBI offices in Los Angeles and Miami and several U.S. Attorney’s Offices.

For crypto users, the case is another reminder that the weakest point in custody is often not the blockchain itself. It is the person, device, service provider or recovery process that criminals can manipulate. As high-value crypto thefts keep drawing federal attention, money launderers and support actors are now firmly in the enforcement spotlight.
