Evan Tangeman (Newport Beach) pleaded guilty to laundering about $3.5 million in cryptocurrency as part of a multi-state Social Engineering Enterprise prosecutors say stole roughly $263 million (≈4,100 BTC) in August 2024. Tangeman admitted participating in a RICO conspiracy and faces sentencing on April 24, 2026; he is the ninth defendant to plead guilty. The scheme (Oct 2023–at least May 2025) used stolen databases, impersonation calls and residential burglaries to steal hardware wallets, then laundered proceeds into cash, rental homes, luxury purchases and other expenditures. A second superseding indictment unsealed three additional defendants (Nicholas Dellecave, Mustafa Ibrahim, Danish Zulfiqar); some arrests reported in Miami and Dubai and the investigation remains ongoing.

Summary states ~4,100 BTC (≈$263M) were stolen and Tangeman admitted laundering ~$3.5M as part of a RICO conspiracy; sentencing is scheduled and additional defendants/arrests have been unsealed. The large, concrete theft figure and ongoing legal action make the story market-relevant but not an immediate high-impact trading trigger by itself.
