Connecticut2026-08-09 05:42:56Three St. Louis Men Charged in Robbery Plot Tied to Bitcoin TheftFederal prosecutors in Connecticut have charged Sedric Louis, John Davis and Martel Williams, three St. Louis men, with conspiracy to interfere with commerce by robbery. The men are accused of plotting to break into a residence and force victims to transfer cryptocurrency linked to a bitcoin theft worth hundreds of millions of dollars. Each faces up to 20 years in prison. According to prosecutors, the trio traveled to Connecticut between Aug. 21 and Aug. 24, 2024, rented a car, prepared air guns and walkie-talkies, and spent two days watching a target and his parents. They abandoned the plan over concerns that residential security cameras would capture their movements. A different group from Florida then carried out the same scheme; six people were arrested Aug. 25 in connection with a Lamborghini Urus carjacking. Louis and Davis have been held since June 25 and pleaded not guilty July 30 in Bridgeport federal court. Williams entered the same plea July 17 and was released on bail. Prosecutors said the planned targets were parents of people involved in the bitcoin theft. The indictment is not evidence of guilt.1730
bitcoin theft2026-08-09 05:40:16Three Men Face Up to 20 Years for Plot to Kidnap Bitcoin Heist Victims' ParentsFederal prosecutors in Connecticut have charged Sedric Louis, John Davis and Martel Williams with conspiracy to interfere with commerce by robbery, alleging they plotted to break into a home and force the transfer of cryptocurrency linked to a bitcoin theft valued at hundreds of millions of dollars. Each faces up to 20 years in prison. The three men from St. Louis traveled to Connecticut in August 2024, rented a vehicle and obtained air guns and walkie-talkies. They watched the target and his parents for two days, then abandoned the plan out of fear that home security cameras would identify them. A separate group from Florida later executed the same scheme and six people were arrested on Aug. 25 in connection with a carjacking involving a Lamborghini Urus. Louis and Davis have been held since June 25 and pleaded not guilty on July 30. Williams pleaded not guilty on July 17 and was granted bail. Prosecutors said the intended victims were parents of a person linked to the bitcoin theft. The indictment is not proof of guilt.1820
COLDCARD2026-08-05 21:37:04Galaxy Research: 1,159 BTC in Largest COLDCARD Theft Stay Frozen as Smaller Attacker Starts MixingAccording to Bitcoin News, Galaxy Research has disclosed details on the largest known COLDCARD theft, involving 1,159 BTC. Those funds are spread across seven attacker addresses and have not yet been touched — no Bitcoin has been cashed out or sent through a mixing service. The coins were stolen in a window of 41 minutes, yet roughly 600 attacker addresses have already been flagged by law enforcement agencies, exchanges and blockchain analytics companies. In a separate development, a smaller-scale attacker appears to have started washing funds. On-chain analysts tracked 64 BTC moving into a mixer; initially only about 10 BTC completed the mixing process, while 54 BTC returned as change and were split into outputs of roughly 7 BTC each for further mixing. Analysts note these unusually large outputs are still easy to follow, so the laundering effort remains relatively transparent.1810
