Criminal Charges Against Agents Reveal Staggering Corruption in the Silk Road Investigation


Two of the law enforcement agents involved in the tangled multi-agency investigation into the Silk Road have been charged by the Department of Justice for stealing hundreds of thousands of dollars (at the very least) in bitcoin. The criminal complaint against former DEA agent Carl Mark Force IV and former Secret Service agent Shaun Bridges alleges money laundering, wire fraud, theft of government property, and more. But more shockingly, it tells the story of a sprawling case tainted by an unbelievable web of corruption. A state’s witness took the fall for an agent’s theft, thus becoming the target for a murder-for-hire—a murder that was then faked by the same agent. The Silk Road case was compromised again and again as Force and Bridges allegedly took every opportunity to embezzle and steal money. With so much bitcoin on their hands, the two had to coax various bitcoin and payments companies to help convert their ill-gotten gains to dollars. When companies resisted, investigations were launched, subpoenas were issued, and civil forfeitures were sought in retaliation.
