CHICAGO, ILLINOIS – A deputy U.S. marshal has been convicted in Chicago of leaking secret information to the mob about a protected witness in a federal organized crime investigation.
Deputy marshal John T. Ambrose stared straight ahead as jurors returned the verdict Tuesday following almost three days of deliberation.
Prosecutors say it was the first time in the 39-year history of the government’s witness security program that its secrecy was deliberately violated.
Prosecutors say they realized there was a leak when two mobsters were overheard in a prison visiting room talking about having a “mole” inside federal law enforcement.
The 42-year-old Ambrose was acquitted of two charges of lying to federal agents.
