FBI agent fed Mafia information in Colombo case
A top FBI mob expert allegedly leaked details to Gregory Scarpa Sr., a Colombo family captain, as seven alleged members went on trial for murder conspiracy. The letters cite loanshark data and informant names, with unclear effects on retribution and no charges yet against the agent. Scarpa, an FBI informant until his AIDS death in 1994, faced two assassination attempts during the 1991 War.
