NEW YORK -- As notorious mobster John Gotti went to trial for murder and racketeering, federal investigators grilled scores of suspects about secret details surrounding the Gambino boss' precision murder plot against his predecessor, "Big Paul" Castellano.
They were looking for a mole, not a Mafioso.
The nearly 200 people questioned were all in law enforcement, many of them FBI agents stationed from New Jersey to California. The investigation _ sparked by a single phone call from an irate federal judge _ sought the source of a story leaked to a New York tabloid six years after the Manhattan mob rubout.
The FBI fared better with Gotti than its internal probe. While the mob boss went away for life, "no one was identified as being the source of the leaks," a long-buried FBI memorandum concluded 13 months after the February 1992 hunt for the leaker began.
