Murder of Richard Castucci: Proved.
Flemmi said he learned from former FBI agent John Connolly that Castucci, a 47-year-old Revere nightclub owner, had tipped off the FBI to the existence of a Winter Hill Gang safe house in New York City. Castucci was lured to a Somerville apartment by Flemmi and Bulger and murdered by John Martorano on Dec. 30, 1976. Flemmi said in testimony it was a collective decision to kill Castucci.
