Former mafia member Joseph Salerno. Salerno's damming court testimony was the lynchpin that brought down Philadelphia mafia don Nicodemo "little Nicky" Scarfo. Salerno was drawn into the Cosa Nostra in 1976. After taking part in a mob hit in 1979, Salerno decided to testify against Scarfo. That led to a 200-thousand dollar contract against Salerno and his fleeing into the witness protection program and assuming a new identity. With Stephen J.
