A profile of Sammy “the Bull” Gravano, the admitted mob underboss who testified against John Gotti, the head of the Gambino crime family in New York City, in the early 1990s. Although he admitted to taking part in 19 murders, Gravano was sentenced to five years and, in 1996, entered the Federal Witness Protection program. Given a new identity, he moved to Arizona and soon reverted to his old ways. He was arrested in 2000 for running a large-scale Ecstasy ring.
