 Salvatore "Sammy the Bull" Gravano | Notorious Mafia hit man-turned-canary Salvatore “Sammy the Bull” Gravano has been released from an Arizona prison five years early. The infamous 72-year-old mob rat, who brought down John 'the Teflon Don' Gotti in exchange for a 1991 plea deal in which he confessed to involvement in 19 murders, was let out September 18th. He’ll remain on federal parole for the rest of his life. He has spent the last 17½ years in prison. Originally a mobster for the Colombo crime family, and later for the Brooklyn faction of the Gambinos, Gravano was part of the group that murdered Gambino boss Paul Castellano. Gravano played a key role in planning and executing Castellano's murder, along with John Gotti, Angelo Ruggiero, Frank DeCicco, and Joseph Armone. After Castellano's death, Gotti elevated Gravano to underboss, a position he held at the time he became a rat. |  |
