The Real Reason Why John Gotti's Most Loyal Underboss Sammy "The Bull" Gravano Flipped Against him?

He committed nineteen murders for John Gotti. Then he sat in a witness chair and described every single one of them. Sammy Gravano was the underboss of the Gambino crime family and the operational architect of everything that made John Gotti powerful — including the December nineteen eighty-five murder of Paul Castellano that put Gotti in charge. When FBI surveillance recordings from the Ravenite Social Club were disclosed to his attorney in pretrial discovery, Gravano listened to Gotti appearing to position him as the primary operative behind multiple murders — building distance for himself while directing prosecutors toward his underboss. Gravano formally agreed to cooperate in November of nineteen ninety-one. His testimony convicted Gotti on all thirteen counts in April of nineteen ninety-two. In exchange for nineteen admitted murders, Gravano received five years. He was arrested in February of two thousand for running an Ecstasy distribution ring in Phoenix, Arizona. He was released from state prison in September of two thousand and seventeen. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔔 New mob history every week — Subscribe and never miss a case. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📂 WATCH MORE: ▶ John Gotti: The Teflon Don's Three Acquittals and the Trial That Finally Held → [   • The Rise and Brutal Fall of John Gotti - T...  ] ▶ Paul Castellano: The Boss Who Died Outside His Own Dinner Reservation → [   • The Real Reasons Why Paul Castellano Was K...  ] ▶ Joe Valachi: He Killed the Wrong Man.
