S1E12 John Gotti: Convicted

In December 1985, John Gotti emerged as the head of the Gambino crime family in New York after orchestrating the murder of his predecessor, Paul Castellano. However, Gotti's reign faced a significant threat when the FBI managed to persuade his underboss, Salvatore Gravano, to turn state's witness. The trial concluded with a damning verdict: Gotti was found guilty on all charges, including the assassination of Castellano.
