John Gotti was a notorious American mobster who became the boss of the Gambino crime family in New York City during the 1980s. Known for his flamboyant personality and stylish appearance, he earned the nickname "The Teflon Don" because charges against him often failed to stick. Gotti was involved in various criminal activities, including racketeering, extortion, and murder. In 1992, Gotti was finally convicted on multiple charges and sentenced to life in prison without the possibility of parole. His high-profile trials and media coverage brought significant attention to organized crime in America. Gotti died in prison in 2002 from cancer.
