A product of Darby, Delaware County, Frank Sheeran was a former president of Wilmington’s Teamsters Local 326 and purported mafia hit man whose main claim to fame was killing Jimmy Hoffa in a mob assassination in 1975. But as Slate wrote earlier this year, Sheeran could also be referred to as the “Forrest Gump of organized crime” because he also claimed to have been clandestinely involved with major events like the Bay of Pigs invasion and the assassination of President John F. Kennedy, as well as the murders of other mafiosi, like Crazy Joe Gallo, and bribes to people including President Richard Nixon — some of whom actually make it into The Irishman. Ultimately, Sheeran, who is played by De Niro in the movie, died in a Philadelphia-area nursing home at age 83 in 2003.
