Frank Sheeran was an American labor union official and alleged mobster, born on October 25, 1920, in Darby, Pennsylvania. He is best known for his connections to organized crime and his role as a hitman for the Buffalo crime family. Sheeran's life and activities were later popularized in the book "I Heard You Paint Houses" by Charles Brandt and the film "The Irishman," directed by Martin Scorsese. Sheeran served in the U.S. Army during World War II and later became a union leader in the Teamsters. His relationships with prominent figures, including Jimmy Hoffa, the former president of the Teamsters, played a significant role in his life. Sheeran claimed to have been involved in Hoffa's disappearance in 1975, which remains a mystery to this day.
