Charles “Chuckie” O’Brien, a longtime associate of Teamsters boss Jimmy Hoffa who became a leading suspect in the labor leader’s disappearance and later was portrayed in the Martin Scorsese film, “The Irishman,” has died. O’Brien’s stepson, Harvard Law School professor Jack Goldsmith, said in a blog post that O’Brien died Thursday in Boca Raton, Florida, from what appeared to be a heart attack. O’Brien was a constant companion to Hoffa in the decades when the labor leader developed the Teamsters into one of the largest and most powerful unions in the nation in the from the late 1950s to the early 1970s.
