I Heard You Paint Houses

In his book, I Heard You Paint Houses: Frank "The Irishman" Sheeran and the Closing of the Case on Jimmy Hoffa (2004), author Charles Brandt claims that Frank Sheeran, an alleged professional killer for the mob and longtime friend of Hoffa's, confessed to assassinating him. According to Brandt, O'Brien drove Sheeran, Hoffa, and fellow mobster Sal Briguglio to a house in Detroit. He claimed that while O'Brien and Briguglio drove off, Sheeran and Hoffa went into the house, where Sheeran claims that he shot Hoffa twice behind the right ear, and that he was told Hoffa was cremated after the murder. Further, Sheeran also admitted later to reporters that he murdered Hoffa, yet, blood stains found in the Detroit house where Sheeran claimed the murder happened were determined not to match Hoffa's DNA.
