On July 30, 1975, Hoffa was last seen in the parking lot of the Machus Red Fox restaurant in Bloomfield Hills, a suburb of Detroit. The circumstances surrounding his disappearance have never been fully determined. He was said to have had an appointment at the restaurant with Anthony Provenzano, a New Jersey Teamsters official and former Mafia figure, and Anthony Giacalone, a Detroit mobster; both later denied having encountered Hoffa. He was legally declared “presumed dead” in 1982.
Although it is widely accepted that Hoffa was murdered by members of the Mafia, there is no certainty about who was involved. As to the motive, many believe that there was opposition to Hoffa’s efforts to regain the presidency of the Teamsters. A key issue was control of the Teamsters’ pension fund, which had been established by Hoffa and, according to the FBI, was “the most abused, misused pension fund in America.”
