Hoffa disappeared at, or sometime after, 2:45 pm on July 30, 1975, from the parking lot of the Machus Red Fox Restaurant in Bloomfield Township, an affluent suburb of Detroit. According to what he had told others, he believed he was to meet there with two Mafia leaders—Anthony Giacalone and Anthony Provenzano. Provenzano was also a union leader with the Teamsters in New Jersey, and had earlier been quite close to Hoffa. Provenzano was a national vice-president with IBT from 1961, Hoffa's second term as Teamsters' president.
When Hoffa did not return home that evening, his wife reported him missing. Police found Hoffa's car at the restaurant but no sign of Hoffa himself or any indication of what happened to him. Extensive investigations into the disappearance began immediately, and continued over the next several years by several law enforcement groups, including the FBI. However, the investigations did not conclusively determine Hoffa's fate. For their part, Giacalone and Provenzano were found not to have been near the restaurant that afternoon, and each denied they had scheduled a meeting with Hoffa.
Hoffa was declared legally dead in 1982, on the seventh anniversary of his disappearance, when he would have been aged 69.[
