Prelude Hoffa's plans to regain the leadership of the union were met with opposition from several members of the
Mafia. One of them was
Anthony Provenzano, who had been a Teamsters local leader in New Jersey and a national vice-president of the union during Hoffa's second term as its president. Provenzano was a
caporegime in the New York City
Genovese crime family. At least two of Provenzano's opponents in the union had been murdered, and others who had spoken out against him had been assaulted. Provenzano, once an ally of Hoffa, became an enemy after they reportedly had a feud when both were in federal prison at
Lewisburg, Pennsylvania, in the 1960s. In 1973 and 1974, Hoffa asked him for his support to regain his former position, but he refused, and reportedly threatened Hoffa by saying he would
pull out his guts or kidnap his grandchildren. Other Mafia figures who became involved in the conflict between Hoffa and Provenzano were
Anthony Giacalone, an alleged kingpin in the
Detroit Mafia, and his younger brother,
Vito. The FBI believes that they were positioning themselves as "mediators" between Hoffa and Provenzano. The brothers had made three visits to Hoffa's home at Lake Orion and one to the
Guardian Building law offices. Their avowed purpose in meeting Hoffa was to set up a "peace meeting" between Provenzano and Hoffa. Hoffa's son, James, said, "Dad was pushing so hard to get back in office, I was increasingly afraid that the mob would do something about it." James was convinced that the "peace meeting" was a pretext to Giacalone's "setting Dad up" for a hit since Hoffa had been increasingly uneasy each time the Giacalone brothers arrived.
Events of July 30 Hoffa disappeared on Wednesday, July 30, 1975, after he had gone to a meeting with Provenzano and Giacalone. The meeting was to take place at 2:00 p.m. at the Machus Red Fox restaurant in
Bloomfield Township, a Detroit suburb; it was the same place where the wedding reception of Hoffa's son James had been held. Hoffa wrote Giacalone's initials and the time and location of the meeting in his office calendar: "TG—2 p.m.—Red Fox." Hoffa left his Lake Orion home at 1:15 p.m. Before heading to the restaurant, he stopped at the
Pontiac office of his close friend Louis Linteau, a former president of Teamsters Local 614 who now ran a limousine service. Linteau and Hoffa had been enemies early in their careers, but eventually became friends. When Hoffa left prison, Linteau had also become Hoffa's unofficial appointment secretary and had arranged a dinner meeting between Hoffa and the Giacalone brothers on July 26 in which they had informed him of the July 30 meeting. Linteau was out to lunch when Hoffa stopped by, so Hoffa talked to some of the staff present and left a message for Linteau before he left for the Machus Red Fox. Between 2:15 and 2:30 p.m., an annoyed Hoffa called his wife from a
payphone on a post in front of Damman Hardware, directly behind the Machus Red Fox, and complained that Giacalone had not shown up and that he had been stood up. His wife told him she had not heard from anyone. He told her he would be home in Lake Orion by 4:00 p.m. to grill steaks for dinner. Several witnesses saw Hoffa standing by his car and pacing the restaurant's parking lot. Two men saw Hoffa, recognized him, and stopped to chat with him briefly and to shake his hand. Hoffa also made a call to Linteau in which he again complained that the men were late. Linteau gave the time of his call from Hoffa as 3:30 p.m., but the FBI suspected that it must have been earlier, based on the timing of other phone calls from Linteau's office from around that time. The FBI estimated that Hoffa left the location without a struggle around 2:45–2:50 p.m. One witness reported seeing Hoffa in the back of a maroon "
Lincoln or
Mercury" car with three other people.
Investigation At 7 a.m. the next day, Hoffa's wife called her son and daughter to say that their father had not come home. At 7:20 a.m., Linteau went to the Machus Red Fox and found Hoffa's unlocked car in the parking lot, but there was no sign of Hoffa, nor any indication of what had happened to him. Linteau called the police, who later arrived at the scene. The
Michigan State Police were also brought in, and the
FBI was alerted. At 6 p.m., Hoffa's son James filed a
missing-person report. The Hoffa family offered a $200,000 reward for any information about his disappearance. The primary piece of physical evidence obtained in the investigation was a maroon 1975
Mercury Marquis Brougham, which belonged to Anthony Giacalone's son Joseph. The car had been borrowed earlier that day by
Charles "Chuckie" O'Brien to deliver fish. Giacalone and Provenzano, who denied having scheduled a meeting with Hoffa, were found not to have been near the restaurant that afternoon. Despite extensive surveillance and bugging, investigators found that the Mafia members were generally unwilling to talk about Hoffa's disappearance, even in private. In October 1975,
Michigan Attorney General Frank J. Kelley went to
Waterford Township to supervise an expedition to locate and exhume Hoffa's remains. The search (which was unsuccessful) was triggered by "a tip from an unnamed
informer who said a group of Mafiosi wanted Hoffa's body found". After years of investigation involving numerous law enforcement agencies, including the FBI, officials have not reached a definitive conclusion as to Hoffa's fate or who was involved. Hoffa's wife, Josephine, died on September 12, 1980, and is interred at
White Chapel Memorial Cemetery in
Troy, Michigan. On December 9, 1982, Hoffa was declared
legally dead as of July 30, 1982, by
Oakland County, Michigan Probate Judge Norman R. Barnard. In 1989, Kenneth Walton, the agent in charge of the FBI's Detroit office, told
The Detroit News: "I'm comfortable I know who did it, but it's never going to be prosecuted because we would have to divulge informants, confidential sources." In 2001, the FBI matched
DNA from Hoffa's hair, taken from a brush, with a strand of hair found in Joseph Giacalone's car, but it is possible that Hoffa had traveled in the car on a different day. As of 2021, digs were still periodically conducted in the Detroit area in search of Hoffa's body, but a common theory among experts is that the body was
cremated. Scott Burnstein, a crime historian and journalist, argued in 2019 that Provenzano's only role in the case was to act as a lure. The Hoffex Memo includes this as a possible motivation for murder. Buccellato listed two waste incinerators and a
crematorium, all in the Detroit area. He doubted the body had been transported a long distance: "It's just not practical." The Hoffex Memo similarly said: "If the Detroit LCN was used to assist in the disappearance, it is unknown why the body would be transported back to New Jersey when Detroit Organized Crime people have proven in the past that they are capable of taking care of such things." Sheeran then claimed Hoffa's body was taken to a crematorium in another state and cremated. Other evidence refutes Sheeran's claims. The truthfulness of the book, including the parts about Sheeran's confessions to killing Hoffa, has been disputed by "The Lies of the Irishman", an article in
Slate by Bill Tonelli, and "Jimmy Hoffa and 'The Irishman': A True Crime Story?" by
Harvard Law School Professor
Jack Goldsmith, which appeared in
The New York Review of Books. Buccellato doubts that the Mafia would have entrusted an Irish American with this role and also believes that Hoffa would have refused to travel that far from the restaurant. In one of his
jailhouse confessions published in a biography released after his death in 2006,
Richard Kuklinski claimed that he was part of a four-man team who kidnapped and murdered Hoffa. Former FBI agent Robert Garrity, who worked on the Hoffa case, dismissed Kuklinski's claims as a hoax. Other authorities have also stated that Kuklinski's involvement in Hoffa's disappearance is unlikely. In 2006 a horse farm owned by Teamsters official
Rolland McMaster at the time of Hoffa's disappearance was searched by the FBI for a period of two weeks, with the total operation cost reaching $250,000. The search was brought on by a tip received from federal detainee Donovan Wells, who had lived with McMaster on the farm. He told the FBI that on the day of Hoffa's disappearance he witnessed seeing a number of cars on the farm, which a short time later were gone. McMaster denied any involvement in Hoffa's murder and stated that he was away on union business in Indiana at the time. In 2012,
Roseville, Michigan, police took samples from the ground under a suburban Detroit driveway after a person reported having witnessed the burial of a body there around the time of Hoffa's 1975 disappearance. Tests by
Michigan State University anthropologists found no evidence of human remains. In January 2013, the reputed gangster
Tony Zerilli implied that Hoffa was originally buried in a shallow grave, with plans to move his remains later to a second location. Zerilli said the plans were abandoned and Hoffa's remains lay in a field in northern
Oakland County, Michigan, not far from the restaurant in which he had been last seen. Zerilli denied any responsibility for or association with Hoffa's disappearance. On June 17, 2013, investigating the Zerilli information, the FBI was led to a property in
Oakland Township, in northern Oakland County, which was owned by Detroit mob boss
Jack Tocco. After three days, the FBI called off the dig. No human remains were found, and the
case remains open.
Thomas Andretta, who died in 2019, and his brother Stephen, who reportedly died of cancer in 2000, were named by the FBI as suspects. Both were New Jersey Teamsters and reputed
Genovese crime family mob associates. The FBI called Thomas Andretta a "trusted associate of
Anthony Provenzano; reported to be involved in the disappearance of Hoffa". In an April 2019 interview with
DJ Vlad, the former
Colombo crime family capo
Michael Franzese stated that he was certain that Hoffa's disappearance had been mob-related. He said he was aware of the location of Hoffa's body and of the identity of his shooter, and had tapes that revealed details of his disappearance. When pressed for information on Hoffa's body, Franzese said, "I can tell you that it's wet, that's for sure", and "Upon good information, again, I think I know who the real shooter was; still alive today, in prison." In a 2018 interview with Value Entertainment, Franzese also makes the "it's wet" claim and adds that "it's deep". He also claims that he has in his possession a recorded tape that "spells everything out" and that he might release this at a later date. In a deathbed statement, a landfill worker claimed to have buried Hoffa's body in a steel drum, 15 feet below the surface in a landfill beneath the
Pulaski Skyway in
Jersey City, New Jersey. In October 2021, the FBI obtained a warrant and completed a site survey of the landfill. In July 2022, the FBI announced that "nothing of evidentiary value was discovered" from the survey. ==Legacy==
