Once again Federal investigators have revived the search for the remains of famed Teamster Leader Jimmy Hoffa. This time the search has moved to a field about twenty miles from where his vehicle was found at a restaurant nearly 38 years ago.

Investigators combed through dirt as excavators tore up the field outside of suburban Detroit as they followed yet another lead as to the whereabouts of Hoffa after nearly four decades. The FBI said that they had enough information to acquire a search warrant for digging up the field.

Special Agent in Charge of the Detroit FBI Division said that the search warrant involved the disappearance of James Hoffa but that the warrant was sealed and details would not be released. Also at the scene was Oakland County Sheriff Michael Bouchard, he said to reporters, “It’s my fondest hope that we can give … closure not just to the Hoffa family, but also to the community and stop tearing that scab off with every new lead and bring some conclusion.”

Searches have been carried out at other farms, vacant lots, in back yards, under swimming pools, at a horse farm, all to no avail. There have been rumors that he was buried in cement in Giants Stadium, ground up for dog food, and buried in a swamp. One thing for certain, the only people that know for sure where Hoffa’s remains are located are the ones who carried out the act.

Alleged mobster Tony Zerilli told a New York NBC news station earlier this year that Hoffa was buried in the Michigan field that authorities are searching today. Zerilli told a CNN affiliate that he had information from another mafia member that Hoffa had been buried in the field as a temporary measure and was to be moved later to another spot near a hunting lodge after the search for his remains had cooled down. The move was never made according to Zerilli. At the time, Zerilli was promoting his book, “Hoffa Found.” Zerilli was in prison at the time that Hoffa disappeared.

The FBI has been looking at Zerilli’s claims for most of this year before acting on his information.

Another version of the Hoffa killing is the alleged deathbed confession of the FBI’s prime suspect, Frank Sheerhan, who was a mafia hitman, teamster official, and Hoffa confidante. He made his confession to his attorney Charles Brandt. In his videotaped deathbed confession, he related that he and two others went to Hoffa’s home and shot him there. Sheerhan said he shot Hoffa twice in the head, and his body was loaded up and taken to a funeral home about two minutes away and cremated there. Sheerhan said the other two men cleaned up the scene where Hoffa was murdered.

Police would find blood evidence at the house, but they could not determine the date of the blood at the scene.

Sheerhan also confessed to having supplied and transported the rifles that killed President Kennedy to David Ferrie. Ferrie figured prominantly in District Attorney Jim Garrison’s investigation of the Kennedy assassination. Less than a week after news of the Garrison investigation went public, Ferrie was found dead in his apartment.

Sheerhan died in a Philadelphia nursing home in December of 2003.

Like John Roselli and Sam Giancana, Hoffa was to testify before the Church Committee. Both Roselli and Giancana were assassinated before they could appear. The Church Commmittee was probing assassinations and other illegal activity by U.S. Intelligence agencies including the CIA.
