OAKLAND TOWNSHIP, Mich. — Federal agents revived the hunt for the remains of Jimmy Hoffa on Monday, digging around in a suburban Detroit field where a reputed Mafia captain says the Teamsters boss' body was buried.
Authorities used excavation equipment to root around in the Oakland Township property, about 25 miles north of Detroit. The FBI halted the search for the day at about 7 p.m., and planned to resume their efforts on Tuesday.
Robert Foley, the special agent in charge of the FBI's Detroit division, made a few brief comments during a news conference about the latest search for union leader who went missing in 1975. He said the warrant to search the property was sealed, and that authorities wouldn't be disclosing the details of what they were seeking.
Foley didn't mention the name of Tony Zerilli, the reputed Mafia captain who told Detroit TV station WDIV in February that he knew where Hoffa was buried. Zerilli, who promoting a book, "Hoffa Found," said the FBI had enough information for a search warrant to dig at the site, and that he had answered every question from agents and prosecutors.
Oakland County Sheriff Mike Bouchard, who joined Foley at a news conference, said it was his "fondest hope" to bring closure for Hoffa's family and the community.
Hoffa, Teamsters president from 1957-71, was an acquaintance of mobsters and an adversary of federal officials. The day in 1975 when he disappeared from a Detroit-area restaurant, he was supposed to be meeting with a New Jersey Teamsters boss and a Detroit Mafia captain.
Since then, multiple leads to his remains have turned out to be red herrings.
In September, police took soil from a suburban backyard after a tip Hoffa had been buried there. It was just one of many fruitless searches. Previous tips led police to a horse farm northwest of Detroit in 2006, a Detroit home in 2004 and a backyard pool two hours north of the city in 2003.
Zerilli's lawyer, David Chasnick, said his client was "thrilled" that investigators were acting on the information.
"Hoffa's body is somewhere in that field, no doubt about it," Chasnick said. He said his client wasn't making any public comments.
Chesnick said Zerilli told him there used to be a barn in the field, and that Hoffa's body was buried beneath a concrete slab inside the barn.
Zerilli was convicted of organized crime and was in prison when Hoffa disappeared. But he told New York TV station WNBC in January that he was informed about Hoffa's whereabouts after his release.
Andrew Arena, who was head of the FBI in Detroit until he retired in 2012, said Zerilli "would have been in a position to have been told" where Hoffa was buried.
"I still don't know if this was a guess on his part. I don't know if he was actually brought here by the Detroit (mob) family," Arena said. "It's his position as the reputed underboss. That's the significance."
Keith Corbett, a former federal prosecutor in Detroit who was active in Mafia prosecutions touching on the Hoffa case, said it was appropriate for the FBI to act on Zerilli's assertions.
"You have a witness who is in a position to know, who says he has specific information," Corbett said. "The bureau has left no stone unturned."
Corbett also defended authorities for repeatedly spending time on what turned out to be dead ends.
"Anytime you look for somebody and don't find the body it is embarrassing," Corbett said. "The thing the public isn't aware of, but police know, is there are a lot of dead ends in an investigation"
