DETROIT

--Investigators will take soil samples from the ground beneath a suburban Detroit driveway after a man told police he believes he witnessed the burial of missing Teamsters leader Jimmy Hoffa about 35 years ago, police said Wednesday.

Roseville Police Chief James Berlin said his department received a tip from a man who said he saw a body buried approximately 35 years ago and "thinks it may have been Jimmy he saw interred."

"We are not claiming it's Jimmy Hoffa, the timeline doesn't add up," Berlin said. "We're investigating a body that may be at the location."

Hoffa was last seen on July 30, 1975, outside a suburban Detroit restaurant where he was supposed to meet with a New Jersey Teamsters boss and a Detroit Mafia captain. His body has not been found despite a number of searches over the years.

Innumerable theories about the demise of the union boss have surfaced over time. Among them: He was entombed in concrete at Giants Stadium in New Jersey, ground up and thrown in a Florida swamp or obliterated in a mob-owned fat-rendering plant. The search has continued under a backyard pool north of Detroit in 2003, under the floor of a Detroit home in 2004 and at a horse farm northwest of Detroit in 2006.

Results are not expected until next week.

The FBI had no immediate comment on the new effort in Roseville.
