Police will drill outside a suburban Detroit residence Friday in the search for Jimmy Hoffa, the labor strongman whose disappearance is one of the most notorious and mysterious in U.S. history.
A tipster told police that a body was buried at the spot in Roseville, Michigan, at around the same time the Teamsters boss disappeared in 1975.
The tipster did not claim it was Hoffa's body, authorities said.
Police Chief James Berlin told CNN Thursday that while the tipster's information seems credible, he's not convinced the body is Hoffa's because of the timeline. He spoke with the tipster on August 22, and believes the person did see a burial.
The tipster did not come forward sooner out of fear, said Berlin.
Dan Moldea, author of "The Hoffa Wars," told CNN the tipster, a former gambler, contacted him on March 30. The tipster used to do business with a man who had ties to Anthony Giacalone, an organized crime figure who was supposed to meet Hoffa the day he disappeared, Moldea said.
"I am very skeptical," Moldea said of the planned dig. If Hoffa's burial had taken place at the spot, it would have been in full view of the neighborhood, the author argued.
And if Hoffa's body was disposed of, it would have been done in a way that no evidence would be left years later, he said.
At 10 a.m. Friday, crews will begin digging, police chief Berlin said. It shouldn't take long to get a sample, which will be taken to a forensic anthropologist at the University of Michigan for analysis.
The reading will determine whether there are human remains at the site, but will not identify them, Berlin said.
"It took us a while to get the proper equipment to do what we're going to do. If this is a person, they've been down there for 35 years. What's a few more days?" Berlin said.
Results from the soil testing should be available next week, the chief told CNN Wednesday.FULL STORY
