Police Chief James Berlin said his department had anticipated results Monday from soil samples removed from the site by police and the Michigan Department of Environmental Quality Friday and sent for analysis to the forensic and anthropology department of Michigan State University in Lansing, Mich., but has since learned of a delay. The findings will be available Tuesday, he said.
If the samples, four tubes of dirt each about 4 feet long, come back positive for evidence of human remains, a meeting with the FBI, Michigan State Police and the university will be held to determine who will aid local police in an exhumation, Berlin said.
Hoffa disappeared in 1975, his body never found, and the long list of rumors and theories about his final resting place have included beneath Giants Stadium in New Jersey and beneath the General Motors headquarters in downtown Detroit.
The FBI also dug up a Milford Township, Mich., horse farm and destroyed a barn there in 2006, searching for Hoffa's remains, The Detroit News noted.
The latest search came after an unnamed tipster telephoned Roseville police Aug. 27, saying he had seen what appeared to be a body being buried in a shed with a dirt floor that had been located on the present site of the driveway the day or the day after Hoffa disappeared, the newspaper said.
