(ROSEVILLE) -- Police in a Detroit suburb plan to take soil samples from under a driveway Friday after a tipster said it could be the final resting place of missing Teamsters leader Jimmy Hoffa. Roseville Police Chief James Berlin says a man claims to have seen a body buried there approximately 35 years ago. Berlin says the man believes it could be Hoffa. He says the Michigan Department of Environmental Quality recently found "an anomaly" while using radar to check the driveway. After the Friday dig, a soil sample will be sent to a forensic anthropologist at Michigan State University to check for human remains. Hoffa disappeared in suburban Detroit in 1975, and his remains haven't been found. The FBI had no immediate comment.
