Search for Jimmy Hoffa Continues in Michigan Driveway

Witness says the labor leader was buried there 35 years ago

A Michigan Department of Environmental Quality crew is scheduled to help police take a soil sample to test for human remains under a Roseville driveway Friday after investigators received a tip that missing Teamsters boss Jimmy Hoffa may be buried there.

The tip originally was received in March by Dan Moldea, a Washington D.C.-based author of the book "The Hoffa Wars." Moldea said he told the man, whom Moldea would not identify but stressed is "not a mob guy," to contact the FBI.
