Police probing Hoffa claim awaiting soil tests

ROSEVILLE, Mich. (WXYZ\AP) - Authorities investigating a claim that the remains of missing Teamsters boss Jimmy Hoffa could be buried beneath a slab of concrete are awaiting results of soil samples taken from a Roseville backyard.

Police say they expect the results of testing on the soil samples sometime early tomorrow morning. 

Forensic anthropologists were expected to test the samples for human decomposition. The tests would only reveal if something had been buried, not who or what it was.

The samples were removed Friday after officials drilled through the floor of a shed north of Detroit. Berlin said the ground would be excavated if decomposition was found in the samples.

Hoffa was last seen July 30, 1975, outside the Machus Red Fox restaurant in Oakland County, more than 30 miles to the west.

The day he disappeared, Hoffa was supposed to meet with a New Jersey Teamsters boss and a Detroit mafia captain.
