Results Show No Signs of Jimmy Hoffa - kcentv.com - KCEN HD - Waco, Temple, and Killeen

(KCEN) -- The results are in and a big dig for Jimmy Hoffa's remains was a big bust.

Investigators removed crime scene tape from a backyard near Detroit yesterday.

They dug through the concrete floor of a shed there last week, acting on a tip that they might find the remains of the missing teamsters boss buried underneath.

They took some soil samples and sent them off for testing.

But the results showed no signs of human remains.
