No remains found in Hoffa search
OAKLAND TOWNSHIP, Mich. -- Another search for ex-Teamster's boss Jimmy Hoffa came to an end with no body.
The FBI spent the last three days digging up a field in suburban Detroit, inch by inch.
A retired mobster told them Hoffa was buried there under a cement slab.
One investigator called it the most credible tip he had heard in years.
"I'm absolutely confident that respect to the bounds which we conducted our investigation, and in our investigation, there are no remains," said FBI officer Robert Foley.
Hoffa disappeared in 1975.
Over the years investigators have conducted countless searches including a 2006 Michigan dig that cost tax payers $250,000.
