The search may be nearing an end to find the body of Jimmy Hoffa.

Authorities in Michigan drilled under a Detroit home and took two soil samples after receiving a tip that a body was buried under a concrete slab around the time that Hoffa vanished.

Police Chief James Berlin said that the investigation has been started after a "credible" tip was received. The information led to a home in Roseville, Michigan.

Detection using radar has found that there's a strange anomaly underneath the concrete slab. The authorities have stated that the samples show no "discernible remains" such as body parts. Tests on the samples will be able to identify if they are human remains, but they won't be able to identify to who they belong. If they are human it will bring up a deeper investigation and excavation of the area.

"If they are positive, we will then start excavating," Chief Berlin reported to CNN as well as saying that the soil tests should be done by next week.

The suburban home that is the alleged site of the body is currently occupied by homeowners. Chief Berlin said that they've been "cooperative and excellent to police."

The former head of the Teamsters was last seen in 1975 before disappearing without a trace of his body - making himself one of the most famous missing people in America at the age of 62.

Hoffa had made a name for himself as a powerful union leader. He was sent to prison in 1967 and subsequently pardoned by then President Nixon four years later on the term that he didn't try and return to the union until at least 1980. Hewas last seen in Bloomfield Township, Michigan, at the Machus Red Fox restaurant where he supposedly met with a Detroit mobster and a Teamster official.

The FBI has long thought the disappearance could have had something to do with Hoffa trying to return to power as head of the Teamsters.

Hoffa's son, James P. Hoffa, followed in his father's footsteps as he's currently the president of the Teamsters.
