The more than three-decades-long search for Jimmy Hoffa’s body isn’t over.
Law enforcement authorities announced Tuesday that soil samples tested negative for human remains after police drilled below a concrete slab at a suburban Detroit residence to test an anomaly detected by radar.
This latest effort in the longtime search for the Teamsters boss who disappeared in 1975 was sparked by a tip.
Police say the tipster did not say Hoffa was buried there, but did say a burial happened around the time he went missing. Police will not release information about the tipster.
"The samples submitted for examination showed no signs of human decomposition," a statement from Roseville Police Chief James Berlin said Tuesday.
Berlin said last week that the homeowners had been "cooperative and excellent to police."
Hoffa's disappearance may have been linked to him trying to regain power in the Teamsters after he was released from prison, according to the FBI.
Hoffa, who was 62 at the time he vanished, was last seen at Machus Red Fox restaurant in Bloomfield Township, Michigan. He was reportedly there to talk with Detroit mob street enforcer Anthony Giacalone and New Jersey Teamsters official Anthony Provenzano. Hoffa may have been under the impression the meeting was to settle a feud between him and Provenzano, but Hoffa was the only one to show up.
Hoffa’s son, James Hoffa, is the current president of the Teamsters.
