Soil tests indicate that no human remains are buried beneath a shed in Roseville, Mich., where authorities were investigating the possibility that the late Teamsters President Jimmy Hoffa might have been buried, officials said.
Michigan State University tested two samples from a home in Roseville, a suburb of Detroit, after an unidentified tipster told authorities that he witnessed a body being buried there the day after Hoffa disappeared in July 1975.
Those tests came up negative for human remains, Roseville police said Tuesday.
The lead appears to be yet another dead end in the search for Hoffa, who ran the International Brotherhood of Teamsters, the country’s biggest labor union, from 1957 to 1971. It joins a long line of false leads that have fueled conspiracy theories for years.
Investigators and other experts had said that they doubted that Hoffa was at the site.
Andy Arena, the former FBI special agent in charge for Detroit, said that while his “gut feeling is that this person saw something,” it defies common sense to believe that the Mafia would have buried the body in broad daylight in a busy suburban area.
“If this guy was standing there watching this, and it was Jimmy Hoffa, he would have been in the hole with him,” Arena said.
