The FBI said Tuesday that it found no trace of Jimmy Hoffa after digging up a suburban Detroit horse farm for two weeks in one of the most intensive searches in decades for the former Teamsters boss.
The search involved dozens of FBI agents, along with anthropologists, archaeologists, cadaver-sniffing dogs and a demolition crew that took apart a barn.
However, Judy Chilen, assistant special agent in charge of the Detroit FBI, said the investigation into Hoffa's 1975 disappearance is ongoing.
"There are still prosecutable defendants who are living, and they know who they are," she said at an afternoon news conference.
The FBI began excavating the intriguingly named Hidden Dreams Farm 30 miles northwest of Detroit on May 17, acting on a tip from Donovan Wells, an ailing federal inmate who once lived on the farm and was acquainted with its former owner, 92-year-old Hoffa associate Rolland McMaster, according to a government investigator.
The FBI said Tuesday that the search was expected to cost less than $250,000.
