In the latest effort to solve a mystery that began more than 30 years ago, the Federal Bureau of Investigation said today that it was following a "fairly credible lead" that the remains of James R. Hoffa, the former Teamsters president, could be buried on a horse farm northwest of Detroit.
Using cadaver dogs borrowed from Detroit police, and aided by students and professors from Michigan State University, F.B.I. agents said they were searching an 80-acre horse farm in Milford, Mich.
Daniel D. Roberts, the special agent in charge of the Detroit F.B.I. office, said the search could take weeks.
At a news conference this afternoon on a dirt road at the entrance to the Hidden Dreams Farm in Milford, Mr. Roberts said no trace of Mr. Hoffa had yet been discovered. Nor would he give details of the search warrant, which was sealed by a federal judge in Detroit.
But, Mr. Roberts said, "This is probably a fairly credible lead" in Mr. Hoffa's disappearance. Mr. Roberts, who has been in his position for the past two years, added that it was "the best lead I've seen come across in the Hoffa investigation."
The F.B.I. contacted Mr. Hoffa's daughter, Barbara Hoffa Crancer, a circuit court judge in St. Louis, on Wednesday night, people with direct knowledge of the conversation said today. Mr. Hoffa's son, James P. Hoffa, who is the current Teamsters president, was in Detroit today but had no immediate comment.
Yet, such leads have perennially failed to turn up the body of Mr. Hoffa, who disappeared July 31, 1975, after failing to return from a dinner meeting. Police, who had been contacted by his family, found his 1974 Pontiac the next day in the parking lot of the Machus Red Fox restaurant in Bloomfield Township, Mich.
The latest search is the third in the past two years by the F.B.I., and it follows one of a number of tips that have placed Mr. Hoffa's body everywhere from the Meadowlands in New Jersey to a house in Detroit.
