He secured the first national agreement for teamsters' rates in 1964 with the National Master Freight
Jimmy Hoffa caused by the 1975 disappearance of her husband, because her health had declined steadily since then. She is entombed in Michigan. In 1989, Kenneth Walton, the head of the FBI's Detroit office, told "The Detroit News" that he knew what happened to Hoffa. "I'm comfortable I know who did it, but it's never going to be prosecuted because ... we would have to divulge informants, confidential sources." In 2001, the FBI matched DNA from Hoffa's hair—taken from a brush—with a strand of hair found in a 1975 Mercury Marquis Brougham driven by longtime friend Charles "Chuckie" O'Brien on July 30,
