Jimmy Hoffa is shown in this 1975 photo. New DNA evidence in the disappearance of the ex-Teamsters boss 27 years ago is insufficient to bring criminal charges, a Michigan prosecutor said Thursday, Aug. 29, 2002. "Unfortunately, this has the markings of a great `whodunit' novel without the final chapter," Oakland County Prosecutor David Gorcyca said. Hoffa, father of current Teamsters President James P. Hoffa, disappeared from the parking lot of the Machus Red Fox restaurant in Oakland County's Bloomfield Township in July 1975. He was 62. (AP Photo/Richard Sheinwald)
