TUCSON, Ariz. -- No charges will be filed against August Busch IV, an heir to the Busch Brewery fortune, who was involved in a fatal accident that killed a female companion last year, the Pima County Sheriff's Office announced Friday.
Sheriff's spokesman Jim Howard said the case was closed because there was insufficient evidence to file manslaughter charges.
He said Busch, then a 19-year-old student at the University of Arizona, was not legally drunk at the time of the accident.
The wrecked car and the body of Michele Frederick, 22, Tucson, were found Nov. 13, 1983 along River Road on Tucson's west side. Busch was found several hours later at home. Authorities said he was disoriented and had suffered injuries, apparently in the accident.
The brewery heir suffered temporary amnesia that prevented him from remembering any of the events shortly before and after the accident.
After the accident, Busch returned to his family's home in St. Louis, Mo.
