Toxicology reports indicate that there were no drugs or alcohol in singer John Denver's system when his plane crashed into Monterey Bay earlier this month.
The complete autopsy report wasn't complete, but Monterey County Sheriff Norman Hicks said Tuesday that tests showed no alcohol or controlled substances.Denver was killed instantly Oct. 12 when his experimental plane plunged 500 feet into the bay near Pacific Grove. Denver had bought the plane, which was built in Texas in 1987, shortly before the crash.
National Transportation Safety Board investigators recovered and assembled most of the plane and found "no sign of catastrophic failure," safety board spokesman George Petterson said.
A final NTSB report is not expected for months.
