A suspected drunken driver crashed with a motorcycle and then left the scene, unknowingly driving away with the motorcyclist's dead body lodged in the rear window of his car, investigators said.

Tony Martinez, 54, pulled out of a parking lot Saturday night and cut off motorcyclist Nicholas Justin Campbell, who was traveling about 80 mph, California Highway Patrol spokesman Ron Thatcher said.

The motorcyle crashed into the car and Campbell was thrown through the rear window, Thatcher said. Martinez then drove away and realized when he got home that the motorcyclist was in his car, Thatcher said.

Martinez then drove to a Riverside County fire station where 20-year-old Campbell was declared dead, according to the coroner's office.

Martinez was arrested and booked for investigation of gross vehicular manslaughter, hit-and-run and driving under the influence. Bail was set at $75,000.
