Matthews, who had been wearing a seatbelt, showed no sign of trauma after the crash, police said, and alcohol, drugs and speed did not appear to have been factors in the crash. Investigators theorize Matthews might have suffered from some type of medical emergency.

The cause of Matthews’ death was expected to be determined by the coroner’s office.

Anyone with information on the accident was urged to call Inglewood police traffic investigator Jeff LaGreek at (310) 412-5134.
