LOS ANGELES (AP) -- Coroner's officials on Tuesday ruled Don Cornelius' death a suicide, nearly a week after the "Soul Train" creator and host killed himself with a gunshot to the head.

The agency made the determination after conducting an autopsy on Cornelius' body Friday. Investigators are still awaiting the results of toxicology tests before issuing a final report.

Police quickly ruled out foul play after responding to Cornelius' Mulholland Drive home early Wednesday morning. His son had alerted authorities after receiving a call from his father.
