Rock singer Scott Weiland's death earlier in December in a tour bus in a Minneapolis suburb was due to mixed drug toxicity including cocaine, alcohol and ecstasy, and determined to be an accident, the Hennepin County Medical Examiner said on Friday.

Weiland, 48, the former front man for the band Stone Temple Pilots, was touring with his new band, the Wildabouts, when he died in his sleep on Dec. 3, while in Bloomington, Minnesota.

Bloomington police said at the time that they had recovered a small amount of cocaine from the band's tour bus.
