Quiet Riot Singer Died of Coke Overdose

Vegas....80's hair band rock and roller, mysterious sudden death....I guess this finding shouldn't come as much of a shocker except that in the immediate aftermath of his death all of his friends were claiming the dude was basically a tee-totaller....Anyway, cocaine overdoses are rare, this guy must have been on a Al Pacino in 'Scarface' type binge or something...
