Quiet Riot's Kevin DuBrow Died of Overdose
Clark County coroner spokeswoman Samantha Charles confirmed the cause after toxicology results were received, the Associated Press reports.
The 52-year-old DuBrow was found dead in his home Nov. 25.
"The cause is cocaine intoxication," Charles said.
Quiet Riot was best known for "Cum on Feel the Noize" in 1983 on the album Metal Health, the first by a metal band to reach No. 1 on the Billboard chart.
DuBrow didn't hide his appreciation for drugs. His most recent album with the band was titled "Rehab."
