Stone Temple Pilots singer Scott Weiland died from toxic mix of drugs
US rock singer Scott Weiland died of a toxic mix of drugs including cocaine, tests have shown.
The Hennepin County Medical Examiner's Office in Minnesota released the cause of death, and the pathologist also noted a history of cardiovascular disease, asthma and addiction.
The former Stone Temple Pilots frontman, 48, was found dead on his tour bus in the Minneapolis suburb of Bloomington on December 3.
His three-decade career included solo albums and a spot in the supergroup Velvet Revolver.
Weiland's last band, Scott Weiland & the Wildabouts, had been scheduled to play a show in nearby Medina before his death, but it had been cancelled a week earlier due to poor ticket sales.
Police said they found a small amount of cocaine in Weiland's bedroom and elsewhere on the tour bus.
The mix of drugs in his system also included ethanol and the amphetamine MDA.
Police said they arrested a California man who was travelling with Weiland on tentative drug possession charges. The man has been released.
Weiland rose to fame with Stone Temple Pilots, who became one of the most commercially successful bands to come out of the early 1990s grunge rock movement. The band's 1992 debut album Core sold eight million copies.
The band broke up in 2003, and Weiland went on to front Velvet Revolver alongside rock luminaries Slash, Matt Sorum and Duff McKagan of Guns N' Roses and Dave Kushner of Wasted Youth.
Stone Temple Pilots reunited in 2008 and split again in 2013.
Weiland had a long string of drug and alcohol-related arrests and stints in rehab. In 1995, he was arrested after police found him carrying crack and heroin. He pleaded guilty to felony heroin possession in 1998. His arrests for drug possession and stints in rehab led the Stone Temple Pilots to cancel tour dates and contributed to their 2003 break-up.
