Slipknot bassist Paul Gray 'died of overdose'
Test results have shown the bassist for heavy metal band Slipknot died of an accidental overdose of morphine and fentanyl, a synthetic morphine substitute, police said.
Paul Gray was found dead at a hotel room in Des Moines, Iowa, on May 25. A hotel worker told emergency crews that a hypodermic needle was found near Gray's body and that pills were found in the room.
The autopsy showed he died of an overdose, police said. They also said tests revealed signs of significant heart disease.
No evidence has been found showing Gray had a prescription for the drugs, police spokesman Sgt Dave Disney said. Police are trying to find out how Gray got them.
"There is no evidence that a doctor prescribed either one of those substances," Sgt Disney said.
He added that charges are possible but that it is too early to discuss specifically what those charges could be.
Gray was a co-founder of the Des Moines-based band known for their grotesque masks, thrashing sounds and aggressive, dark lyrics.
Slipknot emerged in the mid-1990s and their 1999 debut album sold about two million copies. The band won a Grammy in 2006 for best metal performance for the song Before I Forget.
