Mike Starr, the original bassist for Alice in Chains, has died at the age of 44. Police say his body was found at a house in Salt Lake City, Utah Tuesday afternoon.

The cause of death has not yet been announced, but a spokesman for the Salt Lake City Police Dept. said, "There is nothing to indicate that this was foul play by another individual."

Starr's father told TMZ "It's a terrible shock and tragedy."

Starr battled drug addiction for many years, and went public with his substance abuse problems in 2010 when he appeared on Season 3 of VH1's 'Celebrity Rehab With Dr. Drew.'

Dr. Drew Pinsky expressed his condolences via Twitter: "Devastating to hear of Mike Starr succumbing to his illness. So very sad. Our prayers are with his family."
