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."

Starr was arrested three weeks ago in Salt Lake City on an outstanding warrant related to an earlier drugs charge, and suspicion of felony possession of a controlled substance for allegedly having six Xanax pills and six tablets of the painkiller Opana.

Starr left Alice in Chains shortly after the release of their breakthrough 1992 album 'Dirt,' and before they went on to enjoy greater success during the heyday of Seattle grunge. He later admitted that he left the band because of his drug addiction. His fellow band member, singer Layne Staley, died of a drug overdose in 2002.

After appearing in 'Celebrity Rehab,' where his fellow patients included Heidi Fleiss, Dennis Rodman and Mindy McCready, Starr seemed unable to overcome his addictions. He later appeared on the spin-off show, 'Sober House,' in an acrimonious season during which he assaulted a cameraman and fought with Tom Sizemore.
