Former Alice in Chains bassist and reality TV star Mike Starr, 44, was found dead on Tuesday in Utah.

Mike Starr became a fan favorite during his Celebrity Rehab stint, wherein he openly talked about the substance abuse problems that got him ejected from the band Alice in Chains. The musician often referred to the late Layne Staley as his best friend. He was ejected from Alice in Chains in 1993 due to his drug problems. Staley died of an overdose in 2002. Starr made an appearance on Celebrity Rehab 4 as a survivor of drug problems, inspiring others with his message of hope for the future.

Hope ran out for Mike Starr. So far, the details of his death have not been released. Starr was a longtime addict when he joined the cast of the third season of Celebrity Rehab; Dr. Drew Pinsky said that Starr’s detox was one of the most physically difficult to go through.

Starr made headlines only last month for an arrest taking place in Salt Lake City, where he was allegedly in possession of controlled substances. Dr. Drew, who has already commented via Twitter, called the news of Starr’s death “devastating.”
