Image Credit: Marty Temme/WireImage.comThe sad passing yesterday of 44-year-old Mike Starr, a founding member of ’90s grunge icons Alice in Chains, has prompted a stream of remembrances from his friends, family, and former bandmates, as well as rock contemporaries like Bret Michaels and Slash.

Though Starr’s cause of death is still unknown, his past struggles with heroin—and his arrest for prescription-pill possesion last month in Salt Lake City—are reflected in many of the statements, including a tweet from former Guns ‘n’ Roses drummer Matt Sorum, who posted “Drugs and Alcohol aren’t a joke. Please take care of yourself and respect yourself. We lost Mike Starr today Rest in Peace man.” Motley Crue bassist Nikki Sixx also tweeted: “RIP Mike Starr. Another fallen soldier to addiction.”

From Avenged Sevenfold’s former drummer Mike Portnoy’s Twitter: “RIP Mike Starr… I watched his struggle on Celebrity Rehab and had my fingers crossed for his recovery. This disease kills… sad stuff.”

Dr. Drew, who treated Starr on Rehab‘s third season and its spin-off Sober House, tweeted “Devastating to hear of Mike Starr succumbing to his illness. So very sad. Our prayers are with his family,”

Starr’s father called his son’s death “a terrible shock and tragedy,” while Starr’s onetime AIC mates Jerry Cantrell and Sean Kinney released a statement that read: “Jerry and Sean are mourning the loss of their friend and ask that the media respect their privacy—and the privacy of Mike’s family—during this difficult time. Their thoughts and prayers are with the Starr family.”

Starr was preceded in death by AIC frontman Layne Staley, who lost his longtime battle with heroin addiction in 2002.
