Former bassist of Alice In Chains, Mike Starr, who had been on “Celebrity Rehab” with Dr. Drew back in 2009, was found dead at his home in Salt Lake City, Utah on Tuesday (March 8).

The cops were called to Mike’s home at 1:42 pm. There no information on who made the call and in what condition Mike was found. The cause of death is still unknown.

The 44 year-old bassist was just arrested for felony possession of a controlled substance last month (mug shot here). Mike’s father told TMZ of his son death, “It’s a terrible shock and tragedy.”
