Scott Weiland, lead singer of Stone Temple Pilots and Velvet Revolver, was found dead Thursday at a tour stop in Bloomington, Minn., with his band The Wildabouts, according to posts on his social media accounts. He was 48 and reportedly died in his sleep.

According to Billboard, Bloomington police responded to a call about an unresponsive male in a vehicle that was parked in a motel parking lot Thursday night, and pronounced Weiland dead at the scene. His death is under investigation.

Born in San Jose, Calif., Weiland founded Stone Temple Pilots with Robert and Dean DeLeo in the mid-1980s. The band found mainstream success in the 1990s with hit singles including "Sex Type Thing," "Creep," and "Interstate Love Song." The band officially broke up in 2002, but carried on with other incarnations while Weiland went on to form the supergroup Velvet Revolver with members of Guns N' Roses.

Weiland's struggles with addiction and substance abuse, including heroin use, were well documented. In 1995, he was sentenced to probation for buying crack cocaine, and also had DUI arrests in 2003 and 2007. He checked into rehab in 2008 but never completed the program, according to Billboard. He had also been diagnosed with bipolar disorder. In 2011, he released an autobiography, Not Dead & Not for Sale.
