The former Stone Temple Pilots frontman was found dead on his tour bus prior to a scheduled performance, and a search warrant released by Bloomington, MN police now confirms that a variety of substances surrounded the rocker in his final hours.

According to the Hennepin County search warrant and affidavit obtained by Billboard, Weiland was found “alone in a bedroom” in which an “unknown white substance packaged in baggies” was located “in plain view.” Furthermore, a “baggie with green leafy substance,” Viagra, sleeping pills, a painkiller and Ziprasidone were also found on the bus.
