A week after his passing, we're still learning more about the final hours of Scott Weiland. The police department in Bloomington, Minn. has released the details of their search of the bus in which the body body of the former Stone Temple Pilots and Velvet Revolver singer was discovered.

According to Billboard, who received a copy of the police report, the Weiland's bedroom on the bus contained an "unknown white substance packaged in baggies" that was "located in the bedroom in plain view." The contents of baggies, it said, was packaged "common with the way narcotics are packaged." A bag of cocaine was discovered in the bunk of bassist Tommy Black, which resulted in his arrest last week. He was released on the afternoon of Dec. 4 "[ending further investigation."

In addition, another "baggie with a green leafy substance" was seized, as were a wide assortment of prescription medication, including sleeping pills, Viagra and Ziprasidone, which Weiland used to treat his bipolar disorder. The Hennepin County medical examiner's office expects the toxicology report to be released within four to eight weeks.

Weiland's body was discovered on his tour bus parked outside the Country Inn and Suites by a friend who received a call from his wife when she was unable to reach him. Upon finding his unresponsive body, the friend dialed 911, and he was pronounced dead at 10:27PM Central.

Mary Weiland, his first wife, wrote an open letter about her ex-husband in Rolling Stone. With a self-described mixture of anger and sadness, she wrote that their children "lost their father years ago" and that what "they truly lost on December 3rd was hope." She described his absentee parenting -- support checks that didn't arrive, the children not being invited to his wedding, etc. -- in the hopes that it would inspire others in similar situations to repair their broken relationships with their own children. She closed by asking that "we don't glorify this tragedy with talk of rock and roll and the demons that, by the way, don't have to come with it."
