Ex-Weezer bassist Mikey Welsh was found dead in his Chicago hotel yesterday after failing to check out of his room on time. Authorities believe narcotics were involved in the death a that fact will be either confirmed or denied today after the autopsy is completed. Welsh had left the band back in 2001 after suffering a nervous breakdown. Staff members at Hotel said Welsh was unresponsive and laying on the floor when they entered the room. He was only 40 years old. [TMZ]
