Casey Calvert, the 25-year-old guitarist for the emo-punk group Hawthorne Heights, was found unconscious in his tour bus Saturday afternoon before the band was scheduled to play a show in Washington, D.C. He was pronounced dead after authorities were called to the scene around 2:30 p.m.
The cause of death has not been determined. "At this time, we're not exactly sure what happened," the band members wrote in a posting on their Website. "Just last night he was joking around with everyone before he went to bed."
According to MTV.com, police are still awaiting autopsy results, though there is speculation that Calvert's death might have been related to his acute asthma.
