Casey Calvert, the 25-year-old guitarist for emo band Hawthorne Heights, was found unconscious on the band's tour bus several hours before a concert Saturday at Washingon D.C.'s 9:30 Club. He later was pronounced dead at the scene. According to a posting on the band's website, Calvert's bandmates "can say with absolute certainty that he was not doing anything illegal. . . . We don't want his memory to be tainted in the least." Police are awaiting the results of an autopsy.
