Hawthorne Heights Star Overdosed

Hawthorne Heights rocker Casey Calvert died of "accidental substance abuse," according to autopsy reports. The 25-year-old guitarist was found dead on the group's tour bus outside a Washington, D.C. club last month.

In a statement following the tragedy, Calvert's bandmates insisted their friend was "not doing anything illegal."

Autopsy reports suggest the "acute combined effects of opiate, citalopram and clonazepam intoxication" caused his death.
