Hawthorne Heights guitarist Casey Calvert, 25, was pronounced dead at the scene on Saturday after police were called to the band's tour bus outside Washington, D.C.'s 9:30 Club around 2:30 p.m. and found him unconscious. The Washington Post reported that Calvert's death came one day after he and his band mates boarded the bus to begin their Wintour 07 outing, which kicked off Friday night in Detroit. Police are awaiting results of an autopsy.

On the group's Web site, fellow band members announced the death of their "quirky and awesomebest friend on Saturday, who they said had "passed away in his sleep."

"Today is probably the worst day ever," the group wrote. "It's with our deepest regrets that we have to write this. Casey Calvert passed away in his sleep last night. We found out this afternoon before sound-check. We've spent the entire day trying to come to grips with this and figure out as much as possible. At this time we're not sure what exactly happened. Just last night he was joking around with everyone before he went to bed. We can say with absolute certainty that he was not doing anything illegal. Please, out of respect to Casey and his family, don't contribute or succumb to any gossip you may hear. We don't want his memory to be tainted in the least. Casey was our best friend. He was quirky and awesome and there will truly be no others like him! His loss is unexplainable. As soon as we know more we will let you know.

Sincerely, Hawthorne Heights: Eron, JT, Micah and Matt."

that's too bad, I enjoy listening to their music occassionally.

That's definately a bummer... was definately looking forward to seeing them once I got stateside again.

I listened to them yesterday for a while. They will probably find a new guitarist though and still sound the same.

Most likely. Guitarists are a dime a dozen. Trust me, I know...
