Casey Calvert, the 26-year-old guitarist for rock band Hawthorne Heights, was found dead on the band’s tour bus outside Washington D.C. on Saturday. The cause of death is undetermined, pending an autopsy. The band released a statement on their website: ”Today is probably the worst day ever. 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.” Hawthorne Heights’ latest record, If Only You Were Lonely, debuted at #3 on the Billboard albums chart last year. They had just kicked off their Wintour 2007 jaunt on Friday night. It is unknown whether they plan to replace Calvert and finish the tour. (MTV)
