Actually, it was Cody Wyrick, a quiet guy who bears an *astounding* resemblance to Arseface, the character who was such a memorable part of Garth Ennis and Steve Dillon's comic book series PREACHER. Another news story reported that Wyrick had once made a suicide attempt by shotgun and miraculously survived. That's exactly what Arseface did, and it's downright eerie to see the similarities of their reconstructed features. Very good research by Steve Dillon.
The news story notes that no finished explosives were found, so there's a good chance Wyrick just had a dime dropped on him by folks who didn't like him. Honestly, I hope that's the case; he's had a rough enough time as it is.
Arseface himself was loosely based on the story of the (now) late James Vance, who survived a suicide pact he'd had with his best friend. Arseface's precipitating incident was the death of Kurt Cobain; Vance claimed that he had been inspired by subliminals in the music of Judas Priest, and unsuccessfully sued the band. The case is the subject of the documentary DREAM DECEIVERS, which is now available online via Google Video. Vance himself appears in it, and once you've seen it you realize Garth Ennis must have.
