There were two headless bodies. The photo that appeared here was of the body of an Iranian professor who had been kidnapped and beheaded a few days before the Berg video came out. I don't know if his head was found or if any group ever claimed "credit" for the deed.
Berg was found tied and dangling from an overpass, with his head placed at his feet, IIRC. He was identified through DNA, in addition to visual identification.
That's like the other guys...4 I think...that were dragged through the streets...set on fire, I think...and also tied and dangled from an overpass. Weren't those guys some kind of contractors? (maybe another Michael Moore film crew...<8^\....)
