Just bumping this thread with an article regarding the event written in the Sun yesterday. It provides more information, although not much, please find it
here.
I have also been contacted via PM from a poster who would rather remain anonymous saying that both his cell phone and wallet were found on him ruling out robbery and suggesting a random beating. There also seems to be a strange gap between when he was last seen (10:45pm) and found (12:45am) even though both locations are only a block away.
