Okay. So, in my opinion, it seems pretty apparent that the fall itself didn't kill him. I'm basing this on the complete lack of any apparent damage reported to his body - nothing broken, not so much as a laceration or bruise. And, if that is the chute in my previous screen shot, it's not terribly steep, and as previously mentioned by someone else, it would be smooth so as to allow garbage bags to go down without breaking open.
So, what are we thinking for cause of death? I suppose if he was already passed out when he went down the chute, and landed face-first, asphyxiation could be likely (as previously mentioned by bakerlady). Or, by that same token, alchohol poisoning? If he choked on his own vomit, wouldn't that be determinable by the physical autopsy?
Also, if he was passed out when he went down the chute, that begs the question, how did he get in there? Two theories have already been raised; a joke gone wrong, or angry security guards.
(Sorry if this is graphic, just trying to understand what could have happened here.)
