I stumbled across this on the local news. http://www.kctv5.com/story/32368598...t-found-dead-while-hanging-near-walhalla-home From what I can gather in the very limited news report, this guy was working by himself and died from suspension injury after being knocked out. Others might find a better report or know more about this. Really guys. Quit working by yourself. If nothing else bring your wife/girl friend/children along just to call the rescue team.
