I'm leery of it too, but I wish someone here could put on their pajamas and knock this silly story out of the ballpark.
Well for starters I can't find any reference to the alleged death of Raymond Lemme sworn to by Clinton Curtis in The Valdosta Daily Times - www.valdostadailytimes.com - Seems like you would expect a person "found dead with his arm slashed in a hotel room in Valdosta Georgia" to end up in the local newspaper.
Of course it is possible this guy was working on some voting machine software -- the stuff they used in Venezuela, which was reportedly developed by some company in Florida...
