During an argument, a man who played Santa stabbed his daughter to death. The argument was over Christmas decorations. This is a little close to "Silent Night, Deadly Night."

Pretty crazy, gave me a smile for a second though. I agree could've been a real silent night deadly night if he went on a rampage as Santa after that.
