Searching those two pages yielded one instance of "decapitation":

“I was playing at the park and we came into the clearing and we just saw a body on the floor,” said Maria Delgado, 13. “He was just decapitated — the whole top of his head was gone,”

So I think it's safe to say that a witness report from a 13-year-old who misuses the word "decapitation" doesn't make for a good source.
