They probably were beheaded. But before that, in typical Islamic style, their private parts were cut off and stuffed down their throats, and then a dagger was stuck below the chin and rammed up into the mouth, thus securing the jaw. I know that this is gruesome visual, but it has always been done in Israel to captured IDF troops, and it shows you the kind of animals that we are dealing with. That is why the British, in the battle of Khyber Pass in Afghanistan would dig graves for the arabs and throw the bodies in, and then pour pigs blood over it--(the only thing that rattles these bastards.) I am not suggesting that we do this, but it shows that it is not a modern problem.
These guys were worth more alive than dead. Their bodies were found close to where they were abducted. It is highly likely they fought to the death and were subsequently mutilated by their adversaries.
We won't do it...because that's barbaric...(sarcasm)...grrrr.
