Thanks for the vid - the guy is a mess. It looks like he might have been an Arab suicide bomber or similar who had the explosives strapped around his chest or waist. In these circumstances the head and legs are usually blown off with almost no damage and the torso is virtually obliterated.
I dare say that several forum members would have smuggled one or both of those legs out of the morgue given half a chance !
No - I would defiantly disagree that this is the result of an explosion. Using my clinical expertise I would say that this person was cut up after death. The wounds are too clean, no dirt, no char. Yep, there was care taken here.
