(shame, shame, everybody knows my name.)
I too have a BA in Anthropology. My forte was osteology. Never really enjoyed the fleshy bits, just the pearly whites . . .
I worked in law enforcement before going on to masters work in another related field; participated in about a dozen murder investigations at one level or another.
The absence of blood is one of those things that indicates a body has been moved from the perpetration scene. I don't really want to go back and look at the photos, but a lot of the blue/black marks seemed like haematomas (bruises). Dead bodies bruise where they are propped up against something, or bound with something (even a bra or sock hem). Or have something lie on top of them (a book, a bottle, a sack of groceries).
Most people imagine there must be buckets of blood at a crime scene (TV), but that really isn't the case.
The last murder I worked was of a woman killed in her home. There were two small puddles of blood, but not enough. THere was spatter, so we were certain that the murder had been done there; but why so little blood? later, it was determined that the perp had stabbed her while she was wearing a poly-filled parka. The parka soaked up almost all of the blood. Days later, he had removed the parka (it was his) and tried to dispose of it. It was found in a partly burnt oil drum. It was enough to get him life. But it goes to show that absence of blood doesn't mean much during the winter, or where there is malice and disturbance to the scene.
The fact that this dude is nude nullifies the lack of blood, IMO. Genital/anal mutilation is concomminat with homosexual assault, almost always by an assailant who new the vic (the shepherd case in montana . . .)
Honestly folks, I am by no means an expert; but wounds are like snow-flakes--no two are alike. Insects, carrion-feeders, temperature, time, all of those factors can distort a wound to the point you can't tell ANYTHING without chemical or bone tests. With this one, if the wounds are dubious, the flesh ought to be removed and the bones checked for blunt/blade/bullet marks. Bet you'd find plenty.
Was the autopsy done in the field? That's not an autopsy, that is called 'curious cops.' Why aren't there lab photos?????? Chemical and trauma analysis would answer your questions, id lay 50 on it.






But seriously I see satanic cult in this rather than aliens.
