How were those who got away and tried to return to the tent (Zina and Rustem), and then Igor who went after Zina, killed?
According to the autopsy these 3 had no life-threatening injuries and died of the cold. Rustem did have a fractured skull which is probably post-mortem, ..."
Zina had a head injury (except of other defensive and cutaneous wounds) that is described in the autopsy report and also in Maslennikov NB (scan 8): "The closest Kolmogorova 500 meters broken head". Even if this injury was not fatal, it could have made her unconscious and she froze to death.
As for Slobodin, how can anyone say that the skull fractures on both of his temples were post mortem? If there would be only one fracture (along the natural skull joint lines), I would say it is possible that it was caused by freezing brain tissues. Also, the pathologist Vozrozhdenny (who made the autopsies) suggested that Slobodin's skull fractures were probably caused by a blunt object.
If you suggest that some of the injuries were caused post-mortem by transportation, I need to say that you can excuse any of their injuries this way, maybe except of rib fractures. This will lead nowhere - if it would be few disputable injuries then fine, but so many? It is a common practice of some members of this forum to label any evidence that does not fit into their theory as being staged/caused by negligence etc.
Dyatlov - his body position in which he was found was not natural, but of course this fact alone cannot point to murder. Dyatlov is the only person who (according to the autopsy report, and if we omit Doroshenko's head burn) did not have a head injury. However, there is a wound in his hair visible on one of the morgue photos. Also, wounds on both ankles suggest that his leg were tied. Cutaneous wound on his palm was probably from a knife (he grabbed a knife blade in defense).
I would also like to point out that if these 3 people would just froze to death, they would have severely frostbitten feet (and possibly also hands), because natural freezing does not happen immediately, and feet/hands go first.. This was not described in the autopsy reports..
And one more thing. The autopsy report of Krivonishenko states that he froze to death, however, his left foot and leg was severely burned (bursting skin, flap skin from burning, charring). Freezing to death and 3rd degree burns somehow don't go together:)
