I agree with Charles; a person in Lyuda's condition, with broken ribs, could not climb into this strange position, arms up, on her knees with feet dragging, while in the throes of dying. In other places, it is said that she was lying flat on the ground when her ribs were compressed hard enough to fracture them, and that she died about 10 minutes later, as one of the broken ribs pierced her heart. And with a pierced and gushing heart, she got to her knees, put her arms up, and leaned over a ridge? I also notice in the autopsy report that she had "extraordinary mobility" of the thyroid, which can indicate a strangulation or near-strangulation; "extraordinary" definitely indicates something was pressing on her thyroid (neck) area.
As I said in the earlier message, Dyatlov's arms also indicate someone grabbed him by the elbows and pulled him. The two at the cedar tree also show this "moved after death," but this could be their friends, who took their clothes and kindly repositioned them.
I think Lyuda's body shows the most clues of what happened.
