GS: Is it correct to say that the chest as a construction can have structural fractures? In other words, one blow could cause several fractures?
SN: This indicates that at the contact zone, the impact exceeded the sizes from the first to the sixth rib. It was a large heavy mass. Most likely, snow.
GS: Can you determine when this injury took place?
SN: The presence of blood in the pleural cavity of Zolotaryov unequivocally indicates that he was alive.
GS: In what position was the person at the time of injury?
SN: It can be undoubtedly said that he was lying on his back. And the traumatic effect occurred from front to back, maybe some what from right to left.
GS: The surface on which the person was lying was relatively firm?
SN: Yes. It is unlikely that he was lying in the snow.
They believe it was a snow collapse in this discussion. Possibly a natural made snow bridge,cave. It is likely that he was lying on snow or a compacted snow. Not "in snow" . It's relative .
