Imagine the searchers never find the tent or any of the bodies.
I think it was nearly the case... the bodies were all covered by snow, the exception is Igor's arm and the two Yuris being under only powder snow. If it snowed a bit more, or the wind was subsequently less strong, the tent would have been completely covered too...
This means no diaries, no Evening Otorten, no cut tent, no photos of lights in the sky (specks of dust on a negative?), well, no photos from the trip at all.Parts of their tracks might be found, along with their former campsites. The labaz is unlikely to be found..
If you were the investigator, what would you conclude in that case?
(Or, to go one step further, if you were a conspirator staging the incident, which outcome would you prefer? What actually happened or the scene never being found?)
