Hello. I was thinking of the cut branches on the tree and the 'window.' I don't think I have ever seen it mentioned this could have been made be external people to view the tent. My thoughts on this being part of the scenario would mean no avalanche and no tree fall (although that is an entirely plausible theory) Someone was tracking them for whatever reason and was watching until they saw they had settled in for the night and then attacked. They walked the hikers down to the fire and tortured and killed them and threw the bodies in the den. Lyuda's positioning reminds me of someone who was dragged by one person by each arm and then left. I don't for a minute put any stock into the footprints precluding any outsiders. I can walk in my backyard on a windy and snowy day and the tracks can all but disappear overnight. While the others were being tortured Igor Rustem and Zina ran for it but were caught and beaten down where they were found. In this version all the injuries to all the hikers occurred while they were alive so I am also assuming the autopsy results were accurate.
This is somewhat in line with what Syunikaev said about the hikers being watched and followed:
https://forum.dyatlovpass.com/index.php?topic=1788.0They were being watched… they were being followed! You see, they arrived, they didn’t even go down our road. There we have security posts all around… And they took a detour along the river and through the camp! They were given a horse there, and they were taken on the horse to the Khanty. They interrogated this Khan, the young Khan kept saying: they were let in through them!
[–] Who – them?
► Dyatlovtsev – they gave it directly to them.
[–] Killers?
► Of course! they were given them into their hands.
[–] So who? Did they kill the Khanty? Or Mansi?
► Khanty… They were watched all the time! how they did, what they did.
[–] Why did you need to follow them?
► Apparently they had a special task! But they went overboard. They saw a lot there! And those places where they shouldn’t have been!
[–] What did they see? What did they see there?
► They saw everything! (thinking) They say that there was no tent there, but they were in another place, where the four were found below, in the stream. They had a labaz there… And how they got there, up there, God knows! That's where they were beaten, all of them in the labaz.
