Can we consider that everyone left the tent on 1079 and made it to the ravine. From the ravine, the two Yuris volunteered to bring firewood. First one, then the other got injured. After a while, other hikers went to check on them and found them but could not help. Clothing was cut for survivors.
This cutting away of clothes argues against murder. First, they would not kill each other without reason.The reason would be associated with the corpses. Second, other assasins would use a method of killing that is not identified in autopsy. Third, taking of clothes is a survival technique, not a degradation of the corpse. Fourth, positioning of the remains suggests respectful placement with the expectation of recovery of the remains.
An assasin's work is to both eliminate a target and send a message. The Yuris do not meet the criteria. If they were found fully clothed, assassinations could be considered.
If one argues that assasins baited the ravine 4 with the two Yuris at the cedar in order to find where they hid, it is logical. If one further speculates that a concussion grenade was used on Zolo, Lyuda and others, it fits. If one believes Igor, Rustem and Zina tried to make a run for the tent and dies, it fits.
The elephant in the room is that no eye witness nor physical evidence exist confirming those circumstantial arguements. Just because something is logically consistent, does not mean the the premises are true. Alternate explanations requiring fewer assumptions are equally logical. These would revolve around weather.
Ms. Smith puts it correctly when she reminds us that we have many theories to work through. We also appreciate that speculation is not a breakthrough. It has been like that for half a hundred years.
