New to the forums, but I had some burning questions and thoughts after looking at the materials related to this incident.
Without a doubt, based on those materials, I believe these poor souls were tortured, interrogated, and murdered. The injuries the victims received are ones that assailants would inflict with either gun stocks, knives, or stout branches/blunt objects, and there are injuries the victims would receive from kicking and fighting bare-handed. Someone thought these kids had secrets, someone believed they might spill those secrets, and someone thought they all needed to be questioned and removed--the actual secret-holders, and any nearby witnesses. Such a horrible incident, but anything further than this is pure speculation. My personal belief is that a domestic/internal group (perhaps the KGB as others have said) took this opportunity presented by the hike to quietly eliminate a threat to state secrecy.
All that aside, I have a question: Why was the Dyatlov Group removed, but the Blinov Group who were supposedly hiking in parallel left alone? (Again, this is under the murder theory, not an animal or natural disaster theory). Was anyone in that second group ever interviewed or researched, to see if the Dyatlov Group carried a possible threat to secrecy that the Blinov Group did not?
