Reading about the DPI, I was first surprised with the easy rejection of the Mansi hypothesis: "the Mansi are known to be peaceful people" was given as an argument. This affirmation is not serious, there is no such thing as a "peaceful people" on Earth, and there was never, ever. All people are violent and warlike if they feel the need and have the ability to kill.
Why would the Mansi kill the Dyatlov group ? What could trigger such a violent action ? If the Mansi did it, it was not to steal the Russians's equipment, not to punish them for trespassing on hunting grounds, not for stealing any goods, not even for trespassing on sacred territory. There is one motive which I have never heard of and it is to prevent the Russian for reporting an illegal activity, such a serious one that it would cause a severe punishment from the Soviet authorities. The hypothesis I submit to you is the following : the Mansi attacked the Russians to prevent them from discovering and reporting an illegal activity.
What illegal Mansi activity could happen on that mountain in the winter of 1959 ? There is only one that could justify a covered up by the Soviet authorities : human sacrifice.
Because there is such a deep reluctance to accept this reality, such a shame, despite of hundreds and thousands of human sacrifices still perpetrated in 2022 all around the globe (in Africa, India, Oceania, Asia, Latin America...). See for example : https://www.nrc.no/perspectives/2016/where-dead-childrens-bodies-are-big-business/
Child sacrifice was recently a UNICEF cause. And you can also see Gentle Cannibals
, a documentary from Oxford Humanities dealing about the same issue. Or read the book Gods and Vampires
written by the anthropologist Nathan Wachtel. In India, villagers killed a little girl a few years ago and offered her liver to the goddess in the hope to win the jackpot at the national lottery... In India, a country which sends rockets into space but also where in the remote countryside, villagers sacrifice human beings to the gods. In all countries where it still happens, human sacrifice is legally banned and punished, but people secretly perpetuate the tradition. And in some cases, the ban is respected but the tradition re-emerges due to circumstances, even after decades.
So, if the Mansi performed a human sacrifice at the place called don't go there
(which, in terms of any traditional religious culture, always means we make it there
) and believed that the Russian students were rushing right into the spot, they would have done anything to prevent the discovery of their crime.
They could have attacked the Russians at night, just forced them to leave the tent under the threat of rifles, fired some shots in the air to frighten them and just made sure the tent was ruined: there is no need of more to kill somebody in that cold... just make them run in the night, wait a few minutes... and flee the place on your skis.
What about the Soviet authorities ? They investigate honestly until they find the motive: the cover up of a human sacrifice, and then, they close the file, they cover up the cover up, because it would be unthinkable, an absolute shame, that such a thing ever happened in the very rationalist, very advanced Soviet Union.
The "mystery", the unthinkable, is very often a shame which so great, that our minds refuse to consider the possibility of its reality. Extreme violence, human sacrifice, mass murder, incest, are such realities... these are shameful realities not only for the authors but also for the others, and even much more for the others. And very precisely, the one who is the most ashamed, is neither the author, neither a complete stranger, but a relative: a parent, a fellow citizen... this one is the most interested into hiding this type of crime, into the cover up. As for the death of Michael Clark Rockefeller in 1961, everybody was interested not to find its cause... Even the most serious archeologists prefer to hide the ugly truth, when denial is not possible, as in the following case :
"So far, the team has excavated over 150 skulls. (The researchers chose not display the skulls
because the sacrificed people may have historic ties to people of today's indigenous cultures.)" https://www.livescience.com/26611-ancient-human-sacrifice-site-discovered-in-mexico.html
So, if the Mansi killed the Russian students, it could have been for a motive which was also a motive for the Soviet Authorities to cover up the murder. And such a motive is conceivable... That was just to answer "the Mansi are peaceful people".
That's all, greetings
PS: My personal conviction goes to the avalanche hypothesis, the most probable according to me.
