Criminals/ Former inmates theory in Dyatlov Pass Incident
Siberia at the time of the tragedy
of Dyatlov Pass Incident was still a land of Gulag. Many political prisoners were released in 1953- 56, but criminals were still behind bars. Many small concentration camps were dispersed all over the region. The closest
such facility to the Dyatlov Pass was Ivlag situated just few miles from a site of a tragedy. Although it is true that there were no escapes around the time of
Dyatlov Pass Incident it doesn't mean that it never happened before. History knows many examples then prisoners would escape and go into hiding for years and even decades at a time. They could have easily missed death of Stalin in 1953 and subsequent amnesty to all political prisoners.
Soviet Concentration Camps were increased significantly at the end of the Great Patriotic War (aka World War II). Thousands of soldiers and officers who wrote or said something against Stalin and the country were arrested upon completion of the military actions. While many men and women were at the front and faced death they often expressed their opinions without fear. You can get killed in a few seconds. Who cares if your political officer recorded your words? And the party did nothing until the end of the war. But once it was over Stalin told his henchmen to get everyone who was unhappy or too honest about Soviet rule. Thousands were send to cut forest in Siberia instead of coming home to their loved ones. It is plausible that these people knew how to kill and were open to the idea.
One of the facts that could tie veterans to this case is the fact two
"obmotki" or puttee were discovered at the cedar and near the tent
as we mentioned earlier. They were widely used among the soldiers in the 40's and later among the prisoners of Stalin's concentration camps. No body knows how it got here and no body knows how it disappeared from the evidence room
or during transportation from Dyatlov Pass. But it did. Given the scenario described above it is plausible to assume that a group of former soldier or officers that were wrongfully accused of crimes against the state (infamous article N58) at the end of the World War II. Using their war experience they might have escaped from prison and they could have lived in Siberia for years. It is also plausible that once they encountered the group of your students, former inmates assumed that getting rid of eye witnesses is better than being reported and chased by the police.
This theory would exaplain the manner and a motif for
killing tourists on the Dyatlov Pass. However it doesn't explain
presence of radiation on clothes. And aside of puttee we have no
evidence of their presence on the Dyatlov Pass or around it.
