Who murdered the participants in the Dyatlov expedition?

Audiobook Who Murdered the Participants of the Dyatlov Expedition? by Martin Lavay, read by Artificial Intelligence. THE TRAGIC END OF DJATL'S EXPEDITION They were found in winter, dressed only in their underwear, scattered in the snow far from the camp. Burned, mutilated. With crushed chests, no eyes, no tongues... Their clothes were radioactive, their camera had a picture of a figure resembling a snowman. How did nine university students who wanted to spend the night under the Ural Dead Mountain die? Did an avalanche kill them? Strong electrical discharge? Ball lightning? Plasmoid? A newly developed weapon? Soldiers? Drunken Russian paparazzi? Native Manx? Chants? Gulag convicts? UFO? Snowman? Did they kill each other?
