For Russian-speaking people, one interesting investigation of Dyatlov incident is ongoing here: https://www.youtube.com/channel/UCDZTS1BXsSHUkZeVK5T1q7w/fea... - The author is an artist who is looking for anatomical anomalies in the photos from morgue (i.e. wrong length of the bone -> possible fracture, etc). He also tries to find the correspondence between the found abnormalities and omissions made in the autopsy reports (i.e. for one of the victims whose photo indicates that they might be missing an eye, the autopsy report conveniently describes only the other eye...)
