Police in Siberia are now trying to piece together a mystery that unfolded after four friends went on a fishing expedition in August in the endless taiga.
Three months later, only two men came back from their adventure along the remote Sutam River, after they were located in the Sakha Republic (Yakutia) by a rescue helicopter from the Russian Emergencies Ministry, which saved their lives.
Alexander Abdullaev, 37, and Alexei Gradulenko, 35, were found alive - but only just. They were extremely weak, having survived temperatures of below minus 22F in the coldest inhabited region on the planet.
One body was found and one is still missing. The police are not certain if the corpse is that of Viktor Komarov, 47, or Andrei Kurochkin, 44.
But they do think that the dead man was murdered.
