The father from Zeya had vanished into the wild near his workplace at Beregovoy village on 29 August, and rescuers later found his abandoned truck, its fuel tank full, and his glasses inside.

He was discovered alive some two weeks later after walking out of the taiga alone on a remote highway after searchers had failed to locate him. The areas is full of both brown and black bears, along with wolves.
