There is more to the story than this. He had some economic problems also. And he was just 1,5 km away from the E4, one of the most trafficated roads in Sweden. On a clear night one can almost hear the lorries from that distance, at least see the hedlights in the sky.

My mother in law got the Altzheimer disease, and she got lost in her own neighbourhood where she had been living for decades. She was just on the other side of her own house, and she could not find it. I suspect this or some other psychiatric illness, but it was a good thing that he was found alive.
