"Stories of people "dropping out" are very common up here. In fact, the "end of the roaders" gravitate to Alaska. Unfortunately, the criminally insane are in that group. Alaska is a magnet for "individuals".
Tell you a story, true one. I came up here in 87 when there was a job opening in Fairbanks, moved from the NW. Worked for a computer company. The guy who quit in Fairbanks told the company he would work for them in Fbx. 5 years, no more. He quit, dropped out, went up into the Yukon Charley country in the wilderness, with a dog team, and got dropped off by a plane. A certain time later the plane was supposed to reprovision him in the winter, but never showed up. He had a rough time, eating squirrels, rabbits, whatever. One day he was splitting firewood and his axe got him in the leg opening a big gash. He stitched himself back together with sewing stuff. During breakup, he came strolling into our office, with clothes so ragged not all his body parts were covered. He had a bear skull under one arm. Had his fill of the wilderness experience, and was going back to college back east to finish his degree. He did so, and hired on with IBM.
A common Alaska story. Sort of the same type of story as the McCandless guy. Back to the end of the roaders, every village has stories of a crazy white guy that went berserk, sometimes killing someone or several people. Manley, Ruby, McCarthy, I only know the ones in my neck of the woods. Extreme yes, but it happens."
