Living here in Hachinohe, I can tell you that it is very possible to drive all through the city at a late hour with a dead body in the back of your car and not a person would notice. They roll up the sidewalks pretty early here. I think I know the route this guy took to get from Misawa to Hachinohe. Probably AO knows it as well. It goes past the industrial section of the city and skirts the main part of Hachinohe. It also borders the ocean, and there are no houses out there.
But my question still is why go that way, I know a lot of you have never been here, but just north of where Misawa is, there is a huge track of bush and mountain roads.
But we have concluded that the guy is an idiot so there is no sense trying to figure out what he was thinking. But I mean a train track? Was he hoping the train would smash into the car destroying th evidence?
