Here is one thing I don’t really understand:
This certainly seemed to start off as a spree killing motivated by perhaps a need for money, a need for transportation or unhappiness at their life situation...we don’t really know yet. Three totally innocent people killed in a relatively short period of time, but since then, as far as we know, they have not hurt anyone else though they are just as short of cash, supplies and transportation as before. Despite the large remote area the two have covered, I do think if they had killed, hurt, robbed, etc anybody else we would have heard about it. Most spree killers just keep on killing until someone, usually the police, put a stop to it. They do not suddenly morph into playing a real-life game of hide and seek.
I just think it’s odd. It makes me think that they are already dead, perhaps by their own hand. If you were going to cause so much chaos and despair, going to show society what super bad dudes you really were, make society sit up and notice you...why do you suddenly stop with the show?
