The placement of the car is what would make me think this is possible. I have said before, I could think of several better places they could have left it. It has always seemed like they dumped it there as it was the first "out of the way" place they came to.
A person who does not know this area would not think to go further up to even more secluded areas.
does that road dead end.....could the perps be trying dump the car on the way out of town?
