Any cop would know that setting the truck on fire would bring cops swarming like flies on a dead possum.
So there is only one of two reasons for him burning the truck.
Either he wants to draw them to a trap....
Or he has pre arranged transportation to some place far far away and the burning truck is like the magician’s trick...look at this hand while the other hand does its thing.
They’re lucky he didn’t have secondary explosive devices around the vehicle......
Hmmm, tracks in the snow and a burning vehicle. How very discreet! Wonder how many booby traps have been set along that trail.
