As the kids say: DUH! Where else would it be found?
A lot of newer and more expensive cars have LoJack. The thieves don’t know for sure, so they will abandon the car in some out of the way place to see if the cops will locate it. If not, they might go back and pick it up later. Of course, the cops could keep the vehicle under surveillance and see who comes to pick it up, but in a place like Newark, the next person that tries to take it may have had nothing to do with the original carjacking.
