Gadol, your question requires possibly that the abductor be more likely to be Jewish or not.
So, if this is happening on Rt 9, simply count whether it is closer to Lakewood or Tom’s River …
or maybe what is the car direction (from which town it is going).
On the other hand, in laws of iyush for the lost item, it is possible that there is “rov goyim” even for an item left in a shul – as Jews are there to daven, so a non-Jew is more likely to find it. So, the same thing here.
But the real question is that we do we do if H’V abductor is Jewish? As the punishment is misa, do we keep him until moschiach comes, or do we transfer him to Texas for the punishment?
