When I got home from grocery shopping this morning, Son told me that he called Impound, just because why not. And they had the car. It had actually been found just about the time we were reporting it stolen, abandoned on a limited-access highway.
I am mystified; two people had left remains of eating at McDonalds. They had tried (unsuccessfully) to remove the radio, and had left everything else in the car, even the keys. Didn't take the handicapped tag or the jumper cables. Aside from the way the radio now sits, there's no damage.
We had to pay the $90 towing fee, but otherwise we're okay. I'm not complaining.
