I hope they find prints, unless they find prints not allot of resources are going into your case.
If you have the motivation, go to every business the car, or truck towing the car, would have passed on that road and ask if you can see there video for the date/time 24 hours around when it was found.
It's tedious and time consuming, but sometimes it pays off. Maybe something of value was recorded.
If you get another vehicle, you can do Lo-jack but there are other gadgets out there that can track your car, disable the ignition and more.
Look into it.
