4 tires of cadillac escalade esv 2010 were moved by someone last night。
After policemen came to take report, they fund the bad guy also smashed the top of the window and removed a lot of parts from inside.
This never happened in where I am living.There are at least another 7 escalades(有长有短） outside ,but the bad guys only took the parts from my car...
but what will they use the parts for if they don't drive the car?
