Did it ever occur to anyone that Metal Movers might be soooo willing to help because they knew what they were doing was wrong/illegal? They accepted a stolen vehicle. A simple VIN search would have shown that A: the truck has been reported as stolen or B: The guy selling them the vehicle for scrap was not the actual owner.
Maybe this isn't the case at all, and there's more to this story than what's here. I have never scrapped a vehicle and don't know the "in's and outs" of that process, but there's got to be more than just driving a truck up to the counter and being handed a pile if cash.
