Sawbinder, chime in on this if im wrong, but don't you need the serial numbers and some type of proof of ownership to sell a gun to a gun shop? or a pawn shop? I'm guessing most likely these will be sold to private persons but who knows, I'll be visiting a few around town to see if I recognize something.
The detective said they would look into the store returns things, but it's unlikely they will get anything out of it. The Winchester rifles and a few other guns are possible to recover because of rarity.
Our hopes of recovering anything are little and the insurance company is already haggling on shit, so here comes the legal battle with them.
