It's still going to be considered a civil and not criminal matter. If he turned over firearms to the dealer to sell on his own accord, he gave the dealer legal possession of his property.
The fact that the dealer was supposed to sell them and give him money in return was a contract (read, civil) issue. The owner out the money can get in line to sue the business owner, but a criminal case won't be made. It's the same as the dealer buying firearms from a distributor, selling them, but still having outstanding bills with the distributor. Not a crime. Just wrong and bad business.
Actually, you're wrong. This is not a civil case.
Let's talk about this in the context of cars, not guns. You can make an agreement with a car dealership for your car to be on their lot, for them to market that car and arrange to sell it. You retain title to it.
If that dealership then goes out of business, sells your car to someone else, and doesn't pay you for it, they have committed theft. Criminal theft, not some sort of civil thing.
The same has happened here. Possession of guns was transferred for consignment purposes, but unless ownership transferred, then the guns were sold illegally and have been stolen. Theft is a criminal issue, not a civil one.
I agree with the person above who said to start contacting every law enforcement agency possible.
