I have an issue going on. I recently sold a handgun to a co-workers of mines cousin. I've hung out with the guy here and there and he decided to buy my Taurus PT111 from me. I found out today that last night he got arrested for driving w/o a drivers license and the officer found the gun in his car (with an empty mag). I also come to find out the he doesn't have papers (illegal Alien).. so what do I do, I have my bill of sale and everything and the guy showed me his ID when I asked for it but there's a law that says you can not sell to illegal aliens (which I did not know he was). This has me stressed out.. any Advice??
