I don't know about anyone else but I'm not real clear on your post. Do you want to give a little more information please.
Are you saying nothing (no gun) was found in your bags?; if not in your bags, where was it found?; gun was in someone else's name & charged someone else for the gun?; who called you 3 days later?; who is the him/he that will put a warrant out on you if you don't talk to him?..........
Thanks.
