CC Theft

I know someone who used my CC information to steal. It's not a huge amount. A couple thousand dollars, credit card fraud. Macy's Wisconsin. The CC company canceled the card. I'm out zero money. I know who did it. NOW the question is since I am out nothing, what do I do? Let the authorities and the security cams take care of it? I suspect they will. Macy's didn't just fall off the pickle truck. When this happened I asked Holy Spirit to tell me if I needed to know more about this then I did. Now I do. I don't know if I have any part of exposing this person. HMMMM
