Can I get arrested for receiving nudes from a 26 year old that turned out to be a supposed 14 year old?

I was contacted on a dating website by a supposed 26 year old girl. She requested money so she could get her car fixed and come back home. Well I forwarded her some money, well it eventually turned into lending $5000 with the promise that it would be paid back once she gets back home. I asked her for some adult pictures because we were chatting about things, as adults do, and she sent me a couple. I am now getting a message from her "supposed father" that the girl is actually 14 years old and that I have to send another $1000 or else he will report me to the police. Once I heard that she was 14, I immediately deleted that whole conversation with the NSFW pictures. I had no knowledge that she was a minor (or if she even is one). The people that took this girl in have not let me contact her and her phone has been turned off, so I have no way of getting more information.
