Friend Involved Me In A Possible Scam Without Me Knowing, What’s My Next Step? (tx)

About a month ago a I received a random Zelle payment of 5000$. A friend then blew up my phone saying he sold his car and wants me to cash app him the 5 grand. I thought it was a really weird way to go about selling the car, but I didn’t want a random persons money sitting in my bank account and I thought I can trust my friend so I sent him the money.

A week later, a guy from Florida called and said he hasn’t received delivery of his new Cadillac after putting the 8k down payment (my friend drives an older BMW). He said he understood that the person he sent the money to (me) was not involved in the transaction of the car at all, but if he were to report a scam/fraud crime it would link back to my bank account. I called my friend and told him he needs to figure his shit out, either send the guy his money back or deliver the car. The Florida man called me back and said thank you and that they’re in touch and figuring it out.

I told my friend I want nothing to do with this and I broke off contact with him for breaking my trust since then. We’ve texted the occasional holiday greetings but that’s it.

Today, I received a call again from Florida man claiming that my friend is stalling, and that he just wants his refund of 8k. He says he has a contact in the local police department and will reach out soon if he doesn’t get an answer from my friend. I explained I have nothing to do with this situation, and that I haven’t spoken to my friend in a month. He understood, but still believes I am possibly liable since the bank account he sent it to was mine. I called my friend again and he seems like he’s stalling, giving bullshit excuses about “you don’t understand the whole situation” and to “give him time”.

I am really frustrated, and frankly a little afraid, of what my friend dragged me into with this entire situation. I just started a decent job and am just starting to feel like I’m getting my life together. I live in a different city than my friend and I don’t know whether the car is real or not, or what he did with the money. I feel bad for the man in Florida for losing his money, but I don’t have the cash on-hand to just repay him and figure this out between my friend and I. I would really appreciate if someone has any advice on how to go about this.

Thank you in advance.
