You're likely not in any trouble for anything other than the bounced check fee. If it was me, I would call the local PD and report the scam. This will also help establish that you aren't a part of the scam.

You need to pay back the check casher or face possible consequences. Obviously, whoever cashed the check is not going to eat the loss as there too many of these scams going on.
