Call the local police and file charges for felony level interstate fraud.
This is the appropriate action. Results will come from this.
I personally don't think anything would come of this if the police were called. The police likely do not have jurisdiction over where the scammer lives and it would be argued that the crime was committed where the scammer lives. Additionally the amount in question is very little and most police forces do not have the resources to be investigating crimes of this magnitude (or lack thereof).
I wish it was not this way, but I am just giving my opinion.
