Since you've discovered law enforcement isn't interested in enforcing the law, you need to set up your own sting and get the scammer to show up where you can arrest them after they commit a crime in your presence.

The scammer will show up to a bar in Bucharest. They are probably not even legally allowed in the U.S.

None of this scam requires the scammer to be in the U.S.

Even the New York driver's license, even if it is real, could be muled. More likely it is just a photoshop.

And even if they do show up to the meet, what are you going to do? Call the police? Will they even show up quickly? When they do, whose photo ID will the believe? Seems like a good way to spend a night at the station while the police sort some things out.
