If, on the other hand, it's a significant sum of money then I'd figure out whether or not you have enough info to track him down. Small claims court may be an option if you've got a way to serve him and you deem it 'worth it'.
I`m sure the OP has a buisness where he can just be like,"Oh I made a bad investment...Lets write it off."
As the others have said, Fraud is fraud.
