Get a hold of a local TV station or newspaper near his residence. They usually have an investigative team that just loves this kind of stuff. Always looks good for their ratings.
MAN I LIKE YOUR THINKING! Call one of the local news people. I think they would be chomping at the bit for a front line story. Give them all the people you know got scammed and I bet others would come out of the wood work. MAKE HIM FAMOUS!
Now days this will cost you everything.
