I strongly urge you to call the Police Department in his town as I suggested earlier. Its a small town and I bet they know him. Maybe a detective will go down there and have a chat with him. Its worth a phone call.
If a detective were to approach him and start throwing terms like "internet fraud", "felony", "theft by deception" etc etc, and suggests he square up with folks like you (especially if the detective can provide a name and a parts list) it's possible that he will fix the problem.
It's certainly worth a try.
I also noticed on his FB page that he made a comment about the Chillicothe Police having their own page and accused them of spying on people. That's paranoia and guilty conscience talking right there.
