If all who have been defrauded and used the USPS filed a complaint with the postal inspectors he might be thrown in jail. Using the post office makes it a federal felony and the post office has its own police force to deal with people like this. I would contact the post office in his home town and suggest on other boards that people do the same. anyone can make a mistake, this guy is a crook, he isn't making mistakes he is a conman.
