If the local authorities can't do anything then there are some things you can do to take a couple matters into your own hands. Where ever you first found this guy advertizing, post BOS (Beware of seller) warnings. Web classifieds, craigslist, face book, everywhere. If he is going to make a business of abusing animals, make sure he never gets business. When you do, be sure to include as much information about your transaction as possible; name, contact info, his whole operating MO. He sold you a thin, dehydrated normal as a healthy mojave, that is a man who shouldn't be anywhere near the herp hobby.
