Guys, if you are still in on this, I would recommend that you find a way to set up a board off this forum to maintain contact, and get counsel in the area of consumer protection and fraud involved. It will be a federal case and lots of lawyers are going to run from it, but someone will listen. There is a lot of money here, and you are going to be praying for just some of it back. You only hope there is cash in an account somewhere. If not, you are going to need additional help.....
....which brings me to the next and more sure point. The authorities need to be contacted. My guess is that this is FBI jurisdiction, but you might start in their own backyard and contact the local PD or Sheriff's office in his county. The time is now. Let them flush the rest of it out. The story makes allegations of theft and fraud, on a knowing and continual basis. There is a substantial amount of money involved. These are allegation that, if found true, result in federal prison sentences and seizures and asset forfeiture.
I would at least demand that that futon his mom was bragging on them buying be sold to refund you. That's your futon. His mom told anyone that would listen as much last year at TPF.
