In the future, consider being the "shipper" when you buy something since UPS only reimburses the shipper. This is all the more prudent if you, as the buyer, will be paying for the shipping in addition to the price of what you purchased.
Also, I believe that UPS takes back the package from the receiver and sends it back to the shipper. If they only took pictures, and didn't take the box back, then I'm not sure if they re-imbursed the shipper. And finally, who initiated the claim with UPS? I believe that the shipper has to initiate the claim. If this guy initiated the claim, and then disappeared, then he may well have been reimbursed and got paid twice- once from you and once from UPS. If that's what happened, he is a very bad man. Maybe we ought to gather some "audiogon posses" in each major city to act on behalf of audiogon members and visit with these guys to encourage them to do the right thing.
