JR,
I think you should be proud of yourself for assisting the retrieval of the items as well as stiffing the thief from his ill-gotten gains. I sincerely hope FedEx & local law enforcement follow up on the theft & prosecute as it sounds like there's sufficient evidence for some sort of action.
I feel were it not for the good deeds of you & some others as well as a lot of luck, the items would have been sold off never to be seen again. Not that you're looking for anything, but an emailed "thank you" seems a bit impersonal.
