if you don't mind me butting in here sad to hear of your loss,i would try and gather any info u have and report it to local authoritys as soon as you can,lot of scammers out there.
u must have some form of id on this man or recipts to show.
i remember actually hearing of a guy in a similar situation to you before but he done the opposite thing the crook pretended he didnt get the item that was sent to him to claim the insurance on it,it backfired though on him.
sad state of affairs,not being smart but i would have done the deal in person,even if it meant paying flights,ye could have sorted something like.
anyway best of luck to you,thats a fair nasty thing to do......
