Yangdu:
My suggestions for you as a street level bacon bits.
Internet fraud (buyer or seller ) is a significant problem. Because this is an interstate issue, you can contact the FBI to file a fraud report via their website (
www.fbi.gov). Once the FBI receives the report, it is forwarded to the agency at which the fraud occurred. In yoru case, it would be either Reno PD or your county as that was where the deal was transacted, not where receipt of the item was. Because it was a credit card versus the use of a USPS MO, the Postal Inspectors won't touch it - yet.
Sadly, this is one area that business insurers are getting hammered in.
You can also file a fraud report with your local LE agency. The value of the sword plus the act of commiting internet fraud (provided your state has those sorts of laws on the books) would probably place it into either a gross misdemeanor or low level felony, depending on the state level for value and criminal act. If an agency is interested and the item is readily identifiable, action can happen. Here is an example (and I've done a few of these before):
You contact Reno PD and file the report. The report moves to the detectives, likely those assigned to fraud cases. The detective processes the case and contacts his/her peers in Florida at the receiving jurisdiction. Information is passed. The detectives there open their assist case and being the hunt, provided the desire is there (some agencies may look at this as a low priority). Pawn slips are pulled and pawn detectives keep an eye out for an unusual sword being pawned (most reputable pawn shops are registering their pawns on-line or have state laws requiring real ID to pawn an item). If the sword is found, back trace to the receiver and squeeze them for receiving fraudulently obtained merchandise. Reno PD files charges for fraud although the likely hood of the suspect(s) even coming to Reno to face charges is slim to unlikely (again, the value of the sword).
But here's an odd one for you. I had a case in which a subject received an item but decided to falsely claim his card had been stolen, hanging on to the merchandise he claimed he didn't get. The match of his signature to what UPS captured helped to break him and roll him for more than just this event.
Anyway, those are my suggestions. By no means should you just let it go. The receiver of the item is unlikely a newbee at this and probably has priors.
