I think i have a good guess of what this guy did as well. Just need to find a way to catch him. What do you think?

1. Guy hacks an ebay account with keyloger or w/e.

2. Changes the account information with an adress to an unoccupied house.

3. Conviences seller to overnight payment.

4. No one is there to recieve the package so the postmaster leaves a notice.

5. Takes the notice the next day to the postoffice to sign off for the pack.

6. He's home free with nothing to trace back to him.
