Unfortunately, I only returned to this topic over a year after Guinness1759 posted his request for help.
I am willing to help, if you are still trying to recover lost money ; but when I click the "send an e-mail" link on your profile, the software tells me I am prevented from sending a message, and I don't want to post my own personal e-mail address here.
I sent a message to the moderators, asking if there is any way they can connect me to you.

ebay ID is still live. His feedback list shows about 10 adverse comments for being a non-paying bidder, and one accusing him of robbing a seller (which may of course be from Guiness1759).
I never received any reply from the Police station in Saint Cloud, which may be due to the fact that I'm not a US citizen, or that they aren't interested in investigating online crime.
