From the evidence it seems that the hacker knows his real identity. The hacker gained access to Satoshi's "real" gmx email address which then had his satoshin@gmx address as an alias. If this is true the real Satoshi Nakomoto's identity will be soon revealed. We have been able to cross reference the purchase order to a bitcoin talk thread https://bitcointalk.org/index.php?topic=193129.0 around the exact date so the email looks legitimate.
So the guy who hacked the gmx account also ordered an FPGA. Nothing on that Cardreaderfactory invoice has anything to do with the creator of bitcoin.
in that case, either the hacker or satoshi is in missouri. i have no idea which it is, but man.. would satoshi really use his personal address on that account? that would be a ross ulbricht level mistake.
