Control # 2 lists a PayPal receipt with the email address knightmb@endless-sphere.com.

In June this year, he posted on the Bitcointalk forums that he'd lost/given away the 371,000 BTC he'd "acquired" from his previous employer for $5,000.
The only thing I have left is old screenshots and empty wallet files now.
