We clearly see a single transaction to evolution6 :
2009-10-06 21:42:40 To - evolution6 -10000 Transfer
=
2009-10-06 21:42:40 From - shevaroller 10000 Transfer
This transaction must be the first part.
You said you've sent the other half, which cannot be seen in your Transaction History. So, it can't be an error of name or whatever. evolution6 didn't get his TC, you can check his transaction history.
