Evidence against:
- As Blazr mentioned, wallet stealers often wait until a significant amount triggers them into action and this address hardly had more than half a bitcoin in it before the day in question.
- This person should have known that he would be the first suspected and that his victim could easily track him down.
Yes, if he is really a thief, he is very stupid thief. If he would wait for several days before cash out, first of all, OP would not suspect him, and second, OP could put a couple of btc more to his compromised wallet.
