The initial account in the chain belongs to Sterlingnov. However where is the evidence that subsequent accounts belong to him? Maybe he was selling the BTC on Bitcoin-otc or some other random place that existed back in the days, and now he is wrongly linked to the guy. Edit: sorry, missed the evidence about using same IP for both the mtgox and LR account. Weird using the chain of transactions and then doing that kind of rookie mistake.
