IF you are lucky, the best you will get is a good lead into where to look. Example, if you got your wallet stolen and that person cashes out by selling your BTC to someone for cash, you can look into the other user. But BTC is meant to be anonymous, yea there are cracks into it by getting traced, but it's hard. If they washed the bitcoins that they stole, your completely out of luck unless you wanna check over 5,000 addresses.
