I don't know but I remember reading somewhere that if Bitcoins are obtained illegally, the bitcoin devs can disable those coins, is this true? At least the hacker wouldn't win anything with this.
Anyways good luck friend. Apparently there is no justice in Bitcoin

Every hacker/scammer always runs away with their Bitcoins and they are never punished!
That is wrong and I shall add fortunately. Devs can not disable or return the coins. This is one of the foundations of bitcoin and one of the reasons of its success. If there is a change that will allow devs (or government or law enforcements or mafia or public vote or whatever) to to this, I will migrate to the coin which supports "strong property" and many will do likewise.
Although I sympathize with the OP, Bitcoins are build on the principle: Whoever owns the privkey, owns associated bitcoin balance. This is very important principle.
Your only chance is to find the thief and force HIM (or HER or they) to transfer bitcoins back. No one can do this on behalf on him. In ideal case (thief is known and proofs are clear) police and law should help you to convince him. There are cases scammers were punished.
