Reminds me of when some douche in DiII:LOD stole a bunch of elite uniques / special crafted items from a friend of mine and tried pawning them off on some other people.
We handled it as you should in an online game where items are traded or found etc...etc..We had some friends track the guy down. Ended up taking his accounts and getting his stuff and our stuff back
Then, we had blizz shutdown his accounts. Why on earth would anyone kill someone over something online? Nevermind, don't answer that

. Again, I'd post my retard award but my server is temp. down.
