I meant they could get interpol to trace his IP address if they really needed to... I'm sure they could honey trap him somehow... the guys behind Labcoin weren't very smart and he probably isn't a hardened cyber criminal either.. just a regular guy hiding because he knows he is in shit for helping to promote a scam... BTC-E is a well run and secure site but that doesn't mean the people who use it are good at hiding and covering their tracks.

anyways as you already pointed out.. there are probably easier ways to find the guy...

if worst comes to worse someone can go to the press with this story.. just look at Mt GOX they are eating up that story because it gives them a chance to bash Bitcoins.
the banks /press/ and police are all over it.
also italy is the home of the paparazzi... if the police cant find Alberto and his friends.. im sure some  paparazzi press guy with a scooter could if the story was juicy enough lol
