Google 'Private investigator malaysia' and you'll find a number of PI ranging from ex-police officers and military if u willing to pay a small amount to track the conperson down.. there used to be a case here quite a few years back when a bunch of people who were conned actually chip in to hire 1 and they did track him down.. they then got a lawyer to issue the summon to the guy and went to court.. not sure what happened after that...
