u have his bank account - good enough. report police and hope the 'international scammer' will get caught. if he was so great, he would be working in some government/spy/hacker or whatsoever with his skills.
if all else fails..get his house address,name, and bring along some parangs to chop off his bodies, part by part.
sorry for your loss.
