tracking a criminal down electronically
dkokelley: What you would need to do is see who provided phone service to him and then get the information on address and billing through the provider (requires warrant). Also, did he use a public email (yahoo, gmail) or was it through a private site? You could try the whois to see who the host is and contact them too. I agree with pierrefar that the best course seems to be hiring a PI.Or...You could post what you know up here and round up an HN posse.Edit: That last line is sarcasm. Don't really do that.
