First off thanks for serving our country, and sorry about the scam. What you could do for at least me to attempt to track this guys down is post more information. You say you have emails? Post the header information ex: the ip the email originated from. Post any other information you may have also anything is helpful. I'm not sure if this post will get moved or if you are aloud to post this info so to be safe shoot me a PM with all the information you can.

Who knows what could turn up but these would be the steps I take in a situation like this.
