Since you never shipped the merchandise there was no crime committed against you - therefore you wouldn't be able to prosecute. You could turn the information over to the FBI though. The bank has probably already done it, but it won't hurt to have a second person saying the same thing. Contact your local field office, AND the field office that serves the area where the check was drawn. The crime was committed against the bank and the true account holder, so they would have to be the ones who could actually get an investigation started but at least the FBI will have your name and info if they need a statement from you to help bust this guy - providing of course that the Uganda authorities are willing to work with us.
