As soon as I received this message I knew it had to be a phishing scam. I went to the Atlanta FBI website and got their contact email, then reported this email as suspicious. They replied and said to forward them the email and go to www.ic3.gov. I did that and filled out the form they supplied online, which was very easy. Then they replied to me within a half an hour:
This is a scam in which the FBI has been victimized along with thousands of others. Simply delete. You may also make a complaint to the Internet Complaint Center, IC3.GOV.
I am glad they will track back and get at this jerk, jerks, or jerkesses, or jackesses.
