There have been some reports locally (I found out from a colleague who speaks to the Leesburg Police from time to time) of the re-emergence of a popular Lottery Winning Check Scam. If you receive a letter in the mail, with a check, saying you won a lottery, please be cautious! FraudAid has a ton of information to help identify the scam. The bottom line is this:
If someone unknown to you asks you to wire money somewhere, don't.
