Is there a refugee girl by names of Sandra Hassan from Congo in Senegal camps?

There is an "advance fee" or "419" scam that involves a supposed girl in Dakar Senegal who needs some money in order to gain access to even more money, or escape, or relocate, or meet with the person being scammed.

If you send any money at all, you will have lost the money. You will not meet "her", or help "her" out of the alleged camp, or whatever else "she" has told you.
