I was contacted by user Alimamusah21, by emai. We the switched over to chat on hangouts. She asked about meeting up and told me she needed a little money to get plane ticket. I sent $200 to a male third party in Ghana which I is where she said she was. The. I was asked for more money. A few days later I got an email from her family's lawyer that her late father had left a fortune in gold dust to be administered by her man. Then he requests money to process the documents. After that I was asked to send money to pay for the shipment. At this point I refused to send any money. The next day usera6029 contacts me with pictures and an embarrassing video and demands $3000 or the video is sent to my wife. I paniced and went along well the transfer was supposedly covered by the police and the receiver of the blackmail mo ey was shot in the leg. Later that night I get pleas from Alimamusah21 to go along with the blackmailer again just to get him out of our lives. Usera6029 sends me another email demanding another $3000. I counter offered and he brought his demand to $1800 which was due yesterday 5/10. I haven't paid it and won't pay it, now he has given me till Friday 5/13. I don't have any documents to provide other than emails from usera6029 and chat with Alimamusah21 but the chat history only goes back a few days.
