He was never part of my son's life. He is deliquent in child support and is abusive . He wrote me on facebook from someone else's account stating "This message is from a friend. You should of did it a couple of years ago when I wanted you to, but you were greedy and lied to me and did me wrong. If you really want those papers signed so bad. All I'm asking for is $15,000 to sign them. I already know your answer. So see you soon ". Do I have a chance of getting the adoption papers signed? Since clearly it all about money to him.Do I need to get the police invovled?
