Sounds like a scam for the woman to get welfare and not cost the father anything.
Notice that every time the guy had a chance to go in and sign some official document or swear that he wasn't the father in a court of law he failed to do so.
His evasiveness suggests strongly that he's guilty of impregnating this woman.
Ecxuse my lack of tact, but besides reinforcing the notion that you didn't read the article, you are reinforcing the idea that you are pretty stupid. The mother has named another guy as the father, and she's had a second child with him.
Just for giggles, why don't you explain how that scam would work?
