Is this child support fraud?

My friends wife walked out after 9 years and took the kids with her. During divorce court the wife claims one of the kids is not his.(DNA now confirms this) Can he recoup support of the child for those years since she lied the whole time? Is that a form of child support fraud? If not, is there anything he can do according to Ohio law?

FYI, she went back to the supposed father of the child. He is also representing himself because he is on disability and can’t afford an attorney.
The wife was pregnant before marriage. That’s one of the reason of getting married.
