A woman at my bank did the nasty with an illegal, now what happens?

A not to attractive customer service representative at my bank, believed the Latin lover lies and then copulated with a Mario Lopez clone.Now she has taken down his array of muscle pictures from her cubicle.She is within a week of having the baby either naturally or by Cesarean and won't speak about him. The other woman at the bank said he was missing for over a week and was not at the construction job site he was cashing his checks from.How can this person obtain child support if she finds him.
