PATERSON — The man who was believed to have fathered twin girls in Passaic County actually only fathered one of them, according to a precedent-setting ruling by a Superior Court judge. It's the first paternity case in New Jersey and only the third nationwide to feature two different fathers for a set of twins. Judge Sohail Mohammed ruled that a man identified only as "A.S." was off the hook for child support payments to one of the twins after DNA testing determined he fathered one with 99.9 percent certainty but could not have been the father of the other.
