A new lawsuit accuses an Ohio fertility clinic of a sperm mix-up with heartbreaking consequences. Joseph Cartellone says he recently found out he is not the biological father of his 24-year-old daughter after he and his wife used home DNA kits that she had given them for Christmas. The Cartellones said they have since narrowed the possible biological father to a handful of men, including one who worked at the hospital that helped conceive their daughter. Anna Werner reports.
