On October 24, 1998, Kristine Kupka, an honors student at Baruch College in Manhattan, disappeared after leaving her Brooklyn home with one of her former college instructors. Kupka and the instructor had begun a relationship when she was in his science lab, he was the father of the child she was carrying and they had argued over his insistence that she have an abortion. She had told several of her friends that she was afraid of him. He reportedly said he'd driven Kristine to a mall, waited outside in the car while she shopped, then dropped her off near her home. Kupka has never been seen again.
