Details: Marianne Malky had a son named David Shipenburg whom was abducted by his father, Steve Shipenburg in May of 1974. Steve and Marianne had divorced in December of 1973, and she received full custody, while Steve received visitation rights. While she was in a New Jersey hospital, Marianne left David with her sister when in May his father Steve took him to New York for a routine visit. That night, Steve called Marianne and told her that she would never see David again. When she was released from the hospital, she went to New York to find David but to no avail. However, a month later, David called Marianne and he was apparently crying; she told him that she would find him.
