Joyce Draper is a prison therapist who was assigned to domestic abuser and child killer Jacob Lowenstein, even after his release from prison. She was horrified upon learning that the child of Lowenstein's fiancé Sheryl had a broken arm, and she feared that Lowenstein was back to his old habits of child abuse.
Draper tracked Lowenstein down to the school he dropped Sheryl's children off at. There, Lowenstein was struck by a car before the driver sped off. Lowenstein lost his leg and then died due to his injuries. Draper was identified as the driver and taken to trial, but she was acquitted based on reasonable doubt. (L&O: "Fixed")
