Elaine molested both June and Katie, and June never forgave herself for not saving Katie from their mother. As an adult, June earned a living as a piano teacher. Later, Katie molested and murdered one of June's students, a young girl named Marnie Owens, and June reluctantly helped her and Elaine dispose of the body.
During the investigation, June takes the blame for Katie's crime and tries to commit suicide, but Benson and Stabler save her. During an interview with Dr. Cap Jackson, June insists that she committed the murder, and that she was abused by her late father. When Katie confesses to the murder, however, June admits what really happened. She then enters therapy with Jackson, who promises to help her. (SVU: "Totem")
