Jill and her father were taken to the police station for questioning the day after the murder of her mother, Denise. Neighbors had reported hearing a fierce quarrel and sounds of a struggle; Denise's body was found the next day in another part of the apartment complex. On the basis of Jill's statement and her father's questioning, her father was arrested and charged with murder. Jill was returned to the custody of Eva and Joe, who had previously served as her foster parents. Since the murder, Jill had become anxious and active and was suffering from night terrors and bedwetting; one month after the murder she was taken for treatment. The goals of the treatment were to relieve her suffering by eliminating her symptoms; to restore her psychological equilibrium; and to minimize the risk of future psychological problems resulting from the trauma. A number of theoretical and clinical concerns impinged on the achievement of these goals, including work with the foster parents, posttraumatic stress, mourning, identification and aggression, and termination. Because restoring psychological equilibrium and minimizing long-term harm were of paramount importance, Jill's clinician prevented her from testifying in court. Clinicians treating children who have witnessed parent-parent homicide must confront complex thereapeutic and case management issues. Included are 33 references.
