Jennifer "Jenny" Brandt was a young girl who, at the age of ten, tortured and murdered eight-year-old Aaron Polansky. She was tried for the crime, but she was exonerated and released to the custody of her mother, who is required to attend monthly appointments with the judge.
While evaluating her, Dr. Emil Skoda theorizes that she was emotionally and perhaps physically abused, and that she exhibits several indicators of sociopathic behavior, including a history of animal abuse, flat emotional affect, and fantasies of violence. (L&O: "Killerz")
