Sally Maxwell was a high school girl and a suspect in a school shooting involving three high school boys responsible for gang-raping her mentally-handicapped sister Valerie, which she committed out of revenge when the boys' guilty verdict was overturned by a judge's overrule. During the shooting, she accidentally wounded a teacher.
She was sentenced to a year in a juvenile facility for women for her culpability in the shooting. (L&O: "Damaged")
