Benson and Stabler investigate the brutal murder of a teen found in a car trunk. The detectives learn the victim was a popular girl who was bullying a classmate, but suspicion soon turns to her clique of friends. The motive is jealousy over a boy, and the other mean girls turn on the queen bee who put them up to the killing. While Novak gets justice in the courtroom, the bullied student gets instant justice in the classroom. We're talking about Special Victims Unit season 5 episode 17 "Mean." Our returning guest is Sonia Sells. This episode is inspired by the brutal 1992 murder of twelve-year-old Shanda Sharer.
