S5, E19: Students at the University of Denver spot very threatening messages in a chat room. They are coming from Jeremy Ostilow (James Colby) in NY. Benson (Mariska Hargitay) and Stabler (Christopher Meloni) go straight to the Ostilow residence and discover it's young JJ (Shane Haboucha) who has been online. The Detectives bring him in; afraid he'll hurt his 5-year-old sister. JJ seems to be disturbed, mutilating the genital area of his sister's dolls and having behavioral issues at school. He was in a fight and screamed rape, so they believe he's been sexually abused. JJ confesses he was abused in the Treasury Room by his dad's old boss, Billy Tysen (Will Keenan), a toy mogul. The Detectives investigate Tysen and find out he lives in a Sutton Place mansion, which is more along the lines of a kid's paradise. Tysen claims he loves children and would never do a thing to hurt them.
