S5, E16: A young, emaciated boy is found by neighbors scrounging for food. Benson (Mariska Hargitay) and Stabler (Christopher Meloni) suspect the boy, Jacob (Jesse Schwartz), is a victim of abuse and are reluctant to let him go home. They question his mother, Marilyn Nesbit (Diane Venora), and she seems strange. It appears she controls Jacob with food and is very restrictive about what he can eat. Jacob and his teenage brother, Adam (Joseph Cross), are both home schooled and their house is immaculate. Their father was killed in a random hold up and it appears Marilyn just wants to keep her boys close, at home. However, there isn't enough to prove Marilyn is an unfit mother so Jacob returns home. Stabler gives him his card, and says to call if he needs anything. That night, Stabler's cell phone rings, he knows it's Jacob, but by the time he gets to his apartment, he is lying in a pool of blood, dead, and Marilyn and Adam have disappeared.
