S7 E12: Gordon Clapp, Judith Light and Annie Potts Guest Star -- When a woman is found shot to death in her apartment, Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) discover 14-year-old Nathan Phelps (guest star Malcolm David Kelley), traumatized and hiding in the closet. The investigation leads the detectives to Ted Carthage (guest star Clapp), the head of a charity organization, and whose voice Nathan recognizes as belonging to the man who shot his mother. Without a positive I.D., Carthage is released, but later found dead - shot by Nathan. A.D.A. Novak (Diane Neal) must prosecute Nathan and attempts to give him a break when his attorney Sophie Devere (guest star Potts) finds a study that suggests people who witness gun violence are more likely to commit acts of violence themselves. But their plan to settle with a plea is disrupted when a gun manufacturer's advocacy group catches wind of the defense, fearing legal implications. Dann Florek, Richard Belzer, Ice-T, B.D.
