Pure

S6 E18: Roni Sellers (Marianne Hagan) is horrified when she calls her daughter's cell phone and hears screaming and a man's voice. Kaley (Molly Bea Spears), 18, works as a bicycle messenger to help pay her tuition for NYU. She's a good girl and a good student. When she disappears, a high profile case ensues. Mrs. Sellers holds a press conference and offers a reward for Kaley's return, and tips start coming in as to her whereabouts. Sebastian Ballentine (Martin Short), a psychic, also arrives at the station, and claims he's had a vision of Kaley. Stabler (Christopher Meloni) thinks he's a fraud but when he gives them specific clues, they think he could be a suspect.
