Lost Traveler

S13 E9: A Romani child disappears on his way home from school. Benson (Mariska Hargitay) and Amaro (Danny Pino) interview the distraught parents, who are distrustful of the police. The initial investigation leads Fin (Ice-T) and Rollins (Kelli Giddish) to the powerful leader of the Romani community, but he denies any involvement. The family remains hopeful their boy will be found, especially when they discover his cell phone is still active. With the help of their TARU tech (guest star Gottfried) and a meddling newspaper reporter, the detectives narrow the perpetrators to a mentally challenged neighbor, throwing the tight-knit Romani community into turmoil. Also guest starring Ron Rifkin and Gavin Lee. Also starring Dann Florek (Captain Donald Cragen) and Richard Belzer (Sergeant John Munch.) Special appearances by Stephanie March (ADA Alex Cabot), Tamara Tunie (M.E. Melinda Warner), and Linus Roache (Bureau Chief Mike Cutter.)
