Parents' Nightmare

S16 E22: 8 year-old Owen Farhidi (guest star Kaeden Ruparel) disappears from school and his mother Dana (guest star Brooke Bloom) receives a ransom request. When surveillance footage shows that Owen recognized his abductor, Detective Amaro (Danny Pino) works with Dana and her ex-husband Sam (guest star Navid Negahban) to find and arrest the suspect, but tensions between the estranged couple obstructs the investigation. Meanwhile, Sgt. Benson (Mariska Hargitay) is asked to take the Lieutenant's exam to formally take the lead over her squad.
