William Charles Mitchell

The parents of a missing college student seek help; David gets help on the Cytron case from an unexpected source; Mellie proves her political prowess.

Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) lead the investigation into the sexual assault and possible murder of an elderly woman, and their scanty leads point to two neighborhood toughs (Eugene Byrd and Rick Gonzalez) who will only admit that they broke into the victim's apartment as thieves. When the lack of evidence forces them to grudgingly cut a deal between the two, the detectives only then learn that their most likely suspect for the rape has been right in front of them all along. Richard Belzer, Dann Flore and Michelle Hurd also star.

When Reid fears his mother has been abducted, he asks the BAU to investigate while he's stuck in prison.

Carlos and Gaby get temporary custody of baby Lily, Bree's father and stepmother come to town to mediate between Andrew and her, and Susan suddenly finds Karl back in her life.

When a Marine is murdered at an event for the Honor Flight Network, a non-profit that arranges for veterans to visit the World War II, Korea and Vietnam War Memorials for free, the NCIS team must rely on an irritable Vietnam War veteran, Henry Rogers (Bruce McGill), to provide details on the victim's whereabouts throughout the day. Also, McGee and Bishop investigate a juicy rumor about Quinn and Torres.
