The Third Guy

S1 E16: 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.
