Fallacy

S4 E21: A party is out of control and after a loud crash in the bathroom, the hostess finds Cheryl (Katherine Moenning) beaten and bloody, and Joe with his head crushed. Paramedics arrive, and the story seems pretty cut and dried. Cheryl claims Joe tried to rape her and she hit him over the head with a vase in self-defense. Joe dies shortly after arriving at the hospital, and Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) question his brother, Eddie (Chad Lindberg) who is Cheryl's boyfriend. Eddie has a heart condition and had been at the party but left early to get his meds. They discover he had returned and figure he caught Cheryl and Joe together and perhaps in a jealous rage, killed his brother. But Cheryl sticks to her story.
