Law & Order: Criminal Intent: Season 3, Episode 9

3 - 9: Happy Family

The bludgeoning of a rich family patriarch has the detectives investigating several suspects, each with their own motives: his estranged wife whom he was about to divorce, a male friend of hers who was a parolee, their children's nanny, the victim's brother-in-law who is a doctor, even the oldest son. Goren and Carver call the family of suspects together to sort it all out… in family court.
