Law & Order: Criminal Intent: Season 5, Episode 7

5 - 7: In the Wee Small Hours (2)

Conclusion. A visiting Iowa teen disappears during her New York City school trip, prompting a massive media frenzy that engulfs Detectives Goren, Eames, Logan and Barek when their prime suspect Ethan, is a powerful judge's son. The case widens when it appears the accused's philandering father Harold, is a co-conspirator who acted to protect his son -- and might be a murder suspect himself -- but he is not afraid to punch back hard against the investigators.
