S17, E5: Carl Mullaly (guest star A.J. Handegard) is found dead in his Upper West Side apartment after being "outed" by the news magazine series "Hardfocus," which was trapping suspected pedophiles by having staff members pose as young girls. Detectives Ed Green (Jesse L. Martin) and Nina Cassady (Milena Govich) quickly suspect Mullaly’s neighbor Andrew Fleming (guest star Remy Auberjonois) because he has an eight-year-old daughter, but his alibi checks out. Fleming’s daughter claims she saw a woman with Mullaly, who she identifies as his ex-girlfriend Hannah (guest star Zoe Lister-Jones) in the police lineup. Hannah claims self defense and it's up to A.D.As Jack McCoy (Sam Waterston) and Connie Rubirosa (Alana De La Garza) to convince the "Hardfocus" producer to reveal the true culprit and motive. S. Epatha Merkerson and Fred Dalton Thompson also star.
