HIGH SCHOOL LOVE TRIANGLE TURNS DEADLY -- When a female high school English teacher is found stabbed to death, Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) uncover a love triangle with both a scorned 16-year-old (guest star Stephi Lineburg) and her faculty lover (guest star Rob Campbell) as prime suspects. Executive A.D.A. Jack McCoy (Sam Waterston) and A.D.A. Serena Southerlyn (Elisabeth Rohm) hope to turn the two lovers against each other in order to shake loose a confession, but find their love unbreakable.
