TURF WAR BETWEEN DISTRICT ATTORNEYS MAY COMPROMISE JUSTICE IN MURDER CASES -- When a woman is found strangled to death with a large quantity of the drug Ecstasy in her handbag, Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) have difficulty gathering sufficient evidence for an indictment of their prime suspect, drug-dealer Francis "Taz" Partell (guest star Peter Greene). But when they question one of his former associates, they discover new evidence indicating that Taz is responsible for the earlier murder of a bouncer in Bronx county -- a murder for which another man has already been convicted. A.D.A.'s McCoy (Sam Waterston) and Carmichael (Angie Harmon), with the help of D.A. Lewin (Dianne Wiest), have the tricky task of convincing the Bronx District Attorneys that they convicted an innocent man, while seeking an indictment for Taz.
