List of NYPD Blue Characters - Assistant DA's

Assistant DA's

• Laura Michaels Kelly—The ex-wife of Det. John Kelly in Season 1, they were amiable enough after their divorce to sleep together on several occasions, but finally decided that their pattern of sex and fighting needed to end permanently. Laura was a DA who was pressured by a sleazy supervisor to lie about a dying witness' final words, but she used a recording as leverage to get a transfer to the position where she worked with the 15th's detectives. She told Det. Kelly she had begun dating a doctor (played by Kyle Secor), and later that she felt she was being followed. She then got angry at her ex-husband for interviewing the doctor, and he told her to go ask someone else for help in her final episode, but then confronted the men who were stalking her and made it clear that if she got so much as a cold he would bring the wrath of God down on them.
• Sylvia Costas
• Leo Cohen—A sarcastic young ADA who quickly ran afoul with the 15th's cops for reasons ranging from snidely referring to secret love affairs (Bobby and Diane) to implying widespread brutality (Andy) and bad judgment (Lt. Fancy), Leo nevertheless showed he cared about the law and was able to sometimes work well with the 15th's top cops. He dated Jill for a while but ruined that relationship with his jealousy and its interference in her job. Leo later entered private practice and briefly represented Andy, Diane, and Greg over bogus corruption charges in Season 8, and returned to the DA's office in Season 11 to unsuccessfully prosecute a murder case.
• Valerie Heywood—She became the full-time ADA for the 15th after Leo Cohen left in Season 8. While she was smart and tough, she alienated Andy with her rigid rule-book approach, and often showed judgmental tendencies that Sylvia Costas had generally avoided when dealing with cops. She was attracted to Det. Jones and they dated in Seasons 8 and 9; when she thought she was pregnant and later had a miscarriage, their suspicions and lack of personal chemistry sank the relationship. They resumed dating in Season 10 and Det. Jones helped her out when a man she'd put in jail got out and harassed her, later arranging for a lowlife friend of his to beat her up. After losing a slam-dunk case against a corrupt IAB Captain over Lt. Rodriguez's shooting, she appeared in fewer episodes and was written out of the show after Season 11. Played by Garcelle Beauvais-Nilon.
• Lori Munson—ADA Munson became the full-time ADA in Season 12. She was initially furious at Det. Clark when his actions ruined a murder case, but she later forgave him when he'd cleaned up his act and helped salvage something from that case. They also began dating and were still doing so when the show ended. Her father was a very powerful and meddlesome businessman named Owen.
