|~ Jarrow as she is arrested|
Kathleen "Kathy" Jarrow is the main antagonist from "Betrayed", episode 7.13 of Law & Order: Criminal Intent.
Kathy Jarrow is a former NYPD officer who currently works as a true crime author. She is introduced as the wife of Woody Sage, who is much younger than her; he is her third husband. Kathy and her first husband filed for divorce, and she later married Judge Feld. By that point, Kathy wanted to become a mother, but after learning that Feld was having affairs with male prostitutes, she flew into a murderous rage and killed him. Kathy poisoned Feld's drink with a form of Viagra, which led to Feld fatally succumbing during one of his extramarital trysts.
After killing Feld, Kathy uses her longtime friend, Major Case Captain Danny Ross, to unwittingly cover up the circumstances of Feld's death, while also preventing an autopsy from being done. Kathy later married 23-year-old Woody, who was really a con artist named Scott Woodley, and she planned on having a baby with him. She later began to notice that Woody began distancing himself from her, and at one point, Woody recommended Kathy to a masseuse named Avery Hubert. During this point, Kathy learned that Woody and Avery were illicit lovers, leading to her planning to kill both of them. She hacked into Woody's GPS and tracked the couple to their location, where Kathy took them near a body of water and shot both of them in the head.
In the episode
Kathy plays the role of a concerned wife upon learning about her missing husband, and after the affair is revealed, suspicion falls on Avery's husband Roy, due to his narcissism and history of domestic abuse. Not only does she continue manipulating Ross, but she takes more tracks to cover up her crime, including sending a message with Avery's phone and making it appear that they had run off together. She also claims that Woody had contacted her two days prior, after she is shown preparing her nursery, still acting as if Woody is alive to keep up appearances.
Detectives Alexandra Eames and Robert Goren become suspicious of Kathy, leading them to dig into Feld's death. After the true details of Feld's death are revealed, Goren, Eames, and Ross take Kathy to the last location of Woody and Avery, where Goren and Eames reveal Kathy's entire scheme. Kathy denies everything and even attempts to convince Ross that she is being unfairly profiled. When Kathy accuses Ross of trying to get back at her for turning him down years earlier, Ross realizes that Kathy is a narcissist and a serial killer. She also states that the detectives have no proof, only for Eames to state that they have a body - Feld's. Kathy finally shows her true colors and confesses to the murders, claiming that her victims deserved their fates, after which they arrest her.
