Jill Jennings (born Gwen Colter) was a fashion designer who persuaded her lover, Terry Briggs, to kill her own sister out of a personal grudge against her that she held from her childhood.
History[]
When Jennings and her sister Lily were children, their mother was a crack user, and they were both placed into foster care until she got clean. However, their mother couldn't afford to provide for two daughters and thus chose to retain Lily, the youngest, while leaving Jill with her foster parents, angering her and causing her to develop a grudge against Lily for years. She eventually entered in a professional relationship with her: Jennings was a fashion designer, while Lily was a movie star stylist. As a means of ruining her sister's life, Jennings seduced Lily's husband Douglas Cantu, hoping it would have ended their marriage, but to no avail. Lily later ruined Jill's reputation in the show business, forcing her to move her boutique from Beverly Hills to Los Feliz, fueling her anger even more. Having fallen into a deep depression, she resorted to Terry Briggs, a former police officer and her lover, asking him to murder Lily as a romantic gesture towards her. Briggs accepted, and he shot Lily five times with a revolver when she stopped her car at a traffic light while heading to a dinner with Khloé Kardashian.
Eventually, while investigating Jennings's job relationship with Lily, Detectives Morales and Jaruszalski managed to get to Briggs, who confessed to the murder and admitted he was prompted by Jill. Despite this, a prejudicial past job relationship between Morales and Briggs was brought in court by Jennings's attorney, thus preventing D.D.A.s Dekker and Rubirosa from bringing her to trial. Jennings was again arrested when evidence emerged indicating she had participated in the murder by secretly inviting her and Lily's mother to a fancy party, so that Douglas would have remained at home with Lily's daughter Kathy on the night of the murder, instead of going to the dinner with his wife. During the subsequent trial, Briggs committed suicide in order to force a mistrial and save his lover. In the end, Dekker and Rubirosa found out the truth about Jennings and Lily being sisters, and they organized a confrontation with her mother, during which Jennings confessed to the murder. She was then sentenced to fifteen years in prison to life. (LA: "Benedict Canyon")
