Kim Triandos is the widow of philanthropist Peter Triandos and a suspect in his murder. She was acquitted at trial and sued originally by Peter’s assistant, Robert Mallors.
It’s revealed her mother, Velma Darcy, and the family lawyer, Oliver Shain conspired to kill Peter for his inheritance. Once Darcy and Shain were arrested, the lawsuit against Kim was dropped. (L&O: "Matrimony")
