Grace Rinato is an abusive mother of her children, two of whom she murdered when they were still young.
History[]
Grace grew up with her mother Rose after her father left them. She was apparently abused when she was young and became a sociopath as a result. As an adult, Grace killed two of her children, Anthony when he was an infant and Lisa when she was two, because she couldn't handle the responsibility of taking care of them and hated when they aggravated or displeased her by crying. When her second murder was discovered, she tried to pin it on her third child Claire, who was spared because Rose protected her and cared for the children more than Grace.
In order to save Claire from imprisonment, Rose testified against Grace by revealing what she knew about the first murder, which she had been a witness to. As a result, Grace was sentenced to life imprisonment. (SVU: "Denial")
