What do you know about Nurse took in Disabled teen then killed her?

 A mentally disabled woman was taken in by a nurse. She thought that she would get help and care from this woman, but instead for years tortured and subjected her to horrific abuse. Eventually the nurse killed the 23 year old girl. She had burns on 25% of her body, a deformed ear that had been cut and bruising on her face and upper torso. This would fall under both the psychological and biological sections because it has to do with behavior and mental disability.https://www.nbcnews.com/news/crime-courts/illinois-nurse-took-disabled-teen-then-tortured-killed-her-police-n1080546
