Delilah Evans, 17, has been charged with First Degree Premeditated Murder in the stabbing death of her mother.
Another relative found the body of 45-year-old Sonia Riang on Christmas Day in her Clinton Township apartment.
Riang was disabled and confined to a wheelchair after a car accident years ago.
Evans is now being held without bond in the Macomb County Jail.
Though it appears she has never been diagnosed, relatives say the teen is battling mental health issues.
Police say Evans fled the apartment after the homicide. She was located and arrested at a nearby 7-Eleven.
Her brothers say she recently talked about having a dark angel, hearing voices, and claim she talked about someone killing their mother on Christmas Day.
