Efren Saldivar is a documented serial killer, referred to as the 'Hospital Executioner'.

Angel of Death in the garb of a respiratory therapist murdered 40-50 patients. There was talk around the hospital about the night shift and the "magic syringe." A few workers had their suspicions. When staff members are alone with patients and no one else is around, they're free to do as they please. Were these "mercy killings" — trying to painlessly end the lives of dying patients? No, this was a man who liked to play God and decide when someone should die.
