Post Mortem | The Journals of Maria Muñoz

When police respond to a 9-1-1 call at the home of Maria Muñoz, they discover a chaotic scene: Maria, unconscious on the floor, and her husband, a trained nurse anesthetist, performing CPR. Only hours later, Maria is declared dead. Producer Marcie Spencer and 48 Hours correspondent Erin Moriarty discuss how this mother of two ended up with a deadly combination of drugs in her system, including propofol, the substance most commonly known for killing Michael Jackson.
