Almost exactly a year before John O’Keefe is found in the snow outside of Boston detective Brian Albert’s home, Sandra Birchmore is found dead in her apartment in the middle of a blizzard. In her phone are thousands of messages between her and a police detective that indicate he is the father of her unborn child. But of course, it’s never that simple. For one, he’s married and his wife is about to give birth to their third child. And two, he legally, shouldn’t be in a relationship with Sandra. Nobody was supposed to find out that he had been grooming and assaulting her since she was 15 years old, a grade school cadet apart of his police explorer’s program. Now that she’s dead - everything’s about to come out into the open right? Not exactly. When Canton PD and Massachusetts State Police investigate Sandra’s suspicious death, they rule her manner of death as a self exit. It would take the FBI 4 years to get involved and make an arrest.
