When a young, pregnant Massachusetts woman is found dead in 2021, local police write off her death as a suicide. However, the findings of a medical examiner hired by the victim’s family prompt the FBI to step in and perform an expert investigation of their own. Federal authorities charge a disgraced police officer with the premeditated murder of a young woman they say he had abused for years in this episode of Last Seen Alive.
Sandra Birchmore was 23-years-old when she was murdered while 8-10 weeks pregnant with her first child in 2021. Sandra’s lifelong dream had been to become a police officer.
