July 6th, 2003, was supposed to be a routine Sunday for Joanie Harper. She, along with her three young children, and her mother, attended church that morning, only for that to be the last time the Bakersfield, California community saw them alive. As the five returned home, they were shot and killed in what appeared to be a break-in. However, the truth behind the crime scene was far more sinister.

Retired FBI Supervisory Special Agent Mark Safarik discusses how elementary school vice principal Vincent Brothers slaughtered his family and breaks down the unique staging of the crime. Later, he provides insight into the behavioral dynamics of the shocking case.

Mark Safarik now serves as the President of Forensic Behavioral Services International, a company that provides expert consultations and services to clients, including criminal and civil litigation, lectures, and training. After his 23 years with the FBI, Mark's unparalleled expertise has been used by various television shows, attorneys, investigators, and law enforcement agencies worldwide.
