Season 1

Gosk and Roberts will each host four episodes, in which they'll focus on the reasons why a particular killing occurred and explore how investigators uncovered the motive in order to crack the case. From a staged suicide to a family massacre, Gosk and Roberts strive to understand each crime's motive and to shed light on what drove the killers. They conduct on-the-ground inquiries, returning to the crime scenes and sitting down with victims' friends and family, law enforcement, attorneys, psychologists, and even the killers themselves-- to uncover the story of how justice was sought and ultimately attained. At the core of their investigative reporting is the pursuit of a deeper understanding of the relationships behind the horrific killings and of the psychology of the people who committed them.
