From the moment a homicide is reported, a file is assembled to document every facet of the investigation - crime scene photos, notes and observations, forensic reports, witness interviews, suspect profiles - and continues to grow with new information until an arrest is made and conviction attained. Investigation Discovery opens these "murder books" to tell haunting tales buried within the pages. Hour-long episodes take viewers back in time with details of decades-old cold cases using actual archival footage, crime-scene evidence and first-person interviews with lead investigators, unravelling the mystery and uncovering what broke the cases open.
