Premise: Lt. Joe Kenda spent 23 years in the Colorado Springs Police Department, where he amassed a lifetime of memories catching killers and helping solve close to 400 homicide investigations. The vivid memories are brought back to life in this hourlong series, as Kenda reopens his ``Murder Books'' for viewers -- folders in which every detail of his murder cases is held -- to revisit the most disturbing cases still haunting him today. As he details the process of how he solved the crimes, Kendra also embarks on a personal journey, coming to terms with long-suppressed nightmares. As he says, ``I don't want to tell these stories. I need to.''
