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.''
Sgt. Joe Kenda faces his worst nightmare when he learns that a friend and fellow officer, Mark Dabling, has been killed in the line of duty; police conduct an all-out manhunt and discover the gunman is even more dangerous than they'd thought.
The discovery of a 13-year-old boy killed in an explosion shocks police and their grief turns to alarm when they discover a second, unexploded bomb; to catch the killer, Detective Joe Kenda must first figure out the bomb's intended target.
