Lt. Joe Kenda recounts unsolved cases, his timeless dedication to working on them; and reflects on imparting wisdom to a rookie about how all victims and all leads matter.

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."

Actual murder cases from the 1950s and '60s get sleek, cinematic treatment in this series, transporting viewers back to a pre-forensics era when sometimes it was more about how suspects looked than what they did that determined guilt. Narrative by a fictional bystander -- who "knew" the victim -- drives the hourlong episodes, while reporters who covered the case explain how the events impacted society. Artfully crafted re-creations play out like period thrillers, staying true to fashions and styles, while spotlighting cultural taboos and social norms surrounding each case.

Victims' rights activist John Walsh returns to weekly TV as host of a documentary-style investigation series. Walsh details stories of ongoing cases involving fugitives, with the intent of expanding searches outside the United States. Interviews with victims, loved ones and law enforcement accompany new leads in each hourlong episode, giving the public information to facilitate the capture of suspects. Walsh, a spokesman for the National Center for Missing & Exploited Children, hosted the series "America's Most Wanted" for 25 years, helping apprehend more than 1,200 criminals.

Veteran journalist Paula Zahn steps out of the studio and into the field to unravel criminal investigations, tracking the drama of each story by featuring the opinions of those closest to the case, including law enforcement officials, the families of the victims and the incarcerated, lawyers from both sides, and first-time TV interviews with convicted murderers.

There's a reason murder investigations don't begin with preconceived notions. Sometimes those least expected to be capable of committing such dark deeds -- respected role models and trusted members of the community -- can have a sinister side. "Unusual Suspects" documents baffling, challenging investigations, actual cases that were anything but cut and dry. Episodes feature in-depth interviews with leading law enforcement personnel combined with stylized re-enactments, illustrating how illusive offenders evaded capture for years before being undone by persistent police work.
