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.

Retired NYPD Detective Kevin Gannon questions if the country's most notorious string of mysterious, accidental drownings are accidents or homicides and wonders if they could all be connected to The Smiley Face Killers.

Each episode of this true-crime reality series examines a different felon, usually a female, who has committed murder or attempted murder. The victim is usually the perpetrator's partner. The documentary-style series features interviews with friends and family members of the accused and victims, law-enforcement officials, attorneys and other people with first-hand knowledge of the cases.

A groundbreaking six-part documentary directed and produced by Andrew Jarecki and produced and shot by Marc Smerling (the Oscar nominees behind "Capturing the Friedmans") delves into the strange history of real estate heir Robert Durst, long suspected in the still-unsolved 1982 disappearance of his wife as well as the subsequent murders of family friend Susan Berman and neighbor Morris Black. It features an extended, revealing interview with Durst himself, with whom Jarecki developed a unique relationship following the release of "All Good Things," Jarecki's 2010 feature about Durst's life starring Ryan Gosling and Kirsten Dunst. "The Jinx" results from nearly a decade of research by the filmmakers, who expose police files, key witnesses, never-before-seen footage, private prison recordings, and thousands of pages of formerly hidden documents.

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.

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.

From the outside, families seem like harmonious units in loving homes. But you don't necessarily know what secrets families are hiding from the outside world. This series, narrated by actress Brenda Strong, explores families hiding the most extreme of family secrets: murder. Each episode explores a death in a family, unraveling the motives of the family members, all of whom are potential suspects -- and potential victims. Sibling rivalries, disputes over family businesses and infidelity are some of the factors that lead to the families' ultimate betrayals.
