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. Hourlong 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, unraveling the mystery and uncovering what broke the cases open.

Investigation Discovery and People magazine partner to re-examine some of the most high profile crime cases in recent history. The one-hour series brings viewers tales of betrayal, buried secrets and unsung heroes, ripped from the pages of one of the nation's top weekly magazines. These stories transcended news and became part of pop culture, revealing shocking twists, new evidence, and unexpected resolutions. Interlaced within every episode are exclusive interviews with People's journalists, archival footage, re-creations, and firsthand accounts by those closest to the investigations.

The stars of "Suspicion" walk a fine line between certainty and skepticism when confronted with mysterious situations. Instead of trusting others, the subjects lean on their instincts and ultimately take matters into their own hands. Featuring emotional first-person interviews detailing endless twists and turns that come with following dangerous hunches, the series tells actual stories of folks who suspect imminent danger and become fixated on finding the truth. Tales build suspense from the moment something feels amiss.

Powerfully emotional stories tell of people who have been targets of compulsive stalkers. According to the Centers for Disease Control and Prevention, more than 6 million people in the U.S. are stalked each year, and in most instances, the stalker is someone the victim already knows. The series' hourlong episodes dramatize actual cases through visceral re-enactments and pointed testimony of victims, family members and law enforcement authorities, revealing what happens when stalkers can't have what -- or who -- they want, and stop at nothing to ensure that no one else can either. The chilling accounts probe the mechanics of an obsessive mind and the devastating impact of delusion.

Chilling scenarios unfold in this true-crime series, which tells actual stories of people who shared their lives with loved ones who became killers. Each hourlong episode puts viewers in the shoes of the loved one, who first notices that something is amiss, interprets the puzzling signs and clues, and eventually comes face-to-face with the horrible truth: that the person has a very dark side. Exclusive interviews and firsthand accounts of the critical moments leading up to the vicious acts showcase devastating, often undiscussed consequences on the people who have nurtured, loved and raised a murderer.

Stylized re-enactments tell stories of actual crimes that have a similar moral: choosing to trust someone can be a life or death decision. One moment, the world seems so safe; the next, it becomes completely unrecognizable, all because someone betrays the trust of a family or social circle, leading to paranoia and suspicion and ultimately a cold-blooded murder. The husband, the best friend, the business partner, the stockbroker, the neighbor and the mistress are left looking over their shoulder, living in fear of the killer, or the truth, or being caught in a lie. As the investigation unfolds and secrets are laid bare, it produces a horrific realization: the victim was killed by someone they trusted.

Investigation Discovery digs deep into the psychological forces that drive a person to commit homicide. What compels him or her to decide that taking a life is something that must be done? Perhaps the offender has been struggling with lifelong issues. Or maybe it's an inability to cope with pressures of adulthood. Whatever the case, the perpetrator's tortuous journey stunningly ends in violence. Episodes include interviews that offer insight into the troubling relationships between offenders and victims. Law enforcement personnel and psychiatrists also provide context. And, of course, ID's typical re-creations bring to life complex backstories, the homicide scenes and the aftermaths of senseless crimes.

Raw, unbridled and chilling depictions of human desires surface in "In Ice Cold Blood." True crime is depicted at another level as Ice-T takes viewers straight into the stories.

These stories are told through re-enactments, in-depth interviews and archived footage.

Two of the top trial lawyers in the U.S. match wits as they deconstruct actual homicide cases and debate the ultimate question of innocence. In each hourlong episode, Brooklyn District Attorney's Office lead prosecutor Anna-Sigga Nicolazzi and award-winning defense attorney Darren Kavinoky present their respective sides of a famous case, putting the accused center-stage and leaving the viewer to decide: did he do it? Stories are interwoven with commentary from Nicolazzi and Kavinoky, as well as from law enforcement and friends and family of the victims.

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.
