Most true-crime shows let viewers know the identity of the victim right away, before working their way into revealing the identity of the perpetrator. That's not how things work on "Killision Course," which conceals all of the participants' roles until the episode's final act. While working toward the conclusion, each hourlong episode re-creates a murder case involving a victim, accomplice and killer. Stories often involve friends or lovers who commit crimes against people who once trusted them. It's all part of the road leading up to the big reveal, which is when viewers learn what role each party played in the fatal act.

Marriage is supposed to be a happy time in a couple's life. With engagements, weddings, and picturesque honeymoons -- hope and happiness were in abundance until a tragic and very mysterious death occurs to cut short these joyous celebrations. Viewers learn when the red flags first began -- was it because of depression or manipulation and did it overshadow a wonderful time? Is it because of prophetic dreams and the killer was fulfilling a divine mandate, or is there something lurking beneath the surface that no one knew about.

Some of the world's most notorious murders are the subject of "It Takes a Killer," which investigates the crimes from the perspective of the killers, trying to get inside their minds and determine their motives. Leading homicide investigators and experts from such agencies as the FBI and Scotland Yard take a look at the evidence pulled from crime scenes and profile the killer's behavior to try to piece together the details of each murder, explaining when, why and how each criminal committed the crime. For the wannabe detectives watching the show, the experts also reveal how the crime was solved -- which often requires authorities to think like a killer.

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.

What lurks in the shadows during graveyard shifts comes to light in this series, a quintessential Investigation Discovery offering that features nail-biting re-enactments of actual crimes in which darkness hides predators hungry for a midnight snack. Told through interviews with victims' family members and law enforcement, each story begins after a brutal crime is committed in the quiet of the night, and community members are left wondering who might be next. Investigators get to work, knowing that each time the sun sets, the body count might rise.

On May 30, 2005, 18-year-old Natalee Holloway disappeared on the island of Aruba. Her case resulted in a worldwide media frenzy, yet Natalee's body was never found, and her father, Dave Holloway, has never stopped searching for answers. Now, 12 years later, he's following what he believes to be the most credible lead to date: a detailed firsthand account from a man who claims to know the whereabouts of his daughter's remains, and the hope of finally getting a conviction of Joran van der Sloot. This true crime series follows Dave and T.J. Ward, the family's longtime private investigator, in the latest and perhaps final chapter of the decade-long pursuit to uncover what really happened to Natalee.
