Hundreds of homicide cases in any given year can shake even the staunchest cities and police departments to the core. The statistics, however, don't paint the real stories and the effect that lingers -- through the pain endured by victims' loved ones, the community impact, and the memories that detectives will never forget. "Homicide City" explores unforgettable murder cases from major American cities, investigations that had law enforcement banding together across metropolitan landscapes in a sequence of manhunts. Each story is told by veteran homicide detectives, local reporters, and the victims' families.

Not every murder scene leaves behind clues in the form of bloody footprints, clothing fibers or fingerprint stains. Investigators earn their reputations by discovering evidence other than what is easy to see. This series spotlights devoted investigators who "go beyond the headlines," incorporating cutting-edge science to find the tiniest trace evidence and understand its relevance. The forensics-driven stories are told via stylized re-enactments, showing how the best investigators work to decipher which clues mean nothing and which ones will put a killer behind bars, all to bring justice to victims' loved ones.

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.

The holiday season between Thanksgiving and New Year's is often thought of as a celebratory period to spend time with friends and family. That is not always the case, though, as the period is not immune from experiencing the same types of violent crimes that occur throughout the year. This series documents stories of tragedy that struck during the holidays, with firsthand accounts from people who had friends or family members killed during the joyous time. Sometimes the victim is killed by someone close to them, such as a case of sibling rivalry turned deadly, but sometimes the killing is done by a stranger who interrupts a holiday gathering with gunfire.

Kennedy Jr., as well as conversations with Martha's loved ones.
