American Nightmares

American Nightmares

Every headline hides a deeper story. American Nightmares pulls you into the most unsettling true crime cases—one season, one case at a time. These are the crimes that kept detectives awake, shattered families, and left entire communities on edge.Told through raw interviews, gripping investigative detail, and cinematic storytelling, each season reveals how these nightmares unfolded—and the long road to uncovering the truth. You may think you know the story. You don’t. Season 3 - Unknown Subject For nearly a decade, he crept in the shadows, attacking women in the middle of the night — and then vanished. The 1998 murder of a brilliant scientist near Georgetown University marked a terrifying escalation. Investigators had DNA linking him to multiple crimes, but for years, he had no name — only the label “Unknown Subject.” This season uncovers the chilling case of the Potomac River Rapist, and the patrol cop who finally cracked it. Season 2 - Murder in a Safe Place In a quiet hospital just outside Washington, D.C., a 50-year-old nurse named Sherry Crandell was raped and murdered inside her workplace — a place that was supposed to be safe. With DNA, fingerprints, and even a witness to the crime, police had evidence — but no suspect. This season revisits the cold case that continues to baffle investigators and devastate a family, more than two decades later. Season 1 - 2 Hours: An American Nightmare One of the most shocking crimes in modern American history: a prominent couple, their 10-year-old son, and their housekeeper taken hostage and brutally murdered in their Washington, D.C. home. Over the course of 22 horrifying hours, they endured torture and terror before their killers tried to burn the evidence. This award-winning debut season revisits the infamous Mansion Murders, exposing new details and the twisted logic behind a senseless act of violence.
