Season 4 - 22 Hours: A Second Look

Host Megan Cloherty returns for a new season of American Nightmares. In the upcoming season, we revisit the story that launched the series: a D.C. power couple, their 10-year-old son, and their housekeeper—held hostage for nearly 24 hours before being murdered inside their own home.

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.
