The True Stories Behind 21 American Horror Story Characters

One of the story lines from the first season revolves around a couple of nurses who are killed in the Murder House. Though the nurses on the show (played by guest stars Rosa Salazar and Celia Finkelstein) aren't based on individuals, Ryan Murphy has said their murders are inspired by the Richard Speck massacre in 1966. Speck, a seaman from Texas, broke into a Chicago dorm filled with nurses and viciously tortured, raped, and killed eight of them in one night. The sequence in the show is light compared to what actually happened.
