It is well-known by now that the show, American Horror Story, uses true crime stories in each of their seasons either directly (with their own respective twists) or as inspiration. Everyone from the Black Dahlia to John Wayne Gacy to the Zodiac killer have shown up in one way or another. There have also been a few on each season that went unnoticed or overlooked. Whether it be Richard Speck or those behind the Wineville Chicken Coop Murders every season of the series has had at least one real life horror story shown.
