One of the most violent crimes in U.S. history took place in the quiet, neighborly town of Villisca, Iowa. A family of eight went to church that night, went back home, got into their beds, and fell asleep. When the sun rose the next morning, none of them would be alive. Their house was a scene of unimaginable violence and bloodshed. The entire family of eight was bludgeoned beyond recognition with an ax while they slept. Six of them were children. Was it a madman who just picked their house at random... or was it much more than that? Special Agent Roy Marshall guides us through the crime scene, the investigation, the clues, and the fallout that led right to the steps of the State Capital.
