The Villisca Axe Murders

The Moore family was an affluent family located in the town of Villisca, Iowa. They were well-known and well-liked in town. So when all 6 of them, along with 2 young guests, were found bludgeoned in their own home one morning in 1912, people had no idea who would have committed such a crime. Was this heinous crime committed for some financial motive, or could it have been a serial-killer going on a murder spree through the town?
