On the night of June 9, 1912, the Moore family and two guests were brutally murdered with an axe, though it was only on the morning of June 10, 1912, that they were found in their home by a neighbor and Ross Moore, the brother of Josiah Moore.

Josiah B. Moore and Sarah Montgomery were married on December 6, 1899. They had four children: Herman, Katherine, Boyd, and Paul. Joe was a prominent and well-liked businessman. By 1912, the Moore Implement Company (a John Deere Company franchise) was a solid competitor with other Villisca and area hardware stores, including the Jones Store owned by his former employer, F.F. Jones. Sarah was active in the Presbyterian church and assisted with Children's Day exercises. On the morning of June 10, 1912, Joe (43) and Sara (39), their four children, and two visiting children (Lena and Ina Stillinger), were found bludgeoned to death with the Moores' own axe. Their unsolved murders began a chain of events that split the borough of Villisca and forever changed the course of the town's history and the lives of its inhabitants.

It is within the Villisca Community School District. Residents are zoned to Southwest Valley High School, operated by the Corning Community School District, and shared with the Villisca district as part of a grade-sharing agreement.
