Serial Killer Henry Lee Moore

Henry Lee Moore, between 1911 and 1912, was a traveling serial killer who murdered more that twenty-three people--entire families. But little is known about him--he is a mere footnote. In September 1911, using an axe, Moore killed six victims in Colorado Springs--a man, two women, and four children. In October [of that year] he killed three people in Monmouth, Illinois, and then slaughtered a family of five in Ellsworth, Kansas, the same month. In June 2012, he killed a couple in Paola, Kansas, and several days later he killed seven people, including four children, in Villisca, Iowa. Moore then returned home to Columbia, Missouri, where he murdered his mother and grandmother. At this point he was arrested and prosecuted in December 1912. [He was later hanged.]
