The Ruby Murders is the popular name for three separate incidents involving the deaths of six American citizens at or near the town of Ruby, Arizona. The first incident occurred in February 1920 when Mexican bandits, thought to be Villistas, robbed and killed the two owners of the Ruby Mercantile. A second attack happened fourteen months later in April 1921 when again Mexican bandits killed the store's owners and robbed the place. Two of the bandits were arrested for the crime, but they briefly escaped custody in July 1922, after killing another two men, which led to the largest manhunt in the history of the Southwest.
