Calistro Villareal was of a breed of desperados that would be found any day of the week frequenting the many bars in Ajo, Arizona during the years around 1913. In the early morning hours of January 21, 1913, Mr. Villareal, reportedly drinking heavily, gambling, and generally acting rowdy with a group of cronies in the tent of Lorenzo Villa, began to create a disturbance. At 2:00 in the morning, Deputy Meeks was awakened from sleep and called from his bed to quell the disturbance created by this group. After being told that Calistro Villareal was involved in the disturbance, Deputy Meeks began searching the town for him. While questioning a person in the area regarding the incident, Deputy Meeks was fired upon by Mr. Villareal, who had been hiding in the bushes nearby. Two shots rang out. One of those shots struck Deputy Meeks in the face, the bullet passed through his head, and he died a short time later. Calistro Villareal fled from the scene on foot and headed south in the direction of Mexico. Sheriff John Nelson led a posse into Mexico, returning empty handed when the Mexican authorities refused assistance in the search. No record exists to show if Calistro Villareal was ever brought to justice.
