Pedro Ornelas, a male Mexican sanitation worker in his early forties employed at the Phelps Dodge copper mining camp in Morenci, Arizona, lived with his wife Mercedes Chávez in company housing identified as AC 264 House, part of the sprawling copper camp community. Contemporary accounts and later research describe him as one of the uncles of Paula Medina, a young woman who had become the unwanted focus of attention from a miner named Refugio Macías.
For several years, Macías had tried to force his romantic attentions on Paula despite her lack of interest, and the family—particularly her uncles—had warned him to stay away. In the days leading up to the killing, his behavior escalated: on January 17–18, 1929, he was reported to have tried to push his way into the nearby home of Cepriana Delgado while armed with a pistol, and he shot and wounded another man, Antonio Lerma, during the same period of disturbances in Morenci.
In the early morning hours of January 18, 1929, Macías returned to the Delgado house around 1:00 a.m., again causing a noisy disturbance and attempting to force entry. Inside the residence were Paula Medina and her two uncles, Ornelas and fellow uncle Julián De Luna, who shared the household and were part of the same Mexican mining-camp community. Awakened by the commotion, Ornelas and De Luna dressed and went up to the front porch to confront the intruder and see who was trying to get into the house. There, on the porch, they came face to face with Macías, who was armed with a. 32-caliber Colt revolver. According to Ornelas’s death certificate summary and later historical reconstructions, Macías fired on the two men with what the coroner described as “murderous intent,” mortally wounding them both. Ornelas was hit and died almost instantly, falling from the porch to the ground outside, while De Luna managed to stagger back into the house before he collapsed and died inside.
After the shootings, Macías left the scene and started along the road between Morenci and the nearby town of Clifton. Accounts based on prison and newspaper records indicate that Greenlee County authorities moved quickly: around an hour to a few hours after the attack, deputies intercepted him on the road in the dark, still carrying the same pistol used to kill Ornelas and De Luna. At the time of his arrest he admitted to having shot the two men, though he claimed that he had done so only after they allegedly attacked him with knives—an account that the state later argued was a self-serving attempt to recast the confrontation as self-defense. Investigators and prosecutors instead highlighted the events of the previous day, his earlier armed intrusions and shooting of Antonio Lerma, and evidence that he had quietly packed a suitcase and left it with a friend to be forwarded later, suggesting he anticipated fleeing the area after the violence.
The case against Macías moved quickly through the courts in Greenlee County. Witness testimony about his harassment of Paula Medina, the warnings he had been given by her family, his armed behavior earlier on January 17–18, and the deadly porch confrontation helped the prosecution frame the killings as deliberate and premeditated rather than a spontaneous brawl. A jury convicted him of first-degree murder for the deaths of Pedro Ornelas and Julián De Luna, and the trial court imposed a death sentence. When the case reached the Arizona Supreme Court as *Macias v. State*, the conviction and sentence were upheld, reinforcing the view that the shootings were willful and carefully considered acts, not heat-of-the-moment self-defense.
With appeals exhausted, Macías was transferred to the state prison at Florence to await execution. Contemporary prison and newspaper accounts describe him as a Mexican miner, and one California paper later remarked that the state ultimately hanged him “for the murder of two of his countrymen, Pedro Ornelas and Julian De Luna, during a quarrel over a girl at Morenci, Ariz., on Jan. 18, 1929,” underlining both the shared national origin of killer and victims and the romantic dispute at the heart of the case. On March 7, 1930, roughly a year after the killings, Macías was executed by hanging at the Arizona State Prison in Florence, bringing the legal aftermath of the slaying of Ornelas to a formal close, though the loss of the laborer and family man remained a lasting trauma in Morenci’s Mexican mining community.
