In 1976, rancher Manuel Gomez of Dulce, New Mexico — a small town on the Jicarilla Apache Indian Reservation — became one of the most prominent figures in the cattle mutilation saga when he reported losing multiple cattle to unexplained mutilations. Gomez's animals were found with the same characteristic injuries documented across the American West: surgical removal of soft tissue, absence of blood, and no tracks or signs of predators. The Dulce cases attracted the attention of state police officer Gabriel Valdez, who investigated mutilation reports in northern New Mexico for years and became convinced the mutilations were the work of a covert government operation, possibly related to monitoring radiation or biological contamination in livestock near nuclear testing sites. The Dulce area subsequently became associated with broader conspiracy theories, including the alleged existence of an underground military base beneath Archuleta Mesa. While the underground base claims lack credible evidence, the cattle mutilations in the Dulce area were well-documented by law enforcement and remain among the most investigated cases in the phenomenon's history.
