Summary based on the NamUs case record (MP16757) and 1 other source
In the spring of 2011, a young man named Carlos Arizmendi Delgado, just 24 years old, vanished under circumstances that remain shrouded in uncertainty. He was last seen on May 10, 2011, in Nogales, a city in Santa Cruz County, Arizona, that sits on the border with Mexico. The last known information about his whereabouts is that he was in the process of crossing the U.S.-Mexico border. At the time of his disappearance, Carlos was described as a Hispanic male with brown hair and brown eyes, standing between 5 feet 3 inches and 5 feet 4 inches tall. His weight was estimated to be between 100 and 300 pounds.

Distinctive tattoos marked Carlos's body, silent storytellers of his identity. On his left arm, he wore a tattoo of the sacred heart, and on his right arm, an image of the Virgen de Guadalupe. A rosary was tattooed around his neck, and a small two-centimeter scar was also present on his neck. What clothing he was wearing on the day he disappeared is unknown, another missing piece in the puzzle of his last known moments. The Pima County Medical Examiner's Office is the primary agency investigating his case, which was officially created in the National Missing and Unidentified Persons System on July 30, 2012.

The case of Carlos Arizmendi Delgado is a quiet one, with little public information available beyond the initial details of his disappearance. He is one of many individuals who have gone missing along the border, a region where the vast and often harsh landscape can swallow stories whole. The circumstances of his disappearance, simply noted as 'last seen crossing the U.S.-Mexico border,' offer a stark and open-ended final chapter to his known movements. For his family and those who knew him, the passage of time has not brought answers, only the enduring pain of not knowing what became of him after he was last seen on that May day. His case serves as a somber reminder of the ambiguous and often unresolved disappearances that occur in this border region.
