Carlos Arizmendi Delgado was 24 when he was last seen on May 10, 2011, in Nogales, Arizona. The last known movement recorded for him was that he was in the process of crossing the U.S.-Mexico border. His case was entered into NamUs on July 30, 2012, and the Pima County Medical Examiner’s Office is listed as the investigating agency.

Carlos is described as a Hispanic male with brown hair and brown eyes, about 5 feet 3 inches to 5 feet 4 inches tall. His weight is variously estimated between 100 and 300 pounds. Distinctive tattoos include a sacred heart on his left arm, the Virgen de Guadalupe on his right arm, and a rosary around his neck; he also had a small two-centimeter scar on his neck. What he was wearing the day he disappeared is unknown.

The circumstances remain unresolved and the public information is sparse. If anyone knew Carlos, saw him in Nogales around May 10, 2011, or has information about his movements crossing the border, please share what is known.
