Armando Mendoza Guerrero was 34 when he disappeared in June 2012 after crossing into the United States from Mexico, likely near Sasabe, Arizona. He was traveling on foot with a small group that included three men from his hometown and was moving through rough desert terrain between Sasabe and Arivaca. The group believed they were being pursued by Border Patrol; in the panic they scattered and Armando was last seen by his companions as they ran in different directions.

At the time he went missing he was described as wearing military-style clothing, likely camouflage, and carrying a camouflage backpack that contained his license, voter ID card, and cell phone. Distinguishing marks include a tattoo of a heart with the letter G on his right arm, a scar on the lower part of one leg, and a large mole on an upper arm. The Pima County Medical Examiner’s Office is listed as the investigating agency. Few details are known beyond the companions’ accounts of that chaotic moment in the desert.

If anyone was in the Sasabe–Arivaca area in June 2012 or knew Armando or the men he was traveling with, any information could help explain what happened to him.
