Summary based on the NamUs case record (MP16596) and 2 other sources
In the heat of the Arizona summer, on July 17, 2010, a 30-year-old man named Edgar Agustin Avechuco Calderon was last seen near Lukeville, a small community on the U.S.-Mexico border. Edgar, also known by the nickname 'Chapo,' was a Hispanic man with brown hair and dark brown eyes. He was relatively slight in build, standing between 4 feet 10 inches and 5 feet tall and weighing between 100 and 110 pounds. Distinctive tattoos adorned his arms, with 'Agustin' on one and 'Kavin' on the other. When he was last seen, he was wearing a Raiders hat, a brown, white, and black striped short-sleeved shirt over a white sleeveless shirt, black jeans, and white and sky blue tennis shoes, possibly made by Nike.

Edgar's journey began in Sonoyta, Mexico, on the evening of July 17th, when he set out with a group to cross the border. The trek through the desert is arduous and unforgiving, and according to those who were with him, Edgar began to struggle. Three days into their journey, on July 20th, the group reported that Edgar could no longer continue walking. They stated that he had run out of water and was exhausted, but that he was not injured. Tragically, he was left behind in the vast and desolate landscape of the Arizona desert.

The Pima County Medical Examiner's Office is the primary agency investigating his disappearance. His case was officially created in the National Missing and Unidentified Persons System on July 30, 2012. Despite the passage of time, Edgar's case remains an open and unresolved missing person investigation. The circumstances of his disappearance, as recounted by his traveling companions, paint a grim picture of a man overcome by the harsh realities of a desert crossing. Without any further information or sightings, the exact details of what happened to Edgar Avechuco Calderon after he was left behind remain unknown, a sorrowful mystery held by the silent desert.
