Luis Alberto Lira Chagala, 30, disappeared after crossing the U.S.-Mexico border on June 22, 2009, near Sasabe in Pima County, Arizona. He was traveling with a group that included his brother; they walked west of Sasabe through remote desert terrain and were later picked up by a vehicle. After about 40 minutes on a dirt road the group reached a small intersection where distant town lights were visible and U.S. Border Patrol agents arrived.

The arrival of Border Patrol caused the group to scatter. Luis’s brother was captured north of San Pedro near State Route 86, but Luis ran into the desert and was never seen again. He is described as Hispanic, black hair, black eyes, 5 feet 1 inch to 5 feet 3 inches, 115 to 130 pounds, with an ankle scar and a white spot on his chest. He was reportedly wearing a black sweatshirt, black pants, and white shoes with navy blue stripes, possibly with a red plaid polo; he had an ID, wallet, and a Virgen del Carmen scapular.

No record of his apprehension or any confirmed sightings has been found. Did anyone in the borderland communities or travelers in that area around June 22, 2009, see Luis or know what happened after the group scattered?
