Antonio Ramirez Lopez was 18 when he was last seen crossing the U.S.-Mexico border at Lukeville, Pima County, Arizona, on August 25, 2011. He was described as a Hispanic male, about 5 feet 10 inches to 5 feet 11 inches tall, weighing 180 to 185 pounds, with brown hair and brown eyes and a scar on his lower back.

On the day he disappeared he wore a black cotton t-shirt with white marks, black jeans (32-inch waist, 30-inch inseam), a black fake leather belt and black tennis shoes with white accents, size 8. He was carrying a childhood photograph of himself. The Pima County Medical Examiner’s Office is the primary agency handling the investigation, which remains open.

Few additional facts are known publicly and the case lacks a confirmed outcome. If anyone has information about Antonio’s crossing through Lukeville on or after August 25, 2011, or remembers seeing him, please come forward.
