Sergio Armando Lopez Rosales was 18 when he was last seen on June 6, 2011, near Lukeville, Arizona, while reportedly attempting to cross the U.S.-Mexico border through the Sonoran Desert. He has not been seen or heard from since that day and his whereabouts remain unknown.

Sergio is described as a Hispanic male with black hair and black eyes, about 5 feet 6 inches to 5 feet 7 inches tall and weighing roughly 150 to 160 pounds. Distinguishing marks include a scar on his left arm, a mole on his throat, a mole on his left hand, pierced ears, and a prior fracture to his right ankle. He was carrying a photograph of himself with his girlfriend.

The Pima County Office of the Medical Examiner lists the case under the migrant category; details are sparse and the disappearance remains unresolved. If anyone has information about Sergio’s movements around Lukeville on or around June 6, 2011, please come forward.
