Jorge Luis Picos Felix, known to family as Piquillo, was 27 when he was last seen near Lukeville, Arizona, on August 23, 2011, as he crossed the U.S.-Mexico border. He is described as a Hispanic man with brown hair and brown eyes, standing between 5 feet 4 inches and 5 feet 5 inches and weighing about 140 to 145 pounds.

On the day he vanished he carried a gray Nike backpack, wore a white button-down blue-striped Guess shirt layered with a cotton Aeropostale polo, light blue jeans, navy blue plaid boxers, cotton socks and white and gray leather Jordan tennis shoes. Personal items included a silver watch, a prayer card of the Virgin of Guadalupe and a clear rosary. Distinctive marks were a scar on his right wrist from tendon surgery, a one-inch brown mole on the right side of his lower back, pierced ears, old wounds on his right foot and right elbow, and a burn mark on the top of his right foot.

The Pima County Medical Examiner’s Office is handling the investigation. What information might help locate Jorge or explain what happened after he was last seen near Lukeville?
