Cristian Sarmiento Vega, a 30-year-old Hispanic man, went missing on or around July 27, 2011, while attempting to cross the U.S.-Mexico border near Nogales, Arizona. He was described as 5 feet 2 inches to 5 feet 4 inches tall, 130 to 140 pounds, with very short black hair, brown eyes and a tattoo of two faces — one smiling and one sad — on an arm. He was last seen wearing a gray shirt, black pants and size 8 shoes, and believed to have had a small black wallet with his voter ID card.

A family member traveling with Cristian was apprehended by U.S. Border Patrol and later reported that an unknown individual violently struck Cristian, leaving him injured and unable to continue; the family member says Cristian was left in the desert near a place called La Brecha or the Gap. The Pima County Medical Examiner’s Office opened a report on August 28, 2012. There have been no significant updates on his whereabouts since the family member’s account.

Does anyone have information about Cristian’s movements near Nogales in late July 2011 or about La Brecha that could help shed light on what happened?
