Lorenzo Sanchez Salas was 43 when he went missing after an attempted border crossing north of Altar, Sonora, Mexico. He was last seen August 20, 2011, during a two-day trek; a companion reports Lorenzo became ill, vomited, and eventually could not continue. He left a backpack about 20 minutes before he was unable to walk and was reportedly left on a very inaccessible mountain while the group pressed on.

The companions were stopped by U.S. Border Patrol near Highway 86 about August 26, 2011. Lorenzo is described as Hispanic, 64 inches tall, 110–120 pounds, black medium-short hair, brown eyes, small scar near his right eyebrow, last wearing a green medium shirt, size 30 black jeans and size 27 black shoes, carrying a backpack and his voter ID card.

Does anyone have information on Lorenzo’s whereabouts or what became of him after August 20, 2011?
