Horacio Hernandez Sol was 54 when he was last seen near Altar, Sonora, Mexico, on August 31, 2009, intending to cross into Arizona. He is described as a Hispanic male with black hair and brown eyes, between 5 feet 2 inches and 5 feet 4 inches tall, and weighing 170 to 178 pounds. At the time he was reportedly carrying a backpack and wearing a navy blue short-sleeve shirt, light blue denim pants, and burgundy dress shoes.

The Pima County Office of the Medical Examiner opened a case on October 19, 2011, and a Mexican consulate liaison was involved as agencies on both sides of the border worked the investigation.

If anyone saw Horacio around Altar or remembers someone matching his description heading toward Arizona in late August 2009, please share what you know.
