Salome Zequeida Castillo, a 38-year-old husband and father, was last heard from in a phone call to his wife on May 30, 2011. He told her he and a traveling companion planned to cross the border the next day. He was last seen in the vicinity of Altar, Arizona, during a trek through the desert.

Castillo is described as a Hispanic male with black, curly hair, a beard, and brown eyes, standing between 5 feet 4 inches and 5 feet 10 inches and weighing 200 to 220 pounds, with a dark patch on one ankle. He was reportedly wearing a red XL t-shirt, a black XL t-shirt, light blue Guess jeans and white Reebok or Nike tennis shoes, and carrying a brown and pink backpack containing a religious scapular and a photo of himself with his daughter. His traveling companion later said Castillo’s feet became too injured to continue after three days of walking and that he was left near a wash.

The Pima County Office of the Medical Examiner opened a case but no precise location was provided for searching the vast desert. If anyone had contact with Salome around late May or early June 2011 or knows of possible remains left near washes around Altar, please share what is known.
