Juan Carlos Ferrer Salmeron, a 30-year-old Hispanic male, was last heard from on April 17, 2008, when he called from Caborca in Sonora to say he was heading to Arizona. He was last seen in the Sasabe, Arizona, area in Pima County. His case was reported to the Pima County Office of the Medical Examiner on May 7, 2010.

At the time he disappeared he was described as 5 feet 8 inches to 5 feet 10 inches tall and weighing 232 to 252 pounds, with a scar on the left side of his forehead and warts on his ear. Hair and eye color are listed as unknown. He was reportedly wearing a white and blue jacket with black lining, blue tennis shoes splattered with white paint, and carrying a small backpack with T-shirts. Those items are the last known belongings tied to him.

Very little is known about why he was traveling or what happened after that final call. If anyone saw Juan in the Sasabe area around April 17, 2008, or has information about his route into Arizona, please come forward.
