Francisco Sanudo Casteneda, 32, was last seen July 12, 2011, in the Ajo area of Pima County while crossing into Arizona from Mexico and was reportedly left behind in the desert. He is described as Hispanic/Latino and White/Caucasian, about 5 feet 8 inches to 5 feet 9 inches tall, around 160 pounds, with black hair and brown eyes. At last sighting he wore blue jeans, a navy blue shirt and gray shoes.

Family notes white spots on both feet and a tattoo of three dots in the webbing of his right hand between the thumb and forefinger. DNA samples from his son and daughter have been submitted to national databases. The Maricopa County Sheriff’s Office lists the investigation as open. Very little else is publicly known about what happened after he was left in the desert.

If anyone saw Francisco in the Ajo area around July 12, 2011, or has information about his crossing that day, please share what you know.
