Werner Ronaldo Fajardo-Ardon, a 28-year-old Hispanic man, was last in contact with his family on July 26, 2021. At that time he was near Lukeville, Arizona, preparing to cross from Sonoyta, Mexico, toward Gila Bend, Arizona, with a group that planned an eight-day trek. He is 69 inches tall, about 165 pounds, with brown hair and black eyes.

Family members say others in the traveling group later told them Werner became ill during the journey and was left behind somewhere in the desert between the border and Gila Bend. No one has seen or heard from him since those reports. The Maricopa County Sheriff’s Office is investigating his disappearance.

What information can help narrow where Werner was last seen or who was in the traveling group?
