Sergio Flores Aviles, also known as Jose Flores, Alfonso Villa Palafox, and Adolfo Palafox, was last seen June 29, 2007, in the border community of Sasabe, Arizona. He was 30 at the time and described as between 5 feet 3 inches and 5 feet 5 inches tall, weighing 170 to 190 pounds. Distinctive marks include a tattoo on his left shoulder of a heart with devil horns and a tail, and a large scar on one temple.

It is believed he may have been carrying a birth certificate when he disappeared. His case is listed with the Pima County Office of the Medical Examiner under case number FSC MPR 584 and the circumstances of his disappearance are recorded as unknown. Very few concrete leads or details about his last movements have been reported.

If anyone knew Sergio, saw him in Sasabe around late June 2007, or has information that could help, please share what is known.
