Diego Tum Cotiy was 27 when he vanished in June 2010 while attempting to cross from Altar, Sonora into the United States. The last contact with his family was a phone call on June 9, 2010, when he said he planned to cross the following day; after that call there was no further word.

Diego is described as a Hispanic male, 5 feet 2 inches to 5 feet 4 inches tall, 140 to 160 pounds, with black hair and black eyes and a burn scar on his right foot. He was last seen wearing blue jeans, a gray short-sleeved shirt, a beige and black leather belt, black low boots, and carrying a beige backpack with his clothing. The Pima County Medical Examiner’s Office in Tucson became the investigating agency; that office often handles unidentified remains of presumed migrants found in the Arizona desert.

Diego’s family has had no confirmed news since his disappearance and the case remains unresolved. If anyone knew Diego or has information about migrant crossings from Altar into Arizona around June 2010, please come forward.
