Manuel Guaman Mayancela was 21 when he disappeared while crossing the U.S.-Mexico border and was last seen August 1, 2011, in the Santa Rosa, Arizona area. Reports say he was part of a group but was left behind in the desert. He was described as Hispanic/Latino, about 5 feet 5 inches and 140 pounds, with black hair and black eyes, and a dog-bite scar on one ankle.

He reportedly carried a green backpack and a black cap with a white line, and wore a yellow plaid shirt, a blue shirt, and blue jeans. Papers with phone numbers were among his belongings, including Guatemalan numbers and a belt with hidden papers containing names and numbers. He may have tried to signal for help by lighting a fire.

The Pima County Medical Examiner’s Office is listed as the investigating agency. The disappearance was reported August 15, 2011, and his case was entered into NamUs on July 30, 2012. If anyone knew Manuel, saw him around Santa Rosa in early August 2011, or has information about his route or the group he was with, please come forward.
