Maria Celia Caguana Chungata, 34, was last seen August 18, 2008, north of Altar, Sonora, a known staging area for crossings into Arizona. She was trying to cross the border when contact was lost and she never reached her destination.

Descriptions list her as a Hispanic female, 5 feet 7 inches to 5 feet 9 inches, 170 to 200 pounds, with long thick black hair and brown eyes. When last seen she wore a blue shirt, a black t-shirt, blue jeans and either black Reebok or Nike shoes. She carried a black backpack with two cans of beans, a soda and a sports drink, and had important papers wrapped in plastic and secured in her belt. The Pima County Medical Examiner’s Office is the investigating agency.

Details about what happened after she entered the desert are unknown. Does anyone have information about Maria’s route, companions, or movements on or around August 18, 2008?
