Monica Silva Ortiz, 43, was last seen on July 21, 2009, crossing the U.S.-Mexico border near Sasabe, Arizona. Reports say she was left at a location described only as four hours north of Sasabe in remote Pima County desert. She was Hispanic, with black hair and brown eyes, and stood between 5 feet and 5 feet 3 inches. Her family noted a burn scar on the back of one hand and a mole on her left clavicle.

When she disappeared she was believed to be carrying several important documents: a Mexican passport, a birth certificate, a credential, and her mother Natalia Ortiz’s death certificate. The Pima County Medical Examiner’s Office opened a case on August 18, 2009. The lack of a precise drop-off location and few other specifics have left the circumstances unclear and the family without closure.

If anyone has information about Monica’s movements around Sasabe in July 2009 or remembers seeing her documents, please share what you know.
