Mateo Manuel Gonzalez, 22, disappeared from Sasabe, Arizona on July 11, 2005. He was last seen wearing blue jeans, a t-shirt and a buttoned shirt, described at the time as between 5 feet 5 inches and 5 feet 7 inches tall and weighing between 140 and 160 pounds. He may also be known as Carlos Vasquez Tomez.

The Pima County Medical Examiner’s Office handled the investigation. There have been unconfirmed suggestions that Mateo might be alive and working in Nogales, but that possibility has not been verified.

If anyone knew Mateo, knew him as Carlos Vasquez Tomez, or has information about his movements around July 2005, please share what is known.
