Alfonso Meza Caldaza was 30 when he disappeared in early summer 2004. He was last seen June 1, 2004, in Nogales, Arizona, reportedly attempting to cross the border into the United States. Described as Hispanic and White/Caucasian, he was between 5 feet 8 inches and 5 feet 10 inches tall, weighed 180 to 200 pounds, and had brown hair and brown eyes. A scar on the pinky finger of his left hand is a distinguishing feature.

Details about who, if anyone, accompanied him, his intended destination, or the precise circumstances of the crossing are not available. The Maricopa County Sheriff’s Office is handling the case and it remains open. If anyone knew Alfonso, saw him in Nogales around June 1, 2004, or has information about his movements that day, please share what is known.
