Ernesto Uriquides-Guillen was 36 when he was last seen in 1991 near Nogales, Arizona. Records list him as Hispanic and Caucasian, about 5 feet 5 inches and 150 pounds, with black hair and black eyes. Reports indicate he crossed the border from Mexico into the United States and was not heard from again; the exact date of disappearance is not recorded.

No contemporaneous leads or details about companions, destination, or plans were recorded, and the case remained cold until a missing person report was filed with the Maricopa County Sheriff’s Office on July 18, 2017. His information, including dental records and DNA, was entered into NamUs for comparison with unidentified remains.

Anyone who knew Ernesto, saw him around Nogales in 1991, or has information about his crossing into the U.S. is asked to come forward.
