Crecencio Flores Lugo, a 37-year-old Hispanic man, was last seen near Sasabe, Arizona, on February 25, 2006. Reports give his height as between 5 feet 11 inches and 6 feet 1 inch, and his weight between 153 and 173 pounds. No communication, witnesses, or signs of struggle are reported from that day.

The disappearance was not officially filed until July 10, 2009, when the Pima County Office of the Medical Examiner took the case. It was later entered into NamUs on July 30, 2012 as MP15877. The delay in filing and the border-area location are noted concerns; crossing into Mexico, voluntarily or under duress, has not been ruled out.

Few concrete leads are recorded and the trail described in reports is sparse. If anyone knew Crecencio, saw him around Sasabe on or after February 25, 2006, or has information that could help, please come forward.
