The director of the artificial intelligence "Regresa" (Returns) project, Mexican anthropologist Ana Itzel Juarez, poses during an interview with an AFP reporter in Mexico City on September 29, 2026. More than 134,000 people are registered as missing in Mexico, leaving thousands of families searching for answers about relatives who vanished years ago. Against this backdrop, researchers are developing artificial intelligence-based tools aimed at supporting search efforts and helping families process information that could provide new leads in missing persons cases.
