A search team made up of local police, military personnel, council officials, and family members, meet up before setting out to look for Brenda Aguilar Guadalupe in Tepotzotlan, Mexico State on March 13, 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.
