(L to R) Ingrid Loana Baca, Karla Lechuga, and Alejandra Romero, members of the Lirios Buscadores Izcalli collective, check messages in a "Peace Mailbox" installed at a church in Tepoztlan, state of Morelos, Mexico, on August 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.
