In mid‑July 2026, volunteer search collectives and authorities uncovered several hidden burial sites across Mexico, including graves in San José del Cabo (Baja California Sur), Miguel Alemán (Tamaulipas), Salamanca (Guanajuato) and Jiutepec (Morelos). Forensic teams were called in to process the remains and identify victims, while groups such as "Amor por los Desaparecidos" and "Salamanca Unidos Buscando Desaparecidos" reported threats against their members. A few weeks later, in early August, the collective Colectivo Buscando a Tolano discovered additional clandestine pits in the Vista Horizonte area of southern Tijuana and in the Playas de Rosarito landfill. The sites contained fragmented bones, weapons and ammunition. Investigators linked the remains to youths who vanished in October 2025 and identified a suspected cartel operative, María de la Luz Damián Andrade ("La Tía"), who had been arrested in March 2026 on forced‑disappearance charges. National Guard and state prosecutors continued to secure the areas and collect evidence, expanding the scope of the investigation into forced disappearances and illicit burial practices across the country. ## Timeline ### 2026-08-04: Search collective uncovers clandestine burial sites in Tijuana and Rosarito Colectivo Buscando a Tolano found clandestine burial sites in Tijuana and human remains in the Rosarito landfill while searching for missing youths, linking the cases to detained cartel member “La Tía.” 2 sources. https://clstr.news/cluster/search-collective-uncovers-clandestine-burial-sites-in-tijuana-and-rosarito ### 2026-07-12: Clandestine graves uncovered in several Mexican states Clandestine graves were found in Baja California Sur, Tamaulipas, Guanajuato and Morelos, prompting forensic investigations and protection requests for search activists. 8 sources. https://clstr.news/cluster/seven-clandestine-graves-uncovered-in-miguel-alemn-tamaulipas --- Cite as: Mexico clandestine graves discoveries.
