Mexico Orders Security Crackdown At Tourist Sites After Teotihuacan Mass Shooting
Mexican authorities ordered a security crackdown at major tourist sites after a gunman opened fire at Teotihuacan's pyramids, killing one and wounding at least 13.
The attacker fired from the Pyramid of the Moon at the Teotihuacan archaeological site near Mexico City while tourists tried to descend, officials said. Authorities say one Canadian tourist was killed and at least 13 others were injured, including six Americans, three Colombians, one Russian, two Brazilians and one Dutch national. Injured victims range in age from about 6 to 61, and Mexico's National Institute of Anthropology and History closed the site until further notice.
Officials identified the shooter as 27-year-old Julio Cesar Jasso, a Mexican national who died from an apparent self-inflicted gunshot. Investigators recovered a gun, a knife, ammunition and a plastic bag reportedly holding 52 .38-caliber rounds from his belongings. They also found books, handwritten notes and an AI-modified photo linking him to the 1999 Columbine attack, and authorities say he conducted reconnaissance visits beforehand. Video from hostages shows him ranting about the pyramid's sacrificial history and threatening to "sacrifice" victims, and some reports say he invoked Hitler and anti-foreigner themes.
Early reports called the shooting isolated; later coverage, led by NPR and Fox News, highlighted security lapses and connected the crackdown to concerns about tourist safety before the World Cup. President Claudia Sheinbaum and Security Secretary Omar García Harfuch ordered immediate bolstering of security at archaeological sites and major tourist destinations, citing gaps in routine entry screening at Teotihuacan. Measures include more National Guard patrols, stepped-up security checks and surveillance, and new digital "cyber patrols" as officials link the moves to 2026 FIFA World Cup preparations. Officials and diplomats used social media to respond quickly; Mexico's president posted solidarity, Canada's foreign minister and the U.S. ambassador offered assistance on X, and public reaction has shown shock and calls for better protections.
