Mexico Identifies Teotihuacan Pyramid Gunman Who Killed Canadian Tourist

Mexican authorities have identified the gunman who opened fire at Teotihuacan, killing a Canadian tourist and injuring others.

Officials named him as 27-year-old Mexican national Julio Cesar Jasso, who police say died from a self-inflicted gunshot wound at the site. Authorities said he was the sole assailant and was found with a gun, a knife and ammunition. Witnesses described him standing atop the Pyramid of the Moon and firing as tourists tried to descend, with some victims injured by falls. Authorities reported one Canadian killed and at least 13 people injured, including six Americans, three Colombians, one Russian, two Brazilians and one Canadian, with ages of the wounded ranging from 6 to 61 years old.

Mexico's National Institute of Anthropology and History closed the Teotihuacan archaeological site until further notice. President Claudia Sheinbaum said the shooting will be investigated and she is in touch with the Canadian embassy. Canadian Foreign Minister Anita Anand confirmed one Canadian dead and another wounded and released a statement on social media. U.S. Ambassador Ronald Johnson expressed concern and said the United States is ready to support Mexican authorities. Local guides and visitors on social media questioned lapses in routine entry screenings, noting that security scans used to be more common.

Initial reports focused on the shooting and unclear motive without identifying the attacker. Follow-up reporting by outlets including NPR and Fox named Julio Cesar Jasso, clarified that he acted alone and died by suicide, and added details about weapons and casualties. That shift moved coverage from immediate emergency accounts toward an investigation framed by questions about security at a major tourist site.
