Gunman Kills Canadian Tourist, Injures 13 at Mexico's Teotihuacán Pyramids
A 27-year-old gunman opened fire at the Teotihuacán archaeological site, resulting in one death and multiple injuries before taking his own life.
On April 20, 2026, a gunman opened fire from atop the Pyramid of the Moon at Mexico's Teotihuacán archaeological site, killing a Canadian woman and injuring 13 others. The assailant, identified as 27-year-old Julio César Jasso Ramírez, later died from a self-inflicted gunshot wound.
Among the injured were tourists from the United States, Colombia, Brazil, Russia, the Netherlands, and Canada, ranging in age from 6 to 61. Seven individuals sustained gunshot wounds, while others were hurt during the ensuing panic.
Authorities reported that Jasso Ramírez carried materials referencing the 1999 Columbine High School massacre, including AI-generated images depicting himself alongside the Columbine shooters. He also wore a T-shirt bearing a phrase associated with the Columbine attack.
In response to the incident, President Claudia Sheinbaum announced plans to enhance security measures at tourist sites, including increased National Guard deployments and the installation of metal detectors at archaeological locations. She emphasized the need for stricter controls to prevent individuals from entering tourist areas with firearms.
The Teotihuacán pyramids, a UNESCO World Heritage site and major tourist destination, have been closed indefinitely as authorities investigate the attack.
