Gunman Kills Canadian Tourist, Injures 13 at Mexico's Teotihuacan Pyramids
A 27-year-old gunman opened fire at the Teotihuacan archaeological site, resulting in one Canadian tourist's death and injuries to 13 others before taking his own life.
On April 20, 2026, a gunman opened fire at the Teotihuacan pyramids near Mexico City, killing a Canadian woman and injuring 13 others. The assailant, identified as 27-year-old Julio César Jasso Ramírez from Guerrero, Mexico, acted alone and later died from a self-inflicted gunshot wound.
The victims included tourists from Canada, the United States, Colombia, Russia, Brazil, and the Netherlands, ranging in age from 6 to 61. Seven individuals sustained gunshot wounds, while others were injured during the ensuing panic.
Authorities discovered that Jasso carried materials referencing the 1999 Columbine High School massacre, including AI-generated images depicting himself alongside the Columbine shooters. He also possessed a revolver, a knife, and over 50 rounds of ammunition.
In response to the attack, Mexican President Claudia Sheinbaum announced plans to enhance security measures at tourist sites, emphasizing the need for stricter controls to prevent similar incidents. The Teotihuacan archaeological site has been closed indefinitely as investigations continue.
