Gunman Opens Fire at Mexico's Teotihuacan Pyramids, Killing Canadian Tourist and Wounding 13
A gunman opened fire at Mexico's Teotihuacan pyramids Monday, killing a Canadian woman and wounding at least 13 people from the U.S., Colombia, Russia, Brazil, the Netherlands and Canada. The 27-year-old attacker, Julio César Jasso Ramírez from Guerrero, carried materials referencing the 1999 Columbine High School shooting, including an AI-modified photo showing him with the perpetrators. The attacker shot himself after National Guard members wounded him. The attack occurred on the 27th anniversary of the Columbine massacre and less than two months before Mexico co-hosts the 2026 FIFA World Cup.
