Gunman Kills Canadian Woman at Teotihuacán Pyramid of the Moon; 13 Others Injured Including 6 Americans

At approximately 11:30 a.m. on April 20, a lone gunman opened fire from atop the Pyramid of the Moon at the Teotihuacán archaeological zone northeast of Mexico City, killing one 32-year-old Canadian female tourist and injuring 13 others. The attacker was identified by the State of Mexico Attorney General's Office as Julio César Jasso Ramírez, 27, a Mexican national from Mexico City's Gustavo A. Madero borough. After opening fire, Jasso Ramírez died by self-inflicted gunshot. Among those injured were six Americans, three Colombians, one Russian, one Brazilian, one Dutch national, and one additional Canadian. Of the 13 injured, seven were treated for gunshot wounds while six suffered injuries from fleeing the scene. Witnesses reported more than 20 shots fired; Jasso allegedly ordered a group of visitors to lie down before repositioning and resuming fire. Teotihuacán is among Mexico's most visited archaeological sites, attracting over 4 million tourists annually. The attack immediately intensified security concerns about Mexico's readiness for the 2026 FIFA World Cup, for which three Mexican cities — Mexico City, Guadalajara, and Monterrey — will serve as host venues beginning June. President Sheinbaum said she 'expressed sincere solidarity with the affected individuals and their families' and instructed the Security Cabinet to thoroughly investigate. Canada's Foreign Ministry confirmed one citizen killed and one injured.
