Mexican authorities say a gunman opened fire at the Pyramid of the Moon in the Teotihuacan archaeological zone, killing one tourist and wounding others before taking his own life. A Canadian visitor was killed. Injured people included nationals from Canada, Colombia, Russia, Brazil and the United States.
Officials reported the attacker acted alone. Investigators recovered a firearm, a knife and a bag with 52 rounds of ammunition. He wore a tactical-style backpack that contained an analog cellphone and bus tickets. The suspect, identified as a 27-year-old man from Guerrero state, began shooting from the top of the Pyramid of the Moon; some visitors hid motionless while others fled the site. Security forces engaged the shooter and wounded him in the leg; he then fatally shot himself.
Authorities said they found books and handwritten notes referencing attacks in April 1999 — widely understood to refer to the Columbine school shooting — and an AI-altered photograph that showed the suspect alongside the Columbine attackers. The incident occurred on the 27th anniversary of the Columbine massacre.
“This act was not spontaneous,” Jose Luis Cervantes, attorney general of the State of Mexico, said at a press conference held with President Claudia Sheinbaum. Cervantes described the suspect as having a “psychopathic profile” and a tendency to imitate violent events involving others in different times and places.
Investigations are ongoing as officials continue to interview witnesses and review evidence from the scene.
