Shooting At Teotihuacán’s Pyramid Of The Moon Sparks Security Concerns Ahead Of World Cup

Graphic footage of a gunman firing from the top of the Pyramid of the Moon in Teotihuacán and tourists lying motionless below has renewed worries about public safety in Mexico just weeks before the country co-hosts the World Cup.

At least one person — a Canadian woman — was killed in Monday’s attack at the Teotihuacán archaeological zone, about 30 miles (50 km) north of Mexico City. Authorities say seven other foreign nationals, including two Americans, suffered gunshot wounds, while an additional six visitors reported injuries sustained in the ensuing panic.

What Happened

State security officials received the first report of an armed man threatening visitors at roughly 11:20 a.m. local time, according to Cristóbal Castañeda Camarillo, secretary of security for the State of Mexico. Video from the site shows the attacker pacing on top of the Pyramid of the Moon while tourists lay on the ground nearby.

National Guard units arrived at the scene around 11:30 a.m. The assailant fired at the arriving guards, who returned fire and wounded him in the leg; the attacker then took his own life at the scene, officials said.

Perpetrator And Investigation

State prosecutors identified the shooter as 27-year-old Mexican national Julio César Jasso Ramírez. Authorities say he acted alone, had no known ties to organized crime or drug cartels, and that the attack appears to have been premeditated. Investigators reported evidence that the assailant had visited the archaeological zone multiple times and had stayed in nearby hotels before carrying out the attack.

Officials recovered a backpack containing handwritten notes referencing violent incidents in the United States in April 1999; the shooting took place on the 27th anniversary of the Columbine massacre.

Government Response And World Cup Security

President Claudia Sheinbaum described the incident as unprecedented for Mexico, said the attacker showed signs of psychological problems, and reiterated that the country remains safe for visitors. Mexican security officials have pledged to strengthen protection at archaeological sites and other public venues ahead of the World Cup.

Mexico is scheduled to host 13 World Cup matches from June 11 to July 5 across three cities; five matches are expected to be played in Mexico City. Security Secretary Omar García Harfuch said authorities will increase security at cultural sites in coordination with the Ministry of Culture and other agencies as a precaution.

Broader Context

The attack comes amid heightened tensions after the February killing of Nemesio “El Mencho” Oseguera Cervantes, leader of the Jalisco New Generation Cartel, which sparked episodes of violence in parts of the country. Authorities also point to recent successful large events, such as a March Shakira concert attended by hundreds of thousands, as evidence Mexico can manage big gatherings — though Monday’s shooting has prompted debate about whether officials can fully guarantee safety for tourists and residents during the tournament.
