Teotihuacán Attack: Mother Thought Son Was Missing, Suspect Identified, Video Released, Victim Recovering, Body Returned to Family

A man fatally shot a Canadian woman and injured several others before killing himself Monday at Mexico’s Teotihuacán pyramids, according to authorities.

The Mexican attorney general’s office identified the gunman as Julio César Jasso of Mexico and authorities said he acted alone. Thirteen people from different countries suffered a range of injuries, including six Americans, seven of whom were wounded by gunfire, Mexico’s security cabinet said. The ages of the injured range from 6 to 55.

Of the seven people who were shot, Mexican authorities identified two as American, two as Colombian, one as Canadian, one as Russian and one as Brazilian. In addition to the gunshot victims, four Americans, one Brazilian and another Colombian were also hurt, the security cabinet said.

The cabinet said early Tuesday that five of the victims had been released from the hospital — the four Americans who were not shot and the Brazilian who was shot.

Social media videos verified by NBC News appear to show a man standing with a gun on top of a pyramid while people duck for cover.

The Mexican Foreign Affairs Ministry said it is in contact with “other embassies of affected individuals to provide timely follow-up on these events.”

Canadian Foreign Affairs Minister Anita Anand said officials were in touch to provide assistance. “As a result of a horrific act of gun violence, a Canadian was killed and another wounded in Teotihuacán, Mexico,” Anand said in a post on X. “My thoughts are with their family and loved ones.”

On 20 April 2026, a mass shooting occurred at the Teotihuacan archaeological site in the State of Mexico, Mexico. 27-year-old Julio César Jasso Ramírez opened fire from atop the Pyramid of the Moon, killing a Canadian woman and injuring 13 other tourists before committing suicide.

The shooting began at just after 11 a.m. At the Pyramid of the Moon, one of the most prominent structures at the site outside Mexico City, according to the witness, who had just descended from the temple’s mezzanine when they heard “pops” and saw a stampede of visitors.

The gunman remained at the top of the mezzanine, the witness said, adding that he appeared to fire most shots into the air, rather than directly at people, while carrying a digital tablet and shouting.

Bystanders, including some with medical training, provided first aid to the injured, using water bottles and clean cloths to slow bleeding until paramedics arrived, the witness added.

Security authorities said some of the injured had been taken to hospitals, including three Colombians, one of whom was a 6-year-old child, as well as U.S., Russian and Brazilian nationals.

A second Canadian was also wounded in the attack, according to a post on X from Canada’s Foreign Affairs Minister Anita Anand.

President Claudia Sheinbaum said in a post on social media: “What happened today in Teotihuacan pains us deeply. I express my deepest sympathy to those affected and their families.”
