Authorities have identified the gunman responsible for a deadly shooting at a major archaeological site in Mexico that left one tourist dead and more than a dozen others injured, as reported by Fox News.

Officials said 27-year-old Julio Cesar Jasso, a Mexican national, carried out the attack Monday at the Teotihuacán complex, one of the country’s most visited landmarks. A state official confirmed Jasso’s identity while speaking anonymously because they were not authorized to publicly discuss the case.

According to authorities, Jasso opened fire shortly after 11:30 a.m. while dozens of visitors were gathered at the top of the Pyramid of the Moon. The site, located just outside Mexico City, draws millions of tourists each year.

Officials said seven victims were struck by gunfire. Additional injuries occurred as people attempted to flee the scene, with some falling while trying to descend the pyramid structures during the panic.

Victims ranged in age from 6 to 61, and those hospitalized included tourists from multiple countries, including the United States, Colombia, Russia, Brazil, and Canada.

A Canadian tourist was killed in the attack, and another Canadian was among those wounded.

Authorities reported that Jasso acted alone. Security personnel later recovered a firearm, a knife, and ammunition at the scene. After carrying out the attack, Jasso died by suicide.

Video circulating in local media appeared to show the suspect positioned atop the pyramid as visitors rushed away below, with gunfire echoing across the area.

Mexican officials said the investigation is ongoing. Security procedures at the site have reportedly changed in recent years, with routine entry screenings no longer consistently enforced, according to a local guide familiar with the area.

Claudia Sheinbaum addressed the incident in a public statement, confirming that authorities would conduct a full investigation and noting communication with Canadian officials.

"What happened today in Teotihuacán deeply pains us. I express my most sincere solidarity with the affected individuals and their families," Sheinbaum said.

Canada’s foreign affairs minister, Anita Anand, also responded publicly, confirming the death of a Canadian citizen.

"As a result of a horrific act of gun violence, a Canadian was killed and another wounded in Teotihuacán," Anand said. "My thoughts are with their family and loved ones."

U.S. Ambassador to Mexico Ronald Johnson issued a statement later in the day expressing concern about the violence and the number of casualties.

He said he was expressing "deep concern" and sadness over the deaths and injuries and added that the United States is "ready to provide support as needed while Mexican authorities continue their investigation."

Following the shooting, Mexico’s National Institute of Anthropology and History announced that the Teotihuacán site would remain closed until further notice.
