A 27-year-old gunman climbed halfway up a nearly 2,000-year-old pyramid at one of Mexico's most famous archaeological sites Monday morning, took tourists hostage, and opened fire, killing a Canadian woman and wounding 13 others before turning the gun on himself. Mexican authorities identified the shooter as Julio Cesar Jasso of Mexico, a state official told the Associated Press on condition of anonymity.
The attack unfolded just after 11:30 a.m. at the Pyramid of the Moon in the Teotihuacan ruins, a sprawling pre-Columbian complex that draws visitors from around the world. Among the injured were six Americans, three Colombians, two Brazilians, one Russian, and one Canadian, all hospitalized. The youngest victim was six years old. The oldest was 61.
No motive has been disclosed. Security officers recovered a gun, a knife, and ammunition at the scene. The archaeological site was closed until further notice.
Witness Laura Torres described the scene to media including N+ Noticias. She said she watched from below as Jasso held tourists on the pyramid's platform.
"I saw the guy that was shooting up on the pyramid and yes, there were a lot of people, he had people as hostages."
Torres recounted a harrowing sequence in which the gunman appeared to release some captives one at a time, as reported by the New York Post:
"In the short time I saw him let someone go down, a girl, he let her go down. For a moment I thought he was going to shoot her in the back, but no, thank God, he let her go. Then a bit later he let a boy go, but the hostages stayed there."
Another witness, Brenda Lee of Vancouver, British Columbia, told the AP that the scene was packed when the shooting started.
"There were thousands of people there and there were a lot of gunshots that just kept coming."
Video shared on social media by journalist Ricardo Ospina appeared to show the shooter raising his gun and firing at one of the victims from the pyramid's elevated platform. Mexican officials said seven of the 13 wounded were struck by gunfire. Breitbart reported that two others were hurt in falls while trying to escape.
Mexican President Claudia Sheinbaum addressed the attack on X, saying she had been in touch with the Canadian Embassy and had instructed Mexico's security cabinet to investigate.
"What happened today in Teotihuacán deeply pains us. I express my most sincere solidarity with the affected individuals and their families."
Sheinbaum pledged the incident would be "thoroughly investigated." Canada's foreign affairs minister, Anita Anand, confirmed the loss. "As a result of a horrific act of gun violence, a Canadian was killed and another wounded in Teotihuacán," Anand said, as Newsmax reported.
The name of the slain Canadian woman has not been publicly released.
The Pyramid of the Moon sits at the north end of the Street of the Dead, opposite the larger Pyramid of the Sun. Built between 100 and 450 C.E., the complex predates the Aztec civilization and remains one of Mexico's most visited heritage sites. Tourists routinely climb its steps for panoramic views of the ancient city.
That a gunman could ascend the structure armed with a firearm, a knife, and extra ammunition, in broad daylight, surrounded by thousands of visitors, and hold hostages before killing and wounding over a dozen people raises hard questions about security at the site. Those questions have not been answered.
The incident comes amid a broader climate of deadly gun violence across Mexico. Fox News noted the shooting took place against the backdrop of instability following the reported death of cartel leader El Mencho, which has triggered a wave of attacks throughout the country.
Mexico's security challenges are not confined to cartel strongholds. Violent crime has increasingly touched areas that depend on tourism and international visitors. The abduction of an American woman in Mexico recently drew attention to the dangers facing foreign nationals in the country.
For the six Americans wounded Monday, the shooting is a grim reminder that lawlessness in Mexico is not an abstraction. It lands on real people, families on vacation, children as young as six, at sites that are supposed to be safe.
Authorities have not disclosed a motive for Jasso's attack. They have not explained how he entered the archaeological site armed. They have not said how long the hostage standoff lasted or what time the shooting ended. The identities and conditions of the victims beyond their nationalities and ages remain unreleased.
These are not minor gaps. A mass shooting at a world-famous landmark, with victims from at least five countries including the United States, demands more than a social media post and a pledge to investigate. The families of the injured, and American taxpayers who fund diplomatic and consular services, deserve a full accounting.
The broader pattern of violent crime against innocent people is not limited to Mexico, of course. But when American citizens are shot while visiting a foreign country's most prominent tourist attraction, it is fair to ask what security measures existed, and why they failed.
Mexico has some of the strictest gun laws in the Western Hemisphere on paper. A single legal gun store operates in the entire country, run by the military. Yet a 27-year-old man walked into a crowded archaeological site with a firearm, a bladed weapon, and live ammunition in the middle of a Monday morning.
Cross-border law enforcement cooperation between the U.S. and Mexico has produced results in individual cases. But incidents like the Teotihuacan shooting expose a deeper problem: the gap between Mexico's stated commitment to public safety and the reality on the ground.
Sheinbaum's government promised a thorough investigation. The victims and their families, and the Americans among them, will be watching to see whether that promise amounts to anything more than words on a screen.
Strict gun laws did not stop this. Thousands of witnesses did not deter it. And a nearly 2,000-year-old monument to human achievement became, for one Monday morning, a monument to the cost of security failures that no one in power seems eager to explain.
