Gunman who fired on tourists at Mexican pyramid carried materials related to 1999 Columbine massacre

MEXICO CITY (AP) — The gunman who opened fire on tourists at Mexico’s iconic Teotihuacan pyramids carried materials that were apparently related to the 1999 shooting at Columbine High School, authorities said Tuesday, a day after the attack that killed a Canadian woman and left at least 13 people injured.

Although officials did not mention Columbine by name, they referred to several books and handwritten notes that belonged to the gunman and referenced attacks in the United States in April 1999. Monday was the 27th anniversary of the massacre in Colorado.

Among the gunman's belongings was a photo modified by artificial intelligence showing him alongside the Columbine attackers, according to a state official who spoke to The Associated Press on the condition of anonymity because the official was not authorized to address the media.

Seven people were wounded by gunshots at the archaeological site north of the Mexican capital, the local government said. The nature of the other injuries was not disclosed, but some people fell when the shooting started, including some who were climbing on the pyramids.

The assailant, who acted alone, shot and killed himself, authorities said, and security officials found a gun, a knife and ammunition at the scene.

The attack happened less than two months before Mexico co-hosts the 2026 FIFA World Cup soccer tournament. Mexico's security secretary, Omar García Harfuch, said major tourist destinations would see a heightened presence of both ground forces and digital “cyber patrols” to prevent threats.

“Yesterday’s attack highlights the urgent need to strengthen our security protocols,” Mexican President Claudia Sheinbaum said. She also noted the importance of analyzing “external influences” that may provoke such violence within the country.

While such attacks are uncommon in Latin America, they are not unheard of. Earlier this month, Argentine authorities linked a teenager to the “true crime community” after the teen killed one student and wounded eight others at a school in the central province of Santa Fe. The community is an online subculture that emerged from forums established after the Columbine massacre to discuss and, in some cases, glorify such violence.

Taken to hospitals after the Mexico attack were six people from the U.S., three from Colombia, one from Russia, one from Brazil, one from the Netherlands and one from Canada, the local government said. The youngest person who was hurt was 6; the oldest was 61, Mexican authorities said.

Authorities identified the attacker as 27-year-old Julio César Jasso Ramírez, a native of Guerrero, Mexico, who, they said, arrived in Teotihuacan a day earlier in an Uber and stayed in a hotel.

Then on Monday shortly before noon, while atop the Pyramid of the Moon, he began firing at tourists with an old revolver while holding a plastic bag containing 52 .38-caliber cartridges in his other hand, said José Luis Cervantes Martínez, the attorney general of the state of Mexico, which includes Teotihuacan.

From the summit of the pyramid, the attacker opened fire on tourists and targeted approaching security forces. Some people threw themselves to the ground and lay motionless to avoid detection. Others fled down the structure as gunshots echoed, Cervantes Martínez said.

National Guard members eventually scaled the pyramid and wounded the attacker in the leg. Witnesses said the gunman shot and killed himself once he felt cornered, according to Cervantes Martínez.

The assailant carried a tactical-style backpack containing an analog cellphone and bus tickets, Cervantes Martínez said.

The attorney general also noted the presence of “literature, images and manuscripts" that related to "violent incidents known to have occurred in the United States in April 1999,” a likely reference to the Columbine attack in which 12 students and a teacher were killed.

Investigators built "a psychopathic profile" of the suspect that was "characterized by a tendency to copy situations that occurred in other places, at other times and involving other figures,’” he added.

Greg Magadini, of Boise, Idaho, was with a tour group on top of the pyramid when he heard a loud crack followed by screaming. The gunman was about 40 feet (12 meters) away on the same platform with roughly 60 tourists, he said.

Magadini jumped down a ledge and scrambled for cover while two of his friends stayed on the platform above trying to hide.

Shots seemed to ring out every five seconds, Magadini said, as he and the others jumped down more ledges to reach the ground. Then they ran through a field behind the pyramid, carrying one of his friends who badly injured her ankle on one of the jumps.

Magadini, who came away with scrapes and cuts, said he did not see the shooter, but his friends said the gunman seemed to fire randomly in all directions. “Everyone was a target,” he said.

Later at the hospital, they talked with other tourists, who said the shooter at one point played strange music and taunted them, saying he hated tourists, Magadini said.

The Teotihuacan pyramids, a UNESCO World Heritage Site, are a series of ancient structures on the outskirts of Mexico City. As one of Mexico’s most popular tourist destinations, the site drew more than 1.8 million international visitors last year, according to government figures.

Canadian Prime Minister Mark Carney offered condolences to the family and friends of the Canadian tourist who was killed. He said Canadian authorities were working with those in Mexico.

“It’s a terrible circumstance,” Carney said.

NEW YORK (AP) — Trains are rolling again on the Long Island Rail Road on Tuesday after a deal was reached to end a strike that had shut down the busiest commuter rail system in the country.

The first trains departed from Manhattan's Penn Station and Grand Central Terminal shortly after noon on Tuesday. Trains were also scheduled to depart from other stations on the four main branches of the system after that time, with full service expected to be back across all branches at 4 p.m. in time for the evening rush.

“It was a difficult circumstance, but I’m very happy and I’m very pleased that we’re back in business,” said Robert Free, president of the LIRR, shortly before the first trains departed. “We’re back to doing what we do best, and that’s providing service, and keeping this region moving.”

Commuters in the eastern suburbs of New York City still had to muddle through another tough morning rush hour, as trains weren't set to be running in time for the commute into work after the agreement was reached late Monday.

The LIRR still urged riders to work from home again Tuesday if possible. Shuttle buses were being offered from a handful of locations on Long Island to subway stations in New York City.

Five labor unions representing about half the train system’s workforce went on strike at 12:01 a.m. Saturday, halting service for roughly 250,000 commuters who use the rail system that connects New York City to its eastern suburbs every weekday.

Hallie Kessler was among the weary Long Island commuters who welcomed the strike's end. With the trains out of service, the 24-year old speech therapist commuted three hours home from her job at a public school in the New York City borough of Queens on Monday.

“Obviously I wish trains would be running when peak hours start so I could avoid the long morning commute, but happy to not deal with it in the afternoon when I’m leaving work,” Kessler said. “Curious what the deal says about future fares, which has been a big concern, but we’ll see.”

New York Gov. Kathy Hochul and railroad officials have said they're not at liberty to disclose details of the new contract terms until they're voted on and approved by union members. But the Democrat, who is up for reelection, stressed the deal won’t increase fares or taxes and will give unionized workers the fair wages they deserve.

The first impacts of the walkout were felt over the weekend, as baseball fans had to find other ways to get to Citi Field in Queens to see the New York Mets take on their crosstown rivals the New York Yankees.

Hochul said the deal ensures basketball fans won't meet the same fate as they travel to watch the New York Knicks continue their playoff run on Tuesday night at Madison Square Garden, which is located directly above the LIRR's Penn Station hub in Manhattan.

The unions — which represent locomotive engineers, machinists, signalmen and others — and the Metropolitan Transportation Authority had been negotiating a new contract since 2023, but talks had stalled over salaries and healthcare.

The unions have said raises were needed to help workers keep up with inflation and the rising cost of living in the New York City area. The MTA had said the union’s initial demands would lead to fare increases and set a difficult precedent for negotiations with other transit unions.

The strike was the first walkout for the LIRR since a two-day strike in 1994.
