TEOTIHUACÁN, Mexico — Authorities in Mexico are investigating a deadly and highly unusual shooting that occurred Monday at the Teotihuacán Archaeological Zone, one of the country’s most prominent tourist destinations. The incident resulted in two fatalities and at least 13 injuries, including several caused by gunfire. Officials confirmed that the victims include Li Desong, a Canadian tourist, and the alleged attacker, identified as 27 year old Julio César Jasso Ramírez, originally from Tlapa, Guerrero. The attack was first reported at approximately 11:20 a.m., when emergency services received calls of an armed individual opening fire on visitors near the Pyramid of the Moon. The suspect died from a self inflicted gunshot wound, authorities said, though some witness accounts suggest law enforcement may have engaged him before his death.

The Attack: Gunfire at the Pyramid of the Moon

The attack occurred at approximately 11:20 a.m. on Monday at the Teotihuacán Archaeological Zone, located about 30 miles northeast of Mexico City. Teotihuacán is one of the most famous archaeological sites in the world, known for its massive pyramids, including the Pyramid of the Sun and the Pyramid of the Moon. It is a UNESCO World Heritage Site and attracts millions of visitors annually. On a typical day, the site is filled with tourists from around the globe, climbing the ancient structures, taking photographs, and learning about the pre Columbian civilization.

According to preliminary findings, the suspect, Julio César Jasso Ramírez, ascended the Pyramid of the Moon, where dozens of tourists many of them foreign visitors were present. The Pyramid of the Moon is a large structure at the northern end of the Avenue of the Dead. It is a popular spot for tourists to climb and take in the view. On this day, it became a killing field.

Authorities report that the attacker discharged a handgun multiple times, firing in different directions toward individuals gathered on and around the pyramid. He was not targeting a specific person. He was firing indiscriminately. Everyone was a target. He shot at tourists from Canada, the United States, Colombia, Russia, Brazil, the Netherlands, and other nations.

Witness accounts and video footage circulating online show people attempting to shield themselves by lying face down or taking cover behind stone structures as the gunman moved about the elevated platform. Some victims jumped from elevated sections of the pyramid in an effort to escape, while others remained motionless to avoid drawing attention. The panic was intense. People were screaming, running, falling.

Eyewitnesses described a chaotic and terrifying scene, with shots reportedly fired at short intervals. One witness stated that “everyone was a target,” describing the shooting as indiscriminate.

The Victims: One Dead, 13 Injured

The attack resulted in two fatalities: Li Desong, a Canadian tourist, and the suspect himself, Julio César Jasso Ramírez. Li Desong was visiting Mexico, likely as a tourist, enjoying the ancient ruins. He was shot and killed by the attacker. He died at the scene or at a hospital. His family in Canada has been notified. They are devastated.

At least 13 other people were injured. Seven people sustained gunshot wounds. Six others suffered injuries such as fractures and trauma, reportedly sustained while attempting to flee the scene in panic. Some jumped from the pyramid. Some fell. Some were trampled. The injuries ranged from minor to serious.

Officials reported that the injured ranged in age from 6 to 61 and were in stable condition as of Tuesday morning. A 6 year old child was injured. A child, visiting an ancient pyramid with their family, was shot or injured in the chaos. That child will carry the memory of this day forever.

Victims included individuals from multiple countries, including the United States, Colombia, Russia, Brazil, the Netherlands, and Canada. The attack was international. Tourists from around the world were caught in the crossfire.

The Suspect: Julio César Jasso Ramírez, 27

The suspect was identified as 27 year old Julio César Jasso Ramírez, originally from Tlapa, Guerrero, a city in southern Mexico. He was a Mexican national. He was not a foreign terrorist. He was a local. He had conducted prior reconnaissance of the site, according to the State of Mexico Attorney General’s Office. He had been to Teotihuacán before. He had scouted the location. He had planned this attack.

Approximately 25 minutes after the initial attack, the suspect was found deceased. Authorities have stated that he died from a self inflicted gunshot wound. He shot himself. He killed himself after killing a Canadian tourist and injuring 13 others. However, some witness accounts and video evidence suggest law enforcement may have engaged the suspect before his death. Officials have not yet clarified the exact sequence of events. It is possible that police shot him, or that he shot himself as police closed in.

Investigators recovered a handgun, ammunition, and a knife at the scene, along with a backpack containing personal items, including written materials and electronic devices. He was armed with a gun and a knife. He was prepared to kill.

The Motive: Extremist Views and Fascination with Violence

According to the State of Mexico Attorney General’s Office, the suspect had conducted prior reconnaissance of the site. Authorities further indicated that materials recovered from the suspect referenced violent incidents in the United States dating back to April 1999. He was interested in past mass shootings. He may have been inspired by them.

Additional reports suggest the suspect had expressed extremist views and may have demonstrated fascination with historical figures associated with violence, though officials have not confirmed a definitive motive. Was he inspired by a specific ideology? Was he mentally ill? Was he seeking fame? The investigation will seek to answer these questions.

The materials recovered from the suspect referenced violent incidents in the United States. He was looking at American mass shootings. He may have been trying to copy them. He chose a tourist destination. He chose a place where people from many countries gather. He wanted to make a statement.

The Response: Security Concerns Ahead of the World Cup

The case has prompted heightened concern among Mexican officials, particularly given the country’s role as a co host of the upcoming 2026 FIFA World Cup. Mexico will host matches in the tournament, and millions of international visitors are expected. An attack on tourists at a major archaeological site raises questions about security.

In response, security measures at major tourist destinations are expected to be reinforced, including increased law enforcement presence and expanded surveillance efforts. The government does not want another attack. They want tourists to feel safe.

Mexican President Claudia Sheinbaum described the attack as deeply troubling and emphasized the need to strengthen national security protocols, while also examining potential external influences that may contribute to such acts of violence. She is concerned. She wants answers. She wants to prevent this from happening again.

The Community: Teotihuacán in Mourning

The Teotihuacán site, recognized as a UNESCO World Heritage Site, attracts millions of visitors annually and is considered a cornerstone of Mexico’s cultural heritage. The attack has shocked the nation. Mexicans are proud of their history, their culture, their ancient sites. An attack on tourists at Teotihuacán is an attack on Mexico itself.

The investigation remains ongoing as authorities work to establish a clear motive and reconstruct the sequence of events leading up to the attack. Officials have urged the public to rely on verified information as more details emerge.

Holding Onto Memories

As the investigation continues, the family of Li Desong, the Canadian tourist who was killed, is left to do the hardest work of all. They must hold onto their memories of him while also confronting the reality of his death. They must grieve his loss while also waiting for answers. They must find a way to go on without him.

Li Desong was a tourist. He was visiting Mexico to see the pyramids. He was excited. He was curious. He was looking forward to the trip. He did not expect to die. His family did not expect to receive a call that their loved one had been killed in a mass shooting at an ancient ruin.

The injured victims are recovering in hospitals. The 6 year old child is healing. The tourists from around the world are returning home, traumatized. They will never forget what they saw.

Conclusion: A Mass Shooting at the Pyramids

The deadly shooting at the Teotihuacán Pyramids near Mexico City killed Canadian tourist Li Desong and injured 13 others. The suspect, Julio César Jasso Ramírez, 27, died from a self inflicted gunshot wound. He had conducted prior reconnaissance of the site. He had expressed extremist views. He may have been inspired by past mass shootings. The investigation is ongoing.

As Mexico mourns, the nation stands together in grief, offering prayers and support to the victims and their families. Rest in peace, Li Desong. You were loved. You will be missed. And your memory will live on in the hearts of everyone who knew you. Gone too soon, forever remembered.
