Terror broke out in the archaeological zone of Teotihuacán this Monday, April 20, 2026, when a man unleashed a shootout from the top of the Pyramid of the Moon. The attacker, a resident of Mexico City, climbed the 43 meters of the structure and opened fire on visitors who were walking through the main square. This violent act claimed the life of a Canadian tourist and left six other people injured, including Russian and Colombian citizens, before the shooter decided to take his own life at the top of the monument.
Finding of the aggressor’s arsenal and symbols
Authorities discovered chilling details when inspecting the body of the attacker, who planned the attack with lethal precision. The subject was wearing a t-shirt with the phrase “Natural Selection”a replica of the garment worn by Eric Harris during the Columbine High School massacre in 1999. In addition to this macabre reference, the man was carrying a hunting rifle, a knife, multiple useful cartridges and various materials that contained references to the extinct Soviet Union, which reveals a deep ideological radicalization.
Panic took over the archaeological zone in a matter of seconds, forcing dozens of families to seek refuge between the ancient stone walls. Paramedics from the IMSS-Bienestar system transported the injured to the Axapusco General Hospital, where doctors are treating four people for direct gunshot wounds and two more for fractures and sprains suffered during the human stampede. A seventh person receives psychiatric treatment after experiencing a severe anxiety crisis when witnessing the murder of the Canadian citizen.
Government response and diplomatic coordination
Security mobilization reached unprecedented levels to protect the perimeter of the tourist site. Cristóbal Castañeda, Secretary of Security of the State of Mexico, coordinated the actions together with the National Guard and the State Prosecutor’s Office to secure ballistic evidence and protect the survivors. Simultaneously, President Claudia Sheinbaum Pardo established direct communication with the Canadian Embassy to expedite the repatriation procedures and provide comprehensive support to the bereaved.
Balance of victims and injured admitted
- Fatal victims: 2 (A Canadian tourist and the attacker).
- Injured by firearm: 4 people (Canadian, Colombian and Russian nationalities).
- Injured by physical trauma: 2 people (fractures and sprains).
- Psychiatric care: 1 person due to severe anxiety crisis.
Criminological analysis: the imitator or copycat effect
Understanding the root of this tragedy requires analyzing the psychological phenomenon that experts call the “copycat effect.” Security specialists warn that certain emotionally unstable individuals consume violent propaganda on Internet forums and decide to replicate historical crimes to obtain posthumous notoriety.
The use of the “Natural Selection” T-shirt demonstrates that the Teotihuacán shooter studied the methods and aesthetics of the Columbine killers, a pattern that intelligence agencies frequently detect in lone attackers. This profile fits into the “lone wolf” category, describing a person who acts without the support of a terrorist network or organized crime cartel. These aggressors plan their actions clandestinely, acquire hunting weapons with fewer legal restrictions and choose targets with high traffic to maximize the media impact.
Vulnerability of historic sites to new threats
The entry of a hunting rifle into the archaeological zone exposes a critical gap in security protocols. The custodians of the National Institute of Anthropology and History (INAH) focus their reviews on preventing damage to cultural heritage, but they lack advanced metal detectors or perimeter security arches capable of identifying long weapons. This tragedy will force federal authorities to redesign access filters and implement non-invasive scanning technologies.
The international repercussion threatens to severely impact the country’s tourism industry. The embassies of Canada, Russia and Colombia are already monitoring the medical evolution of their compatriots, while travel agencies are evaluating issuing security alerts. The pyramids of Teotihuacán receive more than 1.5 million tourists annually and are a UNESCO World Heritage Site, which raises the seriousness of the event to a global scale.
Testimonies from the epicenter of the attack
Laura Torres, a visitor who entered through door 3, reported that she observed the subject in the pyramid shooting towards the crowd. He explained that the gunman was wearing a shirt and jeans; He even freed a couple of people before continuing the attack. “First sporadic explosions began to be heard, then one after another, there were more than 20. The guides began to take people out, some panicked,” the witness said, highlighting the lack of effective screening protocols at the time of entry.
The Minister of Foreign Affairs of Canada, Anita Anand, confirmed the death of her compatriot and described the event as a horrendous act of armed violence. For its part, the Ministry of Foreign Affairs (SRE), headed by Roberto Velasco Álvarez, maintains timely monitoring and works in coordination with federal authorities to provide support to affected foreigners. The site remains under absolute protection while the Attorney General’s Office of the State of Mexico carries out the corresponding expert tests.
