Mass shooting at Teotihuacan archaeological site kills Canadian tourist, injures 13 international visitors

On April 20, Monday, a shooter opened fire from the Pyramid of the Moon at the Teotihuacan archaeological site in Mexico, resulting in the death of a Canadian woman and injuring 13 individuals from various countries, including Colombia, Russia, the U.S., Brazil, the Netherlands, and Canada, among them two children. The assailant, identified as 27-year-old Julio César Jasso Ramírez, took his own life. His shirt bore the words "Disconnect and Self-Destruct," suggesting a connection to online communities associated with the Columbine High School tragedy. Authorities concluded that the attack was premeditated and carried out by a single perpetrator. Teotihuacan, which is Mexico's second most-visited site, is set to reopen on April 22 with increased security measures, although the Pyramid of the Moon will remain closed indefinitely. Responses to the incident came from President Claudia Sheinbaum and Canada’s Foreign Minister Anita Anand.
