A Canadian woman was killed and at least 13 others were injured when a gunman opened fire at the ancient Teotihuacán pyramids near Mexico City on Monday, April 20, 2026, according to multiple news outlets. The shooter, later identified as 27-year-old Julio César Jasso, died by suicide at the scene, authorities told Fox News.

Mexican President Claudia Sheinbaum expressed “deep pain” over the attack and ordered a thorough investigation, as reported by The Guardian and other outlets. “What happened today in Teotihuacan deeply pains us,” Sheinbaum wrote on social media, according to Reuters. “I express my most sincere solidarity with the affected individuals and their families.”

Coverage Comparison

Reporting on the incident has converged on the central facts: a Canadian woman was killed, multiple people were injured, and the gunman took his own life. However, the number of injured varies across sources. Al Jazeera, France 24, and The Guardian reported six or four injured, respectively, while the South China Morning Post and The Hindu reported 13 injured, a figure later confirmed by TASS, citing Mexico’s Secretariat of Security and Citizen Protection.

Reports also differ on the details of the shooter. Fox News, citing anonymous officials, identified him as Julio César Jasso, a Mexican national, and said he acted alone. The Guardian noted that authorities initially said the shooter's nationality was unknown. TASS reported that the shooter's identity had not been established as of the initial reports, though later updates confirmed Jasso's name.

The response from Mexican authorities has been consistent across sources. Sheinbaum ordered an investigation and said federal and state security forces were deployed to the site. The Security Cabinet confirmed that personnel from the Interior and Culture secretariats were heading to the site to provide assistance, as quoted by Fox News and Reuters.
