Gunman opens fire at Teotihuacan pyramids in Mexico, killing one Canadian tourist and injuring others before dying by suicide

A gunman opened fire on tourists at the Teotihuacan archaeological site north of Mexico City on Monday, killing one Canadian woman and injuring multiple others before dying from a self-inflicted gunshot wound. The shooter, identified as 27-year-old Julio César Jaso Ramírez, a Mexican national, fired from atop the Pyramid of the Moon. Mexican officials said the attacker showed signs of psychological issues and appeared influenced by violent acts in the United States, with materials referencing events believed to be tied to the 1999 Columbine massacre found on his person.
