Mexican authorities have released new information about the attack that unfolded on the Pyramid of the Moon at Teotihuacan, roughly 30 miles north of Mexico City. Officials identified the suspect as Julio Jasso Ramírez and said he positioned himself atop the archaeological site, fired at visitors and verbally taunted rescue personnel. Prosecutors described threats in which he warned that he held hostages and would kill them if rescuers climbed the structure, and threatened to sacrifice anyone who moved.
Authorities say one Canadian tourist was killed and 13 others were wounded, including six U.S. citizens. Some victims suffered gunshot wounds; others were hurt while scrambling down the pyramid’s steep steps amid the chaos. Investigators recovered a backpack they say contained ammunition, knives, gloves and goggles. They also reported finding notes that appear to reference the 1999 Columbine school shooting and are probing how the attacker acquired his weapons, including possible purchases on the black market.
Tourists described sudden panic after the first shots. Greg Magadini of Boise, Idaho, told reporters that by the second shot it was obvious an active‑shooter situation, with people screaming, running and taking cover. Mexican officials have launched a criminal investigation to confirm details, determine motive and trace the attacker’s preparations and sources.
President Andrés Manuel López Obrador said authorities will implement measures to reduce the risk of a similar incident at tourist sites. Investigators continue to examine the suspect’s writings and movements as they piece together how the assault was planned and carried out.
