Gunman atop Pyramid of the Moon at Teotihuacan kills one Canadian tourist and wounds 13 before taking his own life

On April 20, at approximately 11:30 a.m. local time, Julio César Jasso Ramírez, 27, a Mexican national, opened fire from the Pyramid of the Moon at the Teotihuacan archaeological site roughly 30 miles northeast of Mexico City, killing one Canadian woman and wounding at least 13 others; Mexico's security cabinet reported seven wounded by gunshot and six injured in falls, with those hospitalized including six Americans, three Colombians, two Brazilians, one Russian, one Dutch national, and one Canadian. The State of Mexico security secretary said National Guard personnel arrived within ten minutes, exchanged fire with the shooter, and wounded him in the leg before he died of a self-inflicted gunshot at 11:45 a.m. State Attorney General José Luis Cervantes Martínez stated that investigators recovered from the shooter's backpack a firearm, a bladed weapon, live ammunition, and written materials referencing violent incidents in the United States in April 1999, which he declined to characterize further pending investigation. The National Institute of Anthropology and History closed the site until further notice, and Mexico's security cabinet confirmed Jasso Ramírez acted alone.
