Sheinbaum Promises Teotihuacan Investigation, Addresses Chihuahua Diplomatic Row

At her April 21 mañanera, President Claudia Sheinbaum addressed two simultaneous security crises. On Teotihuacan: Sheinbaum promised a full investigation into the April 20 pyramid shooting that killed a Canadian tourist and injured 13 international visitors. She confirmed direct contact with the Canadian Embassy and said security at archaeological heritage sites would be reviewed. She stated the incident 'cannot and will not be repeated.' On Chihuahua: Sheinbaum continued to press the diplomatic controversy over the joint US-Mexico drug lab operation in Morelos, Chihuahua that preceded the fatal convoy crash of April 19. She noted the Chihuahua state prosecutor had already changed his public account of the operation, and that investigations were underway to determine whether the Constitution or relevant laws were violated by conducting a joint operation without informing the federal government. The simultaneous handling of both crises — a tourist security failure and a question of constitutional authority over foreign military or security personnel operating in Mexico — underscored the compound pressures on the Sheinbaum administration in the 51 days before the FIFA World Cup 2026 opening ceremony.
