Two U.S. Embassy instructor officers specializing in drone operations and counter-narcotics tactics died alongside the director of Chihuahua’s state investigation agency and a state officer April 19, when the lead vehicle in an official five-car convoy skidded off a mountain road near Morelos and fell into a ravine, exploding.

Chihuahua Attorney General César Jáuregui Moreno identified the Mexican victims as Agencia Estatal de Investigación (AEI) Director Pedro Román Oseguera Cervantes and AEI officer Manuel Genaro Méndez Montes. The U.S. Embassy declined to name the two Americans or specify which government agency they represented, saying only that they were “supporting Chihuahua state authorities’ efforts to combat cartel operations.”

The Americans’ role as drone-instructor officers became a flashpoint Monday, when Jáuregui revised his initial account. He said the pair had been conducting training activities “eight to nine hours away” from an operation that separately destroyed six clandestine synthetic drug laboratories in Morelos municipality over April 18 and 19, and had met with AEI Director Oseguera Cervantes only as his convoy returned from the raid. Jáuregui called the lab sites among “the largest found in the country where chemical drugs were produced.”
The three-month investigation that located the labs relied on drone surveillance, state officials said.
Mexican President Claudia Sheinbaum said Monday her government had no prior knowledge of U.S. personnel operating in Chihuahua. “It was not an operation that the security cabinet was aware of,” she said. “We were not informed; it was a decision by the Chihuahua government.” She said she would assess whether the collaboration violated Mexican national security law and would arrange a meeting between Johnson and Mexico’s foreign minister.

Sheinbaum’s statements came as U.S. Trade Representative Jamieson Greer arrived in Mexico City for the second round of United States-Mexico-Canada Agreement (USMCA) negotiations, and on the same day the Trump administration announced visa restrictions on 75 family members and business associates of individuals sanctioned under the Sinaloa Cartel designation.
“This tragedy is a solemn reminder of the risks faced by those Mexican and U.S. officials who are dedicated to protecting our communities,” Ambassador Johnson wrote on X.
