Two Central Intelligence Agency (CIA) officers were killed in a vehicle crash in Chihuahua, Mexico, on April 19 while returning from a counternarcotics operation, multiple sources confirmed Tuesday.

Their vehicle, part of a six-car convoy, skidded off a mountain road and fell into a ravine, where it exploded, Chihuahua Attorney General César Jáuregui said. Two officials from the Chihuahua State Investigation Agency (AEI) also died, identified by state prosecutors as first commander Pedro Román Oseguera Cervantes and officer Manuel Genaro Méndez Montes.

U.S. Ambassador Ronald Johnson, who spent 20 years with the CIA before his April 2025 Senate confirmation as ambassador, publicly identified the two Americans only as “U.S. Embassy personnel” in a post on X. Johnson made no mention of their CIA affiliation.

Mexican President Claudia Sheinbaum ordered federal prosecutors Tuesday to investigate whether the operation violated Mexico’s National Security Law, which bars joint foreign operations without prior federal authorization. “The security cabinet was not aware of the operation,” she said. “We were not informed.”

Jáuregui described the two Americans on Sunday as “instructor officers” doing “training work” and said Monday they were “eight or nine hours’ drive” from the lab site.

The Mexican Security Cabinet later confirmed the army and Chihuahua state prosecutors ran a joint operation in Morelos municipality that weekend, dismantling what Jáuregui called “perhaps one of the largest” synthetic drug production sites ever found in Mexico.

The CIA has expanded its presence in Mexico under Director John Ratcliffe, including surveillance flights with unarmed MQ-9 Reaper drones and cooperation with vetted Mexican military units, according to a September 2025 Reuters investigation.

The agency told CNN last year that “countering drug cartels in Mexico and regionally is a priority for CIA.”
