Mexico files treason case against ex official over CIA deaths

The legal battle over the deaths of two American intelligence officers has escalated into a high stakes test of Mexico's sovereign limits.

The incident occurred on April 19 during a state led operation to dismantle a large chemical drug laboratory in the mountainous municipality of Morelos in Chihuahua. On the return journey from the site, a vehicle in the convoy veered off the road and fell into a ravine. The crash killed four people: two Mexican state officials and two U.S. nationals. The Mexican victims were identified as Pedro Román Oseguera Cervantes, the first commander of the state investigation agency, and officer Manuel Genaro Méndez Montes. The targeted facility was described by local authorities as one of the largest sites in the country for the production of chemical drugs. No arrests were made at the time because the suspects managed to flee the scene.

César Jáuregui, the former attorney general of Chihuahua, initially described the two Americans as instructor officers engaged in training tasks under binational anti drug cooperation. He later resigned to facilitate an inquiry into the event. On October 17, he was arrested on state charges of illegally exercising public office. A judge ruled on Thursday that these state charges can proceed to trial. Federal prosecutors have since added a charge of treason. A federal judge is scheduled to decide on Saturday whether to allow this federal indictment to move forward.

Federal officials argue that Jáuregui endangered national security by approving the participation of U.S. agents in a field operation, a decision that is reserved for the federal government. The treason charge carries a potential sentence of five to 40 years in prison, though it is considered difficult to prove. Defense attorney Héctor Villasana stated that prosecutors told a closed hearing they sought an exemplary punishment to prevent a situation similar to the U.S. removal of Venezuelan President Nicolás Maduro. The U.S. State Department said it is aware of and monitoring the case, but it did not link the legal proceedings directly to the deaths of the two officers.

Legal experts express doubt that the treason charge will ultimately hold up in court. Samuel González, a former chief prosecutor for organized crime, noted that while Jáuregui may have failed in his duties by not informing federal authorities or by allowing foreign agents to carry weapons, this does not typically amount to treason, which he described as a crime of war. Carlos Pérez Ricart of CIDE university suggested that the case will have a significant public impact regardless of the outcome. He characterized the decision as a political move ahead of the 2027 midterm elections and warned that it sends a very bad signal to Washington.

Accounts regarding the specific roles of the Americans have varied since the crash. U.S. Ambassador Ronald Johnson referred to them as embassy personnel. However, multiple people familiar with the matter later told CBS News that they were CIA agents. The CIA declined to comment on the matter. Mexico's security ministry stated that one agent entered as a visitor and the other with a diplomatic passport. The ministry noted that neither had formal accreditation for operational activities. Two other U.S. agents who were traveling in a separate vehicle were later expelled from the country. President Claudia Sheinbaum stated that none of the agents had permission to operate in Mexico.

This case highlights the ongoing tension in how U.S. agencies operate within Mexican borders. Former President Andrés Manuel López Obrador previously limited these activities. President Sheinbaum has since amended the Constitution to bar field operations without express Mexican authorization. Pérez Ricart observed that such actions have often occurred without federal knowledge and that the lack of clear rules can lead to abuses. The case now serves as a flashpoint for broader questions about foreign involvement in Mexican law enforcement.
