Former Chihuahua Prosecutor Faces Treason Trial Over Joint CIA Operation

César Jáuregui, the former attorney general of the Mexican state of Chihuahua, is set to stand trial on charges of treason after prosecutors alleged he authorized a joint law enforcement operation with American agents without notifying the federal government. The legal action places Jáuregui at the center of a growing debate regarding the extent of foreign involvement in Mexican domestic security matters. A federal judge is scheduled to decide this Saturday whether to formally accept the indictment, which would move the case into the next phase of litigation.

The controversy stems from a raid conducted on April 19 to dismantle a chemical drug laboratory in the Morelos municipality. At the time, the Chihuahua Attorney General's Office announced the successful takedown of what Jáuregui described as one of the largest drug production sites in the country. However, the operation ended without arrests as suspects fled the scene. During the return journey, a vehicle in the convoy left the road and fell into a ravine, resulting in the deaths of four individuals: two Mexican state officials and two Americans.

The deceased Mexican officials were identified as Pedro Román Oseguera Cervantes, the first commander of the state investigation agency, and officer Manuel Genaro Méndez Montes. Jáuregui initially characterized the two Americans as instructor officers engaged in training tasks under binational anti-drug cooperation protocols. The incident quickly escalated into a political issue, prompting Jáuregui to resign in order to facilitate a transparent inquiry into the events.

Jáuregui was arrested on October 17 on state charges of illegal exercise of public office, and a judge ruled this week that those state charges can proceed to trial. Subsequently, federal authorities added the treason charge, arguing that Jáuregui endangered national security by permitting U.S. participation in a field operation, a decision that is constitutionally reserved for the federal government. The charge carries a potential sentence of five to forty years, though it is widely regarded as difficult to prove in court.

Defense attorney Héctor Villasana stated that prosecutors indicated during a closed hearing that they sought an exemplary punishment to prevent a recurrence of situations similar to the U.S. removal of Venezuelan President Nicolás Maduro. Meanwhile, the U.S. State Department confirmed it is monitoring the case closely, although it has not publicly linked the legal proceedings directly to the deaths of the American agents.

Legal analysts remain skeptical about the viability of the treason charge. 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 conduct likely does not meet the definition of treason, which he described as a crime applicable during wartime. Carlos Pérez Ricart of CIDE university argued that the case will have a significant public impact regardless of the outcome, labeling it a political decision made ahead of the 2027 midterm elections that sends a negative signal to Washington.

Accounts regarding the specific roles of the deceased Americans have remained inconsistent. U.S. Ambassador Ronald Johnson referred to them as embassy personnel, while multiple sources familiar with the matter identified them as CIA agents. The CIA has declined to comment on the incident. Mexico's security ministry reported that one individual entered as a visitor and the other used a diplomatic passport, with neither holding 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 has emphasized national sovereignty, stating that none of the agents had permission to operate in Mexico. She previously amended the constitution to prohibit field operations without express Mexican authorization, following earlier limitations placed by former President Andrés Manuel López Obrador. Pérez Ricart warned that without clear rules, such actions could lead to abuses, noting that U.S. agencies have historically operated in Mexico without full federal knowledge.
