Mexico Files Treason Charge Against Former Chihuahua Prosecutor

The legal case against César Jáuregui, the former attorney general of Chihuahua, has escalated from a local state inquiry to a federal treason trial, marking a significant shift in how Mexico handles cooperation with American law enforcement. The core of the dispute centers on whether a state official had the authority to authorize U.S. agents to participate in a field operation without notifying the federal government. If convicted, Jáuregui could face a prison sentence of between five and 40 years, a penalty that legal experts argue is rarely applied in peacetime contexts.

The incident originated from a raid on a drug laboratory in the municipality of Morelos in April. The Chihuahua Attorney General's Office announced the successful dismantling of the site, which Jáuregui described as one of the largest chemical drug production facilities in the country. However, the operation concluded without any arrests as the suspects escaped. During the return journey, a vehicle in the convoy left the road and crashed into a ravine, killing four people. The victims included two Mexican state officials, Pedro Román Oseguera Cervantes and Manuel Genaro Méndez Montes, as well as two American citizens.

At the time of the crash, Jáuregui characterized the Americans as instructor officers engaged in training tasks under binational anti-drug cooperation. This explanation has since been complicated by conflicting accounts regarding their official status. U.S. Ambassador Ronald Johnson initially referred to them as embassy personnel, while individuals familiar with the matter later identified them as Central Intelligence Agency agents. The CIA has declined to comment on the case. Mexico's security ministry noted that one individual entered the country as a visitor and the other held a diplomatic passport, and that neither had formal accreditation for operational activities.

The deaths of the two Americans have become a political flashpoint under President Claudia Sheinbaum, who has prioritized national sovereignty. Sheinbaum stated that none of the U.S. agents had permission to operate on Mexican soil. Following the incident, two other U.S. agents traveling in a separate vehicle were expelled from the country. Jáuregui resigned to allow for an investigation and was arrested on October 17 on state charges of illegally exercising his public office. A judge recently ruled that these state charges can proceed to trial, and federal authorities have since added the treason count.

Federal prosecutors argue that Jáuregui endangered national security by approving the participation of foreign agents in a field operation, a power reserved for the federal government. In a closed hearing, defense attorney Héctor Villasana stated that prosecutors sought an exemplary punishment to prevent a scenario similar to the U.S. removal of Venezuelan President Nicolás Maduro. The U.S. State Department said it is monitoring the situation but has not explicitly linked the case to the CIA deaths.

Legal scholars remain skeptical that the treason charge will survive scrutiny. Samuel González, a former chief prosecutor for organized crime, noted that while Jáuregui may have failed in his duties by not informing federal authorities, treason is traditionally considered a wartime crime. Carlos Pérez Ricart of CIDE university suggested that the case is a political decision ahead of the 2027 midterm elections and warned that the proceedings send a negative signal to Washington.

The case highlights broader tensions regarding the presence of U.S. agencies in Mexico. Former President Andrés Manuel López Obrador limited such activities, and Sheinbaum has amended the Constitution to require express Mexican authorization for field operations. Pérez Ricart observed that without clear rules, these actions often occur without federal knowledge, potentially leading to abuses. A federal judge is expected to rule Saturday on whether the treason indictment will be allowed to proceed.

The outcome of the trial will likely define the boundaries of future cooperation between Mexico and the United States. While the operation itself was a significant success in targeting drug production infrastructure, the human cost and the procedural disputes have turned a law enforcement victory into a constitutional crisis. The case remains under close observation by both governments as they navigate the delicate balance between joint security efforts and domestic sovereignty.
