Legal Proceedings Intensify Over Unauthorized CIA Operations in Chihuahua

The legal fallout from a fatal accident in Chihuahua, Mexico, has escalated into a significant federal case involving allegations of treason against former state officials. On April 19, 2026, a vehicle belonging to the State Investigation Agency (AEI) plunged into a ravine in the municipality of Batopilas, resulting in the deaths of four individuals: AEI director Pedro Román Oseguera Cervantes, his escort Manuel Méndez Montes, and two U.S. citizens identified as CIA agents Richard Leiter Johnston III and John Dudley Black.

Investigations by the Mexican Attorney General's Office (FGR) revealed that the presence of these foreign agents in Chihuahua was not authorized by the federal government. Evidence collected by federal authorities contradicts initial state government claims that the agents were merely providing informal drone training. Records from the state's security complex, the C4, show a vehicle associated with Johnston III entering the facility on April 14, 2026, with an entry log explicitly referencing a meeting with Guillermo Arturo Zuany Portillo, the former fiscal of Strategic Operations.

The FGR’s findings suggest that the agents were actively involved in an operation to secure clandestine drug laboratories in the El Pinal area. While the Mexican military provided a perimeter shield for the operation, they reported that they were never informed of the presence of foreign personnel. Federal agencies, including the Secretariat of Security and Citizen Protection (SSPC), confirmed that no agreements were signed with the Ministry of Foreign Affairs to permit the deployment or accreditation of these agents within Mexican territory.

In response to these findings, a federal judge issued arrest warrants on October 17, 2026, for former Chihuahua Attorney General César Gustavo Jáuregui Moreno and former Strategic Operations fiscal Guillermo Arturo Zuany Portillo. Both men are being investigated for treason, a charge under the Mexican Federal Penal Code that applies to citizens who perform acts against national sovereignty to subject the country to foreign influence. Jáuregui was arrested following his resignation in April, while Zuany Portillo remains a fugitive.

The case has also drawn scrutiny regarding the handling of evidence. Reports indicate that security camera footage from the fiscal's office was interrupted by power outages during critical periods, and the National Migration Institute reported no official entry records for John Dudley Black. Furthermore, the families of other U.S. personnel have raised concerns about the transparency of state investigations, leading to formal complaints against current state leadership regarding the alleged manipulation of case files.

As the legal proceedings move forward, the case has been transferred to the Federal Center for Criminal Justice in Almoloya de Juárez due to security concerns and the high risk of flight. The incident has sparked a broader debate regarding the limits of international cooperation in security operations and the accountability of state-level officials when engaging with foreign intelligence services without federal oversight.
