A Mexican state judge on Thursday 22 October 2026 let prosecutors continue one charge against former Chihuahua attorney general César Jáuregui in the CIA raid case and found too little evidence for a second. The ruling comes a week after President Donald Trump said US action against cartels “on land” is “starting”.
For US readers the case shows how far Mexico will police the work of American agents on its soil. President Claudia Sheinbaum has said foreign agents may join ground operations only within the law, and said on Thursday 22 October that the two Americans had no permit for the operation and, as later became known, “were carrying weapons”, in Ámbito’s report of her remarks, translated here from Spanish.
A column in Vanguardia on Friday 23 October by Raymundo Riva Palacio argues that the April CIA presence shows Trump’s warning is already under way. That is his opinion, and the sources reviewed contain no official announcement of a US ground offensive in Mexico.
Our earlier reports cover the arrest in “Chihuahua Ex-Prosecutor Held Over US Role”, the federal accusation in “Mexico Ex-Prosecutor Faces Up to 40 Years” and the reports in “Reports Name 2 CIA Officers Killed in Mexico”. This report covers what the state judge decided in the CIA raid case and what the sources establish about the US agents.
What the Chihuahua Judge Decided
The control judge found enough evidence to continue the charge of improper exercise of public service under case file 3055/2026, Vanguardia and El Informador reported on 22 October. The judge found no sufficient elements for the second charge, known as coalition of public servants.
The step is called vinculación a proceso, which lets prosecutors keep building a case but is not a finding of guilt. Jáuregui followed the hearing by video link from the Altiplano federal prison, where he is held on the federal case.
La Crónica de Hoy reported that the state case rests on the claim that Jáuregui allowed foreign agents to take part in dismantling a drug lab at El Pinal, work that belongs to federal authorities. His lawyer Héctor Villasana called the decision political and said the defence will appeal.
Villasana argued that nothing shows Jáuregui knew the Americans would join, beyond his post as attorney general and his meetings with the head of the state investigation agency. Jáuregui is presumed innocent on both the state and the federal case.
How the CIA Raid Case Reached This Point
State and army forces dismantled clandestine drug labs near El Pinal, in Morelos municipality in the Sierra Tarahumara, between 17 and 19 April. A vehicle returning from the operation fell into a ravine in the early hours of Sunday 19 April, Excelsior reported at the time.
Four people died: two members of the US Embassy staff, as Ambassador Ronald Johnson described them then, the director of Chihuahua’s state investigation agency and one of its officers. Mexican media later described the two Americans as CIA agents, and the column by Riva Palacio notes that the CIA has made no public statement on them.
State officers arrested Jáuregui on Saturday 17 October on Avenida La Cantera in Chihuahua City. At a state hearing on Sunday 18 October a judge let him stay free on conditions, including surrender of his migration documents, but federal agents detained him within minutes, Vanguardia reported.
Federal Attorney General Ernestina Godoy, who leads the prosecutor’s office FGR, said after the arrest that more than 100 investigative steps showed Jáuregui had allowed foreigners to take part without authorisation. She said that conflicts with the Constitution and the National Security Law, which bars states from taking powers reserved to the federal government, El Financiero reported on 18 October.
A federal judge ordered pretrial detention at the Altiplano prison on 21 October, La Silla Rota reported. A hearing set for 15:00 local time on Saturday 24 October decides whether the treason case formally proceeds.
What Is Established About US Agents
The federal case file, as described by Reforma and relayed by Vanguardia on 20 October, includes a state police officer who says he saw four English-speaking people in tactical gear, carrying weapons and wearing no insignia, at the raid site. Two videos show armed men entering the state investigation agency on 9 and 16 April, and the agency’s access log lists only one entry, for a named visitor, on 14 April.
The Defence Ministry told federal prosecutors that soldiers only provided perimeter security, yet a federal forensic report says state agents and the army found the lab together. These are allegations and findings in prosecution documents, not court rulings.
Sheinbaum has said that state prosecutors have no power to dismantle labs tied to federal crimes, Vanguardia reported on 22 October. She faulted Jáuregui not only for letting foreign agents join a ground operation against the law, but for how it was done, in her words translated from Spanish.
By contrast, the Senate approved in September the entry of 139 US soldiers of the 101st Airborne Division for joint exercises in Chihuahua from 20 to 30 September, El Financiero reported on 15 September. That vote, taken at the president’s request, shows the formal route for US troops to enter Mexico.
Trump’s Ground Warning in Context
At a White House lunch on Thursday 15 October, Trump said US forces have “not yet acted on land with full force, but that is starting”, in El Financiero’s Spanish-language account translated here. He added that cartels “govern Mexico”, that he has told Sheinbaum so, and that Mexico is not capable of acting against them right now.
He tied the remark to the US campaign against suspected drug boats at sea, which critics describe as extrajudicial killing. Mexico’s government insists that any foreign security work on its soil must be authorised and run through federal channels.
No source reviewed links the April CIA presence to a Trump order or to the land action he described. Riva Palacio draws that link in his column, and it remains his argument rather than an established fact.
The Sheinbaum and Campos Dispute
On Friday 23 October Sheinbaum said that at a private meeting on 19 September at Ciudad Juárez airport, Chihuahua Governor Maru Campos blamed the former attorney general, telling her “it was not me, it was the former prosecutor”, El Universal reported. Campos leads Chihuahua for the National Action Party (PAN), the conservative opposition party.
Campos denied that she accused him, and told Grupo Fórmula the president’s team already knew his role, El Universal reported. The two accounts conflict, and neither has been tested in court.
What It Means for You
US agencies and companies that work with Mexican state police now face a federal prosecution that treats unauthorised joint work as a possible crime against national security. Firms with plants or security contracts in Chihuahua, a border state next to Texas and New Mexico, may see closer federal scrutiny of any foreign security role.

What Is Not Known
The federal case file has not been published, so the evidence behind the treason charge cannot be tested, and the judge’s written reasons for the state ruling were not available in the sources reviewed. The CIA has made no public statement on the two dead Americans, the column notes, and no US government comment on the Mexican prosecution appears in the sources reviewed.
It is not known whether the federal court will send the treason charge forward on Saturday 24 October, or whether the defence appeal of the state ruling will succeed. It is also not known whether any US ground operation is under way, because no official source reviewed says so.
