Washington Shielded Antonio Lozano to Protect Border Task Forces

By Desmond Okafor · August 16, 2026

A suspected assassin walked free in 1996 while Washington shielded Mexico's Attorney General to prevent the collapse of vetted investigative units and border task forces.

Luis Donaldo Colosio was murdered in 1994, a political hit that fractured the Mexican state and left a nation searching for the truth behind the trigger. When Othon Cortes—the man alleged to be the "second gunman" in that assassination—was released from custody, the public outcry was immediate, but Washington saw a different set of priorities.

"Uncorrupt, serious, and dedicated"

The file's catalogue entry records a confidential cable sent from the U.S. Embassy in Mexico on August 8, 1996. In it, Ambassador Jones describes Mexico’s Attorney General, Antonio Lozano, in glowing terms. Despite the public firestorm following the release of Cortes, Jones reported that Lozano "continues to appear uncorrupt, serious, and dedicated to expanding cooperation with the USG in law enforcement matters."

It is a familiar script: a Washington diplomat vouching for a foreign official whose domestic legitimacy is crumbling. While the Mexican public questioned why a prime suspect in a presidential candidate's murder was walking free, the U.S. Embassy was more concerned with Lozano's willingness to play ball with American interests. In the eyes of the embassy, "seriousness" was not defined by the ability to solve a high-profile political murder, but by the ability to maintain a smooth working relationship with the United States.

Border task forces and vetted units

The cable makes the stakes of this support explicit. Washington was not backing Lozano out of a belief in his judicial brilliance or a desire for Mexican legal transparency, but because he represented a stable point of contact for U.S. security interests. According to the catalogue entry, the U.S. government feared that any change in the leadership of the PGR (Procuraduría General de la República) would "stop any chance of such reform for the moment."

More importantly, the Embassy warned that a change in leadership would "threaten important bilateral cooperation such as the border task forces and vetted investigative units."

This is where the priorities shift from justice for a murdered politician to the maintenance of a paramilitary security apparatus. The "vetted units" and "task forces" were the real currency of the relationship. These units, often operating with a degree of separation from traditional judicial oversight, provided the U.S. with a streamlined channel for law enforcement and intelligence gathering. The release of a suspected assassin was a domestic crisis for Mexico, but for Ambassador Jones, it was a secondary concern compared to the risk of disrupting the pipeline of cooperation.

The document records a conversation between Lozano and Jones in which the Attorney General indicated he would appeal the release of Cortes. This suggests a performative commitment to justice—a gesture of "seriousness" intended to satisfy the embassy and the public—even as the workings of the state had already permitted the suspect to go free.

When the U.S. government speaks of "reform" in the context of a foreign police force, it rarely means the establishment of accountability or the protection of human rights. In this cable, "reform" is tethered directly to the continuity of the PGR's leadership. The U.S. did not want a reformed Mexican judiciary that might uncover inconvenient truths about the Colosio assassination; it wanted a reliable partner who could keep the border units running without interruption.

The catalogue entry notes that the cable spans seven pages, though the full text of those pages remains separate from the summary. What survives in the record is a clear hierarchy of needs. The U.S. government viewed the stability of the PGR as essential to its own security interests, regardless of whether that stability was bought at the cost of the Colosio investigation.

The record leaves the result of Lozano's appeal unanswered, but it confirms that for the U.S. Embassy, the "importance of continuity" outweighed the demand for accountability in the death of a presidential candidate.
