Mexico Demands Criminal Probe into Migrant Deaths in US Custody

Mexico has launched a formal diplomatic and legal offensive against the United States, pressing state attorneys general to initiate criminal inquiries into a surge of migrant fatalities involving federal immigration officers.

The aggressive maneuver, formalized on Tuesday, targets deaths occurring both within detention facilities and during field operations conducted by Immigration and Customs Enforcement (ICE).

It underscores a sharp deterioration in cross-border relations under U.S. President Donald Trump’s second administration.

Seventeen Mexican nationals have died in immigration enforcement scenarios since Trump’s current term began.

Fourteen perished in ICE custody, while three were killed during active agency raids.

The Mexican Foreign Ministry confirmed that parallel demands for criminal probes will be submitted directly to the U.S. Department of Justice.

Washington carries no legal obligation to comply with the foreign requests.

Targeting Corporate Detention Centers

Alongside requests for criminal prosecution, Mexico has initiated a pressure campaign against the operators of American holding facilities.

Diplomatic officials have dispatched formal warnings to specific centers, beginning with the Adelanto facility in California, which has recorded four recent Mexican fatalities.

The foreign ministry demanded that operators “immediately cease the actions or omissions that resulted in these deaths, such as preventing access to prompt and expedited medical care, as well as the application of policies incompatible with medical and penitentiary standards.”

This direct correspondence serves as the groundwork for future litigation. The ministry described the letters as the initial phase toward “the eventual filing of civil lawsuits” against the private contractors managing these sites.

Disputed Houston Fatality

The diplomatic escalation was catalyzed by the recent death of Lorenzo Salgado Araujo. An ICE agent fatally shot the 52-year-old last Tuesday in Houston as he drove a construction crew to a work site.

Salgado Araujo had resided in the United States for 35 years and possessed no criminal record.

His killing triggered local demonstrations and prompted calls for independent oversight from Democratic politicians and surviving family members.

The Department of Homeland Security, which manages ICE operations, provided a contradictory account of the confrontation.

Federal authorities allege Salgado Araujo rammed his vehicle into an agency car, prompting the agent to discharge a weapon in self-defense.

International Arbitration

Mexican President Claudia Sheinbaum has broadened the dispute to the international stage as part of a wider response to Washington's border crackdown.

She previously directed Mexican consulates to maintain continuous contact with detained nationals.

Foreign Minister Roberto Velasco has now escalated the grievance to the United Nations. He formally petitioned Volker Türk, the U.N. high commissioner for human rights, to evaluate the fatalities.

Velasco requested that the U.N. gather intelligence on the ICE custody deaths to assess the “compatibility of these events with international human rights obligations.”

He further pressed Türk to secure a formal opinion and policy recommendations from the U.N. Human Rights Council.
