Mexico Collaborates with U.S. Counties in Death Investigations

The Mexican government announced Wednesday its cooperative effort with three United States counties to investigate the deaths of 17 Mexican citizens associated with U.S. Immigration and Customs Enforcement (ICE) activities. These deaths occurred either while in ICE custody or during operations. Mexican Secretary of Foreign Affairs, Roberto Velasco Álvarez, stated alongside President Claudia Sheinbaum that legal and diplomatic measures have been taken due to these fatalities during Donald Trump’s second term. He emphasized that each case involves a Mexican family seeking truth and justice.

To advance investigations, Velasco Álvarez shared that Ventura County, California, Cook County, Illinois, and Harris County, Texas, have agreed to collaborate on cases relevant to their jurisdictions. A recent event in Harris County involved the shooting and killing of Mexican national Lorenzo Salgado Araujo by an ICE agent while he was in his work van in Houston. Similarly, Jaime Alanís García fell to his death from a greenhouse during an ICE operation in Ventura County in July 2025.

Tension has escalated between Mexico and the U.S. as additional reports of ICE-related deaths emerge. President Sheinbaum has expressed deep concern over these fatalities. She highlighted the rarity of U.S. state and local authorities addressing international diplomatic issues, traditionally handled by the federal government.

The Cook County State’s Attorney’s Office confirmed communication with Mexican officials. Harris County District Attorney’s Office also acknowledged discussions with Mexican authorities. Meanwhile, a response from Ventura County was pending by publication time.

Investigating the 17 Deaths

Mexico has consistently pointed to 17 fatalities involving its nationals, with Velasco Álvarez noting that 14 incidents occurred within immigration detention facilities or following medical treatment, while three happened during immigration enforcement operations.

The featured cases from the counties involve deaths already attracting considerable media and political attention. In Ventura County, California, farmworker Jaime Alanís García suffered fatal injuries from a greenhouse fall during a major immigration raid at Glass House Farms in Camarillo in July 2025. His death spurred debates on workplace enforcement tactics. Federal authorities contended that García was not in ICE custody when he fell.

In Cook County, Illinois, Mexican national Silverio Villegas González was fatally shot by an ICE agent during a Franklin Park traffic stop in 2025. DHS reported González attempted to flee and dragged an officer with his vehicle. Body-camera footage later raised doubts about the officer’s injuries, prompting the Cook County State’s Attorney’s Office to engage with Illinois State Police in investigating the death.

For Harris County, Texas, 52-year-old Lorenzo Salgado Araujo was shot by an ICE officer during a Houston operation in July. DHS admitted Salgado Araujo was not initially targeted, though agents thought he resembled their suspect. The Harris County medical examiner ruled the death as a homicide, with local prosecutors investigating independently.

County Attorney Abbie Kamin praised DA Sean Teare’s leadership in pursuing transparency and accountability during the investigation. She emphasized the close collaboration with Mexican officials to ensure justice and safety.

Diplomatic Friction

The deaths have stirred diplomatic tension between Washington and Mexico City. President Sheinbaum condemned these fatalities, demanding accountability and stressing against Mexico’s silence when citizens die amid enforcement actions or while detained in ICE-contracted facilities. Mexican officials declared intentions for criminal investigations in U.S. jurisdictions, civil actions against detention contractors, and engagement with international human rights entities.

The Trump administration rejected claims of systematic abuse, asserting detainees received medical care and due process. DHS denied misconduct allegations among enforcement personnel.

México’s criticism simultaneously contrasts with cooperation on migration enforcement, reflecting diplomatic balance. Mexican officials reiterated their concerns pertaining to detention centers’ conditions without seeking conflict with the United States, prioritizing human rights protection for compatriots.

In response, DHS stated to Newsweek, “There has been NO spike in deaths. Consistent with data over the last decade, death rates in custody under the Trump administration are 0.008% of the detained population.”

County Reviews Importance

The announcement shifts focus beyond federal oversight, emphasizing the inclusion of county-level involvement. ICE officers, being federal personnel, typically encounter investigations within federal review systems. Critics argue local prosecutors often lack scrutiny equivalent to local law enforcement’s shootings.

Independent reviews, records requests, or state investigator coordination from Ventura, Cook, and Harris counties may enable Mexican efforts to explore scrutiny aside from federal immigration oversight.

In Harris County, prosecutors have pursued an independent review of the Salgado Araujo shooting, diverging from standard internal federal investigations. Illinois witnessed activist-led calls for greater accountability following Villegas González’s death. The broader question remains if Mexico’s involvement might spur additional local authority actions otherwise unlikely to happen.

International Pressure on the Rise

Mexico’s efforts extend beyond U.S. courts. The update mentions the involvement of the United Nations High Commission for Human Rights office, which expressed concern and urged prompt investigations along with victims’ rights protection.

This international involvement may pressurize U.S. officials, although decisions on prosecutions or investigations rest with American authorities. Regardless of whether county reviews culminate in criminal outcomes, civil lawsuits, or no actions, Mexico’s strategy elevates foreign government’s response to its nationals dying amid U.S. enforcement.

For Sheinbaum’s administration, the aim appears to transform isolated incidents into broader accountability examination related to Trump’s immigration policy.
