Mexican government launches investigation into deaths of 17 citizens during U.S. ICE enforcement operations or detainment
Mexico‘s government has opened investigations into the deaths of 17 Mexican citizens who died in U.S. Immigration and Customs Enforcement custody or during ICE operations, Mexican Secretary of Foreign Affairs Roberto Velasco Álvarez announced August 19 alongside President Claudia Sheinbaum.
Velasco Álvarez said “legal and diplomatic actions” were underway and that officials in Ventura County, California; Cook County, Illinois; and Harris County, Texas, had agreed to cooperate with Mexico on cases within their jurisdictions.
“Each case has behind it a Mexican family that deserves truth and justice,” Velasco Álvarez wrote on X.
Of the 17 deaths, 14 occurred in immigration detention facilities or after detainees were transferred for medical treatment, while three occurred during enforcement operations.
The county-level cases driving the effort
The three deaths tied to the counties have each drawn significant attention.
In Ventura County, farmworker Jaime Alanís García died after falling from a greenhouse during a large-scale immigration raid at Glass House Farms in Camarillo, California. Federal authorities have said he was not in ICE custody when he fell.
In Cook County, Mexican national Silverio Villegas González was fatally shot by an ICE agent during a traffic stop in suburban Franklin Park, Illinois, in 2025. The Department of Homeland Security said Villegas González attempted to flee and dragged an officer with his vehicle. Body-camera footage later drew scrutiny over the officer’s reported injuries.
A spokesperson for the Cook County State’s Attorney’s Office told Newsweek the office is “committed to supporting the Illinois State Police investigation” and “will not hesitate to bring criminal charges against any law enforcement officer, including federal agents, when the evidence and the law support it.” The office also said it was “in touch with the embassy to explain our role in the criminal justice process.”
In Harris County, 52-year-old Lorenzo Salgado Araujo was shot and killed by an ICE officer during an enforcement operation in Houston on July 7, 2026. DHS later said Salgado Araujo did not appear to be the operation’s original target and instead resembled the person agents were seeking.
The Harris County medical examiner ruled the death a homicide, prompting an independent investigation by District Attorney Sean Teare.
Harris County Attorney Abbie Kamin said she was “supporting efforts to bring transparency, answers and accountability,” adding, “I am grateful to DA Teare for his leadership and partnership to ensure justice and accountability in the midst of this tragedy.”
Teare’s office told Newsweek it had spoken with Mexican officials.
Washington’s response
DHS has rejected suggestions of a broader pattern of abuse.
A department spokesperson told 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,” adding that the agency has “maintained a higher standard of care than most prisons that hold U.S. citizens — including providing access to proper medical care.”
Why the county-level strategy matters
Because ICE officers are federal personnel, investigations into their conduct have traditionally remained under federal oversight. Local prosecutors have rarely scrutinized immigration-enforcement incidents with the same intensity applied to shootings involving local police.
By securing cooperation from authorities in Ventura, Cook and Harris counties, Mexico is seeking to bring local scrutiny to deaths involving its citizens outside the federal system.
The strategy is an unusual step for a foreign government responding to enforcement-related deaths of its nationals on U.S. soil. The United Nations’ Office of the High Commissioner for Human Rights has also weighed in, with High Commissioner Volker Türk calling for prompt investigations and protections for victims’ human rights.
