Sheinbaum hardens stance after Mexican detainee dies in ICE custody

Mexico is hardening its public stance after Alejandro Cabrera Clemente, a 49-year-old Mexican citizen, died in ICE custody at the Winn Correctional Center in Louisiana, turning detention conditions into a new test of U.S.-Mexico cooperation.

ICE said Cabrera Clemente was found unresponsive on April 11 and later pronounced dead after being taken to a local medical center. The agency said he was a Mexican national with prior convictions for disorderly conduct, drug possession and probation violation, along with an arrest for domestic violence. His death was the 47th in ICE custody during the second Trump administration, and at least 15 Mexican nationals have died in ICE custody or during immigration enforcement actions since 2025.

Claudia Sheinbaum responded by ordering Mexican consulates to visit detention centers daily and requesting investigations into the deaths of 15 migrants. She said Mexico would take the matter to the Inter-American Commission on Human Rights and was considering an appeal to the United Nations. “We are going to defend Mexicans at every level,” she said, adding that many migrants’ only “crime” is not having papers.

The Mexican government has called the deaths in custody unacceptable and said ICE detention centers are incompatible with human-rights standards and the protection of life. The pressure intensified after another Mexican migrant, José Guadalupe Ramos, died in ICE custody in Los Angeles on March 25 at the Adelanto ICE Processing Center, helping drive Mexico’s push for daily inspections and international complaints.

The tougher tone marks a shift in a relationship Sheinbaum had kept carefully managed for more than a year. She previously balanced public restraint with cooperation on cartel enforcement, seeking to blunt tariff threats and the risk of U.S. military action against Mexican gangs. Now the dispute has widened further, with the Trump administration’s Cuba policy, including an energy blockade that Mexico opposes, adding another point of friction. Mexico also said on March 25 that it would keep its agreement with Havana to use Cuban doctors despite U.S. pressure.

For Sheinbaum, the deaths in custody are no longer just a migration issue. They have become a measure of whether the bilateral relationship can absorb the political fallout of repeated deaths in detention without spilling into a broader rupture.
