Mexico's government is tracking 17 deaths of Mexican nationals during ICE operations or in custody and has filed 20 complaints with U.S. state and district prosecutors across eight states, though only four have received responses. Among the cases is 19-year-old Royer Pérez, arrested in January by police in Volusia County, Florida on identity theft allegations and later found dead in a state detention facility; officials initially ruled the death a suicide, but testimony from other detainees and a preliminary medical examiner report suggest he was killed by guards, and Florida authorities declined further investigation. At least four other deaths occurred at the Adelanto detention center in California, operated by GEO Group, with families and civil society groups alleging negligence, mistreatment, and inadequate medical care. Mexican President Claudia Sheinbaum has called for investigations into ICE personnel and private contractors, stating 'there are simply too many cases,' and Mexico has notified the U.N. Human Rights Council, allocated funds for repatriation of remains, filed a complaint with the U.S. Department of Justice, and is pursuing litigation tied to the Adelanto deaths.
