Mexico will request that U.S. authorities pursue criminal charges for 17 Mexican nationals who died in immigration custody or during enforcement actions, officials said Thursday. The non-binding petition goes to state prosecutors and the Justice Department; civil suits will target detention center firms. President Claudia Sheinbaum said her government escalated beyond standard diplomacy after an ICE agent killed Lorenzo Salgado Araujo in Houston this week, a death she called seemingly deliberate. Homeland Security stated the victim, an unauthorized resident, was fatally shot when he disobeyed orders and tried to hit the agent, who fired in self-defense. The move worsens already tense relations as the countries negotiate a trade deal and cooperate on security.
