Luis Muñoz Pinto, a 27-year-old Venezuelan who had been studying robotics engineering, was detained during a scheduled Customs and Border Protection appointment under the CBP One program and deported to El Salvador's CECOT prison in March 2025. U.S. officials cited rose tattoos, which he says represent his twin sisters, as evidence linking him to the Tren de Aragua gang, an accusation he denies, and he had no criminal record in the United States. He said conditions at the prison included lights kept on 24/7 and withheld food, medicine, and drinking water. He was released in July 2025 and returned to Colombia. A federal court later ruled that Muñoz Pinto and more than 100 other deported Venezuelans must be allowed to return to the U.S. for due process, and he hopes to clear his name and resume his studies.
