Carlos Josué Marchena, a 37-year-old Costa Rican national from Guanacaste, died on September 18, 2026 while in ICE custody at the Winn Correctional Center in Winnfield, Louisiana, after being detained since January. His cousin, Bryan Marchena, said Carlos was diabetic and appeared to have suffered a cardiac problem, and that he was found unconscious after complaining of severe chest pain hours earlier. Family members said his care had been adequate while he was held in Michigan but grew concerned after he was transferred through several facilities, citing inconsistent meal timing and medication management for his diabetes. His sister, Francini Araya Marchena, confirmed his death and said ICE never carried out his planned deportation to Costa Rica. Friends said he had migrated to the U.S. seeking better opportunities for his children, and a GoFundMe campaign has been launched to help bring his body home while the family awaits autopsy results to determine the official cause of death.
