Nicaragua’s government confirmed on Sunday that Brooklyn Rivera, a prominent Indigenous leader and activist, has died at age 73 while in state custody. The government attributed his death to a bacterial infection that developed following a bout of COVID-19. The announcement followed intense pressure from international rights advocates and the United States, who had expressed grave concerns for Rivera’s welfare.

Rivera, a member of the Miskito Indigenous group, had been detained by Nicaraguan authorities since September 2023. For nearly three years, he was held incommunicado, with his family barred from visiting him and his imprisonment initially unconfirmed. This prolonged isolation and lack of contact led advocates to fear for his life and well-being.

The government released photographs on May 27 showing Rivera emaciated and intubated in a hospital bed. His condition was described as “delicate,” suffering from “multiple organ failure, a cirrhotic liver and an active lung infection.” He was reportedly receiving treatment with mechanical ventilation and intravenous feeding.

Critics and human rights experts have voiced skepticism regarding the government's explanation for Rivera's death. Reed Brody, associated with the United Nations Group of Human Rights Experts on Nicaragua, stated that if Rivera is dead, the cause cannot be attributed solely to illness. Brody asserted that the true cause lies in his prolonged detention under conditions of enforced disappearance and denial of independent medical oversight.

The United States government responded to the news by demanding Rivera's "unconditional release" and blaming Nicaraguan leaders for his "cruel treatment." A statement from the U.S. State Department condemned the "repression, violence, and inhumanity" and reiterated calls for the release of Rivera and all other political prisoners.

Nicaragua has been under increasing international scrutiny for its human rights record under the administration of President Daniel Ortega and Vice President Rosario Murillo. Dissidents and critics of the government have frequently faced arrest, imprisonment, and other forms of persecution. Rivera, who had spoken out against Ortega's government, was a vocal advocate for the protection of Indigenous ancestral lands along the country's northeast coast, an area facing pressure from external interests.

Rivera’s death brings renewed attention to the plight of Indigenous communities in Nicaragua and the broader crackdown on dissent within the country. His advocacy for land rights and his political activism placed him in opposition to the government, ultimately leading to his lengthy detention.

Questions remain about the full circumstances of Rivera's detention and the medical care he received. The government's delayed confirmation and the release of images showing his critical state have fueled demands for greater transparency and accountability regarding the treatment of political detainees in Nicaragua.
