Rio forensic institute refused prosecutors the autopsy reports from the 2025 police raid that left 122 dead, and federal prosecutors asked the Supreme Court to intervene

After the 28 October 2025 police operation in Rio's Alemão and Penha complexes, in which 122 people died (117 civilians and five officers by later counts), Human Rights Watch reported that crime scenes were not preserved or forensically analysed. In April 2026 Brazil's federal prosecutor-general's office asked the Supreme Court to compel Rio's medical-legal institute to hand prosecutors the necropsy protocols and photographs, which it had declined to provide.
