The Federal Public Ministry (MPF) in Amazonas has taken decisive action to continue investigating the murder of Maxciel Pereira dos Santos, an employee of the National Foundation of Indigenous Peoples (Funai), who was killed in September 2019 in Tabatinga, Amazonas, near the Colombian border. This decision came after the Federal Police (PF) suggested archiving the case due to insufficient evidence, but the MPF disagreed, highlighting the need for further investigative steps to resolve the case that remains unsolved over six years later. Among the actions ordered by the MPF is a request for testimony from Ruben Dario Villar, who is already a defendant in another case involving the murders of indigenous rights activist Bruno Pereira and journalist Dom Phillips in 2022. Villar's potential insights could shed light on interconnected cases of violence against those advocating for indigenous rights and environmental protection in the Amazon region. The ongoing investigations underscore the challenges faced by law enforcement in addressing crimes against indigenous peoples' rights and the lingering impacts of unsolved murders in communities deeply affected by violence and social injustice. The MPF's decision signals a renewed commitment to seek justice for Maxciel's family and to address broader concerns regarding safety and advocacy for indigenous communities in Brazil.
