The Supreme Federal Court (STF) of Brazil is set to commence the trial of several accused individuals linked to the assassination of councilwoman Marielle Franco, beginning on Tuesday, April 24. Key figures in this case include former deputy Chiquinho Brazão, his brother Domingos Brazão—a councilor at the Rio de Janeiro State Court of Accounts (TCE-RJ)—and former civil police chief Rivaldo Barbosa. These accused individuals have been in custody since March 2024 and are alleged to have orchestrated the planning of Franco's murder, which they deny. Additionally, two police officers are facing charges for allegedly assisting in the crime's preparation.

Beyond the murder conspiracy, the Brazão brothers are also accused of leading a criminal organization involved in territory control and land grabbing in West Rio de Janeiro. The trial's proceedings are particularly significant as it takes place in the Supreme Court due to the timing of the crime—during Chiquinho Brazão's tenure as a federal deputy. The court has allocated two days for the trial, with hearings beginning at 9 am on Tuesday and expected to conclude by Wednesday, April 25. This legal process is closely monitored and carries implications for accountability in violence against political figures in Brazil, particularly in cases involving organized crime.
