The Assassination of Marielle Franco and Anderson Gomes

Rio de Janeiro councilwoman Marielle Franco and driver Anderson Pedro Gomes were murdered on March 14, 2018. Franco, a Black bisexual woman from the Maré complex, was a human-rights advocate who criticized police violence and represented communities often excluded from political power. Investigators arrested former police officers Ronnie Lessa and Élcio de Queiroz in 2019; both later admitted roles and were convicted. In February 2026, Brazil's Supreme Federal Court convicted five more defendants, including brothers Domingos and Chiquinho Brazão, in the alleged organization and cover-up of the crime.

Marielle and Anderson

Marielle was a sociologist, councilwoman and advocate for women, Black people, LGBTQ+ communities and favela residents. Anderson was a professional driver and father. A staff member traveling with them survived.

International attention often treated Marielle as the sole public symbol, but Anderson was also a victim of the same attack. Responsible remembrance names both people and avoids converting civic work into a sensational conspiracy story.

From the shooters to alleged organizers

The 2024 jury verdict established the criminal roles of Lessa and Queiroz. Cooperation agreements and federal investigation then contributed to a separate proceeding before the STF involving political figures and a former senior police official.

On February 25, 2026, the STF announced convictions of five defendants. The Brazão brothers received sentences of more than 76 years. The judgment marked a major shift from years in which the identity of alleged organizers remained publicly unresolved.

What “major convictions” means

The archive previously would have described the case as partly solved. After the 2026 judgment, both direct participants and alleged organizers have criminal convictions. That supports a stronger solved classification, while recognizing that appeals and implementation of sentences may continue.

A conviction is not the same as the end of every institutional question. Investigators and courts also examined obstruction, militia influence and failures within public agencies. Democratic accountability includes protecting witnesses, preserving independent institutions and reporting judicial outcomes precisely.
