Overview
- Federal judge María Servini closed the instruction phase and on May 12 advanced the portion of the case against gendarme Héctor Jesús Guerrero to an oral trial.
- Prosecutors and judicial peritajes say Guerrero fired six horizontal gas‑projectile shots between 17:05 and 17:25 from the intersection of Avenida Hipólito Yrigoyen and Solís toward demonstrators.
- Human‑rights lawyers from CELS and the Liga Argentina por los Derechos Humanos asked that Guerrero be tried for attempted aggravated homicide and aggravated weapons abuse.
- Photographer Pablo Grillo, who was nearly killed when a gas canister struck his head on March 12, 2025, continues medical recovery with lasting sequelae and met former president Cristina Kirchner at a Lanús event on May 24.
- The oral trial and the judge’s order to extract further testimonies to probe the chain of command could increase public scrutiny of Gendarmería’s crowd‑control rules and shape future oversight of security forces during protests.
