Law enforcement authorities in Paraná have carried out targeted operations following the daylight execution of a suspect linked to prior violent incidents in the Metropolitan Region of Curitiba.

Authorities from the Civil Police of Paraná launched specialized operational actions following a fatal shooting recorded on February 23, 2026, in the municipality of Fazenda Rio Grande, located within the Metropolitan Region of Curitiba, Brazil. Official police documentation indicates that the victim, identified as 33-year-old Willian Rafael Nonato, was intercepted outside his residence on Rua Quaresmeira, in the Eucaliptos neighborhood.

According to investigative records and security camera footage gathered by law enforcement, Nonato was inside a stationary vehicle alongside his wife when another automobile approached. Upon attempting to flee on foot, he was struck by the vehicle and subsequently shot multiple times with a 9 mm caliber handgun by three armed individuals. Emergency responders confirmed his death at the scene, while his spouse escaped without physical injury. Hours after the event, officers located the getaway vehicle partially burned near a bridge over the Iguaçu River.

The investigation conducted by the Civil Police of Paraná formally connected this homicide to an armed assault reported on November 2, 2025, in the Campo de Santana neighborhood of Curitiba. Official reports state that during that event, multiple rounds were fired at an assembly, resulting in injuries to four individuals. Among the victims was 56-year-old Sandra Aparecida de Oliveira Pinto, who succumbed to her injuries on January 22, 2026. Nonato had been taken into custody by authorities on January 25, 2026, in connection to those events, but was later released prior to the February incident.

By May 2026, law enforcement agencies executed Operation Janus, an investigative framework targeted at resolving the case. Police actions led to the arrest of a 31-year-old suspect on April 30 in the Alto Boqueirão area of Curitiba. Subsequently, on May 18, 2026, preventive arrest warrants were served against two additional suspects, aged 23 and 28, who were already in custody for separate offenses. Judicial proceedings coordinated by regional authorities remain active.
