Diego dos Santos Ribeiro was 36 years old and registered as CAC. According to the Civil Police, he used a friend's gun, which was not registered.
The corporation also said that the gun was not registered and that the victim's friend has several stints with the police, so he could not, in theory, have CAC registration. However, investigations are still ongoing.
Diego even received first aid from the Fire Department, but did not resist and died still in the shooting range. The Civil Police has already requested expertise at the scene and is analyzing images from the crime scene.
