Roger da Motta Carvalho, a municipal guard, is set to go on trial in Porto Alegre for the murder of Bruno Saraiva Salgado, a 30-year-old real estate broker, as well as for injuring the victim's dog, Otto, which survived the shooting. The incident occurred on December 8, 2016, during a confrontation between the two men over the victim's dog in their condominium in the South Zone of Porto Alegre.

According to the state Public Ministry's indictment, Carvalho was off-duty when he got into an argument with Salgado while the latter was walking his Labrador Retriever. In an escalation of the dispute, Carvalho returned to his home, retrieved his firearm, and shot Salgado twice in the torso. The attack not only resulted in the tragic death of Salgado, but also left his pet injured, sparking public concern and outrage regarding animal cruelty and the responsibilities of firearm owners.

The trial has broader implications for community safety, as it addresses issues of violence in interactions between neighbors and the treatment of animals in such disputes. The accused is facing charges of simple homicide and animal cruelty, highlighting the legal frameworks governing these issues in Brazil, and exposing society's ongoing struggles with violence, both human and animal, in domestic environments.
