Five-Year-Old Girl Accidentally Shoots and Kills Her Three-Year-Old Sister After Finding Loaded Pistol at Home

A heartbreaking tragedy unfolded in Rio de Janeiro, Brazil, after a three-year-old girl was fatally shot by her five-year-old sister, who reportedly discovered their father’s loaded 9mm pistol inside the family home. The victim, identified as Olivia Melo Moreira, died on November 8, 2026, after the gun discharged during the incident.

According to the father’s statement to police, he had taken the holstered firearm downstairs after noticing that the property’s garage gate was open. He reportedly left the loaded weapon on the kitchen counter before returning to bed. The family later woke after hearing a loud noise and discovered Olivia seriously injured. Her parents rushed her to hospital, but doctors were unable to save her.

Investigators believe the older sister found the pistol and accidentally fired it, striking the younger child. The circumstances surrounding how the five-year-old accessed the weapon are now central to the investigation. Police seized the firearm and carried out forensic examinations at the property to establish exactly what happened.

The father reportedly held legal authorization to possess firearms as a registered collector, sport shooter and hunter. However, authorities are examining whether he failed to secure the weapon properly and allowed a child to gain access to it. He voluntarily gave a statement to investigators and had not been arrested at the time of the report.

Police are considering proceedings against the father over suspected involuntary manslaughter and failure to take appropriate precautions to prevent his daughter from accessing the gun. Investigators have not ruled out the possibility of a more serious charge, depending on the evidence gathered. The five-year-old child, meanwhile, is not being treated as a criminal suspect.

The devastating incident has renewed concerns about firearm safety in homes where young children are present. A weapon that should have been securely stored was allegedly left within reach, with consequences that cannot be undone. As investigators continue examining the evidence, Olivia’s family is left grieving the loss of a little girl whose life ended in a tragic household accident.
