An investigation led to the arrest of Lieutenant Colonel Geraldo Leite Rosa Neto following the death of police officer Gisele Alves Santana. The military justice system found substantial evidence, including forensic reports that contradicted the initial claims about the incident. It was concluded that Gisele was attacked from behind, with the assailant covering her mouth before firing a gun owned by the lieutenant colonel, raising serious concerns about the circumstances of her death.

The detailed findings emerged from examinations conducted by the Técnico-Científica Police, which highlighted evidence suggesting that Gisele could not have shot herself. This aspect of the case played a crucial role in the military court's decision to arrest Rosa Neto, with the judge citing inconsistencies in testimony provided by the victim's husband as further support for the allegations. The observations of the crime scene and blood patterns have been pivotal in establishing the narrative of aggression.

This incident has sparked significant public interest and concern regarding domestic violence within the police force, shedding light on the darker side of law enforcement. As the investigation proceeds, the implications of this case could lead to broader discussions on accountability and the treatment of gender-based violence, especially in institutions traditionally dominated by male figures.
