Newly released body camera footage from the Military Police reveals Lieutenant Colonel Geraldo Leite Rosa Neto moving about freely in his apartment just after the death of his wife, soldier Gisele Alves Santana, in São Paulo. In the video, aired by Fantástico on TV Globo, the officer can be seen inside the apartment as police teams arrive, walking through various rooms while the situation is still unfolding. He repeatedly asserts that his wife "took her own life" and is seen not adhering to crime scene protocols, which raises suspicions about his involvement.

According to the investigation, it is suggested that Neto may have compromised the integrity of the crime scene on February 18. His actions, including entering and exiting different areas of the apartment where the victim was found, appear to contradict standard procedures that should have been followed to preserve evidence. This has led investigators to scrutinize his behavior, especially given the nature of the circumstances surrounding his wife's death.

During the incident, Neto states multiple times that his wife committed suicide after a domestic dispute, claiming he attempted to end their marriage. He expresses personal concerns, notedly insisting he needs to wash himself, which raises more red flags about his emotional state and behavior post-event. As the investigation proceeds, his narrative and the contradicting evidence from the footage will be critical in determining the nature of Santana's death and whether foul play was involved.
