A São Paulo Justice Court converted the detention of Breno de Souza Castro to preventive custody after he confessed to killing his two daughters [1, 2, 4].

The ruling ensures the suspect remains imprisoned while investigators determine the full circumstances of the crime, which involved the deaths of two young children.

Authorities discovered the bodies of the girls, ages three and five [1], inside a vehicle on Rua Luiz Supertti in the Jardim Guanabara neighborhood of Zona Sul, São Paulo [1, 5]. The discovery occurred on Sunday, Aug. 9, 2024, which coincided with Father's Day [1, 2].

Following the incident, Castro presented himself to the 48º Distrito Policial in Cidade Dutra [1, 5]. During a custody hearing held on Monday, Aug. 10, 2024, he confessed to the killings [1, 2].

Police reports indicate a history of domestic volatility. According to statements, Castro had previously threatened and assaulted the mother of the children [2, 3]. Reports on the cause of death vary between suffocation and asphyxiation [2, 3].

Castro is 24 years old [1, 2, 3]. The court's decision to maintain his detention prevents his release on bail or house arrest while the legal process continues.

A São Paulo Justice Court converted the detention of Breno de Souza Castro to preventive custody.

This case highlights the intersection of domestic violence and filicide, where previous aggression toward a partner often serves as a precursor to violence against children. The court's decision to implement preventive custody reflects the high risk associated with the suspect's history of threats and the gravity of the confessed crimes.
