The trial of Cíntia Mariano Dias Cabral, who is accused of poisoning her two stepchildren with a pesticide known as 'chumbinho', commenced at the III Tribunal do Júri in Rio de Janeiro. The first witness to testify was Bruno Carvalho Cabral, the surviving victim, who recounted the distressing experience of feeling ill after a meal at his stepmother's home. During his testimony, Bruno described noticing an unusual taste and seeing 'many blue dots' in the beans, indicating the potential presence of the toxic substance.

Bruno's emotional testimony was a poignant reminder of the tragedy, especially as he spoke about his late sister, Fernanda Cabral, who died under similar circumstances. His account detailed that the meal that altered the course of their lives occurred after a school simulation event, where a casual lunch turned into a harrowing experience. The courtroom was filled with emotional tension as Bruno reflected on the irreversible loss of his sister, underscoring the case's gravity.

Cíntia's trial not only seeks justice for the victims but also reignites discussions regarding domestic safety and the vulnerabilities children face in their own homes. As the trial progresses, it raises essential questions about the responsibilities of guardians and potential legal reforms needed to protect children from similar situations in the future.
