Cintia Mariano Dias Cabral was convicted by the 3rd Court of Jury in Rio de Janeiro for the crimes of qualified homicide and attempted homicide against her stepchildren, stemming from a case in 2022 where she allegedly poisoned them with chumbinho, a type of rodenticide. The jury deliberated for almost 16 hours before delivering their verdict, which resulted in a sentence of 49 years and six months imprisonment. The judge particularly highlighted the severe and disastrous consequences of Cintia's actions during the reading of the sentence.

The trial began on the afternoon of Wednesday, October 4, and extended into the early morning of Thursday, October 5. The prosecution's case was built on accusations that Cintia had poisoned the food served to her stepchildren at various times. The first witness, Bruno, who was 16 at the time and survived the poisoning attempt, provided a critical testimony, which helped to affirm the charges against Cintia. This case attracted significant media attention, reflecting on familial abuse and the grim consequences of such acts.

Cintia Mariano's case is not only a significant legal matter as it involves severe charges, but it also raises broader societal concerns about family dynamics and child protection. The outcome of this trial offers a grim reminder of the potential violence that can occur within families, prompting discussions about legal protections for vulnerable individuals and the need for societal vigilance in addressing family-related abuses. Overall, the conviction marks an essential step in delivering justice in a case that shocked many in Brazil.
