Dive into one of Brazil's most horrifying true crime cases, the Piaui family poisoning, which transformed a joyous New Year's Day lunch in 2025 into an unimaginable nightmare. In the tranquil coastal city of Parnaiba, a traditional rice and bean dish, meant to symbolise prosperity for the year ahead, was insidiously laced with a deadly pesticide. This calculated act claimed the lives of eight family members, including six children, across two separate incidents of poisoning.
Discover the chilling truth behind the earlier, mysterious deaths of seven-year-old Joao Miguel and eight-year-old Ulisses Gabriel in August 2024, which were initially blamed on an innocent neighbour. These fatalities were, in fact, an opening chapter and "practice run" orchestrated by those closest to them. Uncover how Francisco de Assis Pereira da Costa, the children's stepfather, harboured deep and pathological resentment, referring to them as "primates" and "country bumpkins".
The case takes an even more sinister turn with the shocking confession of Maria dos Aflitos da Silva, the family matriarch and grandmother of several victims. She not only participated in the New Year's Day poisoning but also murdered a neighbour, Maria Jocilene, in a twisted attempt to frame her and protect Francisco from suspicion. This harrowing account exposes the devastating effects of domestic violence, profound family betrayal, and the terrifying reality of shared psychosis.
We delve into the meticulous police investigation led by Detective Abimael Silva, the crucial forensic analysis that confirmed terbufos, a highly toxic and domestically banned organophosphate pesticide, as the weapon. The story also highlights the tragic irony of Lucelia Maria da Conceicao Silva, the innocent neighbour who spent five months wrongfully imprisoned. Furthermore, we examine the broader context of pesticide crime in Brazil, where permissive regulations contribute to deadly substances like "chumbinho" becoming instruments of family violence.
"Piaui family poisoning: A New Year's Day massacre" is a powerful and unsettling exploration of how hatred can fester within a home, turning protectors into predators and leaving a community grappling with unimaginable loss. It poses the haunting question: could this tragedy have been prevented if the warning signs had been recognised and acted upon?
