A police detention of a teenage girl occurred due to allegations of poisoning food intended for her parents and cousin. The incident, linked to a ban on her seeing a boyfriend, involved the addition of a toxic substance named chumbinho to meals prepared by her mother in Nova Serrana, Minas Gerais, Brazil, on January 7. The 17-year-old admitted to the act, which followed a disagreement with her parents. The substance, typically used for killing rodents, was found in the meals. The cousin detected the alteration in the food’s texture and avoided consuming it. Medical attention was sought, and the cousin remains stable. The girl’s actions were reportedly driven by anger over her parents’ disapproval of her romantic relationship. Samples were collected for laboratory analysis, and the case is under investigation. The teenager is in police custody and awaiting legal proceedings. In a separate case in Australia, a woman received a lengthy prison sentence for poisoning family members with death cap mushrooms.
