Man Arrested in Conceição de Macabu Over 'Chumbinho' Poisoning Plot

Overview

• The arrest took place Sunday, May 31, after Deam and Polícia Civil agents found the 45‑year‑old suspect working at a gas station in the Paraíso neighborhood of Conceição de Macabu.
• Investigators had earlier located and detained the couple’s 18‑year‑old daughter at home and say she assisted in planning the attacks despite first reporting her mother’s hospitalization.
• Police say the victim, a 59‑year‑old woman, was poisoned on two occasions in October 2025 — once with 'chumbinho' placed in a hot dog and later with poison hidden inside a capsule of her regular medication — and required hospital care.
• Authorities attribute a financial motive to the plot, saying the alleged goal was to collect a life‑insurance policy that named the children as beneficiaries and that investigators found related financial activity.
• The suspect will remain at the disposal of the justice system under a preventive warrant from the 4ª Vara Criminal of São Gonçalo while the Deam and Polícia Civil continue probing the case and related gender‑based violence in the city.
