Overview

• São Paulo’s forensic lab confirmed terbufós, an agricultural insecticide associated with “chumbinho,” in a glass vial seized from Ana Paula Veloso Fernandes’s residence.
• Police say at least three bodies have been exhumed and toxicology is pending to determine whether the same poison was used in four deaths across São Paulo and Rio.
• Authorities describe a recurring pattern that includes the suspect remaining near crime scenes, using false identities, and alleged schemes such as a faked pregnancy and an effort to frame a former partner.
• Parts of the suspect’s account of her landlord’s death are contradicted by a necropsy and police body‑camera footage, which showed no traumatic injuries or visible blood at the scene.
• Fernandes is in preventive detention and has been made a formal defendant; her twin, Roberta, is being heard today as an alleged accomplice, and Michelle Paiva da Silva is jailed over the killing of her father.
