Overview

• Ana Paula Veloso Fernandes, 36, is in custody alongside her twin sister Roberta and Michelle Paiva da Silva as investigators link four deaths in São Paulo and Rio de Janeiro from January to May 2025.
• Authorities say the victims—Marcelo Hari Fonseca, Maria Aparecida Rodrigues, Neil Corrêa da Silva, and Hayder Mhazres—were allegedly poisoned via a sandwich, cake/coffee, bean stew, and a milkshake.
• Bodycam footage and forensic reports described by O Globo contradict the suspect’s claim of using a knife in the first death, reinforcing police suspicions of poisoning.
• Investigators describe a pattern of manipulation, including being the first to contact police after the deaths and attempts to frame others, while the defense argues evidence remains inconclusive and cites the presumption of innocence.
• Police say Fernandes admitted to two killings and to testing poison on dogs; prosecutors are awaiting lab results from exhumed bodies before final charging decisions.
