In a significant development in a cold case, a 36-year-old woman was arrested in Bento Gonçalves, Brazil, on December 3rd, four years after the murder of her ex-husband, Roberto Fortunato Dall Agnol, a 48-year-old lawyer. Initially treated as a robbery resulting in death, the investigation has taken a dramatic turn, with authorities now suspecting that the woman may have been the mastermind behind the murder, as declared by delegate Raquel Peixoto. The case had previously been classified as a robbery gone wrong, during which it was alleged that intruders shot Dall Agnol after failing to access his bank account via a mobile app.
