The Court of Justice of São Paulo has ruled that 68-year-old Elizabete Arrabaça will face a jury trial for qualified homicide and procedural fraud. Arrabaça is accused of poisoning her daughter, Nathália Garnica, with carbofurano, also known as ‘chumbinho’. 

Prosecutors further allege that Arrabaça and her son, physician Luiz Antônio Garnica, conspired to poison his wife, Larissa Rodrigues, to prevent the division of assets and facilitate a relationship between Luiz and a mistress. The prosecution suggests the motive was financial, citing Arrabaça’s significant debts resulting from a gambling addiction. Arrabaça has denied the allegations, maintaining she had no knowledge of the poison and was merely visiting her daughter due to illness.
