Overview

• Prosecutors in Guarulhos accuse Ana Paula Veloso Fernandes of four murders by poisoning between January and May 2025 and describe her as a serial killer.
• The alleged victims are Marcelo Hari Fonseca and Maria Aparecida Rodrigues in Guarulhos (SP), Neil Corrêa da Silva in Duque de Caxias (RJ), and Tunisian national Hayder Mhazres in São Paulo, whose body was repatriated without local autopsy.
• Investigators cite a pattern of calculated access through friendship or romance, suspected use of "chumbinho" (terbufos) in food or drink, use of aliases, and returning to or remaining at crime scenes.
• Two women are also in custody: her twin, Roberta Cristina Veloso Fernandes, and Michelle Paiva da Silva, who allegedly paid about R$4,000 to have her father poisoned with feijoada, with WhatsApp exchanges using the code "TCC" flagged as evidence.
• Neil's body was exhumed for toxicology, forensic results remain pending across cases, and police forces in São Paulo and Rio continue to coordinate and search for additional potential victims.
