Woman who posed as 12-year-old for years arrested after deception exposed

Amanda Maria Souza de Oliveira was thirty-eight years old when she walked into the Recife social services system in 2023, claiming to be a twelve-year-old girl named Gabrielly. She would carry a stuffed bear under her arm. She spoke in a high, childlike voice and moved her body in exaggerated, youthful ways. She said she had been sexually abused. She said she had needles embedded in her skin. The psychologists and social workers who met her did not believe her.

One psychologist who treated her at a Recife facility that summer remembers the performance clearly. The woman's voice was artificially pitched, her gestures deliberately juvenile, but her face and hands and the way she held herself betrayed her real age. When the staff tried to talk about getting her identification documents, she became irritable and evasive in ways a genuine child would not. The psychologist recalls the team discussing whether she had committed a crime, whether she suffered from a cognitive disorder, whether something else entirely was happening. What they knew was that she did not appear to be twelve. She did not appear to be a minor at all.

In July 2023, the Specialized Social Outreach Service found her on the streets and brought her to the Irmã Dulce dos Pobres shelter in the central São José neighborhood. The shelter served adults, so she could not stay. The Recife Guardianship Council was called and transferred her to the Raio de Luz reception house in the Madalena district, which was designed for adolescents in vulnerable situations. Inconsistencies in her story prompted staff to file a police report. She was released. Ten days later, she appeared at the Centro POP José Pedro in the southern Boa Viagem neighborhood, this time claiming to be eighteen—the minimum age for adult shelter admission. The psychology team noticed her infantilized voice, her youthful mannerisms, her evasiveness about personal details. They checked her records and recognized her as the same woman from weeks before. She left the facility on her own, and that was the last official contact the city had with her.

But the deception had been running much longer and much wider than Recife. Across seven states—Santa Catarina, São Paulo, Rio de Janeiro, Minas Gerais, Rio Grande do Sul, Goiás, and Ceará—she had presented herself as a child. In 2017, a support house in Belo Horizonte had admitted her with approximately two hundred needle wounds covering her body. In September 2023, months after leaving Recife, she checked into a children's hospital in Florianópolis, where doctors found multiple needles lodged in her flesh. The self-inflicted injuries were part of the performance, evidence of the abuse she claimed to have suffered.

In Joinville, Santa Catarina, she lived as an adopted daughter in a family home for fourteen months. She told them she had autism and other medical conditions. She maintained the fiction completely. On June 2, 2026, police arrested her at that residence. She confessed to the entire scheme. The family that had sheltered her, fed her, cared for her—they had been deceived for over a year. They had believed they were helping a traumatized child. Instead, they had been living with a woman who had constructed an elaborate false identity and exploited their compassion with calculated precision.

The case now sits in the hands of law enforcement, raising questions that extend far beyond one woman's deception. How does someone move through multiple social service systems across multiple states without detection? What gaps in communication and verification allowed her to access shelters meant for children repeatedly? The psychologists in Recife had their doubts. They noted the theatrical quality of her performance. But doubt is not certainty, and in systems designed to help vulnerable people, the cost of refusing to help someone who might genuinely need it is high. She understood that. She used it.
