A Brazilian woman who allegedly spent years pretending to be a child has been sentenced to 18 months in prison after deceiving a couple who took her into their home.

Amanda Maria Souza de Oliveira, 38, reportedly convinced the couple that she was a 12-year-old girl in need of protection and care. According to reports, she allegedly went as far as pretending to have disabilities and the mental age of a child as part of the elaborate deception.
The extraordinary case began in Joinville, in southern Brazil, after Oliveira attended services at an evangelical church.

How the deception began
Oliveira initially presented herself as an 18-year-old named Gabriele who was looking for employment. A pastor reportedly introduced her to a couple who felt sympathy for her situation and offered her somewhere to stay.
However, according to the case details, her story gradually changed.
She eventually claimed that she was actually 12 years old and had escaped abuse in the northern Brazilian state of Pará. She reportedly told the couple that although she appeared to be an adult woman, her appearance was the result of hormonal supplements that her father had allegedly forced her to take when she was younger.
The couple believed her story and reportedly began treating her as a child in need of protection.
Oliveira allegedly reinforced the deception by behaving like a young child. Reports said she drank milk from bottles and used dummies, while also pretending to have physical and intellectual disabilities.
The behaviour reportedly convinced the couple that they were caring for a vulnerable child.
Allegations of financial deception
The situation became even more complicated when Oliveira allegedly persuaded the couple to spend money on her needs.
Among the expenses reportedly connected to the deception was a course of weight-loss medication.
The couple apparently remained unaware of her true identity until a relative began questioning her story.
The relative reportedly conducted online research and discovered reports from 2023 involving a woman named Amanda who had allegedly carried out a similar deception in Rio de Janeiro.
The discovery raised serious questions about Oliveira’s identity and past.

Police expose the truth
When police eventually arrived at the couple’s home, Oliveira reportedly abandoned the child persona almost immediately.
According to reports, she began speaking to officers in her normal adult voice.
Investigators subsequently uncovered information suggesting that the woman was not a child at all but a 38-year-old adult who had allegedly been using similar tactics for years.
Oliveira later admitted that she had deceived people, although she denied intending to scam anyone.
“It is clear that I deceived people; I lied. But I did not intend to scam anyone,” she reportedly told investigators.
Authorities allegedly discovered that she had used the same type of deception in several Brazilian states.
A deception spanning years
Brazilian Court records reportedly indicate that Oliveira had pretended to be a child in at least nine states, including Paraná, Rio de Janeiro, Minas Gerais, Goiás, Ceará, Rio Grande do Sul, São Paulo, Rio Grande do Norte and Mato Grosso do Sul.
Investigators reportedly found evidence suggesting that the unusual behaviour had continued for approximately 15 years.
The case therefore became much bigger than a single incident involving the couple who took her in.
Brazilian Authorities were faced with allegations of a long-running pattern in which Oliveira allegedly presented herself as a vulnerable child to gain sympathy, accommodation and support.

Court rejects mental illness defence
During court proceedings, Oliveira’s lawyers reportedly argued that she should not be held criminally responsible because of mental health issues.
They described her behaviour as a “survival strategy” adopted by a deeply troubled woman who had allegedly been deprived of love and affection during her own childhood.
However, a Brazilian judge in Santa Catarina rejected the defence.
The Brazilian court concluded that Oliveira had acted deliberately and consciously and was therefore criminally responsible for her actions.
She was subsequently sentenced to 18 months in prison for fraud.
Lawyers plan to appeal
Oliveira’s legal team has reportedly indicated that they intend to appeal the conviction.
Her lawyers maintain that her actions should be understood in the context of her personal history and psychological difficulties rather than simply as a calculated attempt to defraud people.
Prosecutors, however, argued that imprisonment was appropriate because the deception allegedly caused both financial and psychological harm to the family involved.
The case has attracted considerable attention in Brazil because of the extraordinary lengths Oliveira allegedly went to maintain her false identity.
From claiming to be a teenager seeking employment to later presenting herself as a 12-year-old child, her story reportedly continued to evolve as the couple became more involved in her care.
For the couple, what initially appeared to be an act of kindness towards a vulnerable child ultimately became a shocking discovery.
The case also highlights the difficulties families and communities can face when attempting to help strangers whose personal histories cannot easily be verified.
Oliveira’s appeal will determine whether the sentence remains in place, but the bizarre circumstances surrounding the case have already made it one of Brazil’s more unusual recent fraud stories.
