Unknown Gender History: “Sao Paulo Girl,” Brazilian Teen Serial Killer Murdered 30 Males

NOTE: Because the prisoner in question is under-age, her name was not made public. Presumably her case is being handled in secret because she was a minor when she confessed and thus there may not be any further news on the case. For convenience, we are giving her the moniker of “San Paulo Girl” in our discussions of female serial killers.

On July 6, 2009 in City of São José do Rio Preto in the state of Sao Paulo, Brazil a 17-year old schoolgirl who had been arrested in a street scuffle in Gymslip district of that city made a confession to police that she had, beginning at the age of 15, committed 30 murders. All the victims, according to her, were young men.

She asserted she had over a period of two years stabbed the 30 young men to death motivated by a desire “for money, revenge and to bring justice”. During her interrogation, which was videotaped, she was calm and smiled as she related her story, telling police: “I don’t have enough courage to hold a gun — but I can hold a knife.”

She told detectives she decided to confess in order to avoid the risk of later being found out and charged as an adult: “I am confessing because I promised I would do so before becoming 18 — to avoid upsetting my family.”

The girl told how she always used the same knife — butchering one man for throwing a glass of brandy in her face in a bar fight. But police were last night still unclear about what drove her to keep on killing.

Shortly after the arrest some speculated that the girl might have been hired by an organized crime syndicate as an assassin because she was so innocent-looking.

An investigation was conducted to verify if her confession is true, and so far she has provided elaborate details regarding 11 of the killings. But there have been no public reports on the case since late 2011.

The schoolgirl stunned cops by owning up to a serial killing spree that started when she was a 15-year-old. She told detectives she wanted to confess before she turned 18 and could be tried as an adult. The girl - too young even to be named - said she began targeting men in her home city of Sao Paulo, Brazil "for money, revenge and to bring justice". She even SMILED as she reeled off her list of victims - which is feared to make her the world's most prolific teenage serial killer. She calmly bragged to police: "I don't have enough courage to hold a gun - but I can hold a knife. "I am confessing because I promised I would do so before becoming 18 - to avoid upsetting my family." Butchering The schoolgirl told how she always used the same knife - butchering one man for throwing a glass of brandy in her face in a bar row. But police were last night still unclear about what drove her to keep on killing. Sources said one theory is she was hired by gangland bosses as an assassin because she was so innocent-looking. The teenager's sensational confession came after she was arrested over a Sao Paulo street fight. (End of this story. The article ends with separate Brazil news story: a scandal involving Wallace Souza, TV crime show host.)
