A Brazilian teenager admitted having stabbed to death 30 men in four different states between 2006 and the last days, the police told the press today. The 17-year-old girl confessed after being arrested during a street fight in Sao José de Rio Preto (Sao Paolo province).

"I don't have enough courage to hold a gun, but I can hold a knife," she said. "I am confessing because I promised I would do so before becoming 18, to avoid upsetting my family," she told the police officers who arrested her. According to the police, she confessed now to avoid being prosecuted as an adult.

She said she started killing when she was 15. After she admitted those crimes, the police started checking registered murders. So far, eleven cases correspond to her story. All are from Aparecida Do Taboado (Mato Grosso Do Sul state).

But other cases are being checked in the Sao Paolo, Mato Grosso and Minas Gerais states. According to the police sources, the teenager girl said she commited those murders (all with the same knife) for "money, revenge and for bringing justice."

The police suspects she was contracted by criminal organizations. She will be transferred to the Aparecida Do Taboado juvenile hall, her city of residency.
