According to the backinfo I got, an unidentified man, believed to be either Bolivian or Peruvian, was attacked with a knife at a party in a Latin community in São Paulo, Brazil. The man had to IDs on him, and the wounds he sustained prevented him from being able to answer any questions.
The incident happened in Coimbra Street, in Zona Brás. There is a large Latin community in this part of São Paulo, most of them being Bolivians or Peruvians.
