WHO IS THE SICÁRIO

Luiz Phillipi Mourão was part of the “intimidation nucleus” from Vorcaro’s adversaries and opponents, according to the Federal Police. In the decision that authorized the operation this Wednesday (March 4), Minister André Mendonça, rapporteur of the case at the Supreme Court, cites two conversations between him and the banker that could be interpreted as intimidation:

  • threat against journalist – Vorcaro, who works at the newspaper O Globo, and states that “we had to have people following this guy to get everything from him”. Sicário responds: “I’m going to do this”. Afterwards, the banker declares that he wants to “give a break” in the professional;
  • threat against employee – in , Vorcaro says he was threatened by a maid and claims that “you have to grind this slut”. Sicário asks what to do. The banker then says: “Address everything”.

Here is what Mendonça says about Luiz Phillipi:

  • had a direct relationship with Vorcaro;
  • received R$ 1 million per month for your “illicit services” –the amount was paid through Fabiano Zaettel, also arrested in the operation this Wednesday (4th March);
  • was responsible for obtaining confidential information, monitoring people and “neutralization of situations considered sensitive to the interests of the investigated group”;
  • there are indications that he accessed and collected data from restricted systems of public bodies;
  • He was the one who coordinated the group known as “A Turma”, responsible for intimidating people.
