The message reads: "Attention Celso Goncalves
Lenadro Goncalves (subrubim)
You are the next"
I think they are saying that Celso and Leandro are the next ones who they are coming for. My translator app did not translate the Goncalves part so it might be the names of two others. It is in Portuguese
Goncalves ([ɡõˈsaɫvɨʃ]; Portuguese for "son of Goncalo") is a Portuguese surname, variation of the Spanish surname González/Gonzales.
