It was determined that the word 'pinhole' (Sibop) meant 'judge', 'concerto' meant 'expert' and 'opera' meant 'court' in the conversation between Cem Uzan and his brother.
In the telephone talks between Cem Uzan and Hakan Uzan, it was seen that Cem Uzan asked meaningless questions as 'did you go to concerto?' or 'did you listen to the opera?' and had coded answers for his coded questions.
The words 'concerto' and 'opera' were used again later and attracted attention in the calls done with Muttak Ayvaz and Ali Cenap Ermutlu as 'Hakan has not gone to opera yet, did not you arrange it as I told you?'.
In many calls between Uzan Brothers, it was seen that they mentioned about somebody they call 'sibop'. In the last calls the Uzan brothers talked about the pinhole which they are no longer hopeful of: "Pinhole will not be able to arrange this thing, he has not solved it for months. He can not arrange it after this time, we should eliminate him."
