The investigation conducted by the Silivri Chief Public Prosecutor's Office into the suspected "intentional killing" of Kaşif Kozinoğlu is being carried out from multiple angles.
While it is alleged that there is a connection between Kozinoğlu's death and the series Kurtlar Vadisi, the claim that the series' first producer and director, Osman Sınav, was also threatened and left the production for this reason has resurfaced.
SINAV HAD SAID "IT WILL GO TO THE GRAVE WITH ME"
Osman Sınav had not made any public statement regarding why he left the Kurtlar Vadisi series and had said, "This will go to the grave with me as a secret."
Journalist Sinan Burhan stated that the person alleged to have threatened Osman Sınav was Enver Altaylı.

Altaylı had also been arrested within the scope of the Kozinoğlu investigation.
"I SPOKE WITH THE WITNESS TO THE EVENT"
Speaking on Tv100, Sinan Burhan used the phrase "I personally spoke with the witness to the event today" in his statement regarding the matter, and said that the person in question is Osman Aksu.
Regarding Aksu, Burhan said, "He is a retired teacher. This person will also provide testimony."

IT IS CLAIMED THAT SINAV WAS THREATENED BY ALTAYLI
According to the information provided by Burhan, Osman Aksu visited Tahsin Sena at an association in Avcılar. During this meeting, Aksu relayed that Osman Sınav had said he was being threatened.
According to Aksu's statement, Sınav used the words, "Enver Altaylı threatened me. He said, 'You will leave this series. We are going to change the format of this series.'"
"Enver Altaylı IS A DANGEROUS MAN"
Allegedly, Osman Sınav asked for help from Tahsin Sena, whom he met with. Sena, in turn, said to Sınav, "Enver Altaylı is a dangerous man, what should I do, I don't have the power."
It was claimed that Sena said he could help Sınav if he continued to be harassed after leaving the series.
