As part of the Kâşif Kozinoğlu investigation, Kurtlar Vadisi screenwriters Raci Şaşmaz, Bahadır Özdener, and Cüneyt Aysan went to the courthouse on September 14 to provide testimony as "persons with knowledge."
Following the screenwriters' testimony, Nevzat Yakışırboy, who joined the series in the 43rd episode, made posts on his social media account regarding Osman Sınav.
Claiming that Sınav was threatened by FETÖ members at the time, Yakışırboy stated, "Osman Sınav did not want to walk the path with FETÖ members."
In his post, the actor also included the following words directed at Sınav: "Oh, Osman, my teacher, why didn't you tell everything? They played you for a fool and you fell for it; these people couldn't even slaughter a chicken."

"THREAT" DETAIL ALSO DREW ATTENTION IN RACİ ŞAŞMAZ'S TESTIMONY
Raci Şaşmaz's testimony also contained notable details regarding Osman Sınav's departure from Kurtlar Vadisi, which Yakışırboy brought to the agenda in his post.
Şaşmaz stated that Sınav wanted to provide ideas and advice regarding the script, but that he did not accept this as he found it inappropriate.
Conveying that Sınav came to him after this request was rejected and said he had received threats, Şaşmaz stated that Sınav mentioned he had children and wanted to leave the series and hand it over to him.
Şaşmaz explained that this was how Sınav's departure from the series took place.
