The Silivri Chief Public Prosecutor’s Office in Türkiye is continuing investigative measures into the death of Kaşif Kozinoğlu, a former official of the National Intelligence Organization (MİT), who died at Silivri Prison in 2011.
Operative Information Center-OMM reports that the information was provided by official sources in Türkiye’s law enforcement agencies.
As part of the investigation, former intelligence officer Enver Altaylı, who was previously prevented from being questioned because of health problems and was convicted in a FETÖ case, was brought from the prison where he is being held to Silivri Courthouse to be questioned as a suspect. His questioning by the prosecutor’s office is continuing.
Kaşif Kozinoğlu was taken to Silivri State Hospital after his health suddenly deteriorated at Silivri No. 1 L-Type Closed Prison on Nov. 12, 2011, but doctors were unable to save his life. Although the investigation conducted at the time was closed on April 10, 2012, the Ministry of Justice’s Department for Investigating Unsolved Crimes reopened the case for review.
The previous decision to close the case was overturned by a decision of the Silivri Criminal Judgeship of Peace dated Aug. 26, 2026. The court also imposed a confidentiality order and established a special investigation team.
Exhumation proceedings and forensic examinations were carried out under a court order to determine the exact cause of Kozinoğlu’s death and whether third parties were involved. Former Silivri Chief Public Prosecutor Ali İşgören, prison prosecutor Necip Doğan and former journalist Osman Arslan were arrested as part of the investigation. House arrest was imposed on Kozinoğlu’s cellmates Hasan Ataman Yıldırım and Hasan Atilla Uğur, while several other officials were barred from leaving the country. Raci Şaşmaz, Bahadır Özdener and Cüneyt Aysan, screenwriters of the television series “Kurtlar Vadisi Pusu,” were also summoned to the prosecutor’s office as persons with information and questioned.
Enver Altaylı was sentenced to 23 years and four months in prison on charges of “membership in an armed terrorist organization” and “political and military espionage.” Türkiye’s Supreme Court upheld the sentence in 2024.
