text: Trial of coup leaders After the 2010 constitutional referendum, an investigation was started regarding the coup, and in June 2011, the Specially Authorized Ankara Deputy Prosecutor's Office asked ex-prosecutor  to forward a copy of an indictment he had prepared for Kenan Evren. Kayasu had previously been fired for trying to indict Evren in 2003.
  In January 2012, a Turkish court accepted the indictments against General Kenan Evren and General Tahsin Şahinkaya, the only coup leaders still alive at the time, for their role in the coup. Prosecutors sought life sentences against the two retired generals. According to the indictment, a total of 191 people died in custody during the aftermath of the coup, due to "inhumane" acts. The trial began on 4 April 2012. In 2012, a court case was launched against Şahinkaya and Kenan Evren relating to the 1980 military coup. Both were sentenced to life imprisonment on 18 June 2014 by a court in Ankara. But neither of the two was sent to prison as both were in hospitals for medical treatment. Şahinkaya died in the Gülhane Military Medical Academy Hospital (GATA) in Haydarpaşa, Istanbul on 9 July 2015. Evren died at a military hospital in Ankara on 9 May 2015, aged 97. His sentence was on appeal at the time of his death.
