Turkish judicial sources said on Tuesday that an in-depth investigation has been launched into unsolved murder cases between the years of 2000 to 2013 to determine whether they have links with the outlawed parallel state structure which is also known as the Gulenist Movement.
The Office of Investigation into Crimes Committed Against Constitutional Order will be in charge of examining the files of former murder cases, which remain unsolved, for any evidence of links to the illegal group.
The “parallel state” is purported to be comprised of a group of bureaucrats embedded in the country's institutions, including the judiciary and the police, which are suspected to be part of the "Gulen movement" led by US-based preacher Fethullah Gulen and his supporters which the Turkish government alleges are plotting to undermine it.
An extensive investigation into the group had begun after the movement was accused of attempting to overthrow the elected Turkish government via judicial coup last December.
A secret circle within the Gulen Movement, was also determined as a national security threat for Turkey by the National Security Council.
The judicial sources also stated that the newly-introduced inquiry will include all unidentified murder cases during the whole 13 year period.
The murder of Behcet Oktay who was the president of Ankara police's special operations department in February 2009 and the killing of academic Necip Hablemitoglu in December 2002 will be among the cases which will be investigated.
The officials will also inquire into the death of candidate judge Didem Yaylali in August 2013 and the killing of a member of Turkey’s Council of State Mustafa Yucel Ozbilgin in May 2006.
Moreover, police intelligence and anti-terror units will be reportedly involved in the investigation.
