Tunceli Chief Public Prosecutor Ebru Cansu made significant statements regarding the investigation into university student Gülistan Doku, who has been unreachable since 2020. Stating that the investigation file has reached 14 folders, Cansu explained that the puzzle began to unravel when a SIM card belonging to Doku gave a signal in Ankara.
In the Gülistan Doku investigation that has been the talk of Turkey, Tunceli Chief Public Prosecutor Ebru Cansu, who lifted the veil of fog, broke her silence on TRT Haber screens. After taking over the investigation, Chief Prosecutor Cansu thoroughly re-examined the 7-folder file, expanding it to 14 folders, and shared the behind-the-scenes details of the operations and the new findings obtained.
"WE CHASED THE SIM CARD THAT SIGNALED FROM ANKARA"
Stating that the biggest breakthrough in the file began with a SIM card detail that had gone unnoticed, Chief Prosecutor Cansu said the following:
"The first thing that caught my attention in the file was that Gülistan's SIM card was pinging in Ankara. When I saw it pinging in another province, I followed up on it, and through chain questioning we reached certain data. The information had only come that it had been inserted into the device, but there was no investigation into who might have used it before or who might have inserted it. After that stage, when I continued investigating, it led me to Gökhan (the dismissed police officer suspect)."
HOSPITAL RECORDS DELETED: DOCUMENTS WERE NONEXISTENT
Cansu also clarified the allegation of 'deleting records' that led to the arrest of Çağdaş Özdemir, the then Chief Physician of Tunceli State Hospital, stating that they found discrepancies between Polnet (Police Information System) records and hospital documents:
"When we requested the treatment documents from the hospital, there was a contradiction in the dates on the documents received. A date on which a hospital entry appeared in the Polnet record was not found in the hospital treatment documents at all. This seemed suspicious to us. Currently, inspectors from the Ministry of Health are conducting the necessary examinations at the hospital."
DIGITAL MATERIALS BEING EXAMINED, BASE STATION RECORDS UPDATED
Stating that base station (HTS) studies were conducted again in the Youth Center and Sarı Saltuk Viaduct areas in line with the statements of the secret witness, Cansu also announced that the digital materials of all suspects have been seized:
"The digital materials (mobile phones, computers, tablets) of all suspects have been seized, and permission for examination has been obtained. Examinations by cybercrime experts are ongoing."
"I PERSONALLY JOINED THE JASAT SEARCHES"
Referring to the tireless efforts day and night, over mountains and hills, to find Gülistan Doku's body, Chief Prosecutor Cansu said she personally went to the field and took part in the work. Cansu said, "We went to many areas. Wherever there were mountainous, forested areas, shelters, caves that could be in Tunceli, in the hope that we could find it with the capability of the device in our hands, I personally was with the gendarmerie in all searches, without hesitation."
Stating that the searches are currently ongoing in the field with a special 30-person JASAT team, Cansu noted that both equipped technical devices and expert teams have been sent from Ankara to support Tunceli.
THANKS TO MINISTER GÜRLEK
At the end of his statements, Chief Prosecutor Ebru Cansu thanked the Ministry of Justice for the support they felt behind them throughout the investigation, saying, "We felt their support fully behind us. In your presence, I thank both our Minister Mr. Akın Gürlek and our Deputy Minister Mr. Can Tuncay for their support."
