When the lawyers of the Dink family investigated the security camera records which were screening the street where the assassination took place, they identified four suspects speaking with their cellphones. Thereupon they requested the GSM call operation logs of the Şişli region Turkish Telecommunication Authorities around the time when the murder happened and the time where they identified the cell phone usage from the security cameras. Two major GSM providers reported that they do not have any GSM base station in that region, hence they cannot identify anything.
