WITNESS: THERE WAS A DISPUTE OVER A GIRL BETWEEN THEM
The final hearing of the case was held today at the Zonguldak 2nd High Criminal Court. The hearing was attended by detained defendant Yunus Emre Coşkun, Celal Can Er's relatives, and the parties' lawyers. P.A.H., who testified as a witness at the hearing, stated that he saw the argument from his home's window and said, "There was apparently a dispute over a girl between them. Until that moment, they had no hostility."
Another witness, H.H.A., stated that a disagreement occurred between the parties due to a friend request sent via social media and said, "I know Yunus Emre and Celal from before. There was apparently an issue of sending a request between them. Yunus Emre Coşkun, K.Ç., and I went to the park. First, I tried to calm them down. Celal threw a punch before Yunus Emre Coşkun got out. There was no room in the car. They went upstairs; I did not go up. When I realized the incident would escalate, I tried to call the police. Then, when I went upstairs, the incident had already happened."
DEFENDANT: I CANNOT SLEEP AT NIGHT
Making his defense, defendant Yunus Emre Coşkun said, "Until the incident, I had never even gone to the police station to give a statement. I deeply regret what I did. I cannot sleep at night. I wish such a thing had never happened. I experienced fear of death. I did not do it for another purpose. Everything happened for this reason."
15 YEARS IN PRISON
In its opinion on the merits, the public prosecutor requested, in line with the collected evidence and witness statements, that the defendant be punished for the crime of "intentional killing" and that his detention continue. The court panel sentenced Yunus Emre Coşkun to 15 years in prison for the crime of "intentional killing."
