After the murder, an investigation was launched and statements were taken from the families of Semih, İkbal and Ayşenur. Semih Çelik's mother, Hafize Çelik, stated that her son was sick, and that she took him to the doctors and also warned Uzuner's family about the situation. She told Uzuner's family that they had to go into hiding to prevent her son from harming her. She said that her son and İkbal were going to commit suicide together, but İkbal later changed her mind and she constantly called him after. She added in her statement that Semih had stabbed himself in the heart. She claimed that İkbal's family did not take the necessary precautions. Semih Çelik's father, Adem, stated that his son wanted to kill himself as well. He said that his son's teacher called him during his high school years and told him that his son should stay away from a friend at school. He added that Semih spent a lot of time on the computer Adem had bought for him, and that when his family entered his room, he panicked and quickly turned it off, as there was many disturbing pictures and notes that were psychotic and immoral. Adem added that he couldn't find out what he was doing on the computer as his files were encrypted, and that his son did not want to study and graduated from high school externally. Çelik's mother also said that her son encouraged her daughter to commit suicide, and that strange drawings resembling the
devil were in his room. When she asked about the drawings, her son responded with something along the lines of "You wouldn't understand, our mindsets are different," that he was a butcher and used drugs. It is confirmed that Semih Çelik had started a relationship with Ayşenur Halil, who was identified as a friend from the high school he had dropped out of. Halil had visited Çelik's house, and they had spent time together. Semih called his father on the day of the incident, and said that Ayşenur was in his room and told him that he should not come home. When his father, Adem, went home, he found Ayşenur's body in his bed with her neck bleeding from the slit cut by Çelik with one of his butchering knives. Adem also stated that Semih asked his father questions about death at home, had imaginary delusions, and kept many knives in his room. He added that he was Muslim before he was 16, and questioned many things about the world, including his religion. He left Islam shortly after. He also started to question existentially with the COVID-19 pandemic. Semih's guidance counselor told Adem that he had a talent for programming, so he bought him a computer. It was determined upon examination of Çelik's phone that he had contact with people who identified themselves as Turkish
incels. Following the murder, provocative and supportive posts were made by incel groups. Upon this, the chief public prosecutor's offices took action and detained the suspects. Then, on October 9, 2024,
Discord was blocked for the 8 million registered Turkish users on the app. They are still banned to this day. == Reactions ==
