In the indictment, it was stated that Güllü fell from the window of her daughter Tuğyan's room, hit the concrete floor from a height of 18.17 meters, and died as a result of internal bleeding due to skull and vertebra fractures and numerous internal organ and major vascular injuries. It was also stated that in the toxicology examination, 3.53 promil alcohol was detected in Gül Tut's blood, the drugs used were not at toxic levels and there was no medical evidence that she was poisoned to death.
It was determined that on the night of the incident, Tuğyan Ülkem Gülter asked her friend Sultan Nur Ulu to sing the song 'Malkata', which her mother loved very much, and that the song was started on her mobile phone when Güllü came out of the bathroom. Hearing the music, Gül Tut said, 'What the hell is that?' It was recorded that he came to his daughter's room, accompanied the music with the people in the room, and played a novel style for a while. The prosecutor's office stated that the song was opened specifically to bring Gül Tut to the room where the incident occurred and that this was part of the planned action.
In the indictment, it was stated that Istanbul Technical University made a detailed examination of the camera audio recordings of the moment of the incident. In the expert report, it was stated that just before the fall, a young female voice said "Let's see you" in a sarcastic and cheerful tone. The prosecutor's office concluded that these words were said by Tuğyan Ülkem Gülter. In the indictment, it was stated that immediately after these words, the suspect grabbed his mother with both hands under her hips, swept her off her feet and threw her out the window.
It was stated that Sultan Nur Ulu, who was in the room at the time of the incident, said in the early stages of the investigation that Gül Tut was drunk and fell from the window, but later in her statement she explained that the incident happened differently. Sultan Nur Ulu's statement, stating that Tuğyan grabbed her mother with both hands under her hips while Gül Tut was facing the window, took her off her feet and threw her down was also included in the indictment. In the recorded phone conversation with the witness's lawyer, it was determined that Tuğyan said that he did not want to pay for what he did and that he would go to the prosecutor's office and tell the truth. The prosecutor's office evaluated that this audio recording supported the witness's later statement.
“ONE DAY I WILL THROW IT OUT THE WINDOW AND KILL IT”
In the indictment; Many messages and witness statements were included, allegedly showing that Tuğyan Ülkem Gülter wanted his mother to die months before the incident. Three witnesses claimed that Tuğyan told them that he would throw his mother out of the window one day and kill her. Another witness said that the suspect said that his mother or one of him would die. The suspect's ex-girlfriend K.E. and the messages he sent to his relatives included: 'I'm tired of this mother', 'Let her die', 'Let this woman die', 'She's not dying, when?' It was stated that he used expressions such as 'I will do something big to him'.
It was also included in the indictment that Tuğyan sent a message to her ex-boyfriend K.E. about 2 months before the incident, saying, "My mother is going to throw herself out soon." The prosecutor's office evaluated this message as one of the indicators of the suspect's 'mental preparation process' for his action.
In the raw version of the camera recordings found in the house, it was determined that 3 different impact and impact sounds were heard at short intervals before Gül Tut fell to the ground. In expert evaluation; It was stated that the period of approximately 1.9 seconds between the second and third impact sound largely coincides with the time between Gül Tut's exit from the window and her hitting the concrete floor. It was stated that Gül Tut was approximately one meter away from Tuğyan and Sultan in the room, but no screams or rescue reflexes were heard from either person for approximately 7 seconds after the first impact sound. The prosecutor's office noted that this situation indicates that Tuğyan and Sultan saw the fall and that the incident was not a sudden accident as described.
“THE PRESENCE OF EXTERNAL FORCE OR CONTACT IS HIGHER THAN THE POSSIBILITY OF ACCIDENT”
No lubricant was found in the samples taken from the floor of the room where the incident took place. It was stated that there was no evidence of suicidal thoughts in Gül Tut's medical records, and many witnesses reported that the singer was afraid of heights. The expert committee expressed the opinion that, considering Gül Tut's body structure and the height of the window, it was more likely that there was an external force or contact for her to fall backwards than the possibility of an accident. The Institute of Forensic Medicine noted that it cannot be medically distinguished whether a fall from a height occurred by suicide, an accident, or the influence of another person, and that the incident should be clarified by a forensic investigation.
In the indictment, it was stated that after the incident, Tuğyan Ülkem Gülter asked her ex-boyfriend K.E. to share her phone screen and delete the messages between them. It was stated that the suspect pressured K.E. to remain silent during the live broadcast, not to talk about the night of the incident and the problems between him and his mother, and asked him to say that his relationship with his mother was good. The prosecutor's office also noted that Tuğyan tried to keep Sultan Nur Ulu, the only eyewitness of the incident, with him at all times, followed her while she was meeting with someone else and threatened her not to tell the truth.
IT WAS DETERMINED THAT THEY MADE A PHONE CALL ABOUT GOING ABROAD.
It was recorded that Tuğyan and Sultan had a phone conversation with a person in a hotel where they stayed in Istanbul after the incident, about how they could go abroad. In the meeting; Sultan was asked whether he was threatened by Tuğyan, and Tuğyan intervened and said, 'Of course I am. It was stated that he said, "If he leaves me alone one day, I will not forgive him." It was also shown in the indictment that the suspect changed his phone after the incident, reset his device to factory settings and asked for some messages to be deleted.
IT WAS REVEALED THAT HE REVIEWED THE 'SERIAL KILLER CASE' GAME ON HIS PHONE
In Tuğyan Ülkem Gülter's digital materials, questions such as 'When are drugs cleared from the hair?', 'When is cocaine removed from the hair?' and 'Can methamphetamine be found in hair?' It was determined that he made internet searches such as: It was also stated that the suspect was viewing a board game called 'Unsolved cases, serial killer case, detective game, finding the criminal' on the internet.
