A new demand has been raised in the court investigation into the mysterious death of Turkish singer Güllü.
Globalinfo.az reports that the lawyers of the late singer’s sister, Kader Tut, have demanded that the phone calls and base station data (HTS) of the persons who were in the house on the night of the incident be analysed.
The defence requested a detailed examination of the mobile phones’ communication data, as well as a determination of whether outside persons contacted those in the house by voice or video call at the time of the incident.
It should be recalled that the artist, whose real name was Gül Tut, died on 26 September 2025 after falling from the window of her sixth-floor apartment in a residential building in the Çınarcık district of Yalova.
Within the investigation launched after the incident, the singer’s daughter, Tuğyan Ülkem Gülter, and her friend Sultan Nur Ulu, who was with her at the time, were detained.
Gülter was arrested on suspicion of deliberately killing her mother, while a house arrest measure was imposed on Ulu.
The indictment alleged that Gülter pushed her mother from the apartment window.
On 9 October 2026, the Yalova 1st High Criminal Court found Tuğyan Ülkem Gülter guilty of deliberate murder and sentenced her to life imprisonment.
