Criminal complaint against Sultan and Caravan

The trial of Sultan Nur Ulu (25), for whom a prison sentence of up to 4 years is sought, has begun on the charge of "false testimony" regarding the death of Gül Tut (52), known as the singer Güllü in Yalova.

According to DHA, Ulu stated that Tuğyan Ülkem Gülter threatened and pressured him and said, "My lawyer at the time told me that I should tell at the right time. He said that I should tell after all the evidence was collected. I did this by listening to his words. When I moved away from Tuğyan, I told everything at the police station. I was afraid that he might put the blame on me."

In the incident that took place on September 26, 2025, on Vali Akı Street, Harmanlar District, Çınarcık district, Gül Tut died by falling from the window of her house on the 6th floor. As part of the investigation launched after the incident, her daughter Tuğyan Ülkem Gülter and her friend Sultan Nur Ulu, who was at home at the time of the incident, were detained. Within the scope of the investigation, a lawsuit was filed against Tuğyan Ülkem Gülter, demanding aggravated life imprisonment for the crime of "premeditated murder against the superior lineage", while a prison sentence of 2 to 4 years was requested for Sultan Nur Ulu, for the crime of "false testimony". Güllü's daughter, Tuğyan Ülkem Gülter, was sentenced to aggravated life imprisonment in the case where she was tried for the "premeditated murder" of her mother.

The trial in which Sultan Nur Ulu is being tried for the crime of "false testimony" with a request for a prison sentence of up to 4 years started today at the Yalova 5th Criminal Court of First Instance. Ulu and his lawyer were present at the hearing, and Tuğberk Yağız Gülter and his lawyers were present.

Sultan Nur Ulu said, "The reason why I couldn't tell the truth at first was that Tuğyan threatened me, saying, 'If I burn, you will burn too.' One day, when we were driving, he threatened me by saying, 'The brakes of the car are not working.' He was putting pressure on me. My lawyer at that time said that I should tell what happened at the right time, after all the evidence was collected. I did this by listening to his words. When I got away from Tuğyan, I told everything at the police station. The blame is on me." He demanded his acquittal, saying, "I was afraid that he might throw me away. That's why I couldn't tell the truth."

Tuğberk Yağız Gülter's lawyer, Rahmi Çelik, stated that they filed a new criminal complaint and said, "We filed a criminal complaint against the defendants Sultan Nur Ulu and Kervan Eminoğlu to the Yalova Chief Public Prosecutor's Office for the crime of 'deliberate murder with participation'. We request that the file be kept on hold due to the newly emerged expert reports."

The court decided to lift the judicial control decision against Sultan Nur Ulu and to wait for the requested files and postponed the hearing.

On the other hand, regarding the death of singer Güllü, the sounds from in-home security cameras were analyzed by the lawyers of his son Tuğberk Yağız Gülter, with two separate expert opinions. In the prepared report, the recordings included the words "Leave me alone" attributed to Güllü, Sultan Nur Ulu saying "Horse" and the statements attributed to Tuğyan Ülkem Gülter saying "Run, I don't have a mother, run", while the speeches stated to belong to the man were also added to the report. It was claimed that the male voice belonged to Tuğyan's ex-girlfriend Kervan Eminoğlu.
