The Turkish entertainment world is reeling from the sudden and tragic loss of Erol Köse, a renowned producer and former dentist, who died on March 23, 2026, after reportedly falling from the 16th floor of his residence in the Ağaoğlu 1453 complex in Sarıyer, Istanbul. Köse, a figure who shaped Turkish pop music and stirred headlines with his outspoken commentary, was 61 years old at the time of his death, according to reports from APA Türkiye and other Turkish media outlets.
The incident occurred during midday hours at Köse’s high-rise apartment, sending shockwaves through both the music industry and the broader public. Emergency and police teams responded swiftly to the scene, but the circumstances surrounding his fall have prompted an official investigation. The Istanbul Chief Public Prosecutor’s Office announced that it had launched an ex officio inquiry into the suspicious nature of Köse’s death, promising that the results of their investigation and autopsy would clarify the cause in due course, as reported by DHA and T24.
At the heart of the investigation are several poignant and troubling details. Police discovered a handwritten note at Köse’s home. In it, he wrote, “Due to my ALS disease, I was forced, the responsibility is mine. Take good care of my cat.” This brief but powerful message has fueled speculation about the state of Köse’s mental and physical health in his final days. According to initial statements from Mevlüt Y., a friend and cohabitant, Köse had been battling psychological disorders and heart disease, and had not left the house for about three months. Mevlüt Y. told police he occasionally helped care for Köse and, on the day of the incident, found his friend lying on the ground after returning from the building’s lobby.
Further adding to the complexity of the case, singer Yaşar İpek revealed that Köse had transferred all the rights to his musical works to his daughter just a week before his death. “I’m in shock, I wish this were a nightmare. Erol abi has been someone I’ve known since I was six. He was like family to us, and we lived in the same complex for the past few years. Just recently, he told me, ‘I’m working on new things, hopefully you’ll visit one day.’ Erol abi was not someone who would throw himself out of despair. I just learned from a friend that about a week ago, he transferred all rights and earnings from his works to his daughter. He did this suddenly, for no apparent reason,” İpek told reporters, according to Medyascope.
Köse’s daughter, Dijan Nazlan, reportedly studies abroad. Köse is survived by her, the product of his first of two marriages. Throughout his life, Köse was as much in the public eye for his personal life as for his professional achievements. He was known for weathering dramatic episodes, including surviving two separate shootings—one to his heel and another to his leg—allegedly for refusing to pay protection money to the mafia, as reported by Haber Merkezi.
Born in Elazığ in 1965 to a family with a military background, Erol Köse’s journey into the world of entertainment began while he was a student at Hacettepe University Faculty of Medicine. His career took a dramatic turn when he joined the Komedi Dans Üçlüsü (Comedy Dance Trio), a group that became a staple of late 1980s Turkish television with their humorous songs and quirky dance routines. The group’s popularity opened doors for Köse, but unlike his bandmates who left school, he honored his family’s wishes by completing his medical studies. Later, he would also graduate from Istanbul University’s Faculty of Dentistry, though he ultimately chose not to pursue a career in dentistry.
After the group disbanded, Köse transitioned into music production at the suggestion of singer Deniz Arcak. The 1990s and 2000s saw Köse rise to prominence as a producer, working with some of Turkey’s most celebrated pop artists, including Tarkan, Gülşen, Sertab Erener, Hande Yener, Murat Boz, and Ayna grubu. His company, Erol Köse Production, became a powerhouse in the Turkish music industry, launching the careers of many young talents and shaping the sound of a generation. According to Milliyet and Yeniçağ, Köse was instrumental in producing debut albums for artists like Atilla Taş, Nihat Doğan, and Ferhat Güzel.
Köse’s influence extended beyond music production. He was also a frequent television commentator, known for his sharp critiques and sometimes controversial statements. His forthright style made him a fixture in the Turkish media landscape, both feared and respected for his willingness to “expose” industry secrets and call out public figures. In the 2000s, he briefly entered politics as a parliamentary candidate for Cem Uzan’s Young Party and partnered with Hakan Uzan to run a music company and organize concerts.
Despite—or perhaps because of—his high-profile career, Köse’s life was marked by both triumph and turbulence. His refusal to bow to criminal threats, his candidness on television, and his sometimes sensational social media presence kept him in the headlines. In his private life, Köse was twice married, and his first marriage produced his only child, Dijan Nazlan.
At the time of his death, Köse was said to have been living a reclusive life, rarely leaving his home and relying on close friends for care. The discovery of his handwritten note and the accounts of those closest to him have prompted difficult conversations in Turkey about mental health, chronic illness, and the pressures of public life.
As the investigation continues, fans and colleagues alike are left to reflect on the legacy of a man who shaped Turkish pop culture for decades. Whether producing chart-topping albums, surviving personal trials, or stirring debate on national television, Erol Köse’s presence was impossible to ignore. His sudden death, still wrapped in questions, has left a void in the world he helped define.
For now, the Turkish music scene mourns a complex and influential figure, awaiting final answers about his final moments while remembering the indelible mark he left on their industry and their hearts.
