Developments in the investigation of singer Giorgos Mazonakis' death

The investigation into the death of singer Giorgos Mazonakis at a private clinic on Karneadou Street in Kolonaki, Athens, on September 9, 2026, continues with new testimony and forensic findings. A nurse at the facility testified before the 32nd regular investigator, admitting that she initially provided a false arrival time for the artist under the instruction of the accused doctor to maintain a 'common line'. She also revealed that two plasmapheresis procedures were performed simultaneously by the doctor, and that the singer was administered sedation, requiring an anesthesiologist to be called. Furthermore, the Athens Medical Association reported that the facility’s equipment was used outside of official operating hours, specifically late at night and on weekends.

The investigation now focuses on financial aspects, including messages between the singer and the 56-year-old doctor regarding treatment costs. Evidence has emerged that the facility's defibrillator was not functioning properly during the emergency, requiring the staff to call the supplier for instructions. The primary investigator has requested the lifting of communication privacy for all involved parties. The two arrested doctors have decided not to appeal their pre-trial detention, opting to wait for further evidence before potentially requesting house arrest in late October.
