Ongoing investigation into the death of singer Giorgos Mazonakis

The investigation into the death of Greek singer Giorgos Mazonakis, who collapsed during a plasmapheresis procedure at a clinic in Kolonaki on September 9, 2026, continues to reveal critical procedural failures. Two doctors remain in custody at Korydallos prison, while authorities are awaiting a judicial order to lift the secrecy of communications for all involved parties. A key point of inquiry involves a frantic phone call made by clinic staff to a medical equipment supplier during the emergency, where they requested help with a malfunctioning defibrillator without disclosing it was a life-threatening situation. The device, purchased in July 2022, was allegedly missing its battery at the time of the incident.

Testimonies highlight significant contradictions regarding the timeline and practices within the clinic. A 56-year-old nurse has provided conflicting statements to police and the prosecutor, alleging that medical staff were instructed on what to report. Additionally, hypnotherapist Nasos Komianos, who was in contact with the clinic, has been questioned; he admitted to initial skepticism about the clinic's practices but denied orchestrating the singer's appointment. Future proceedings include a potential request for house arrest for the detained doctors and further analysis of electronic evidence and witness testimony to determine the full extent of professional negligence.
