# Investigation and tributes following death of Giorgos Mazonа > Live situation record from CLSTR: https://clstr.news/situations/investigation-into-death-of-singer-giorgos-mazonakis > Updated: 2026-09-11T16:27:56.000Z. Sources: 197. Developments: 4. The investigation into the death of singer Giorgos Mazonakis at a private clinic in Kolonaki has intensified. Doctors Ioanna Gaka and Ilias Theodoropoulos have been arrested and face felony charges of causing death by exposure, which carry potential sentences of 5 to 10 years of imprisonment. The family’s lawyer has alleged a cover-up and is pushing for charges of manslaughter with intent. Police investigations have uncovered attempts to conceal evidence, including the digital deletion of appointments and a photograph of the singer on medical equipment, though forensic investigators successfully recovered these files. Significant timeline discrepancies persist: while doctors claimed the singer arrived at 16:00, video footage shows him entering at approximately 14:00. Although the apheresis procedure lasted roughly 42 minutes, emergency services were not summoned until 16:21, highlighting a critical 87-minute delay between the incident and the call to emergency services (EKAB). The Medical Association of Athens (ISA) has launched an ex officio disciplinary inquiry and is pursuing administrative procedures to recommend the suspension of the doctors' medical licenses to the Panhellenic Medical Association. The ISA stated it had been misled by the doctors and noted that two apheresis machines were found during a recent inspection, despite having missed them during previous checks in 2024 and 2025. The ISA also intends to participate in criminal proceedings to support the prosecution. Additional testimonies from clinic employees and former patients have raised concerns regarding unregulated treatments promoted as ‘detox’ or anti-aging methods. The Greek Hematology Society has also previously warned about the risks of unregulated alternative therapies and ‘longevity’ services. The incident has triggered widespread mourning across Greece and Cyprus, with tributes from artists including Natasa Theodoridou and Anna Vissi. Mazonakis’ funeral is scheduled for September 14 in Nikaia. ## Claims - Mazonakis collapsed while at a medical office in Kolonaki (disputed by 13 sources) - Unannounced inspections by the Athens Medical Association found no plasmapheresis machine at the clinic.
