Investigation into the death of singer Giorgos Mazonakis continues as thousands attend his funeral

Popular Greek singer Giorgos Mazonakis died on Wednesday, September 9, 2026, at age 54, following a cardiac arrest during a plasmapheresis procedure at a private clinic in Kolonaki. On Monday, September 14, two doctors, Ilias Theodoropoulos and Ioanna Gaka, appeared before an investigator to face charges of fatal exposure. Authorities are currently examining digital evidence from the medical equipment, which reportedly shows the machine alarms triggering at 15:15, and discrepancies in the doctors' testimonies regarding the timeline of events.

While the medical examiner has labeled the cause of death as "undetermined" pending toxicology and histology results, the family’s legal counsel has suggested the charge could be upgraded to manslaughter with eventual intent. Forensic analysis suggests the device stopped functioning between 15:23 and 15:27, noting a two-hour period of inactivity on the doctors' phones following the event, which investigators describe as a possible attempt to cover up the incident.

Simultaneously, a massive public mourning took place in Nikaia, the singer’s birthplace, where thousands of fans and fellow artists gathered at the Holy Trinity Church for his funeral service. The proceedings, which included an overnight wake, concluded with the final ceremony at 13:00 on Monday, followed by his burial at the Third Cemetery of Athens in a private ceremony.
