Greek singer Yorgos Mazonakis died at age 54 on Sept. 9, 2026, following a plasma exchange treatment at a private medical office in Athens’ Kolonaki district, prompting a criminal homicide investigation. Investigators analyzing the case have uncovered evidence that the treating physician allegedly searched ChatGPT for resuscitation instructions after the musician lost consciousness, according to reporting cited by Greek television channel MEGA and Greek City Times.
Criminal Investigation and Arrest of Clinic Operators
The day after the singer’s death, authorities arrested married doctors Dr. Ioanna Gaka and Dr. Ilias Theodoropoulos, who operated the clinic. The facility is registered under Theodoropoulos’s name, while investigators state that Gaka treated Mazonakis. Prosecutors initially opened a case for abandonment resulting in death before upgrading the charges to suspected intentional homicide following a review of digital evidence. Both doctors deny wrongdoing and remain in custody pending trial. Greek Health Minister Adonis Georgiadis stated that the facility was registered as a standard medical office rather than a medical center, and lacked authorization to perform plasma exchange treatments. Police and representatives of the Athens Medical Association subsequently discovered two plasmapheresis machines at the location, though the doctors’ legal counsel has disputed claims that the equipment was undeclared or operated illegally.
Timeline of Treatment and Digital Evidence
Data recovered from the plasmapheresis machine reveals that Mazonakis was connected to the device at approximately 2:14 p.m. on Sept. 9, 2026. The machine recorded its first alert at 2:25 p.m., with blood flow beginning at 2:37 p.m. Investigators suspect that at 2:44 and 2:45 p.m., Gaka photographed the unconscious singer and transmitted the image to an acquaintance, a detail corroborated by Live News reporting cited by Greek City Times. The device stopped operating at 3:22 p.m., yet records indicate Mazonakis remained hooked up for another 23 minutes. Additional alerts occurred at 3:45 p.m., and resuscitation efforts reportedly did not begin until after that point. The national emergency service EKAB was not summoned until approximately 4:21 p.m. Gaka has disputed the prosecution timeline, asserting that Mazonakis’s condition only worsened after 4 p.m., that machine alerts indicated issues with veins and catheters rather than cardiac distress, and that ambulance crews mishandled the evacuation.
Medical Risks of Plasmapheresis and Patient Complaints
Plasmapheresis removes the liquid portion of blood and replaces it with donor plasma or another fluid, a procedure utilized in hospitals for severe conditions such as TTP, Guillain-Barré syndrome, and myasthenia gravis. Dr. Albert Kolomensky of Assuta Ashdod Hospital noted that while the procedure is established when medically indicated, it can trigger dangerous drops in blood pressure, electrolyte shifts, and heart rhythm disturbances, requiring an approved medical setting and trained personnel. Alongside the criminal probe into Mazonakis’s death, former patients of the clinic told Live News that they paid high fees ranging from €200 to €400 per visit for unusual treatments, including full-body scans and alternative therapies. Authorities are examining whether the practitioners operated outside their medical specialties and financially exploited patients as the investigation continues.
