Greek investigators probe delayed ambulance call and alleged malpractice in celebrity’s stem-cell death

A criminal investigation has been opened after singer Γιώργος Μαζωνάκης collapsed and died during a stem-cell therapy session at a Kolonaki clinic. The clinic’s owner claimed the CD34+ treatment using the Smart M-Cell 2 device was a divine health gift, citing dozens of patient testimonies of dramatic improvement. Complaints describe the centre’s doctors rejecting conventional medicine, charging thousands of euros for unproven regimens, and even misdiagnosing a patient’s cancer.

Device logs indicate it was active for 42 minutes, yet the emergency service EKAB was not summoned until 16:23, raising questions about the doctors’ prolonged solo response. The Medical Association of Athens contested the doctors’ timeline, suggesting the procedure should have taken only about 20 minutes. Police are also retrieving erased phone photos and other digital evidence to pinpoint when critical events occurred. The case could lead to upgraded charges, potentially from negligent homicide to murder with intent.
