Giorgos Mazonakis Death: Two Doctors Face Prosecutor as Investigation Focuses on Missing Hours and Plasmapheresis

Two doctors arrested in connection with the death of popular Greek singer Giorgos Mazonakis are expected to appear before a prosecutor on Friday as investigators examine a series of contradictions surrounding his final hours at a private clinic in Athens.

Doctors Ioanna Gaka and Elias Theodoropoulos face a case concerning alleged fatal exposure following the singer’s death after suffering a cardiac arrest at the Kolonaki clinic.

Police are examining security camera footage, statements from those present at the clinic, data from a plasmapheresis machine, the legality of the medical equipment and a large volume of digital evidence seized during a search of the premises.

A post-mortem examination is also expected to take place on Friday in the presence of a technical adviser appointed by Mazonakis’ family.

The three-hour gap investigators are trying to explain

One of the central questions concerns the time Mazonakis arrived at the clinic on Karneadou Street.

According to information cited in the investigation, one of the doctors reportedly told police that the singer arrived at around 4:30pm after being delayed for his appointment.

However, security camera footage reportedly places Mazonakis at the clinic shortly after 1:00pm, potentially creating a gap of around three hours.

The emergency call was made shortly after 4:20pm.

Investigators are now attempting to reconstruct the singer’s movements minute by minute, from his arrival at the clinic until his collapse and the subsequent emergency response.

The discrepancy has become one of the key elements in the investigation.

What happened with the plasmapheresis treatment?

Investigators are also examining whether plasmapheresis had already begun when Mazonakis suffered the cardiac arrest.

According to the account attributed to the doctor, the treatment had not actually started and the singer collapsed while intravenous lines were being inserted.

She reportedly said that his blood pressure dropped sharply while a second intravenous catheter was being placed in his left arm.

However, statements attributed to emergency responders reportedly indicate that the plasmapheresis machine was already operating when they arrived.

Police have also examined the machine’s technical data. According to the information reported, its previous recorded operation lasted approximately 45 minutes.

Further examination of the equipment is expected to establish exactly when it was switched on and under what conditions it was operating.

Investigators are seeking to determine what medical procedure was being carried out, how far it had progressed, who was present and what happened immediately before and after Mazonakis collapsed.

The bandage on his head and reported fall

Another detail under investigation is a bandage reportedly found on Mazonakis’ head when he was at the clinic.

According to statements attributed to the doctor and an employee, Mazonakis had reportedly told them that he became dizzy and fell down the stairs while leaving his home.

Investigators are examining the account as part of the wider reconstruction of his condition before the cardiac arrest.

At this stage, there is no established finding that the reported fall was connected to his death.

Two plasmapheresis machines found at the clinic

The legality and licensing of the medical equipment at the clinic has also come under scrutiny.

During a joint inspection by police and a team from the Athens Medical Association, authorities reportedly found two plasmapheresis machines.

According to the information presented in the investigation, the equipment did not appear in the clinic’s registered equipment during inspections carried out in 2024 and 2025.

The Athens Medical Association has reportedly stated that the premises were licensed as an internal medicine clinic and that plasmapheresis could not be performed there under that licence.

The association has also stressed that plasmapheresis is a complex medical procedure that requires an appropriate medical indication, trained personnel and facilities capable of dealing with potentially serious complications.

Specialists questioned about plasmapheresis

Police have sought expert medical evidence to establish the normal requirements and potential risks associated with plasmapheresis.

Investigators reportedly visited the Haematology Clinic at Evangelismos Hospital, where specialists explained the procedure and the conditions under which it is normally carried out.

According to information included in the case file, plasmapheresis requires appropriate certified equipment, two venous access points and appropriately trained and certified medical personnel.

Experts have also highlighted the possibility of haemodynamic instability during the procedure, making the precise circumstances surrounding Mazonakis’ treatment a major focus of the investigation.

Earlier investigation involving anabolic substances

Investigators are also reviewing information from an older case involving the alleged illegal distribution of anabolic substances.

According to reports, prescriptions bearing the name of Ioanna Gaka were allegedly discovered during an earlier investigation into a pharmacy suspected of being involved in the preparation and distribution of anabolic substances.

The material is now being reviewed as part of the wider investigation.

However, there is currently no established evidence linking that earlier case to Mazonakis’ death.

Any connection between the two matters remains subject to investigation.

Police search clinic and doctors’ home

The arrests followed an extensive search of the clinic on Karneadou Street.

Police officers spent several hours examining the premises alongside officials from the Athens Medical Association and specialists from the Hellenic Police forensic investigation division.

Investigators seized documents and digital material, including computers, hard drives and other storage devices, as well as records and substances found at the premises.

The material was transferred to specialist police laboratories for examination.

Particular attention is being paid to the digital evidence, including whether any files or other information may have been deleted or altered after Mazonakis’ death.

Police later searched the home of the two doctors in Psychiko before taking the couple to the Athens Security Directorate in Kypseli for further questioning.

The two doctors were subsequently arrested.

Mazonakis’ family seeks answers

Mazonakis’ family has taken legal action and intends to support the prosecution against the two doctors and anyone else who may be found responsible.

The family’s lawyer, Charalambos Lykoudis, has stressed that the priority is to establish exactly what happened without prejudging responsibility.

The family has also sought further investigative measures, including the lifting of telecommunications privacy restrictions where legally permitted, to clarify the circumstances surrounding the singer’s final hours.

A technical adviser appointed by the family is expected to attend the post-mortem examination.

Post-mortem could provide crucial answers

The post-mortem examination is expected to provide important evidence for investigators.

It was initially scheduled for Thursday but was postponed until Friday, September 11, allowing the family’s technical adviser to attend.

Forensic doctors in Athens are expected to examine Mazonakis’ body as investigators seek definitive answers about the cause of death.

The key questions now include the exact timeline of events, whether plasmapheresis had begun, what medical procedure was being performed, whether the equipment was legally authorised for use at the clinic and whether any medical action can be causally linked to the singer’s death.

The investigation remains ongoing, and the allegations against the two doctors have yet to be tested in court.
