New details are continuing to emerge in the investigation into the death of Greek singer Giorgos Mazonakis, with authorities examining the contacts and communications of people around the 56-year-old artist before he underwent the plasmapheresis procedure that preceded his death.
According to a report by MEGA’s Live News, investigators are focusing on a meeting Mazonakis had with a hypnotherapist two days before he was found dead, as well as subsequent communications between the hypnotherapist and one of the two physicians now in pretrial detention.
The two reportedly tried to persuade Mazonakis to undergo the procedure after he had begun expressing reservations and was considering having plasmapheresis performed abroad. In text messages, the physician reportedly wrote that Mazonakis did not want to undergo the procedure, while the hypnotherapist responded that he would “take care of it” and persuade him.
The hypnotherapist has also confirmed that he sent a message to the latter on the afternoon of the procedure saying, “I got you into this,” according to the report.
Authorities are examining communications between the physician and hypnotherapist, including a message containing a photograph of Mazonakis that was reportedly sent to the 62-year-old hypnotherapist’s phone at 2:44 p.m.
The investigation has also brought to light a September 2025 contract between the two doctors and the hypnotherapist, documenting a relationship that reportedly dates back more than a decade. Under the agreement, the hypnotherapist provided specialized services to the doctors’ patients as part of what were described as “holistic treatment plans.” Sessions were conducted at the latter’s offices, including the practice in the Kolonaki district, where emergency responders were called in an attempt to treat Mazonakis.
The agreement reportedly provided for a payment of 40 euros per client, while patients could be charged up to 350 euros per session.
Investigators are also examining the testimony of a 28-year-old secretary at the practice. She has given two preliminary statements and was questioned again by the investigating magistrate following a request from the defense of the two detained doctors.
According to her testimony, one of the two, aged 58, was not in the room with Mazonakis during the critical minutes. She reportedly said he was asleep on a couch at about 3:30 p.m., subsequently dealt with a scheduled patient appointment and issued a referral at 4:05 p.m. She said he was informed of Mazonakis’ condition at about 4:10 p.m. The secretary was also the person who called the emergency medical service.
The investigation is also examining a response from the Athens Medical Association to prosecutors concerning complaints about inspections at the Karneadou Street practice. According to MEGA, the association said inspections had been conducted, but equipment used for plasmapheresis was discovered only after Mazonakis’ death.
Meanwhile, toxicological and histological examinations are expected to provide key evidence. Results are reportedly expected within a month and will examine, among other issues, whether the 56-year-old had been sedated during the procedure, his physical condition and the cause of death.
Police are also awaiting authorization to lift telecoms confidentiality. Investigators are expected to examine phone calls, deleted messages, social media communications and emails involving not only the two detained doctors but also employees at the Karneadou Street practice.
The findings are expected to clarify the contacts and events preceding Mazonakis’ death and whether the plasmapheresis procedure was connected to his death.
