German doctor convicted of killing 15 patients but he likely killed many more.

The lethal poison drug combination was the same as used for euthanasia.

Bethany Bell reported for BBC news on July 8, 2026 that a German doctor was sentenced to life imprisonment for killing at least 15 patients.

Bell reported that:

A court in Berlin found the 41-year-old man, named only as Johannes M. in line with German privacy rules, guilty of murdering 12 women and 3 men between September 2021 and July 2024.

The authorities believe these killings could be just the tip of the iceberg. Prosecutors are currently investigating dozens of other incidents involving the doctor.

His victims were between the ages of 25 and 94. The court heard how they were all critically ill, but that their deaths were not imminent.

Prosecutors said that during home visits, the doctor administered a lethal combination of various medicines without his patients' consent.

On several occasions, they said he set fires to cover his tracks.

In July 2024, shortly before his arrest, prosecutors said the doctor killed two patients in a single day - a 75-year-old man at his home in central Berlin and, a few hours later, a 76-year-old woman in a neighbouring district.

They said the doctor tried to set fire to the woman's house, but failed. 

CBS News reported on July 8 that:

Presiding judge Sylvia Busch said the conviction for 15 murders may well be only a glimpse of his many crimes.

Prosecutors said during the proceedings that he was suspected of having killed more than 70 other people.

An article by Emily Atkinson that was published by the BBC on April 16, 2025, suggests that he used the similar drugs as are used for euthanasia:

He is accused of administering an anaesthetic and a muscle relaxant to his patients without their knowledge or consent.

The relaxant "paralysed the respiratory muscles, leading to respiratory arrest and death within minutes", the prosecutor's office said in a statement.

Based on the way he killed his patients, they appear to have died in the same way as a euthanasia death. It is likely that the physician was trained by a euthanasia group. 

In 2019, Niels Högel, a nurse in Oldenburg, Germany, was convicted of murdering 85 patients from 2000 to 2005, and investigators suspect the true number of victims was far higher. Mr. Högel was found to have administered drug overdoses that caused cardiac arrest so that he could revive the patients and be celebrated as a hero.

Cases of medical homicide are not uncommon. Medical practitioners who have been convicted of murdering patients, include: Dr. Harold Shipman, Charles Cullen, Dr Virginia Soares de Souza, Aino Nykopp-Koski and Dr. Michael Swango.

Professor Christopher Lyon, who teaches at the University of York (UK) published a research paper on August 2, 2024 stating that Canada's (MAiD) euthanasia law enables healthcare serial killers (HSK).

It is not safe to give doctors, or others, the right in law to kill people.

When a nation legalizes euthanasia, it gives medical professionals, who were already killing their patients, the legal right to proceed.
