In brief
The 41‑year‑old German palliative care doctor, Johannes M., was sentenced to life after a Berlin court found him guilty of murdering 12 women and 3 men between 2021 and 2024. The court believes the killings may be just the tip of the iceberg, as prosecutors investigate over 70 other cases. Victims, aged 25 to 94, were critically ill, yet the doctor omitted their consent before administering lethal medication and even tried to cover his tracks with arson. The case raises serious concerns about patient safety in home‑care settings and stresses the importance of stringent oversight in Germany’s health system.
In Berlin, a 41‑year‑old palliative care doctor, Johannes M., has been given a life sentence after a court found him guilty of murdering 12 women and 3 men between September 2021 and July 2024.
Prosecutors say the killings may just be the tip of the iceberg. They’re investigating more than 70 other suspected incidents, potentially making this the largest serial‑murder case in Germany’s history.
The victims, aged 25 to 94, were all critically ill but were not at imminent risk of death. The doctor allegedly administered lethal doses of medication during home visits without the patients’ consent.
In July 2024, he killed two patients in one day – a 75‑year‑old man in central Berlin and a 76‑year‑old woman a few hours later in a neighboring district. He also attempted to set a fire to cover his tracks.
The court imposed a lifetime ban on his medical practice and placed him in preventive detention after sentencing.
Health‑care authorities have called for tightening oversight of home‑care delivery to prevent such tragedies and restore trust in patient‑doctor relationships.
