Berlin court sentences palliative care doctor to life in prison for 15 patient murders
A Berlin court sentenced a 41-year-old palliative care physician to life imprisonment on Wednesday for the murder of 15 patients, with investigators probing 76 additional suspicious deaths.
Sentencing and verdict
The Berlin Regional Court sentenced 41-year-old palliative care physician Johannes M. to life imprisonment on Wednesday, the maximum penalty under German law. The court also imposed a lifetime ban on practicing medicine. Presiding judge Sylvia Busch described the defendant as a "serial killer" and said the 15 proven murders were likely "just the tip of the iceberg."
Patients put themselves in his hands, and he had the power over life and death. The patients wanted to live.
The crimes
Between September 2021 and July 2024, Johannes M. administered lethal drug cocktails to 12 women and 3 men aged 25 to 94 during home visits. The mixture combined a sedative with a muscle relaxant, causing respiratory paralysis and death within minutes. All victims were seriously ill but not imminently dying. In at least five cases, he set fire to the victims' apartments to cover up the homicides.
These acts have nothing to do with palliative care or euthanasia.
Investigation and arrest
The case came to light in July 2024 when a supervisor at a Berlin home care service noticed an unusual pattern: many of Johannes M.'s patients had died suddenly, and several apartments were on fire at the time of death. He was arrested in early August 2024, initially on suspicion of four murders, and has been in pre-trial detention since. The list of alleged victims grew to eight by November, ten by February 2025, and fifteen by April 2025. Prosecutors, who said the defendant appeared to have no motive beyond the act of killing itself, are now investigating 76 additional deaths and plan to file further charges. The defendant has indicated he will cooperate with the ongoing investigations.

Defendant's confession and background
On 25 June 2026, Johannes M. admitted in court to killing 12 of the 15 patients. "Only now am I able to explain my actions and I take responsibility for them," he said. The judge noted that in a phone conversation with his wife, the doctor said he had been killing for a long time. German media reported that he studied homicides as part of his doctoral thesis in medicine, completed in February 2013 at age 28.
A pattern of healthcare killings
The case echoes that of former nurse Niels Högel, who was convicted in 2019 of murdering at least 85 patients in two hospitals in Lower Saxony. Högel, diagnosed with a severe narcissistic personality disorder, remains Germany's most prolific serial killer. If the additional 76 deaths are linked to Johannes M., he would surpass that record.
