A German doctor was jailed on Wednesday, July 8th for the murder of 15 of his patients—and remains under suspicion of killing more of them. He murdered 12 women and 3 men between September 2021 and July 2024.
Previously, it was reported on July 14, 2025, that “Johannes M.” was on trial accused of killing 15 patients with lethal injections and acting as “master of life and death” over those in his care.
The doctor was accused of injecting 15 victims, aged between 25 and 94, with deadly cocktails of sedatives and, in some cases, setting fire to their homes in a bid to cover up his crimes.
The accused had “visited his patients under the pretext of providing medical care,” prosecutor Philipp Meyhoefer said at the opening of the trial at the state court in Berlin. Johannes M. had organised “home visits, already with the intention of killing” and exploited his patients’ trust in him as a doctor, Meyhoefer said.
He was arrested in August 2024, with prosecutors initially linking him to four deaths.
A further 96 cases were still being investigated, a prosecution spokesman told AFP in 2025, including the death of Johannes M.’s mother-in-law. In five cases, Johannes M. allegedly set fire to the victims’ apartments after administering the injections.
