Berlin Doctor Convicted of 15 Patient Murders, Court Cites "Serial Killer" Designation

A German palliative care doctor was sentenced to life in prison Wednesday for murdering 15 of his patients with lethal doses of sedatives, Courthouse News Service reports. The Berlin court convicted 41-year-old Johannes M. — only partially identified in court records — of killing 12 women and three men during home visits between September 2021 and July 2024.

Presiding Judge Sylvia Busch described the man as a "serial killer" at the center of an "unfathomable" and "extraordinary" case. Because the court found his crimes carried a "particular gravity of guilt," he received the harshest sentence available under German law, significantly reducing his chances of ever being released. The court also permanently banned him from practicing medicine.

The killings were not driven by compassion or a misguided sense of assisted dying, the court ruled, but by "a drive for power over his victims." Prosecutors had characterized the physician as having "a lust for murder," stating he had "no other motive for killing these people than the act of killing itself."

The victims, all under his medical care at the time, ranged in age from 25 to 94. According to the court's findings, Johannes M. intentionally administered an anesthetic and a muscle relaxant that "paralyzed the respiratory muscles, leading to respiratory arrest and death within minutes." On at least five occasions, he allegedly set fire to victims' apartments in an attempt to destroy evidence.

On Monday, ahead of sentencing, Johannes M. confessed that he had "killed people" and told the court, "I despair at myself." He said he only now understood "the extent of the suffering" he had caused, according to the Frankfurter Allgemeine Zeitung.

Among the documented killings, the court detailed a single day — July 8, 2024 — on which he killed two patients. That morning, he killed a 75-year-old man at his home in Berlin's Kreuzberg district. Within hours, he killed a 76-year-old woman in the neighboring Neukölln district. His attempt to burn down the second crime scene failed when the fire did not catch, prosecutors said.

Judge Busch acknowledged that the conviction for 15 murders may represent only a fraction of his crimes. During the proceedings, prosecutors said Johannes M. is suspected of having killed more than 70 additional people. He was detained in 2024 after care services first raised suspicions about his activities, prompting a police investigation. Initially, investigators examined four cases; the number of suspicious deaths grew steadily from there, with further cases still under review. He was remanded in custody in August 2024.

The case draws comparisons to that of German nurse Niels Hoegel, sentenced to life in prison in 2019 for the murder of 85 patients. In a separate, more recent case, a palliative care nurse was also sentenced to life in November for the murder of 10 patients and the attempted murder of 27 others through lethal injections.
