A former nurse, Ulrich S., has been sentenced to life in prison for the murders of ten patients and attempted murders of twenty-seven others. Authorities are now investigating over 120 suspicious cases linked to the 45-year-old, who worked at the Rhein-Maas Hospital in Würselen. S. is suspected of administering lethal drug cocktails to ill patients instead of providing appropriate medical care. The investigations are being conducted in Aachen and Köln, expanding the scope of the original case. He was convicted in November 2025. The extent of his crimes has raised serious concerns about patient safety and oversight within the German healthcare system. Authorities continue to probe potential involvement in additional deaths and endangerments.
