What happened
Former nurse Niels Högel was convicted of murdering patients at hospitals in Oldenburg and Delmenhorst, making the case one of the largest healthcare serial-murder prosecutions in modern Europe.
The investigation
Suspicion grew after colleagues noticed alarming emergencies during his shifts. Years later, extensive exhumations and record reviews were used to reconstruct a far larger number of suspicious deaths.
What the courts or investigators concluded
In 2019, Högel was convicted of 85 murders and received a life sentence with a finding of particularly severe guilt.
Why the case remains significant
The case triggered major scrutiny of hospital reporting systems and how professional reluctance to escalate concerns can allow dangerous behavior to move between institutions.
