Police fear nurse could have killed at least 84 people
A nurse who was convicted of killing patients in Germany with overdoses of heart medication is now believed to have killed at least 84 people - and the true scale of the killings could be larger, investigators said.
Niels Hoegel was convicted in 2015 of two murders and two attempted murders at a clinic in the north western town of Delmenhorst. But prosecutors believe he killed more, last year putting the figure at 43 at least.
The crimes came to light after Hoegel was convicted of attempted murder in another case.
Oldenburg police chief Johann Kuehme said authorities have now unearthed evidence of 84 killings in addition to the ones for which Hoegel was convicted.
