A NURSE serving life in Germany for two murders may have killed more than 100 patients.

Prosecutors and police in the north-western city of Oldenburg said they have completed examinations of patients who died during Niels Hoegel’s time as a nurse at two local hospitals and have found a further 16 cases in which he is suspected.

In August, they said they had determined that he might have killed at least another 84 patients beyond those for which he has been convicted. Prosecutors have said that they expect to bring more charges by early 2018.

Hoegel, 40, was convicted in 2015 of two murders and two attempted murders at a hospital in Delmenhorst.

His trial heard he gave patients overdoses of heart and other drugs because he enjoyed the feeling of being able to resuscitate them. He later told investigators he also killed patients in Oldenburg.

Police have said Hoegel could have been stopped earlier if health officials had not hesitated over alerting the authorities. Criminal cases are being pursued against former staff at the two hospitals.
