BERLIN — German officials expect to bring new charges against a nurse already serving a life sentence for two murders after determining that he might have killed another 84 patients, if not more, a prosecutor said Tuesday.
Oldenburg state prosecutor Martin Koziolek said he expected his office would be bringing more charges by early 2018 against inmate Niels Hoegel, who gave patients overdoses of heart medication and other drugs because he enjoyed the feeling of being able to resuscitate them.
Additional convictions could affect Hoegel’s possibility of parole, but there are no consecutive sentences in Germany. More than that, bringing additional cases to trial would help determine exactly what happened in those killings and provide some closure for families, Koziolek said.
‘‘These were not all terminally ill people,’’ he said. ‘‘Many were on their way to recovery.’’
He declined to give the ages of the victims or any other details about them, citing German privacy regulations.
Hoegel, now 40, was convicted in 2015 of two murders and two attempted murders at a hospital in the northwestern town of Delmenhorst and was sentenced to life in prison.
