A nurse convicted in the past for murdering two patients is now being investigated by German authorities on suspicion of killing dozens of other patients.
Niels H was charged in 2015 for the murders of two people along with two attempted murders at a clinic in the north-western town of Delmenhorst - though prosecutors have long presumed he killed more people and put the figure to 43 at least previous year.
After exhuming and examining more bodies, police said on Monday, August 28, 2017, that more evidence of murders has been discovered.
Police say the number of victims may be even higher but the final number may never be known as some possible victims were cremated. More than 130 bodies have been exhumed and tested for the presence of the medication, per Agence France-Presse.
Five drugs used were ajmaline, sotalol, lidocaine, amiodarone and calcium chloride, police said.
A chief police investigator in the case, Arne Schmidt said that this is the unique death toll in the history of German Republic.More news: Carnival Cruise Ship Stays Overnight in Cozumel Due to Hurricane Harvey

"Eighty-four killings. leave us speechless", Mr Kuehme said.
In past hearings, Niels H. conceded intentionally infusing patients at two facilities in northern Germany with savage medications and after that endeavoring to restore them so as to play the legend, German telecaster NDR said.
An Oldenburg court sentenced H to life in prison in February 2015 on two counts of murder, two counts of attempted murder and causing bodily harm to patients.
According to police, Hogel would inject patients with a cardiovascular drug to bring on medical emergencies that would then require him to resuscitate them.
Prosecutor Daniela Schiereck-Bohlemann claimed that Hoegel admitted to 30 cases in which he killed patients, AFP said. "People at the clinic in Oldenburg knew of the abnormalities". The minimum estimates indicate at least 90 murders, but police said that it can also be twice that figure.
