A German nurse has been convicted of murdering 85 of his patients by overdosing them on drugs.

Niels Hoegel admitted he enjoyed inducing cardiac arrests in his patients because he liked to bring them back from death - but he couldn't always do so.

He is believed to be the most prolific serial killer in Germany's modern history.

The 42-year-old was found guilty on Thursday, and was sentenced to life in prison.

He has already been found guilty of two other murders in a 2015 trial, and is already serving a life sentence, reports CBS News.

Hoegel worked at a hospital in Oldenburg between 1999 and 2002 and another near Delmenhorst from 2003 to 2005. 

After he was convicted of the first two murders, a wider investigation into both hospitals revealed his other victims.

The files of over 500 patients were reviewed and police exhumed 134 bodies from 67 different cemeteries and interviewed, reports CBS News.

Prosecutors found the majority of Hoegel's victims were not terminal, but recovering.

He was tried on 100 counts of murder but found not guilty for 15 of them due to lack of evidence.

He admitted to 43, disputed five and "couldn't remember" 52.

Hoegel apologised to the families of his victims, saying "to each and every one of you I sincerely apologise for all that I have done."
