The Oldenburg court on Thursday sentenced 42-year-old Niels Hoegel to life in prison and noted the "particular seriousness of the crimes" to ensure he serves beyond the standard 15-year term, the dpa news agency reported.
The killings took place while Hoegel worked at a nurse at two hospitals in northwestern Germany from 2000 to 2005. In all Hoegel was charged with 100 counts of murder and it was not immediately clear why the court only found him guilty on 85 counts.
Hoegel apologized in a closing statement at the end of the seven-month trial.
A verdict is expected in the case of a former nurse charged with 100 counts of murder on allegations he killed patients by putting them into cardiac arrest because he liked the feeling of being to resuscitate them.
The 42-year-old Niels Hoegel faces possible life in prison if convicted Thursday of the killings at two hospitals in northwestern Germany from 1999 to 2005.
Prosecutors are asking the court in Oldenburg to recognize the "particular seriousness of the crimes" to ensure he serves beyond the standard 15-year term.
During the seven-month trial, Hoegel admitted to 43 of the killings, disputed five, and said he couldn't remember the other 52.
Hoegel expressed regret in a closing statement Wednesday, saying he realized how much pain and suffering he'd caused with his "terrible deeds."
