The male nurse convicted of murdering two patients in a clinic and who is suspected by investigators of having killed 84 more is said to be a hero in prison as he boasts about his accomplishments. German nurse Niels Hoegel, 40, was sentenced to life imprisonment for two murders, two counts of attempted murder and one count of serious bodily harm two years ago at the Oldenburg Regional Court in Germany’s north-western state of Lower Saxony.
