An Italian nurse has been bumping off patients she found annoying. Oh and she had also been killing patients whose relis were annoying too. The nasty nurse was caught after potassium was found in one of her victims. After further investigation they discovered 38 patients under her care had died . One of her work mates said the nurse was basically a cold hearted bitch recalling how she had once given a patient a powerful laxative at the end of one of her shifts to give the other nurses an enormous mess to clean up .
