An Eau Claire County judge has signed off on an order dismissing murder charges against a man accused of killing his sister.  Investigators say 75-year-old James Bonczkowski strangled and stabbed his sister at her rural Augusta home in October 2016.  When authorities found her body, they say a knitting needle was sticking out of the dead woman’s chest.  It was determined that Bonczkowski wasn’t competent to stand trial last year.  He has Alzheimer’s disease and has suffered strokes and brain bleeds.  Doctors have told the court he will never regain competency, so the murder charge was dismissed.
