Movie to be made about Katherine Knight who killed her husband and cooked him!!

There is a really disturbing story that came from Australia.  Australian Katherine Knight. She was a wife and stepmother but she also brutally murdered her husband, then she went on to mutilate and cook his body. When police arrived to investigate reports, they found John Price’s decapitated corpse, his skin drying in another room, and his head cooking in a pot of stew. Additionally, parts of his ass had been sliced and cooked with vegetables—a meal she intended to serve to Price’s children! She was then sentenced to life in prison for her crimes in 2001. 
Filmmakers Dane Millerd and Ross Murray are working towards turning Knight’s story into a feature film; they’ve acquired the rights to the book Blood Stain by journalist Peter Lalor, which will serve as the script as well.
