It has been more than a month since much-loved teacher Sharon Edwards graced the halls of her school. While her students at Coutts Crossing Public School on the NSW north coast hold on to the hope the mother-of-three will turn up to school again one day, the police focus has shifted to treating the teacher's disappearance as a homicide. Ms Edwards was last seen on March 14, after she caught up with friends at the local Good Intent Hotel. Investigators, including forensic officers and the dog squad, returned to her home in Grafton on Monday with a crime scene warrant.
