A husband from Plover has entered a not guilty plea to charges of first-degree intentional homicide and hiding a corpse in his wife’s disappearance. Jason Sypher was in Portage County Circuit Court Monday. Prosecutors accuse him of killing his wife, 44-year-old Krista Sypher, and hiding her body — which still hasn’t been found. He reported her missing in March 2017. The charges were filed against Sypher two months ago.
