FOREST COUNTY, Wis. (WTAQ) - A live-in boyfriend has been charged with the murder of an Eau Claire County woman. 44-year-old Gregory Gubernot was arrested Friday in Forest County, after a warrant was issued. He’s charged with first-degree intentional homicide in the killing of 43-year-old Theresa Still of Altoona. Authorities said she was beaten and strangled, and her body was found 9 days ago in a remote part of Adams County. She disappeared from a tavern in Altoona December 27th after an argument with Gubernot. Prosecutors said Still wanted Gubernot to move out of their house, but he said no. She apparently told a co-worker that Gubernot had gotten, “more and more violent and belligerent” with her.
