By Julia Bertino Jun 30, 2021 (Omaha, NE) -- A Norfolk man will spend the rest of his life in prison for his part in the fatal kidnapping of a South Dakota woman. The United States Attorney's Office says on Wednesday, 51 year old Ramon Simpson was sentenced to life in prison for Kidnapping Resulting in Death and Conspiracy to Commit Kidnapping. Federal Judge Brian C. Buescher sentenced Simpson to life imprisonment on each count. Simpson was convicted by a jury in March. Federal prosecutors say Phyllis Hunhoff regularly traveled from her home in Yankton, South Dakota to her mother’s home in Utica, South Dakota. They say her regular practice was to call her mother upon returning to Yankton. On November 4, 2018, Phyllis Hunhoff left her mother’s residence, alone, to drive home to Yankton. Investigators say she didn't call her mother as she did not make it home. Having not heard from Phyllis, her mother began repeatedly calling her phone to determine her whereabouts. All calls were unanswered.
