A Ukiah woman arrested for assaulting a police officer has been sentenced to 8 years in prison. This past May, Rachael D. Seivertson, formerly of the Ukiah area, was contacted after complaints. While officers detianed her, she picked up a large rock and hit an officer in the face. Seivertson was arrested. The fact that her behavior has become more erratic over the years and a prior conviction netted a strike enhancement to her conviction.
