WINONA, Minn. — The state’s chief public defender, Cathryn Middlebrook, has begun an appeal process on behalf of Adam Fravel of Winona, who was convicted in November of murdering Maddi Kingsbury. The appeal will go to the Minnesota Supreme Court. This is a routine process in all first-degree murder convictions. The Court looks for procedural errors in the trial and could order a new trial. This happens rarely. Middlebrook began the appeal process by asking Winona Judge Nancy Buytendorp, who presided in the case, for documents and exhibits from the trial.
