In this episode, we dive into the tragic murder of Mary Bernice Lange, a mother of three and respected clerk with the Burlington, Iowa Municipal Court. We review the timeline of her last known movements, discuss the evidence in the case, and discuss her relationships.
Despite investigators at the time indicating they had a clear suspect who could be arrested at any time, Mary’s murder remains unsolved to this day.
