The trio were also suspected of robbing banks in the Minnesota towns of Chandler, Ihlen, Madison, Russell and Westbrook and the South Dakota towns of Canova, Vermillion, Kaylor and Huron. However, events in later years made clear that the trio could not have been responsible for those other bank robberies. Mildred insisted she was framed for the Okabena robbery until she was released from Shakopee Women's Prison in 1942 and two officers of the Sioux City, Iowa police department at that time were watching her at her residence on the day of the robbery. Tony and Floyd also maintained their innocence until they were released from Stillwater Penitentiary in 1946.
