This is a biography of the woman who made a career of crime. With a lust for danger, she masterminded the crimes that took her and her husband, and others who included her own mother and stepfather, on a spree across Minnesota, Tennessee, Oklahoma, and Texas. Starting with smaller crimes that included bootlegging, smuggling liquor onto an Oklahoma Indian reservation, and other petty crimes, she encouraged her husband, George Barnes aka George Kelly, toward a life of more serious criminal activity that eventually escalated into bank robberies, kidnapping and extortion. Many believe that it was Kathryn, after giving him a machine gun, who developed George’s feared persona and the name of Machine Gun Kelly. FBI Director J Edgar Hoover was even convinced that the two were somehow connected in the Lindbergh kidnapping.
