In Logan Lucky , the rioting inmates start a fire .
FBI agent Sarah Grayson investigates the heist , but due to the unwillingness of the prison authorities to disclose the riot and the extent of a fire set by the rioting inmates and the refuting of Chilblain 's eyewitness account by White ( disgruntled as he crashed during the Coca-Cola 600 due to his drinking some of Chilblain 's energy drink as part of the sponsorship deal ) as well as the Speedway administration 's satisfaction with their insurance settlement , the case is closed after six months .
