James Earl Files (born January 24, 1942), also known as James Sutton, is a former American prisoner. In 1994, while serving a 50 year sentence for the 1991 attempted murders of two police officers, Files gave interviews stating that he was the "grassy knoll shooter" in the 1963 assassination of United States President John F. Kennedy. Files has subsequently been interviewed by others and discussed in various books pertaining to the assassination and related theories. In 1994, the Federal Bureau of Investigation was quoted as having investigated Files' allegation and found it "not to be credible".
