In 1970, shortly after being elected Attorney General of Alabama, 29-year-old Bill Baxley reopened the 16th Street Church bombing case. The racially motivated act of terrorism, which killed four African-American girls in 1963, resulted in a fruitless investigation and marked a turning point in the Civil Rights Movement.

Fields — founder of the “National States’ Rights Party” and “Grand Dragon” of the New Order Knights of the Ku Klux Klan — in which Baxley was accused of reopening the case to score political points.
