Samuel Greenhill and David Dewberry were arrested and charged with the killing of Harry S. White, a guard at a federal nitrate facility in Muscle Shoals, Alabama. The killing of the white guard by the two Black men occurred on December 8, 1923, after White put the men in custody for hunting on federal property.
Dewberry was convicted and sentenced to life imprisonment while Greenhill, determined to have fired the fatal shot, received a death sentence. After President Coolidge refused to intervene in the case, Greenhill was hanged in Florence, Alabama, on October 10, 1925.
