"US Park Police Officer Kennedy was on foot patrol in Logan Circle when he was knocked unconscious by a thrown brick. Then a mob of 21 descended and beat Officer Kennedy to death with feet, fists, and his own night stick. Nine suspects were indicted for his murder. Of those nine, three were never apprehended, three were acquitted, and the other three were sentenced to death. All three were executed by electrocution in the District Jail on January 12, 1934."
