Manhunt and riot
On July 24 a crowd of whites gathered on Fourth Street, where the policemen were killed. There were shouts for lynching Charles, but the crowds dispersed when they were falsely told Charles had been located and jailed. On July 25, Acting Mayor Mehle (Mayor Paul Capdevielle was out of town) announced a $250 reward for the arrest of Charles while issuing a proclamation urging peace. New Orleans papers, particularly the Times-Democrat, blamed the black community for Charles’ crimes and calling for action.
In the following days, several riots occurred as mobs of armed whites roamed the streets. On the night of the 25th they killed three blacks and wounded six more so severely they had to be hospitalized. Five whites were also hospitalized, and more than 50 people suffered lesser injuries. Charles had taken refuge at 1208 Saratoga Street, where he remained safe from the police until Friday, July 27.
The house was quickly surrounded by police after they learned that Charles was there. Throughout the day, the police fired on the house, where Charles sporadically returned the fire. By the end of the day, Charles had shot a total of 27 white people in the course of the week, seven fatally; four were policemen.
The police decided to burn down the building to flush out Charles. As he tried to escape, he was shot by Charles A. Noiret, a medical student and member of the special police (a militia police group of volunteer citizens). The policemen continued to shoot Charles. When they dragged his body outside, a mob of bystanders beat his body.
