On shore guilt was immediately placed upon a certain white man by several Negro witnesses who demanded that he be arrested by a white policeman who was on the spot. No arrest was made.

The tragedy was sensed by the battling crowd and, awed by it, they gathered on the beach. For an hour both whites and Negroes dived for the boy without results. Awe gave way to excited whispers. "They" said he was stoned to death. The report circulated through the crowd that the police officer had refused to arrest the murderer. The Negroes in the crowd began to mass dangerously. At this crucial point the accused policeman arrested a Negro on a white man's complaint. Negroes mobbed the white officer, and the riot was under way.

One version of the quarrel which resulted in the drowning of Williams was given by the state's attorney, who declared that it arose among white and Negro gamblers over a craps game on the shore, "virtually under the protection of the police officer on the beat." Eyewitnesses to the stone-throwing clash appearing before the coroner's jury saw no gambling, but said it might have been going on, but if so, was not visible from the water's edge. The crowd undoubtedly included, as the grand jury declared, "hoodlums, gamblers, and thugs," but it also included law-abiding citizens, white and Negro.

This charge, that the first riot clash started among gamblers who were under the protection of the police officer, and also the charge that the policeman refused to arrest the stone-thrower were vigorously denied by the police. The policeman's star was taken from him, but after a hearing before the Civil Service Commission it was returned, thus officially vindicating him.

The two facts, the drowning and the refusal to arrest, or widely circulated reports of such refusal, must be considered together as marking the inception of the riot. Testimony of a captain of police shows that first reports from the lake after the drowning indicated that the situation was calming down. White men had shown a not altogether hostile feeling for the Negroes by assisting in diving for the body of the boy. Furthermore a clash started on this isolated spot could not be augmented by outsiders rushing in. There was every possibility that the clash, without the further stimulus of reports of the policeman's conduct, would have quieted down.

Chronological story of the riot.—After the drowning of Williams, it was two hours before any further fatalities occurred. Reports of the drowning and of the alleged conduct of the policeman spread out into the neighborhood. The Negro crowd from the beach gathered at the foot of Twenty-ninth Street. As it became more and more excited, a group of officers was called by the policeman who had been at the beach. James Crawford, a Negro, fired into the group of officers and was himself shot and killed by a Negro policeman who had been sent to help restore order.

During the remainder of the afternoon of July 27, many distorted rumors circulated swiftly throughout the South Side. The Negro crowd from Twenty-ninth Street got into action, and white men who came in contact with it were beaten. In all, four white men were beaten, five were stabbed, and one was shot. As the rumors spread, new crowds gathered, mobs sprang into activity spontaneously, and gangs began to take part in the lawlessness.

Farther to the west, as darkness came on, white gangsters became active. Negroes in white districts suffered severely at their hands. From 9:00 p.m. until 3:00 a.m. twenty-seven Negroes were beaten, seven were stabbed, and four were shot.

Few clashes occurred on Monday morning. People of both races went to work as usual and even continued to work side by side, as customary, without signs of violence. But as the afternoon wore on, white men and boys living between the Stock Yards and the "Black Belt" sought malicious amusement in directing mob violence against Negro workers returning home.

Street-car routes, especially transfer points, were thronged with white people of all ages. Trolleys were pulled from wires and the cars brought under the control of mob leaders. Negro passengers were dragged to the street, beaten, and kicked. The police were apparently powerless to cope with these numerous assaults. Four Negro men and one white assailant were killed, and thirty Negro men were severely beaten in the street-car clashes.
