The Bulletin of May 14th, in which the charges founded upon the most incontrovertible evidence, of Casey's conviction, sentence and discharge from Sing Sing, was made in the plainest terms accompanied with comments upon his ballot-box stuffings and other criminal acts in San Francisco, was published at an early hour in the after noon. At four o'clock Casey called at the Editor's room and demanded of Mr. King what he meant by the article in the Bulletin just issued, and was asked to what article he alluded? "To that" was the reply, "in which I am said to have been formerly an inmate of Sing Sing State Prison." "Is it not true?" said King. Casey replied, "That is not the question. I don't wish my past acts raked up; on that point I am sensitive." King then pointed to the door which was open, and told him to leave the room and never enter there again. Casey moved to the door saying, "I'll say in my paper what I please." To which King replied "You have a perfect right to do as you please. I shall never notice your paper." Casey said, "If necessary, I shall defend myself." King, rising from his seat, said, "Go, and never show your face here again." Casey immediately retired.

At five o'clock, his usual dinner hour, Mr. King left his office. With his arms crossed under his Taima, as was his wont, and his eyes cast down, he passed along Montgomery Street apparently in deep thought, and at the corner of Washington Street began to cross the street diagonally. When about half across, Casey stepped from behind an Express wagon, dropped a short cloak from his shoulders, and uttering a few words, the only ones heard by Mr. King, as he said on his death bed, being "Come on," immediately discharged one barrel of a large revolver into Mr. King's breast. Mr. King drew himself up, and then made a slight motion sideways, indicating plainly to the few persons in sight at the time, that he was hit. The spectators immediately ran in towards him, and assisted him into and seated him in the Express Office. He was badly wounded in the left breast, and was apparently in a dying condition.

In the meantime Casey was hurried by his friends and the Police to the Station House in the City Hall, and from thence, when the demonstrations of the immense multitude of infuriated citizens became awfully threatening, in a close carriage, to the Prison on Broadway, where, within stone walls, he might, as he did, receive the visits an congratulations of his admirers and the haters of the good man, whom he had slain; and lay his plans for eluding justice as so many before him had done. But he reckoned without his host. His hour had struck. The Avenger was on his trick, never more to lose sight of him till he had forced him to a speedy, public and ignominious death. The People, whom he had so long abused and deprived of their rights, as at last almost to have learned to ignore their very existence, had reached that point at which forbearance had ceased to be a virtue. Through the City darted with the speed of light the intelligence of his crime; and to the scene of it rushed from all the streets, lanes and by ways of the City, with wild haste and fearful imprecations, the thousands upon thousands whom that word of fearful import had filled with sorrow, hate and desperate resolve. Filling every street and avenue in the neighborhood with the innumerable multitude which swayed to and fro like the tempest tossed waves of ocean; the main body continued for hours, loading the air with hoarse murmurs or angry shouts; detachments breaking off from time to time to rush with frantic speed and hurl themselves successively but impotently upon the iron doors and stone walls of the Station House or Jail.

During the evening, so threatening became the demonstrations of the people that every effort was made by the authorities to reinforce the Police. Armed men were dispatched from time to time to be stationed around and on the top of the Jail. They were received, as they made their way through the dense mass with hootings and execrations. The Mayor vainly endeavoured to obtain a hearing, and to calm the fiery passion of the multitude. With wild rage, fruitless clamor and ineffective effort, that great crowd waited impatiently but vainly for some leader to give direction to their energy. At half past eleven a mounted battalion consisting of the California Guards, First Light Dragoons and National Lancers, were mustered, supplied with ammunition, and marched off to the Jail, where they did duty during the night. The safety of the Prison being now provided for, the people quietly dispersed to their homes, not, however, until a Committee, consisting of Messrs. Macondry, Palmer and Sims in whom they had confidence had been sent in, and reported to them that the prisoner was securely locked in a cell within it.

Meantime, amid this wild tumult of the people, a number of merchants and other prominent and influential citizens had assembled in a store in the lower part of the City, and there after full consideration of the intolerable condition of affairs, it was resolved forthwith to organize a Vigilance Committee. At an early hour the next morning another meeting was held and a Constitution adopted, the publication of which was sometime after sanctioned by the Executive Committee.

This Instrument was deliberately approved, and was subscribed by several thousand citizens of San Francisco, who, in action under it, periled life and fair fame. The following extracts from it will show the causes of the movement; and the ability and determination of those who inaugurated and prosecuted it to its final issue:

Whereas it has become apparent to the citizens of San Francisco that there is no security for life or property either under the regulations of society, as it at present exists, or under the laws as now administered, and that by the association of bad characters our ballot boxes have been stolen and others substituted, or stuffed with votes that were never polled, and thereby our elections nullified; our dearest rights violated; and no other method left by which the will of the people can be manifested; therefore, the citizens whose names are hereunto attached, do unite themselves into an association for maintenance of the peace and good order of society; the prevention and punishment of crime; the preservation of our lives and property; and to insure that our ballot boxes shall hereafter express the actual and unforged will of the majority of our citizens; and we do bind ourselves each to the other by a solemn oath to do and perform every just and lawful act for the maintenance of law and order, and to sustain the laws when properly and faithfully administered. But we are determined that no thief, burglar, incendiary, assassin, ballot box stuffer, or other disturber of the peace shall escape punishment, either by the quibbles of the law, the insecurity of prisons, the carelessness or corruption of the police, or the laxity of those who pretend to administer justice; and, to secure the objects of this association, we do hereby agree, that the name and style of the Association shall be "The Committee of Vigilance, for the protection of the ballot box, the lives, liberty, and property of the citizens and residents of the City, of San Francisco."

That there shall be Rooms for the deliberations of the Committee at which there shall be some one or more members of the Committee, appointed for that purpose, in constant attendance at all hours of the day and night to receive the report of any member of the association or of any other person or persons whomsoever of any act of violence done to the person or property of any citizen of San Francisco; and if in the judgment of the member or members of the Committee present, it be such an act as justifies or demands the interference of this Committee, either in aiding in the execution of the laws, or the prompt and summary punishment of the offender; the Committee shall be at once assembled for the purpose of taking such action as a majority of them, when assembled, shall determine upon.

That whereas, an Executive Committee has been chosen by the General Committee, it shall be the duty of the said Executive Committee to deliberate and act upon all important questions and decide upon the measures necessary to carryout the objects for which the association was formed.

That whereas this Committee has been organized into subdivisions; the Executive Committee shall have power to call, when they shall so determine, upon a Board of Delegates, to consist of three representatives from each division to confer with them upon matters of vital importance.
