One evening of May, 1856, King published, in the Bulletin, copies of papers procured from New York, to show that Casey had once been sentenced to the State penitentiary at Sing Sing.

Casey took mortal offense, and called at the Bulletin office, on the corner of Montgomery and Merchant Streets, where he found King, and violent words passed between them, resulting in Casey giving King notice that he would shoot him on sight.

King remained in his office till about 5 or 6 p.m., when he started toward his home on Stockton Street, and, as he neared the corner of Washington, Casey approached him from the opposite direction, called to him, and began firing.

King had on a short cloak, and in his breast-pocket a small pistol, which he did not use.

One of Casey's shots struck him high up in the breast, from which he reeled, was caught by some passing friend, and carried into the express-office on the corner, where he was laid on the counter; and a surgeon sent for.
