When questioned by the detective who took him to jail, Guiteau declared, "I am a Stalwart of the Stalwarts; I did it to save the Republican party." "Is there anybody else with you in this matter?" "Not a living soul," he replied. "I have contemplated the thing for the last six weeks and would have shot the President when he went away with Mrs. Garfield, but I looked at her, and she looked so sick, I changed my mind." After a careful investigation of the facts, District-Attorney Corkhill published the following statement:-- "The interest felt by the public in the details of the assassination, and the many stories published, justify me in stating that the following is a correct and accurate statement concerning the points to which reference is made: The assassin, Charles Guiteau, came to Washington city on Sunday evening, March 6th, 1881, and stopped at the Ebbitt House, remaining only one day. He then secured a room in another part of the city, and had boarded and roomed at various places, the full details of which I have. On Wednesday, May 18th, 1881, the assassin determined to murder the President. He had neither money nor pistol at the time. About the last of May he went into O'Meara's store, corner of Fifteenth and F Streets, this city, and examined some pistols, asking for the largest calibre. He was shown two similar in calibre, and only different in the price. On Wednesday, June 8th, he purchased a pistol, for which he paid $10, he having, in the mean time, borrowed $15 of a gentleman in this city, on the plea that he wanted to pay his board bill. On the same evening, about seven o'clock, he took the pistol and went to the foot of Seventeenth Street, and practised firing at a board, firing ten shots. He then returned to his boarding-place and wiped the pistol dry, and wrapped it in his coat, and waited his opportunity. On Sunday morning, June 15th, he was sitting in Lafayette Park, and saw the President leave for the Christian Church on Vermont Avenue, and he at once returned to his room, obtained his pistol, put it in his pocket, and followed the President to church. He entered the church, but found he could not kill him there without danger of killing some one else. He noticed that the President sat near a window. After church he made an examination of the window, and found he could reach it without any trouble, and that from this point he could shoot the President through the head without killing any one else. The following Wednesday he went to the church, examined the location and the window, and became satisfied he could accomplish his purpose. He determined to make the attempt at the church the following Sunday. Learning from the papers that the President would leave the city on Saturday, the 18th of June, with Mrs. Garfield, for Long Branch, he therefore decided to meet him at the depot. He left his boarding-place about 5 o'clock Saturday morning, June 18th, and went down to the river at the foot of Seventeenth Street,
