 I know not who shot the president, but the man who ran across stage was Wilkes Booth. We knew within half an hour that John Wilkes Booth was the assassin. Subsequent to that, I talked to Mr. Ferguson, who had been sitting just here. Ferguson owned the Greenback Saloon on this side of Ford's Theater. He told me he had frequently seen Booth associating with Davey Harrell, Louis Payne, George Atzerodt, and John Surratt. Shortly thereafter, we learned that this was a much larger conspiracy.
