Herold and Surratt

[SSlater]

I do no have a copy of Surratt's trial. So, I need some help. I have a copy of one page of the "Elmira Morning Telegram" for April 22, 1917, which has a "50th year Anniversary of the Surratt Trial" article, in which they say "It was finally admitted by the prosecution that Surratt was in Elmira on the morning of the 13th." The newspaper then adds that " an effort was made by the prosecution to show that he made a rapid journey to Washington to arrive there for the assassination." which the defense then shredded that ploy to bits.
My question is: Did the prosecution really admit that, during the trial?
