A Man On The South Side Of The Capitol

[RobertLC]

In his book, The Assassination of Abraham Lincoln, Osborn H. Oldroyd notes that as Booth headed to the Navy Yard Bridge he was seen by a man on the south side of the Capitol Building. I have included a copy of the page from his book with a highlight of that sentence.

What do we know about this man? Did he submit a letter of evidence before the trial? Did he provide an affidavit? Did he testify at the trial of the conspirators? I have read a similar account someplace, but can’t remember where. As I have searched for additional information about this man, I have not had much success. Maybe I’ve missed it.

Any help for this old inquiring mind will be greatly appreciated.
