What Was The Role of David Herold

[RJNorton]

Thanks, Clarence. I think it's hard to pin down all of Herold's whereabouts on the day of the assassination. He says he wasn't even in Washington when Booth assassinated the President. As far as I can tell only two people from the conspiracy trial testified they saw Herold in Washington on April 14th. These men were John Fletcher and Silas Cobb. Can anyone think of other eyewitness accounts of Herold's activities in Washington on April 14th?
