Where was John Surratt on April 14, 1865 ?

[RJNorton]

In his book on John Surratt, Andy Jampoler writes, "Passing 140 years later, the answer to the key question - where Surratt was the night Lincoln was shot - is not more certain than it was in 1867, although the defense's witnesses from Elmira sound persuasive today." I would say the same for some of the prosecution witnesses.
