Easy boy, I wasn't serious about the doppelganger; I was merely trying to highlight the flagrant inconsistency between Demond's letters (especially the one of June 12, 1916) and everything we know from other sources about the movements of Booth and Herold on April 14. Demond, and, later, as you point out, Dana, seem certain of the identity of the two men at the bridge, differing only on time of arrival and time of release. I frankly do not know how to reconcile the accounts. I doubt that anyone is intentionally lying (for what purpose?),so there must be another explanation. If you can offer one, other than the doppelganger theory, I am all ears.

As we have discussed before, Frederick Demond and David Dana are NOT reliable sources due to the huge discrepancies in their later accounts and the heavy influence of Finis Bates on both of them. In this way, there is NO reliable evidence that places John Wilkes Booth in Maryland on the morning of April 14th.
