Where was John Surratt on April 14, 1865 ?

[RJNorton]

Kees, as far as I can tell, Atzerodt does not say he saw Surratt in Washington on April 14 in his July 6, 1865, statement (the one in Weichmann's book). He says that Booth told him that he (Booth) saw Surratt; he does not say he (Atzerodt) saw Surratt. Nevertheless, I find this curious. Why would Booth say this?

It seems to me there are at least four possibilities regarding what Atzerodt wrote that night: (1) Surratt really was in DC; (2) Booth was lying; (3) Atzerodt was lying; (4) Atzerodt misheard what Booth told him.
