When did Powell's description get reported?

[Susan Higginbotham]

I have a question: when did the description of Seward's unnamed assailant ("inclined to tenor") first get reported? Weichmann claims that it appeared in a dispatch from Stanton and that it was in the April 15 Morning Chronicle that he read at breakfast before he and Holohan went to police headquarters, and that he was much relieved to see that the description didn't match that of John Surratt. The third edition of the Chronicle, however, doesn't contain a description of Seward's assailant, unless I'm simply overlooking it, which as I share Mrs. Surratt's poor eyesight is entirely possible:

A report on page 2 written at 5 a.m. indicates that it was not yet clear whether Booth had also been Seward's assailant.

So is Weichmann's memory playing tricks with him, or was there a dispatch from Stanton that might have appeared in the first or second editions of the Chronicle that was stripped from the third?
