Why was Mary Surratt not photographed after her arrest?

[Dave Taylor]

I wonder what the provenance is for saying the woman is Anna Petersen. Robert Bain does not include it in his book; I would think he would have if a photo of Anna really existed.

It doesn't look like we ever got an answer for that from here, either: http://rogerjnorton.com/LincolnDiscussio...d-189.html
