The evidence that sealed Mrs. Surratt's fate

[RJNorton]

Seems I am increasingly saying the same thing...i.e. I read something but cannot recall where. This time it has to do with Weichmann and his deathbed statement. I believe I read somewhere that Weichmann's deathbed statement may have been "contrived" and may not be valid. Does anyone know the specifics on this? Are there valid reasons that cast doubt on his deathbed statement?
