This to reply about Graham Barnett and his killing of Will Babb in Langtry. It is spelled Rabb incorrectly in your story.
I have the book "From Darkness Into Light' written by Will Babb's daughter that tells about the killing. WILL WAS MY GRANDMOTHERS OLDEST BROTHER.
I have written a book titled Echoes Along the Pecos River that tells the story about this event.
Do you have any facts on this subject? or want to correspond with me?
