Rollie says: A BYU professor of Church History, Gustive O. Larsen, seems to back up Lee's story, when he wrote in 1958:: "To whatever extent the preaching on blood atonement may have influenced action, it would have been in relation to Mormon disciplinary action among its own members. In point would be a verbally reported case of a Mr. Johnson in Cedar City who was found guilty of adultery with his stepdaughter by a bishop's court and sentenced to death for atonement of his sin. According to the report of reputable eyewitnesses, judgment was executed with consent of the offender who went to his unconsecrated grave in full confidence of salvation through the shedding of his blood. Such a case, however primitive, is understandable within the meaning of the doctrine and the emotional extremes of the [Mormon] Reformation."

There are problems with what you have posted.
First, you have posted material and cited it as original when, in fact, you were cutting and pasting from a secondary source without attribution. While that may be sufficient for the rubes who inhabit this board it isn't for me or anybody else who reads with a discriminating eye.
Second, the quote has nothing to do with John D. Lee's quote which begins your post. Lee did not refer to this event in his memoirs.
Third, you have misquoted the UHQ material. The word "the" is missing from before the word "reputable" which changes the tone of Larson's supposed endorsement which you so valued. Slightly.
Fourth, Larson does not provide any reference to this quote. Read in context in the article, he is just quoting rumor.
Fifth, your post relies heavily upon material from Lee's confessions. This material comes from a portion of Lee's confession which one of Lee's biographers characterizes thusly: "I have excluded . . . a section of Confession which is not about Lee's life, and which seems to be of questionable authenticity."

I can cut and paste the entire article in an email to you but I will not post copyrighted material on a board. The copyright might have expired by now, but I'm not taking chances.
