John Buttars swears affidavit saying he heard Martin Harris say he "knew" the BOM to be true.
John Buttars, Affidavit, July 2, 1933, in Deseret News, July 15, 1933, [37]
The third affidavit reads:
"John Buttars, being duly sworn deposes and says that I am now of the age of 77 years. I have been a resident for 63 years of Clarkston. Thomas Godfrey, William Sparks and myself went to visit Martin Harris in the winter or spring of 1875, as I remember. At that time Thomas Godfrey asked Martin Harris if he believed the Book of Mormon to be true, and he said, 'No, I don’t believe it to be true, I know it is true.” Then he stated the conversation as Thomas Godfrey has given it in his affidavit which has just been read to me, and the statement as Thomas Godfrey has given it, is true to the best of my knowledge."—Signed by John Buttars.
