While in prison, William A. Hickman publishes the book 'Brigham's Destroying Angel,' the first Mormon expose by a confessed murderer. He is again excommunicated, this time by church court, on 12 Jan. 1878. On 21 Mar. 1934, the First Presidency approves Hickman's rebaptism and "his former blessings restored," which occur by proxy on 5 May 1934.
