PROVO, UT - APRIL 25, 1985: (FILE PHOTO) Ron Lafferty (C) is escorted out of the Utah County Court House by Utah County Sheriff Deputies after the first day of jury selection in his murder trial April 25, 1985 in Provo, Utah. Lafferty and his brother Dan were convicted for the July 1984 murder of Lafferty's sister-in-law and her 15-month-old daughter, which he said was an order from God. The brothers were members of a fundamentalist Mormon splinter group who embraced polygamy, the superiority of the white race, the end of the world and the right to commit murder in the name of God. Dan Lafferty and his brothers were excommunicated by the mainstream Mormon Church. Lafferty and the fundamentalist Mormons are chronicled in Jon Krakauer's new book "Under the Banner of Heaven: A Story of Violent Faith." (Photo by George Frey/Getty Images)
