The Lafferty murders occurred in 1984, when older brothers Dan and Ron Lafferty killed their pregnant sister-in-law Brenda Lafferty. When caught, Dan and Ron claimed to have been ordered by God to kill Brenda because they believed she was the cause of Ron's divorce from his wife. The murder became the subject of a book in 2003, titled Under the Banner of Heaven, which explores the murders and their connection with the Mormon church, and a subsequent movie.

Book and Movie
Under the Banner of Heaven: A Story of Violent Faith is an investigative nonfiction book by best-selling author Jon Krakauer, first published in July 2003. It is a juxtaposition of two stories: the origin and evolution of The Church of Jesus Christ of Latter-day Saints (Mormons), and a modern double murder committed in the name of God by brothers Ron and Dan Lafferty, who subscribed to a fundamentalist version of Mormonism. The book examines the ideologies of both The Church of Jesus Christ of Latter-day Saints and the fundamentalist Mormons polygamous groups, such as the Fundamentalist Church of Jesus Christ of Latter Day Saints ("FLDS"). The book opens with news accounts of the 1984 murder of Brenda Lafferty and her infant daughter Erica, and then goes into the history of Mormonism, starting with the early life of Mormon founder and prophet Joseph Smith, following his life from a criminal fraud trial to leading the first followers to Jackson County, Missouri and Nauvoo, Illinois. In July 2011 Warner Bros. purchased the film rights to the book with Ron Howard directing and Dustin Lance Black writing the screenplay.
