Popular belief, with the help of Juanita Brooks 1950 book on the Massacre holds that the event was orchestrated by Brigham Young and local members and sought to cover it up, if not blamed some church members for be fiery in rhetoric when the people later attacked had mocked church members by claiming they had the gun that killed the prophet Joseph Smith Jr. However, what has been overlooked was Young's warnings to leave the travelers alone and when those wanting to attack heeded not, Young excommunicated them before they attacked the train. After finding out the attack went on, Young had the men tried in court. In the end, all works on the Massacre made the church MORE open about this part of its history, something never truly hidden by church authorities. A monument was made and dedicated by the church president, Gordon B. Hinckley, in 1999. The church later helped make the site a National Historic Landmark in 2011.
