In May 2023 Richard Turley and Barbara Jones Brown published a book through Oxford University Press entitled Vengeance is Mine, which documents the aftermath of the Mountain Meadows Massacre, including the efforts of Church and civic leaders in southern Utah to conceal their involvement in the atrocity through witness silencing and misinformation, as well as evading or stalling investigations by both government agencies and church organizations by lack of cooperation and political maneuvering. They also chronicle details about the nine individuals who were ultimately indicted, the five who were apprehended, and John D. Lee, who ultimately faced execution. In this episode of Church History Matters, we sit down with both Richard Turley and Barbara Jones Brown to discuss their important book, to hear their informed insights and perspectives, and to consider what Latter-day Saints and others can learn from this tragedy and how we can productively move forward.
