    Sixth District Court, Sanpete County; Fifth District Court, Cedar City, Utah. John Coltharp and Samuel Shaffer, leaders of the 'Knights of the Crystal Blade' splinter sect, each 'married' the other's daughter — girls of seven and eight — under the group's revelation claims. Coltharp pleaded guilty in June 2018 to child sodomy and child bigamy and Shaffer to child rape and child abuse; both were sentenced to twenty-six years to life. It was the first prosecution under Utah's child-bigamy statute.
