Ervil LeBaron
Ervil Morrell LeBaron (February 22, 1925 – August 16, 1981) was the leader of a polygamous Mormon fundamentalist group who ordered the killings of many of his opponents, using the religious doctrine of blood atonement to justify the murders. He was sentenced to life in prison for orchestrating the murder of an opponent, and died there.
He had at least 13 wives in a plural marriage, several of whom he married while they were still underage, and several of whom were involved in the murders.
History
After The Church of Jesus Christ of Latter-day Saints (LDS Church) officially abandoned the practice of polygamy in 1890, some polygamous Mormons, who would later be excommunicated from the main LDS Church, moved south to Mexico to continue the practice without the interference of U.S. law enforcement. Alma Dayer LeBaron, Sr. was one of these people, and in 1924 moved his family, which included his two wives and eight children, to northern Mexico. There, the family started a farm called "Colonia LeBaron" in Galeana, Chihuahua.
