Stout joined the Mormons in Missouri in 1838 and followed them to Nauvoo, where he rose quickly to become a top leader in the Nauvoo Legion and chief of police, a position he also held at Winter Quarters. He became the first attorney general for the Territory of Utah, was elected to the Utah Territorial Legislature, and served as regent for the University of Deseret (which later became the University of Utah) and as judge advocate of the Nauvoo Legion in Utah. In 1862, Stout was appointed US attorney for the Territory of Utah by President Abraham Lincoln. In 1867, he became city attorney of Salt Lake City, and he was elected to the Utah House of Representatives in 1881.
But Stout’s history also had its troubled moments. Known as a violent man and aggressive enforcer, he was often at the center of controversy during his days on the police force and was accused of having a connection with deaths in Nauvoo and Utah. Ultimately, however, none of these allegations ever found traction, and the leaders of the LDS community, especially Brigham Young, saw to it that Stout was promoted to roles of increasing responsibility throughout his life. When he died in 1889, Hosea Stout left a complicated legacy of service to his state, his church, and the members of his faith community.More information is available here.
