Died in jail or a lockup
Hyrum Smith
Hyrum Smith, brother of Joseph Smith, was held with him in the Carthage jail in Hancock County, Illinois. On June 27, 1844, a mob stormed the jail and killed both brothers, according to an 1887 account. That account says the jail staff did not resist the mob, while a later 1918 account says the mob shot the brothers after breaking in. The sources differ on how the jailers responded beyond that.
Cause of death, as reported: Taken from custody and lynched. A mob stormed the Carthage jail in Illinois, where Hyrum Smith was held with his brother Joseph, and shot both men to death.
