Murder trial

In 1844, Davis was indicted and tried for the murders of Joseph Smith and Hyrum Smith. The Smiths had been imprisoned in Carthage Jail when the prison was stormed by an armed mob that shot and killed them. As a captain in command of the Warsaw Rifle Company of the Illinois militia, Davis was accused of having ordered his men to storm the prison. At trial, Davis and four other defendants were found by a jury to be not guilty of the murders.
