Justin W. Stidham, 32, was shot and killed in Columbia, Missouri, on November 8, 2021. Authorities identified a single suspect, Mark Achterberg, who fled after the shooting and was later apprehended in Iowa and returned to Boone County to face charges.

Achterberg was originally charged with first-degree murder and three additional felonies. Prosecutors later amended the charges; he pleaded guilty to second-degree murder and one count of unlawful possession of a firearm and admitted in court to shooting and killing Stidham. At a pre-trial conference, reason for the shooting was not disclosed. Stidham’s father and sister delivered victim impact statements describing the loss to the family.

Achterberg was sentenced to 20 years in prison. If anyone knew Justin or has information about the events leading up to November 8, 2021, please share what you know.
