Missouri Court of Appeals, Eastern District / Apr 29, 2025
State of Missouri, Respondent, vs. Mark J. Matlock, Appellant.
Mark J. Matlock appealed his jury convictions for voluntary manslaughter, armed criminal action, and unlawful use of a weapon, arguing the trial court erred in admitting double-hearsay testimony and excluding evidence of the victim's violent nature. The appellate court affirmed the judgment. It found the admission of hearsay, while erroneous, was not outcome-determinative due to cumulative evidence, and the exclusion of other testimony was not preserved for review due to a lack of an offer of proof.
