Missouri Court of Appeals, Southern District / Aug 29, 2025
STATE OF MISSOURI, Plaintiff-Respondent v. ANDREW J. COOPER, Defendant-Appellant
Andrew J. Cooper appealed his conviction for armed criminal action, arguing that the trial court erred by submitting a jury instruction on armed criminal action with involuntary manslaughter as the underlying felony. The appellate court affirmed the conviction, finding that Cooper failed to preserve the instructional error for review by not making a specific objection at trial or in his motion for new trial. The court declined to exercise plain error review, and further noted that even if reviewed, the argument would fail on the merits due to controlling Supreme Court of Missouri precedent.
