Missouri Court of Appeals, Eastern District / Feb 10, 2026
Daniel T. Williams, Appellant, v. State of Missouri, Respondent.
Daniel Williams appealed the denial of his Rule 29.15 motion for post-conviction relief, arguing that his trial counsel was ineffective for failing to investigate his mental state. Williams contended that such an investigation could have revealed mental health issues relevant to a diminished capacity defense. The appellate court affirmed the motion court's judgment, finding that Williams failed to demonstrate how additional information about his mental state would have aided his defense or satisfied the prejudice prong of the Strickland test.
