Pattern of Abuse

In OCCA case No. F-2013-1129, Aaron Mitchell Stigleman appealed his conviction for First Degree Murder. In an unpublished decision, the court decided to reverse and remand the case for a new trial. One judge dissented. The case involves Aaron Stigleman, who shot and killed his mother in Elk City, Oklahoma, on February 13, 2013. At the time of the incident, he lived with his girlfriend and mother, both of whom had a history of drug use, specifically methamphetamine. Aaron was believed to be suffering from paranoia and hallucinations due to his drug use leading up to the shooting. Witnesses, including his girlfriend, testified that he accused them of trying to kill him before he shot his mother in the head. During his trial, Stigleman's attorneys failed to secure an expert witness to help argue that he was under the influence of methamphetamine and not in control of his actions at the time of the crime. They tried to get funding for an expert, but their requests were either late or not sufficiently justified. As a result, they could not present an argument related to his mental state or introduce expert testimony that could aid in the defense of insanity or diminished capacity. The court noted that Stigleman's behavior before, during, and after the incident indicated the possibility of a serious mental health issue caused by drug use, which warranted an expert’s evaluation. The silence of an expert on the mental health issues surrounding his drug use could have made a significant difference in the outcome. The court ruled that Stigleman’s attorneys did not adequately represent him by failing to present a complete defense. The decision emphasized that the right to present a complete defense is constitutionally guaranteed. Based on these findings, the court deemed it necessary to grant Stigleman a new trial to allow for proper evaluation of his mental state. While one judge expressed disagreement, arguing that the defense had not shown that the lack of expert testimony prejudiced Stigleman's case, the majority concluded that the claims and evidence presented merited a reversal and a new opportunity for a fair trial.
