State of Minnesota vs. Hinckley
Annotate this Case
Tyson Joe Hinckley was convicted of first-degree arson, second-degree burglary, and theft of a motor vehicle. Hinckley had stolen a vehicle from a garage and started a fire that damaged the garage and an adjacent home. He sought to assert a mental-illness defense at trial, submitting multiple psychological reports attesting to his mental illness at the time of his offenses. However, the district court rejected the mental-illness defense, concluding that Hinckley had not provided sufficient evidence that he was acting under a defect in reasoning caused by mental illness at the time of the offenses. Hinckley was found guilty at trial, and the court of appeals affirmed the convictions.
The Minnesota Supreme Court reversed the lower courts' decisions, holding that the district court had abused its discretion by denying Hinckley the right to assert a mental-illness defense. The Supreme Court found that the psychological reports submitted by Hinckley provided sufficient evidence to establish a prima facie case of a mental-illness defense. The court concluded that the district court's error was not harmless beyond a reasonable doubt, as it could not be certain that the jury's verdict was surely unattributable to the error. The case was remanded for further proceedings consistent with the Supreme Court's opinion.
