Kwasi McKinney v. State of Arkansas

Summary

The court denied McKinney’s fourth petition for permission to pursue coram nobis relief because his ineffective-assistance and trial-error claims were not cognizable in coram nobis proceedings. His allegations of insanity or incompetence also failed because he provided no factual substantiation or showing of an extrinsic, concealed, and previously unknown fact establishing incompetence. The court held that any ineffective-assistance claim had to be raised through the applicable postconviction procedure.
