Mackey v. State

Summary

The court denied permission to reinvest the trial court with jurisdiction to consider a coram-nobis petition challenging the petitioner's murder conviction. The petitioner's allegations that he suffered from post-traumatic-stress syndrome, hallucinations, and flashbacks did not establish incompetence, identify an extrinsic fact unknown at trial, or satisfy the factual-support and diligence requirements for coram-nobis relief. The court also held that any ineffective-assistance claim was not cognizable in a coram-nobis proceeding.
