Gilberto Martinez-Marmol v. State of Arkansas

Summary

The court denied Martinez-Marmol's petition to reinvest jurisdiction in the trial court for a coram nobis proceeding. It held that his competency, prosecutorial-misconduct, confession, and judicial-error allegations concerned matters available at trial or on direct appeal, while his ineffective-assistance claims were not cognizable in coram nobis proceedings. His Brady allegation also failed because it was conclusory and did not identify specific material and prejudicial evidence that had been withheld.
