An Oklahoma death row inmate is asking a state appeals court to overturn his first-degree murder convictions and death sentence.
Oral arguments are scheduled Tuesday before the Court of Criminal Appeals in the case of Victor Miller.
The 49-year-old Miller is one of two men convicted of killing 77-year-old retired Tulsa banker Mary Agnes Bowles and 44-year-old Owasso trucking company owner Jerald Thurman on August 31, 1999.
Investigators believe Bowles was abducted from the Tulsa Promenade mall parking lot and taken to a secluded area, where her killers confronted Thurman as they robbed Bowles of her car.
The state appeals court last year upheld the conviction and death sentence of Miller's co-defendant, 48-year-old John Fitzgerald Hanson.
Death sentences for Miller and Hanson have been previously overturned on appeal.
