PHOENIX -- The U.S. Supreme Court has been asked to review the case of an Arizona death-row inmate scheduled to be executed this week.
Lawyers for Robert Glen Jones Jr. filed the petition with the nation's high court Monday after a federal appeals court declined a rehearing.
The 44-year-old Jones was sentenced to death for the fatal shootings of six people during two armed robberies in Tucson weeks apart in 1996.
He's scheduled to be executed by injection Wednesday at the state prison in Florence.
Jones' attorneys had asked the 9th U.S. Circuit Court of Appeals for an evidentiary hearing, arguing that a now-deceased Pima County prosecutor withheld evidence at Jones' 1998 trial.
The 9th Circuit also denied a motion by Jones' lawyers to remand his case back to a district court.
