PHOENIX -- A March 6 execution date has been set for an Arizona prison inmate who's been on death row since 1985.
The Arizona Supreme Court granted a motion for an execution warrant Tuesday for 70-year-old Edward Harold Schad.
Schad's attorneys asked the state's high court to deny the execution warrant request or at least delay ruling on it.
They say Schad still has a motion for a rehearing of his case before the U.S. Supreme Court and there are questions about the constitutionality of Arizona's lethal injection procedure.
Schad was convicted in the killing of 74-year-old Lorimer ``Leroy'' Grove of Bisbee, who went missing on a drive to Washington state. His strangled body was found south of Prescott in August 1978.
Schad was arrested a month later, driving the victim's car.
