The Arizona Supreme Court has turned down an appeal for a man convicted and sentenced to death for murdering a Phoenix police officer.

The justices ruled unanimously Friday in the case of Donald David Delahanty in the May 2005 killing of Officer David Uribe. The officer was shot after he pulled over a car in which Delahanty was a passenger.

According to testimony, Delahanty had said several times before the day of the shooting that he would kill any police officer who pulled him over.

Delahanty was sentenced to death for the murder of Uribe. He also was convicted of various other charges that he tried to burn the car in which he was riding and that he tried to arrange killings of a witness and the witness' mother.
