COEUR D'ALENE, Idaho (AP) — An Idaho jury will determine if a man convicted of killing a Coeur d'Alene police officer should receive a sentence of life in prison without the possibility of parole or the death penalty.

The jury found 29-year-old Jonathan Renfro guilty of first-degree murder on Friday for the May 2015 killing of police Sgt. Greg Moore. He was also found guilty of robbery, removing a firearm from a police officer and concealment of evidence.

The jury then on Tuesday agreed with prosecutors on three of the four aggravating factors that showed Renfro has the inclination to commit murder, which would make him a continuing threat to society, The Spokesman-Review reported . The last phase of the trial begins next week.

"(Renfro) killed without provocation for simply the motivation of not wanting to go back to prison," Deputy Kootenai County Prosecutor David Robins said to the court. "Greg is dead because he is a police officer trying to defend the community."

Moore was killed while on a routine patrol where he encountered Renfro. Prosecutors previously said the convicted felon was high on methamphetamine and ambushed Moore. He then took Moore's firearm and fled.

"I'm not going to suggest what Mr. Renfro did was proper or brave," defense attorney Keith Roark said. "The state is asking you to take that one murder he is convicted of, and that was a horrible act, and extrapolate that he will commit murder again."
