Two Idaho prison inmates and a neurologist testified for the defense Friday in the mitigation phase of Jonathan D. Renfro’s murder trial.

Defense attorneys are expected to wrap up testimony on Monday, when prosecutors will take over in an effort to persuade jurors to sentence Renfro to death.

The 29-year-old defendant who was convicted two weeks ago of killing Coeur d’Alene Police Sgt. Greg Moore in May 2015 by shooting him in the face with a concealed 9mm pistol, could serve life in prison or be sentenced to death, depending on the jury’s verdict.

Attorneys are expected to hand the case over by the middle of next week to the 15-member jury panel, which has been seated since the trial began in early September.

Defense attorneys used testimony by inmate Scott J. Carr of Weippe to show their client wouldn’t be dangerous to other inmates if he is sentenced to life behind bars.

Carr, who appeared shackled and wearing prison pajamas, has spent 8 years in prison and will be released next month from the Boise penitentiary where he is serving time for grand theft, he said. He has served time for burglary and other theft charges as well as for being a felon in possession of a handgun.

Carr said he met Renfro in prison in 2008 and served with him until 2011. The two had similar backgrounds: They both liked to hunt and fish and spend time outdoors, Carr said. A rural background was unusual for inmates, he said.

“He was a country boy like me,” Carr said.

He didn’t remember anyone coming to visit J.D. Renfro in prison, putting money into his commissary account, or sending him mail.

“He never had money... I never seen him ever get a visit,” Carr said. “I don’t think he had any family support; maybe a letter.”

He wasn’t an instigator, he wasn’t violent, but he stood up for himself, one of the rules inmates must follow if they expect not to be targeted.

“He always just goofed around,” said the 30-year-old Carr. “We were both kids in prison.”

Defense attorney Keith Roark asked if his client was ever involved in fights.

“Everybody does in prison,” Carr said.

People serving life without parole aren’t necessarily violent, and are often employed in the prison’s fabrication business, he said.

On cross examination, deputy prosecutor David Robins asked if Carr knew about a murder last month in the prison yard of the Boise pen.

Carr said he was in the yard when it happened.

“Everyone is different,” he said. “They are just doing their prison time.”

Convict Chad Tipton, an Aryan gang member who spent time with Renfro in the Kootenai County Jail and is serving penitentiary time for grand theft, assault and firearms possession — he has spent 15 years behind bars, he said — characterized Renfro as respectful.

Tipton accused correction deputies of messing with Renfro, harassing him in an effort to get him to act out.

“The way he has composed himself is a testament to his will,” Tipton said.

Roark asked Tipton if Renfro was violent.

“I consider myself a violent person,” Tipton said. “I don’t consider him to be dangerous at all.”

The trial will resume Monday at 9 a.m. in Coeur d’Alene’s First District Court.
