Police secure the area where a shooting suspect abandoned a stolen police cruiser in Post Falls, Idaho on Tuesday, May 5, 2015. Coeur d'Alene Police Sgt. Greg Moore was shot once around 1:30 a.m. after checking on a suspicious individual in the 2800 block of West Wilbur in Coeur d'Alene, Idaho.
From the information I've received so far, it doesn't look like an ambush-style attack. This was just a bad guy doing bad guy stuff and our officers doing what they were trained to do — and that's trying to keep our communities safe. —Police Chief Lee White

SPOKANE, Wash. — A northern Idaho police officer was in critical condition Tuesday after being shot by a suspect who stole his patrol car, led a 125-mph chase and got dragged from under a semitrailer by a police dog and arrested, authorities said.

Coeur d'Alene Police Sgt. Greg Moore was shot once around 1:30 a.m. after checking on a suspicious individual in a neighborhood, Police Chief Lee White said.

"He's still fighting for his life," said Sgt. Christie Wood, spokeswoman for the department. "He's very critical."

Wood declined to say where Moore was shot.

Moore, a 16-year veteran of the department, called dispatch to get information on 26-year-old Jonathan Renfro, White said. Not long after, a resident called police.

The resident "had heard a noise that sounded like a gunshot and they shortly after said that there was a body lying in the street," White said at an early morning news conference.

"From the information I've received so far, it doesn't look like an ambush-style attack," the chief said. "This was just a bad guy doing bad guy stuff and our officers doing what they were trained to do — and that's trying to keep our communities safe."

Renfro has a long criminal record and is currently on probation. He is being held in the Kootenai County Jail.

After Moore was shot, an officer from nearby Post Falls, Idaho, who was listening to radio traffic about the incident, saw a Coeur d'Alene police car race by at about 90 mph, so he gave chase close to the Washington state line, with speeds reaching 125 mph, Post Falls Police Chief Scott Haug said.

The officer found the patrol car abandoned, and the Washington State Patrol and Kootenai County Sheriff's Office helped set up a perimeter, Haug said.

A police dog found Renfro about two hours later hiding under a tractor-trailer, wedged off the ground between the axle area and the truck, near a Walmart in Post Falls, Haug said.

"He was engaged by the dog when he would not comply and taken into custody," Haug said.

White said a motive for the shooting hasn't been determined.

The Idaho State Police is the lead agency investigating the shooting, said Stu Miller, a spokesman for the Kootenai County Sheriff's Office.

Investigators are collecting evidence from multiple scenes, including dash cam video from Moore's car, Miller said.

Miller did not know if the weapon used against Moore had been recovered.

Miller said the last report from the officer was a radio message that he was checking out a suspicious individual in a Coeur d'Alene neighborhood.

"There was no further contact from him," Miller said.

Moore is married, officials said. His age was not immediately available.

Other Coeur d'Alene police officers were maintaining a vigil at Kootenai Health, where Moore was taken.
