William “Bo” Kirk was kidnapped, bound and shot to death in a road-rage incident in Coeur d’Alene, prosecutors alleged in court Monday afternoon.

David E. Hutto,44, is accused of killing Kirk last week. A judge set bail at $2 million. He faces up to life in prison if convicted.

A second person suspected of aiding Hutto has been arrested and is in the custody of federal agents.

Hutto was arrested Friday evening at the Coeur d’Alene Burger King on Appleway Avenue and booked into the Kootenai County Jail on suspicion of second-degree murder. His arrest came three days after Kirk’s body was found near Hayden Creek in the Coeur d’Alene National Forest.

The U.S. Attorney’s office said Monday it has no comment on that man’s arrest or any potential charges he faces.

Investigators haven’t revealed how they found Hutto or what evidence they have of his involvement in Kirk’s death. Autopsy results are not being released yet. A judge has sealed Hutto’s case file.

Kootenai County Sheriff Ben Wolfinger credited the “great detective work” of his investigators working the case with the Post Falls and Coeur d’Alene police departments and the North Idaho Violent Crimes Task Force.

“They worked hard. I don’t think anybody got more than about four or five hours of sleep any night since we found Bo Kirk’s body,” Wolfinger said Monday.

Investigators were flooded with over 400 tips from the public after authorities released photos and video showing someone driving Kirk’s pickup truck to two local banks before 9 p.m. Oct. 22 and withdrawing cash from Kirk’s accounts. The driver wore a mask over his nose and mouth, a stocking hat, a bulky flannel sweater and gloves. A second man was partly visible in the truck in surveillance videos released to the public.

Kirk’s truck later was found on fire in the 23000 block of North Rimrock Road, 8 miles from where his body was found near the Hayden Creek shooting range.

Kirk, 41, disappeared Oct. 22 after he left his job as an X-ray technician at Northwest Specialty Hospital in Post Falls. The husband and father of three never made it home that evening.

Investigators also served a search warrant Friday at the home where Hutto has been staying in the 1300 block of East Miles Road in Hayden.

Court documents show that Hutto has multiple convictions for grand larceny, burglary and breach of trust with fraudulent intent in South Carolina/Scott Maben, SR.
