Multiple law-enforcement agencies were involved in the Friday night arrests of two men in relation to a Kootenai County murder investigation.

Kootenai County Sheriff’s Office spokesman Lt. Stu Miller announced late Friday that one man was in custody who will be charged with homicide in the murder of Coeur d’Alene resident William “Bo” Kirk.

Another man is in custody on charges related to the case, Miller reported.

Kirk went missing last Saturday evening, Oct. 22, after working his shift at Northwest Specialty Hospital in Post Falls.

His body was found Tuesday near the Hayden Creek Shooting Range, northeast of Hayden Lake, in the Coeur d’Alene National Forest.

The cause of death of the 41-year-old X-ray technician was not released, but since Wednesday, detectives with the Kootenai County Sheriff’s Office, Post Falls Police Department and the North Idaho Violent Crimes Task Force have been investigating Kirk’s death as a homicide.

“The body was found dumped off at the side of a road,” Post Falls police chief Scot Haug said earlier this week. “He still had his work badge on.”

“We’re certain that this death was caused by a different person and we’re investigating this as a homicide, but we can’t get into the details of why,” Kootenai County Sheriff Ben Wolfinger said at a Wednesday press conference on the case.

Haug said Wednesday detectives haven’t found any possible reason why someone would want to kill Kirk.

“That’s the million-dollar question,” Haug said. “Everything we’re hearing is that he lived a normal life, had a good relationship with his family, worked at Northwest Specialty with no problems, had no enemies, criminal history or credit problems.”

Law enforcement officials declined to comment on any evidence that was found near the body and his truck that was found engulfed in flames in the 23000 block of North Rimrock Road in the north part of the county at 9:43 p.m. on Saturday. They also declined to comment on any email or telephone conversations Kirk had during the 24 hours before he disappeared.

Kirk is survived by his wife Amanda and their three children. 

Further information on the identity of the suspects and details of how they were apprehended was unavailable as The Press went to press. Those details will be released in upcoming days, Miller reported.

He thanked members of the public for providing numerous tips on the murder case.
