KELLOGG, Idaho — Idaho State Police said Monday they are continuing to investigate a shooting that left four people dead in the small city of Kellogg in northern Idaho.

“Detectives arrived late last night ... They are continuing to work and process the scene,” a state police spokesperson said in a text message.

Crime scene tape on Monday blocked off parts of an apartment complex in Kellogg, about 36 miles east of Coeur d’Alene, KXLY-TV reported. The shooting occurred at multi-dwelling units behind the Mountain View Congregational Church on Sunday, The Shoshone News-Press reported on the newspaper's Facebook page.

Law enforcement has not yet identified the victims or the suspect.

Around 7:20 p.m. on Sunday, the Shoshone County dispatch center received a 911 call indicating that multiple people had been killed inside a residence in Kellogg, state police said Sunday night in a news release. Law enforcement officers found four people dead when they arrived and detained a 31-year-old male believed to be connected with the deaths, according to the release.

The Shoshone County Sheriff's Office, which said in a Facebook post that it responded to the scene with the Kellogg Police Department, said the four people died of gunshot wounds.

The Kellogg Police Department did not immediately respond to an email from The Associated Press seeking additional information.

Law enforcement believes everyone connected with the incident is accounted for and that there is no additional threat to the community, state police said.
