A scheduling delay has postponed an investigation into last month’s downtown Coeur d’Alene fire.

Coeur d’Alene fire investigator Craig Etherton said Friday that the half dozen investigators working to determine the cause of last month’s fire at Fourth Street and Lakeside Avenue have not been able to schedule a time when all of them could be at the scene.

The earliest availability is Feb. 20, two weeks away.

“Everyone has a different schedule,” Etherton said. “The more people involved in it, the more complicated it gets.”

He said all the investigators, most of them hired by insurance companies of tenants and the building’s owner, must be on scene at the same time.

Once the investigation starts again, it should wrap up within two days, he said.

The three-alarm fire that started around 1:30 a.m. Jan. 20 on the corner of Fourth and Lakeside destroyed the Cole Taylor Salon, Schmidty’s Burgers, Heart City Tattoo, 720 Haberdashery, and Farmer’s Insurance. The Emerge gallery, located on the far north side of the commercial building, was also affected. A firewall separated the nonprofit gallery from the adjoining businesses, Etherton said.

The fire appears to have started near the roof above the Cole Taylor Salon before burning the surrounding businesses, Fire Chief Kenny Gabriel said.

Footage from a camera on a nearby rooftop recorded the start of the fire and firefighting efforts.

Etherton said it should take no more than two days to wrap up the investigation.

“The on-scene investigation should be concluded by then,” he said. “We’ll prepare the reports after that.”
