Investigators are still trying to determine what started a fire at a commercial building in Hamilton on New Year’s Day. Hamilton Volunteer Fire Department Chief Brad Mohn says firefighters were called at around 4:50 p.m.

"There was a structure fire on North First Street here in Hamilton at the Sew and Vac shop. There were no injuries and the building was unoccupied at the time," said Mohn.

When firefighters arrived the fire was quickly spreading throughout the interior of the building.

"The damage was quite extensive; it gutted the interior of the Sew and Vac shop," Mohn said. "Global Wireless, which is attached to it sustained some smoke damage, but that is it for that side of the building. The structure is still sound; it just gutted the contents."

The building is located along Highway 93 near Fairgrounds Road. Traffic on the highway had to be delayed for about 30 minutes while firefighters tackled the blaze.
