“When I pulled up, there was probably 30 foot flames above the building, so it was called a defensive fire right away,” Battalion Chief Dave Ennes said. “We’re not going to commit our people to a building like this that’s already had fires in it.”

No one was inside the building, firefighters said.

The fire was eventually knocked down, but firefighters remained on scene Friday morning to put out hot spots.
