Twin Falls fire crews worked to extinguish a fire that severely damaged a mini-golf course building late Sunday night. According to the Twin Falls Fire Department, crews were called out at around 11:30 p.m. after a passerby reported seeing heavy smoke and odor in the area. When the three engine crews arrived the upper part of the two-story building at Putters Mini-golf Course was on fire. It took firefighters about thirty minutes to get the blaze out. The fire was mainly contained in the attic area. A ladder truck with Rock Creek Fire assisted with the call. Twin Falls Fire said there were no injuries reported. The cause is under investigation. Monday morning a large portion of the roof could be seen caved in.
