The building, already heavily damaged from a January fire, was nearly destroyed by 8:30 p.m.Charred remains of the outer walls fell to the ground in clumps and only a skeleton of the building remained. "It was going pretty good when we got here," King said. In this video, we show you the fire and read highlights of the story.
