PHOTOS - St. Louis firefighters are battling a huge, five-alarm fire in a warehouse that sent a plume of thick black smoke up from the Botanical Heights neighborhood. A fire truck was smashed when a wall of the building collapsed about 11:30 a.m. Wednesday. The fire started small in the basement of the warehouse near 39th Street and Park Avenue about 10:15. a.m. But it proved difficult for firefighters to find and contain in the smokey interior of the business, Park Warehouse Service at 3937 Park. Eventually firefighters were ordered out of the building by radio call and loud horn blast. About 11:30 a.m., part of the south part of the building collapsed. There was a whooshing sound and black smoke billowed out of the building's doors and windows. Fire burst through the roof and a wall on the south side of the building collapsed onto a fire truck.
