UPDATED 4:46 p.m. Dec. 15, 2010:
KSDK is reporting that the fire was in an unoccupied, one-story, brick warehouse near Gratiot and Theresa.
They also report that a cutting torch, perhaps being used for workers to ready the space for a new occupant, is to blame for the blaze.
A large fire has been reported near the Steelcoate building near Chouteau Ave. and Grand Blvd. We'll keep you updated as we confirm more about this story.
