Columbus fire officials say they are unable to determine the cause of last month's three-alarm blaze at a west side warehouse. Meanwhile, neighbors of the fire-gutted Dick Cold Storage warehouse on Valleyview Drive say they are getting sick from the stench left behind. At issue is the smell of rotting meat in tractor-trailers damaged by the August 19 blaze. Residents say they can't go outside without throwing up and rats are starting to populate the neighborhood. Columbus city officials say they're working with the property owners to clean up the mess.
