Updated 3:45 p.m. City fire chief Dennis Jenkerson says the cause of the fire is not suspicious, and building appears to be up to code:
"The question that came up was the draft stops up in the attic, and in reviewing the plans, and also we sent firefighters over there this morning and we went up in the attics of the remaining buildings, and all buildings had the draft stops as required. This was just a very hot and quick-moving fire."
