Officials say a large fire that burned Saturday night is now being called a four-alarm fire.
It took approximately 150 firefighters an hour and a half to get the flames under control, according to a fire department spokesman.
Those living in a nearby condominium complex south and west of the scene were evacuated due to unsafe carbon monoxide levels. Approximately 20 people were forced to find other places to sleep overnight, but were allowed to return home Sunday around 9 a.m.
Multiple ABC15 viewers have submitted photos and video Saturday night of massive flames and thick smoke.
