--RAW VIDEO:  Aftermath Of Three-Alarm Fire  

Crews responded to an alarm at 11 p.m. Sunday night, and found heavy smoke and flames coming from the building.  

As crews battled the fire, they were pulled back to a defensive position when the roof and walls started to collapse.  

Fire Chief Bernie Kanger said there was a lot of material inside the building for the fire to go through, and the entire structure is considered a total loss.

Investigators believe the building and contents were valued just under $1 million dollars.
