The owners were at work when the blaze started, but a neighbor who noticed smoke called 9-1-1.Four fire departments responded, but upon arrival they saw it was already gutted.”Well, we got a call from a passerby that went by and said there was black smoke rolling out of the building. When we arrived the building was fully involved. There was flames coming out of the top of the building, lots of smoke coming out of the back. At that time it was pretty well gone when we got there.”No word yet on what caused the fire.The state Fire Marshal’s office will investigate.
