Firefighters put out a fire that consumed a vacant home in the Dutch Hollow neighborhood early Wednesday morning.
A motorist on Illinois 161 called in the fire shortly before 3 a.m.
The Belleville Fire Department, which responded with two ladder units and a pumper, extinguished the main part of the fire in 20 minutes, Chief Tom Pour said.
Crews were more cautious with remaining hot spots, as power lines connected to the burning house could have fallen into and electrified puddles on the ground, Pour said.
In all, the fire took an hour and a half to extinguish.
Because the home was vacant, there were no deaths or injuries; however, an investigative dog was able to find evidence of an accelerant.
“You expect to find flammable liquids in garages ... but anytime it’s in a residence, it’s suspicious,” Pour said.
There was no damage to surrounding property, Pour said.
