Fire officials did not see evidence suggesting an explosion had occurred, Rupard said.
"That was what was reported. We can't determine if there was one. We didn't find any evidence," the fire chief said.
Firefighters had the fire under control at 6:26 p.m.
The fire, according to Rupard, was concentrated in the basement area. It affected at least one bedroom and a bathroom.
The fire also caused smoke to consume much of the dwelling.
"There was a lot of smoke," Rupard said. "It was heavily charged throughout the house."
During the department's preliminary investigation, Rupard said his firefighters discovered things that "did not look normal," he said.
Once the fire chief began his walk-through inspection, he noticed the oddities as well.
"Once I saw the stuff that did not look normal, that's when I called KSP and asked the sheriff's office to begin the investigation," he said. "The type of evidence we found, well, from experience, from what I saw, that's what I call throwing the flag up and I called in the experts. That's why I called the state police."
Rupard said around 15 canisters of evidence were taken from the home and shipped to the state lab in Frankfort.
Investigators were on the scene until 5:30 a.m. Wednesday morning.
A total of nine fire trucks and 27 firefighters responded to the blaze.
A call to KSP Trooper Kevin Dunn, who is leading the investigation, was not returned by press time.
