Fire crews rushed to Chattanooga Valley Road around six Friday morning, only to see flames shoot through an attic.
You can see from the video we shot from a hill, the blaze devoured the inside of the home, nearly gutting it.
Captain Shaugn Curran, with the Walker County Fire Department, says, "First units on the scene found very heavy fire coming through the roof."
Family members were too upset to go on camera, but they tell us their elderly relative was having health problems.
So, he was living with another family member when this happened.
Curran adds, "So, nobody was here at the time of the fire."
The fire took most of the morning to get under control.
Curran says, "We had real good response from our crews and they did the best they could. There was a lot of fire to put out."
Investigators do not know how the fire started, and they cannot put a dollar amount on the damage.
The home now resembles charred toothpicks, and it is hard to see past them.
Curran says, "Our investigator has been looking at it, so it's up to them to decide."
Three days after Christmas; these aren't the set of flashing red lights anyone wanted to see.
It could take days for fire officials to determine what started the fire.
No word on if the homeowner had insurance.
