Aerial footage showed the home reduced to a charred hole in the ground with debris scattered for hundreds of feet all around.

According to the sheriff’s office, testing revealed a leak in the gas line to the home that allowed gas to leak into the ground, to the basement foundation and into the basement level, where it built up and then was ignited.
