Authorities are trying to figure out what caused a fire at a Preston County home late Wednesday night.

It's a story you saw First on Five.

The blaze broke out just before midnight at a home off of Ridge Road.

When crews got on scene, the home was fully engulfed.

The family was home at the time, but everyone was able to make it out safely.

There's no word on what may have started the fire, but the state fire marshall has been called in to investigate.
