Fire crews in Posey County were dispatched to a house Saturday evening after reports of an explosion.
When crews arrived on scene they found a fully-involved structure fire. At this time they are not sure whether there was an actual explosion.
Four people were inside the home at the time.
Shelly Dossett is at a local hospital in fair condition. Two others were treated at the scene. None of the injuries were life-threatening. Fire officials say some of the family's pets were likely killed in the explosion.
