Authorities said that after police were called to the Branscum home before 2 a.m., officers saw Amanda Branscum lying in the road uninjured; the father and children were found dead inside the house.
Re-reading this story, some elements to it are bizarre.
I think maybe they are referring to a drive thru window like you would see at a fast food place. It seems if he had driven through a plate glass window they would have said more about that. As far as the mother being in the road it says, she was overcome by hysteria so I would guess she found the bodies and got as far as the street and collapsed. That's just a guess
