What do I say... what an unspeakable tragedy this is! I wonder what made Libby take the video/audio? If they felt the danger from the distance, could they run away, hide? Did they make any attempts to call 911 or family? That “go down the hill” sounds so controlled and deliberate. I wonder if this evil monster had a gun to control the girls... Do you think this was a planned attack or wrong-time wrong-place situation?
