There is alot more to the story than we will ever know. They are neighbors, and the woman's husband is a hunter education instructor. He has hunted with the trooper before.
I can't understand why she would have been in the woods without an orange hat and jacket on. Not saying she was in the wrong, but knowing that it's deer season, and that it is a regulation for hunters to wear it for their own safety, wouldn't you?
Also there is speculation that she was hit by a ricochet not actually shot...
