Did Jennifer kill the Sheriff's daughter?

It's left open to the viewer, I guess.

Even though she wasn't in her right state of mind, I don't think Jennifer would have killed the daughter.

My guess is Jennifer filled the Sheriff's wife in with the details of the assault/rape, and instructed her to tell him that Jennifer was at the park. Since his wife met him out on the porch to tell him, the daughter was probably in the house.

She probably told his daughter everything but I don't think she would have hurt her physically. The daughter couldn't control her father's actions and wasn't responsible in any way.

I don't think so. As I was watching that sequence unfold, I thought to myself, she can't murder or harm the daughter, that would totally change the tone of her character and the film itself, then she would be "no better" than the animals who attacked her.

I really don't buy her telling the wife the whole truth, as the wife could possibly have a "stand by your man" reaction, and deny it, or if she was an abused spouse, something the film does not really point towards, then she may be "Stockholm Syndromed" against Jennifer.

I imagine she stashed the girl at some safe place, or quickly returned her to Mom before meeting the Sheriff. Not a lot of time passed and this would be possible.

Unless she was so severely traumatized that it transformed her into a ruthless murderer I doubt it.

*I know that I am stupid but when I look around me I feel a lot better.*

Yes she killed her.

NO. I am still alive and I am searching for Jennifer for my revenge.
