they must have found her body, and haven’t released the details yet. they wouldn’t be just arresting these guys again for no reason.
They must have reason to arrest them, one could assume, but finding her body isn’t necessary. That is all to the good, because I will be surprised if there is anything left of her to find. If they did find something, then that would be even better than one could have hoped for.
I wouldn’t put money on it.
