IMO If she were still alive when medics arrived there would be evidence they had been working on her left behind around and on her body. I see no evidence of that. If she was actually breathing or had a pulse when they arrived she would likely have been trasported to a trauma center. You can't effectively do CPR on a victim if the victims hands are bound behind their back. IMO She wasn't "in distress" when medics arrived she was dead, VERY dead.
