After living with the perp in a two man tent for days ... could;t she have alerted the horseback riders?
She was raped. No?
Yes she could have. He might have convinced her he would shoot anyone she told. Or her. Or both.
Remember Elizabeth Smart? While in captivity she would walk on the public street and into stores with her abductor yet not say a word to anyone. I imagine they are terrorized into staying silent.
