Legal Question in Criminal Law in Arizona

I'm not going to advise you as to whether she should or should not talk to the police, without knowing more (and I would not suggest you post more facts on a forum like this). However, she is not required to talk to anyone about anything unless she is under a court order. If she does talk to the authorities however she must be truthful. She may want to directly and personally consult a lawyer to discuss the details and options. Good luck.
