Wait, wait wait.... you need to clarify that one line--she liked it?
Regardless, be there for her. How well do you know her? If it is more than an acquaintance thing, forget the phone call, go see her (unless you think that she would feel awkward or embarassed).
Is she going to the police? Has she told her family?
I wish her (and your friend, and you for that matter) luck--thats a shitty situation to be in
