I'm guessing that her worst fear was realized: Someone saw the pictures and recognized her, and told her about them. I can't process the logistics of how that happened without the person getting arrested... Or how it could happen without a pedophile in the mix... But I can't think of any other way for her to find out. Edit: I suppose it's possible that the police found the images, managed to identify her, and felt it was their responsibility to inform her.
