Better be a bundle of proof. I honestly didn't dive very far into the story. But I learned more and more that when cases like these come out you will often find cases that jump out of the woodwork and are as fake as a $4 bill. Not to say this girl or any other girl or woman is lying, just what I've seen over time. This is one old case! If someone can even wiggle in there with circumstantial crap, then often some will use money to make things go away. But an accusation like this can't be settled in such a way as then the accusation sticks with you. So Bob is going to have to take this in court all of the way.
No way in hell she wins anything in court without some hard evidence, IMO.
