According, to what i read here is exactly how that "wealth thing" was going:

1. old man died, she gets sued because, well you know...
2. She gets awarded $457 million out of about $550 million...
3. Decicion gets over turned...
4. Stepson dies...
5. Case gets revived...
6. Still in process..
7. Anna's sudden death...

So im sure she lived well, but i dont think she had all the money, people think she "inherited"
