The Dr Oz therapist also spoke about this might have happened because there was some 'big secret' about to come out and the mother was trying to protect her kids from that (plus mentally ill).
Her company only had 1 employee but it only had $ 200,000 gross sales IIRC. The mother had been nominated for the top 100 business women of the year. Most people have a little humility and don't publicize every award or trophy that they or the children receive but she did. She made sure to document every time that she took a plane from one location to another and all of the high-end restaurants , art shows, super bowls, baseball games, prom queens, politician and celebrity photos, the benefitis and ball gowns etc etc.
She lived in a 4 story townhouse in a gated community and flew all over the world.
Her daughter's heart was in NY and they all knew that she wasn't moving back to Atlanta.
We don't know the precise reason why but I believe that we can make some great guesses.
Unfortunately, there should be public records regarding her company and income and I don't think those records are public.
