Maybe you don't remember when Jonah wrote a letter to her when she was the state's DA stating that if she thought the investigation was done properly he would have no problem with her judgment. At the time I think that Anne Bremner was the Zahau's attorney. I can't remember the details now, but IIRC she had sent a letter to KH for a review of the investigation and something in her letter upset Jonah and he even sent her some kind of warning about slander or some such.
So, some of us thought he used his wealthy influence on her.
