I'm going to maintain an open mind about this one. For the following reasons:
1) The estate has been handling the money well because they have a vested interest to do so. They get 10% (or at least 10%) of all of the earnings coming in on top of their billable hours. Not bad.
2) I still believe that Randy is the one brother that I am sure of is in on the hoax. He won Michael's trust during the trail and when he suggested that he hire Messereau. He doesn't believe the will is valid and neither did Katherine...until she found out that if she contests the will, she jeopardizes her share. Randy's point is valid, Michael wasn't even in CA when the will was signed.
3) Just because "they" found Branca not involved in one particular instant, doesn't mean that there weren't other issues. Michael had reason to be suspicious. There had to be something else.
Until the will is validated, I'm not 100% about anybody. The whole estate is based on the validity of the will.
That's too big of an issue to just ignore.
One possibility....maybe this is part of Michael's big lasso that will "trap" everyone involved.
I'm one of those who doesn't have enough proof yet to know what the truth is.
