and jumping off to take this thought further, if the estates of Bob and Georgia were structured as I imagine they were, then the adult children/heirs would receive nothing til the time of Bob's death and his estate was distributed through the probate courts.
However, by marrying, Bob threw a monkey wrench into that possibility. Bob married Fontelle. Now if he dies, even if his will has not been changed to provide for her, she could conceivably tie up the estate (with no access for anyone to money til it was resolved) by challenging the will in court. Especially if he had made it known it was his intention to alter his will after marriage to provide for her.
So Bob's disappearance in that regard worked out perfectly in such a manner as to allow the children to seize control of the trust in his absence by conservatorship. In this manner, Bob is not dead so Fontelle cannot challenge his will or make a claim against his estate as his surviving spouse. The children have control of the money.
This right here, in a nutshell explains to me why Bob's family, aside from his widow, seem uninterested in figuring out what happened to Bob or having his case solved. As long as Bob's status does not change from missing to deceased its as if they received the benefit of both the parents estates without Bob being officially dead and without Fontelle having a legal claim as his widow with which to challenge his will.
