Ten years before his death, Gary developed a cancerous brain tumor that was successfully treated with radiation. Unfortunately, Gary developed delayed radiaton encephalopathy (swelling of the brain) from the treatment. Gary's two children, both in their thirties and leading active lives with their children, were unable to care for Gary when his health deteriorated. Gary's sister took him into her home so that he would not have to live in a nursing home. After Gary died, his children learned that he had purportedly signed a new Last Will and Testament after he began living with his sister. With that Will, Gary disinherited his children.
