I [former classmate of Roy's, Tom Ashley] called Roy’s wife to express my condolences. I wondered aloud about my conversation with him a few months earlier. “Tom, there was no truth to that,” she said. “Roy was bi-polar and hugely depressed. He
lost his job and felt he couldn’t go on living. Our family wants peace now.”
