At some point, he joined the army and was a member of the Green Berets. He also collected several weapons, as well as started his own security firm. He also had a pet Rottweiler dog, which he was led to believe was a prized showdog. Grayson was later murdered by the same person later on, by taking his Rottweiler to Waters' garage to lure him to the garage and then fatally hit him with a shovel, which also cleared his name as a suspect. The murders were later revealed to have been committed by Tod Katterskill.
