McDabble was a victim of the clown, but also a suspect of taking the ruby himself because he wanted to close the carnival early, and because of the box he had was believed to had contained the ruby inside. (It was only the prize for the raffle, a watch he didn't want to get wet while he played target for the carnival dunk tank).
