I don't know how much time you've had to read up about the stun gun theory.. but that was one of Lou Smit's fantasies. He was famous for saying that an investigator doesn't let theory lead to evidence, they let evidence lead them to a theory (paraphrased.. can't find the exact quote). But what he did was counter to his own advice. He formulated a theory in less than a week - well, actually, it was an opinion based on feelings - that the R's were innocent because they were Christians; and then he set about to prove his theory. Even the manufacturer of the stun gun stated that it couldn't have caused those injuries.
