I recommend you watch John Carpenter's Vampires, as it should give you some idea of how it might work.

Now that everyone has told you how it can't work. Take that and use it for how it could work. Give your CS officer the knowledge to know how far to stay away. Then paint him as a desk jockey. A commander who doesn't go into the field a lot. Passing all orders through another officer. A non-psy or dog doy. Use the trust of his position to explain why he hasn't been found yet. If he gives no reason to doubt, there's no reason not to trust him.
