Captain's log - Stardate 2261.667

Still no sightings of our mystery crewman. If we didn't have proof of his existence, I would have a hard time believing he exists, but the very fact that he is able to evade a thorough search? The only reason for anyone to stay hidden is that they are up to something. And that something is bound to be bad for my ship.

I've continuing all of our increased security measures until he's found. Spock, Sulu and Bones have been removed from duty rotation to dedicate full time to the hunt.
