Captain's log - Stardate 2261.076

Both Craters were acting odd and disappeared while Bones and I were checking in with the ship. We went looking and found the Professor kneeling by Sturgeon's body. I hit him with a heavy stun, but then had to take off after Bones as he was worried about Nancy. She was near the body of Green and seemed to be going to Bones for comforting. That was the last straw - I adjusted my phaser settings and shot her. Not sure who was more shocked when she turned into some weird grey-furred creature.
