Captain's log - Stardate 2261.414
Bones discovered that the old man had a device implanted in his skull and, from the condition of the brain matter closest to it, he believes that is what killed him. He was about to perform a little surgery to remove the device when we were swarmed and overpowered by over a dozen armed men.
I woke to find Spock kneeling beside me. He and I were in the same area, but the body of the old man had been removed and Bones was missing. I need to stop allowing him off the ship.
