Narrative:

Upon given clearance to land 36L dfw, I noticed another aircraft land on 36L. At 1000', the other aircraft was halfway down 36L. At 500', the captain confirmed with the tower that we were cleared to land. At 200' the other aircraft was still on 36L and I called it out. At approximately 30', the tower called the other aircraft and confirmed he was still on 36L. At that time, the tower told the other aircraft to leave the runway immediately. We landed with the other aircraft still on the runway and beginning his turn off. At no time did the tower give go around instructions. Due to the distance and nighttime operation the other aircraft was extremely difficult to see and was never positively idented.
