At some unknown point this demon possessed a cop. While possessing the cop the demon kept a lookout for Sam and Dean Winchester who were trying to kill Lilith and get Dean out of his crossroads deal. When the demon first caught sight of the Winchesters this demon pulled them over. The demon approached the car to talk to the boys. Dean attacks the officer and stabs him with Ruby's knife, revealing he's really a demon to Sam. Dean confesses he saw his real face under the human face and that is why he attacked him. The boys and Bobby Singer later hide the body and cop car.
