Karen Cooper was the daughter of Harry and Helen Cooper. She was bitten by a zombie when the family's car was attacked, but escaped to the farmhouse. There, she eventually became a zombie herself and ate her father after he died from a gunshot wound, then killed her mother with a garden trowel.
Karen's fate is uncertain. In the film's original ending, she was shown to be the final zombie left alive even after they had burned all the others, but this was deleted for some reason and it is assumed that Karen was killed and burned by the zombie-hunters led by Sheriff McClelland.
