Smith is a short man, not much taller than Anita, but his shoulders are broad. Thanks to the combination his jackets always fit him poorly around the shoulders. He has also been known to appear to crime scenes with his collar unbuttoned and without wearing a tie, in contrast to his partner who tends to be neatly but conservatively dressed.
Anita suspects Smith would muscle up easily if he hit the gym enough. He has naturally blond hair.
Smith is part of an experimental program in St. Louis where they pair non-sensitive cops with those who have a measure of psychic ability.
As of Kiss the Dead Smith has a serious girlfriend, although they are having issues.
