Dexter's Kill List (a separate list from The Kill Guide) is a collection of all characters killed by Dexter Morgan, with possible assistance by another character (such as Lumen Pierce). The list unfortunately cannot be placed in an accurate order, as many of the victims were identified during the Bay Harbor Butcher Investigation by FBI Agent Frank Lundy's Task Force. The only kills that can be confirmed in number are those counted back from the time when Dexter confirmed his kills at 67 (who deserved to die by his standards) in Episode 501: My Bad, with Arthur Mitchell being the 67th.
