I believe it's more likely that the official site for the film contains an incorrect spelling of the surname of the two protagonists. At 00:02:02 in the film, the interior shot of Judy's office displays her title on the door as "Dr. Judy Dutten". Also, at 00:08:42 in the film, David is sitting at his desk with a name placard declaring "Sheriff Dutten". Furthermore, the film's credits do not include last names.
