At the County Court House, Dr. Richmond explains to Lila Crane, Sam Loomis, Deputy Sheriff Al Chambers, Deputy District Attorney Alan Deats and Chief of Police James Mitchell that he knows what happened, but it wasn't Norman Bates who told him. He explains that Norman, as his mother, murdered not only Marion Crane and Arbogast, but also two young women. He says that Norman became troubled after his father died and murdered his mother and her new husband when he became jealous. He then started murdering women who he became attracted to as his jealous mother. He ends the conversation by saying Norman's mother has become the dominant personality and Norman no longer exists.
