Question: Spoiler alert: this question gives away much of the first "Psycho" movie. In the original Alfred Hitchcock "Psycho" we witness Norman Bates murdering Janet Leigh/Marion Crane and Martin Balsam/Milton Arbogast, and very narrowly missing killing Vera Miles/Lila Crane. At the end of the movie we discover that Norman Bates had murdered his mother and her lover ten years previously. We are also told that he had killed two female guests at Bates Motel. Norman Bates is therefore guilty of six murders and one attempted murder. In Psycho II we find out that, after his crimes were discovered, Norman Bates was placed in a secure psychiatric institution for the criminally insane. This does seem plausible. But with such a criminal record, would he ever be released from incarceration?
Question: Who was doing the killings before Norman finally snapped?
Chosen answer: The murderer is Emma Spool, Norman's biological mother. She was killing people because she didn't want anybody harming Norman.
Emma was not Norman's biological mother. She was the sister of Norma (and Norman's aunt) and jealous that Mr. Bates chose Norma over her and thought Norman should have been the son she and Mr. Bates were suppose to have. Later, while still mentally ill, she believed Norman was her son and told Norman this.
Emma Spool was, in fact, Norman's biological mother. It was revealed at the end of the movie that she is his real mother and Norma Bates is her sister who adopted Norman and raised him While Emma was institutionalized.
Again, that was just Emma being delusional and/or lying. Tracy Venable tells Norman the truth in Psycho III. Emma was never his mother.
I never knew Emma Spool was Norman's biological mother. In fact, I never heard of Emma Spool. Thanks.
Answer: Norman was found "not guilty" by reason of insanity. Therefore, once he is deemed to be no longer a danger to himself, or to others, and is released from the mental institution, there is no crime he can be sent to jail for (i.e. he has no criminal record for the murders). I haven't done enough research to tell you if a serial killer in recent times has ever been found not guilty by reason of insanity and subsequently been released, but there are numerous accounts of people being released from mental institutions after committing murder that are then considered free.
