Sam Loomis
Background
Sam Loomis owns Sam Loomis Hardware in Fairvale, California. He is in a relationship with Marion Crane and has an ex-wife.
During the events of Psycho (1960) played by John Gavin
Marion and Sam are at a hotel room. Marion tells Sam that she has to get back to work and tells him the next time they meet, it should be at her and Lila Crane's house. He tells her that he wants to be with her and is tired of sweating to pay off his dead father's debts and his ex-wife's alimony. He says that in a couple of years his debts will be paid off. A week later, Sam is writing Marion a letter as a customer is reading the ingredients off the back of an insecticide can to Bob Summerfield. Lila walks into the store and asks to speak with Sam. She asks him if Marion is there and says Marion is missing. Sam sends Bob away for lunch. Arbogast walks into the store and tells Sam that Marion stole 40 thousand dollars. He tells him and Lila that be believes Marion is in town somewhere and leaves. Arbogast calls Sam's store and asks to speak with Lila. He tells her that Marion was at Bates Motel and he was going back to the motel and will see her in an hour.
Sam goes to Bates Motel and looks for Arbogast and then returns back to his store. He and Lila go to speak with Deputy Sheriff Al Chambers and he tells Al that Arbogast went to the motel to speak with the woman who lives there and Mrs. Chambers assumes he means Norman Bates got married. He and Lila tell the rest of what happened and Al tells them he thinks Arbogast found out where Marion and the money went and went after her. Al calls Norman and Norman tells him Arbogast went to the motel and then left. Al hangs up the phone and tells Lila that Norman's mother has been dead for ten years. He tells her that Norman's mother poisoned her new husband and then herself. The next day, Lila and Sam drive to the motel and get a room from Norman. They sneak into the room Marion was at and search it and find a piece of paper with the number 40,000 on it. Lila goes to the house while Sam goes to keep Norman occupied. Norman and Sam get into a fight and Norman hits Sam in the head with a jar and runs to the house. Norman, dressed in a dress and wig and carrying a knife charges at Marion. Sam grabs Norman and stops him. Later at the County Court House, Dr. Richmond explains to Lila, Sam, Al, Deputy District Attorney Alan Deats and Chief of Police James Mitchell that he knows what happened, but it wasn't Norman who told him. He explains that Norman, as his mother, murdered not only Marion 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.
