I did a little research on embalming. It is not legally required. https://www.funerals.org/fr…

So, Norman didn't want his mother embalmed. But, they "prepared the body." What does that mean? Is this even legal? Norman and Sable will get together sometime in S5, for sure.

Did anyone notice that Norman buried a black suitcase, but when he found the suitcase in the basement, it was a brown suitcase? In S4, Ep 9. Not sure if this means anything, but I did notice.

But, they could have found Norman's fingerprints on the vents, but Norma's would probably not have been on every vent. So, then, the police would question who was the murderer and who committed suicide.
