The first serial killer !
Maybe he was some kind of genius.If not he was very smart and clever.
I think it could have been a ordinary and miserable worker in factory or something from this kind.I mean he was from the low social classes.He must lived in Whitechapel.To do all of this murders in this hood he had to have a knowledge about each street.This can be only man who lived all of his life in this hood.
MOTIVES : If he had lived in worker or more miserable family his life was very hard there is no doubt in that.Every day he's working and surviving.
But there is high classes and they dont feeling the pain of the miserable life.Jack is seeing in the prostitutes some character of the high classes.
