What do we think could be the theoretical and practical problems or possibilities if we state that the killer came from an upper or lower class - or that he was well educated or not?
Would this have relevance for his motives? Murder methods? Choice of dates? Chance to escape the police? Chance to plan the murders? Etc.
I think I know that he was well educated and that he lived for a short time in a house that looked a bit like this one:
If he did, he must have had a lot of resources to spend and could have chosen any victims or dates. So why make the choices he did?
I will get back to that question.
