Hi,
As some of you have noticed, I published a list with useful and necessary criteria for hypothesizing about who Jack the Ripper was or could have been.
The reason for the list is the need for historical coherence as well as reliability and validity in any hypothesis about the killer.
But there may also be some items missing on this list.
And there are certainly problems with each item.
So two questions:
1. What is missing?
2. What problems do each item imply?
(For hypothesizing about who Jack the Ripper was, there should be):
1. Time periods in a personīs life matching the time periods for starting, stopping, starting again and finally stopping (or just once if that is what you have).
2. A clear motive distinctly connected to these points in time.
3. A clear motive connected to the choice of murder dates.
4. Sources indicating that he was at the crime scenes.
5. Sources showing he had the skills to do what the killer did.
6. Historical sources explaining why he was not caught.
7. Historical sources explaining why the sources giving his motive, time periods, skills, and so on and so forth, exist.
8. Historical sources explaining the unexplained sources in the case.
9. It has to shed light on everything.
10. A confession. (I have added this item here).
With these items I think you would have an historical case.
Regards, Pierre
