With a slight modification the theory becomes a lot less silly. Suppose that Mary Kelly and Joseph Barnett killed a woman and mutilated her so that she couldn't be properly identified, and thus pass for MJK. After all, only Barnett was able to identify the corpse, and apparently he could only do so from the eyes. The eyes, without eyelids - meaning they wouldn't have looked like MJK's eyes at all, whether that was the real MJK or not
The police would have no motive for arranging such a hoax, but MJK might, for personal reasons. This would also explain why Caroline Maxwell insists she saw MJK hours after the proposed time of death. It would also explain the facial mutilations, quite different from anything done to previous victims, and these particular mutilations almost seem to have been made specifically to complicate identification.
This is a theory that I don't dismiss, rather than a theory I believe. It's mostly conjecture. I don't buy MJK as a Ripper victim in any event, though.
Well my original idea was also based around the sighting of Kelly, the murder being indoors instead of on the street, the long gap between Eddowes and Kelly'so murders, the strange going on's at the inquest and that blasted key and kicking the door down fiasco.
But the only motive I could come up with for a Police put up job, was simply a training exercise in future such events....ie crime scene detection.
As I say, just a thought.
With the 100+ suspects we have, we have some "Gentlemen", for instance, the Queens Grandson, Gull, Druitt and others.
Think about it, unless there really were two of them, who the hell would want to hang around Bucks row, Dorset st and so on, considering they were supposed to be mean streets, lowest of the low and so on, could you see any of the aforementioned hanging around these place late at night, I wouldn't do it nowadays let alone back then.
Even though armed with sharp knives and so on, could someone like, well, any of them, take on a hardened Eastender or thug?
I suggest not, not forgetting of course that they could also run into one of the gangs in the area.
Surely, JTR had good knowledge of the area, came from the area, lived in the area?
This we know to be the likeliest type of candidate anyway, I think we all know that it was highly likely NOT one of the above or anyone like them.
Hasn't it got to be the roughest toughest suspect on the block, or just one of the many Sailors who can kill and then, vanish at will?
If we discount the "Gentlemen" types and the honest working class type who have no time for this sort of thing then, what are we left with?
How about the idea that a group of landlords decided to off some prostitutes near their properties so they could charge people to look at the crime scene. Made money out of a crime museum of sorts by committing the crimes. Hanbury St owners made a killing...
Bona fide canonical and then some.
