One of the many intriguing aspects of the Ripper killings is the way that the killer managed to savagely murder the victims and leave the scene unseen, unheard.
Even on those occasions when the murderer was possibly seen by witnesses, he showed no great nervousness, or even an attempt to hide or minimise his presence.
Indeed, he even found time to shout at Israel Schwartz just prior to the probable murder of Liz Stride.
There is no evidence that the murderer fled panic stricken from the scene of any of the crimes. No one saw anyone running or leaving hurriedly from any of the crime scenes. No one heard anyone running from any of the crime scenes.
Why the coolness under pressure?
Even those killers convinced of the moral justification of their actions have an aversion to facing the execution chamber.
Using the established facts, can we reasonably speculate as to the reasons why the killer appeared to be so untroubled about the possibility of being caught in the act, or being seen and heard leaving the crime scenes?
In July 1890, Aaron was taken to Mile End Old Town Workhouse probably because he was exhibiting sign of mental instability, his admission papers say “Qy Insane” (Query Insane).
He was discharged on 15th July 1890.
Fast forward to 4th February 1891 and we find Aaron being readmitted to Mile End Old Town Workouse. He was examined by Dr Houchin on 6th July 1891 and declared insane.
Dr Houchins report on Aaron gives us his views about the patients mental state, and says specifically, “He declares that he is guided and his movements altogether controlled by an instinct that informs his mind; he says that he "knows the movements of all mankind” (my emphasis).
If Aaron Kosminski was the killer, does Dr Houchin’s report give us a reason for the killers apparent coolness while carrying out the crimes, and his apparently unhurried leaving of the crime scenes?
What I am speculating is that possibly Aaron knew for sure we that he was not going to be caught because his voices told him where everyone was, including the local beat constables.
It could also explain why so many of the murder sites were in plain sight.
He could kill calmly and without fear of being caught afterwards.
He had nothing to fear, no need to rush, to need to run from any of the murder scenes.
This was a killer operating with supreme confidence.
This does of course depend on Aaron knowing “the movements of all mankind” in late 1888, but I think it is an idea worth exploring.
I am not being dogmatic about any of the above, I am merely throwing an idea out there.
We know very little about Kosminski, and it struck me that perhaps Dr Houchin’s report has been overlooked in regard to what could be an important clue.
