Hi Kosminski is never in a million years Jack the Ripper. The killing of Elizabeth Stride was conducted by a man of cunning Kosminski was believed to be a simpleton and would not have the guile to outwit Diemschutz. Its as simple as that I'm afraid. In fact he didnt have the intelligence to outwit anydody if reoprts are to be believed. No for me Jack The Ripper was Robert Mann without a shadow of doubt.

Hello and welcome to the forum!

Depends on how you look at the killing. I am of the opinion that Jack the Ripper was lucky - very lucky. A lot of what he did was sloppy, and the murder of Elizabeth Stride was done in a very risky area. I am not sure whether Diemschutz was the man who disturbed the Ripper as is traditionally thought in this case. A simpler conclusion would be that it was Schwartz who actually stumbled upon the start of the murder, and Jack the Ripper probably made a quick decision to kill her quick and get out of there before he ran to the police, or had the terrible scenario of an eyewitness to give a perfect description of him, as is what would have happened if he had let Liz go.

About Aaron being simple, this was drawn from the asylum records when he was beyond repair from paranoid schizophrenia, thus incarsenated so we do not know what his mind was like in 1888. People with schizophrenia are usually highly intelligent, and just because Aaron was a loner, it doesn't mean he was stupid.
