Introduction by Aaron Kozminsk

Aaron Kozminsk aaron kosminski (full name: Aaron Mordek Kozminsk aaron mordke kozminsk; 1865-9-1~1919-3-24) is a man who is regarded by some people as Jack the Ripper, a serial killer in London (now confirmed). From 2065438 to September 2004, Russell Edwards, a British businessman, claimed that he had proved cosmi's guilt with mitochondrial DNA evidence, although his statement was not confirmed by the publication and peer review process. Cosmi's base immigrated from Poland to England in A.D. 1880, and worked in Whitechapel in East London, where he committed a crime. 189 1, he was sent to a mental hospital. Judging from the time of the murder, the police pointed out that one of the suspects was "cosmi Ski" (no name was given) and described him as a Polish Jew in a mental hospital. Almost a century has passed since the last murder. The suspect "cosmi" was identified as aaron kozminsk, but there was no evidence to link him with the murder, and the reason why the police regarded him as a suspect at that time was unclear. It is possible that cosmi Ski is confused with another violent patient of the same age, Aaron or David Cohen, who is a Polish Jew whose real name may be Nathan Kaminsky.
