Shannon Quinn says, Meet Aaron Kosminski—AKA Jack The Ripper; 10 Reasons We Know It Was Him, in her post at Listverse.  Here are my choices for her three strongests arguments that Kosminski was the Ripper…

The DNA Evidence
A shawl that belonged to Jack the Ripper’s fourth victim, Catherine Eddowes, was purchased by a man named Russell Edwards in 2007. He was so determined to figure out the identity of the killer, that he had the shawl tested for DNA in 2014. This genetic material was traced back to one of Aaron Kosminski’s living relatives. Edwards was also the author of a book called Naming Jack the Ripper, where he lays out his analysis of the case over decades of research.

However, there were claims that the scientist who analyzed the DNA, Jari Louhelainen, made a mistake in his analysis. Critics refused to recognize the DNA evidence until it was scrutinized in a peer-reviewed journal by other scientists who had nothing to gain from the results. In 2019, the data had, in fact, been published in The Journal of Forensic Sciences. It was confirmed that the DNA did, in fact, belong to Kosminski. However, critics still refuse to believe that accurate DNA evidence could exist on the shawl without contamination for over 100 years.[1]

He Had a Deep Hatred Towards Women
In modern studies of serial killers, one of the common threads is a deep-seated hatred towards women. This comes from a percieved notion that women are withholding sex from them after a string of female rejections throughout their life. They also may have had a terrible relationship with their mother. Jack the Ripper chose sex workers as his victims, and he removed the organs of these women. One of his victim’s faces was brutally savaged, showing that he was full of an irrational rage against this woman who he did not know.

Aaron Kosminski was 23 years old at the time of the first murder. He never married, and had very bad luck socializing with ladies. According to Meville Macnaghten, the chief constable of Scotland Yard, Kosminski was known for having a deep hatred towards women. Macnaghten wrote, “This man became insane owing to many years indulgence in solitary vices. He had a great hatred of women, especially of the prostitute class, & had strong homicidal tendencies.”[4]

Kosminski Was Put Into An Insane Asylum
In 1891, Aaron Kosminski was confined to the Colney Hatch Asylum. The 5 “canonical murders” which have been officially credited to Jack the Ripper stopped soon after. Cambridge University has copies of Aaron Kosminski’s psychiatric records from the time he spent in the facility. According to the records, he heard auditory hallucinations that told him to do things. “He declares that he is guided and his movements altogether controlled by an instinct that informs his mind.” The documents also state that Kosminski grabbed a knife and threatened to slit his sister’s throat. It was clear to everyone, even his doctors, that he hated all women.

Modern doctors have diagnosed him with paranoid schizophrenia. Some people have tried to claim that Aaron Kosminski was not a violent person, and that he was more inclined to act out in self-harm. He also refused to eat, for fear of being poisoned. So he would pick scraps of food out of the gutter, instead. However, according to Cambridge University, the references to “self-harm” were actually talking about frequent masterbation. And while he may not have been violent towards the other men in the asylum, he still has a record of violence towards women.[8]

Kosminski is just one of several suspected of being Jack the Ripper.  It’s hard to argue with DNA evidence… but then again, Patricia Cornwell’s theory that Walter Sickert was Jack the Ripper also had DNA evidence!
