Who was Jack the Ripper? Show more Show less
Back to question

Jack the Ripper was one of the most notorious serial killers in history. In 1888, the Ripper was suspected of brutally killing at least five women in and around the Whitechapel district in the East End of London. The Ripper killings were the focus of an intensive police investigation and garnered enormous attention from the public and media, but the case went unsolved, and the identity of the Ripper remains a subject of widespread debate over a century later. So who was Jack the Ripper? Was he one of the contemporaneous suspects, or one revealed by historical and scientific research? Was he even a man - or, for that matter, was he real at all?

The Argument

The Ripper case remained unsolved for over a century after the murders, but scientific and historical interest in Jack the Ripper did not disappear even after the Ripper and all others involved in the case had died. In 2019, a peer-reviewed study was published in the Journal of Forensic Sciences based on DNA analysis of samples taken from a shawl found near the body of Jack the Ripper's fourth canonical victim, Catherine Eddowes. The genetic analysis indicated a match between the mitochondrial DNA found on the shawl and the DNA of Ripper suspect Aaron Kosminski. This hard physical evidence indicates that Kosminski was Jack the Ripper.
