Arron Kosminski, the suspect hinted as being Jack the Ripper, by Sir Melvlle MacNaughton as being the most likely suspect. Also, the subject chosen by Author Russell Edwards, who bought the shawl in 2007 Results from a forensic examination of this stained silk shawl that investigators claim was found next to the mutilated body of Catherine Eddowes, the killer’s fourth victim, in 1888. The shawl is speckled with what is claimed to be blood and semen, the latter believed to be from the killer.
This isn’t the first time Kosminski has been linked to the crimes. However, it's the first time the supporting DNA evidence has been published. The first genetic tests on shawl samples were conducted several years ago by Jari Louhelainen, a biochemist at Liverpool John Moores University in the United Kingdom. Edwards used the unpublished results of the tests to identify Kosminski as the murderer in a 2014 book called Naming Jack the Ripper. But geneticists complained at the time that it was impossible to assess the claims because few technical details about the analysis of genetic samples from the shawl were available.
The tests compared fragments of mitochondrial DNA—the portion of DNA inherited only from one’s mother—retrieved from the shawl with samples taken from living descendants of Eddowes and Kosminski.
The DNA matches that of a living relative of Kosminski apparently traced in Poland they now conclude, in an article published in the Journal of Forensic Sciences.
However, these results are unlikely to satisfy critics as the shawl was supposed to have been passed down through a policeman's family after he retrieved it from Mitre Sq. although there is no mention of a shawl listed in her belongings? Would a policeman even back then, be allowed to remove a murder victims belongings from the murder scene? Then again, Kosminski was a schizophrenic, the main symptoms of his illness were not washing and working, also eating rubbish in the gutter, hardly a man a prostitute would pick up anyway and he does not fit any of the descriptions of people who saw men with these women at the time.
