Kosminski was previously named as a suspect over 100 years ago and again in a 2014 book called British Businessman and Ripper Researcher Russell Edwards. However, the latest finding marks the first time that Edward's DNA evidence has been published in a peer-reviewed journal, according to a journal Science.
"To our knowledge, this is to date the most advanced study in this case." The authors of the study wrote.
Jack the Ripper is said to have killed at least five women between August and November 1888 in London's Whitechapel district. Researchers Jari Louhelainen and David Miller performed genetic tests on a blood-dyed silk scarf According to investigators, semen was found next to the body of the murderer's fourth victim, Catherine Eddowes, Science reported.
The researchers compared fragments of mitochondrial DNA – inherited from a mother according to the magazine – with samples from living relatives of Eddowes and Kosminski and found that they matched those of Kosminski's relatives.
The study also includes an analysis of the killer's appearance, which suggests that the killer had a brother wn hair and brown eyes. This is consistent with the only reliable testimony, according to Science.
The results of the study can not satisfy other Ripper experts who said the cloth may have been contaminated over the years. The scarf was given to Louhelainen by Edwards, a self-proclaimed "secret detective" and author of "Naming Jack the Ripper," who bought it at an auction in 2007, according to Guardian.
Just a piece of forensic evidence throughout the history of the case, "he told the newspaper in 2014." I've been working on it for 14 years and we've definitely solved the mystery of who Jack the Ripper was.
