Now , one of the instance ’s first suspect is back in the news . AsSmithsonianreports , Aaron Kosminski , a barber from Poland , has been relate to the Jack the Ripper murder with DNA grounds — but experts are hesitant to call the font close .

The new title come from datum now published in theJournal of Forensic Science . Several years ago , Ripperologist Russell Edwards expect researchers from the University of Leeds and John Moores University in Liverpool to analyze a stock - stain silk shawl believe to have belonged to Ripper victim Catherine Eddowes . The detail , which Edwards own , has been a primary piece of grounds in the execution investigation for years . In 2014 , Edwards write a book in which he claim Aaron Kosminski ’s DNA had been found on the garment , but his results were n’t published in a compeer - review journal .

Five years later , the researchers have released their determination . Using infrared and spectrophotometry technology , they confirm the fabric was sully with blood and discover a potential semen stain . They collected DNA fragments from the stain and compare them to DNA taken from a descendent of Eddowes and a descendent of Kosminski . The mitochondrial DNA ( the DNA passed down from mother to materialisation ) extracted from the shawl containedmatching profilesfor both subjects .
