Jack the Ripper Identified?

Claim:   The identity of notorious murderer 'Jack the Ripper' has finally been definitively established.

UNPROVEN

Origins:   In September 2014, the British press (and then the American press) trumpeted the news that the notorious case of late 19th century murderer Jack the Ripper had at long last been definitively solved, and the identity of the killer had been established through DNA testing as a 23 year old Polish immigrant named Aaron Kosminski:

Russell Edwards claims Aaron Kosminski, a 23 year-old Polish immigrant who ended up dying in an asylum, was "definitely, categorically and absolutely" the man behind the grisly killing spree in 1888 in London's East End.

Edwards said a blood-stained shawl he bought in 2007 after an auction in Bury St Edmunds, Suffolk, held vital DNA evidence which led him to the killer.

"I've got the only piece of forensic evidence in the whole history of the case," he said. "I've spent 14 years working on it, and we have definitively solved the mystery of who Jack the Ripper was."

"Only non-believers that want to perpetuate the myth will doubt. This is it now — we have unmasked him."
