LONDON, ENGLAND - You don't know Jack? Well, now somebody finally says they do! A new book claims to have unmasked Jack the Ripper, a whopping 126 years after his grisly murders were committed.

Back in London's East End, 1888, five women were brutally killed by a criminal cops called Jack the Ripper. His real identity has remained a mystery, possibly until now. In the book "Naming Jack the Ripper", author Russell Edwards I.D's a 23-year-old Polish immigrant named Aaron Kosminski as the notorious 19th century slasher, all done with the help of DNA evidence.

On a shawl worn by one of the victims, scientists were able analyze stains on the bloody scarf and what they found shocked them. Human sperm stains. So it looks like a knife wasn't the only thing Jack was wielding when he attacked the women. Sick, but at least now we know.

Then these modern-day Sherlock Holmes had to track down a distant descendant of Kosminski living today, to make sure their DNA matched what was found on the shawl. It did. So one of the world's most infamous murder mysteries may have been solved, all because Jack the Ripper put a little too much of himself into his work.
