Researchers say they have DNA proof of the ID of Jack the Ripper.
Forensic scientists say Aaron Kosminski, a 23-year-old Polish barber, murdered at least five women in London in 1888. They claim they were able to match DNA found on a silk shawl stained with blood and semen to living relatives of Kosminski.
Although experts have long listed Kosminski as a suspect, this is the first time forensic evidence has linked him to one of the murders. (USA Today)
