Finding Jack the Ripper - DVD

Could Jack the Ripper have been the world's first trans-Atlantic serial killer? Can 21st century techniques and CGI 3-D autopsies crack this 19th century crime spree, while reversing decades of investigative assumptions? National Geographic joins retired U.K. murder squad detective Trevor Marriott to finally unmask the Ripper and possibly link him to other murders in Europe and the U.S.
