A retired British murder squad detective has put together what he claims is an image of Jack The Ripper - the unidentified serial killer who terrorized London in the 1880s.
Trevor Marriott created an e-fit of the man he believes was the responsible for the Ripper murders, a German merchant named Carl Feigenbaum, for a BBC television program.
Feigenbaum was a suspect at the time of the murders, and reportedly told his lawyer that he had a "desire to kill and mutilate every woman who falls in my way." He was later convicted of killing his landlady in Manhattan, and died in the electric chair in New York's Sing Sing prison.
No photographs of Feigenbaum exist, so the e-fit (an electronic artist's impression) was based on eyewitness descriptions.
There are hundreds of suspects who have been investigated by sleuths through the years, but no-one has ever been able to conclusively prove the killer's identity.
This is not the first time that experts have attempted to use modern policing techniques to identify the Ripper. In 2006, Scotland Yard experts created this e-fit of what they thought the Ripper would look like.
