Laura Richards of Scotland Yard assembled a team to apply 21st-century profiling methods to the unsolved Jack the Ripper murders.
Ms Richards said the 118-year-old evidence shows the Ripper was between the ages of 25 and 35, between 5ft 5ins and 5ft 7ins tall. He was also of stocky build.I ran Jack's composite sketch through the facial-recognition software at MyHeritage.com to determine which celebrities are most likely descendants of the murderer. The leading candidate: David Schwimmer, a 66% match who suspiciously dropped out of sight following the final episode of Friends.
Investigators have even been able to pinpoint his address.
Ms Richards said: "For the first time, we are able to understand the kind of person Jack the Ripper was.
"We can name the street where he probably lived; and we can see what he looked like; and we can explain, finally, why this killer eluded justice." [Link, via Family Research]
