" The notorious serial killer who stalked London's East End, butchering prostitutes and terrorising the population, may not have been Jack the Ripper - but Jill.
An Australian scientist has used swabs from letters supposedly sent to police by the Ripper to build a partial DNA profile of the killer. The results suggest that the person who murdered and mutilated at least five women from 1888 onwards may have been a woman.
Ian Findlay, a professor of molecular and forensic diagnostics, told the Australian Broadcasting Corporation that he had developed a profiling technique that could extract DNA from a single cell or strand of hair up to 160 years old. Conventional DNA sampling methods require at least 200 cells."
