Researchers tested blood and semen found on a shawl near the body of the killer’s fourth victim, a woman whose mutilated body was found in September 1888.
The identity of Jack the Ripper, the notorious serial killer from the late 1800s in England, may finally be known.
A DNA forensic investigation published this month by two British researchers in the Journal of Forensic Science identifies Aaron Kosminski, a 23-year-old Polish barber and prime suspect at the time, as the likely killer.
The “semen stains match the sequences of one of the main police suspects, Aaron Kosminski,” said the study authored by Jari Louhelainen of Liverpool John Moores University and David Miller of the University of Leeds.
