Has the Mystery of Jack the Ripper's Identity Finally Been Solved?

Crime buffs have used advanced DNA analysis techniques to reveal what they claim is the true identity of Jack the Ripper: a Polish immigrant called Aaron Kosminski. Businessman Russell Edwards, who describes himself as an "armchair detective", bought the scarf. It belonged to the Ripper's fourth victim, Catherine Eddowes, and was discovered by police close to her mutilated body at the murder scene. Edwards sent the scarf to Dr Jari Louhelainen, a senior lecturer of molecular biology at Liverpool John Moores University.
