Not sure how reliable this website is (those who live in the UK would know better then I would) but this article says they have identified who The Ripper was using DNA tests. He is supposed to be Aaron Kosminkski, a 23 year old man from Poland. Police at the time had suspected him as the killer, but didn't have enough evidence to arrest him. Blood found on a shawl was identified as his. Didn't know dried blood would hold up well enough after all these years to be tested, then traced through his relatives living today.
