Here's another view.

Patricia Cornwell and Walter Sickert - a Primer

The evidence is by no means as cut-and-dried as the publicity would have you believe. (It's that old "cui bono" thing again.)

These guys have put together a Jack-the-Ripper website examining the evidence against the various suspects, the witnesses, etc. [WARNING: the crime scene photos are hideously graphic, and I'm speaking as a former arson death investigator.]

If they want to seriously find a DNA sample for the Ripper then they need DNA from Kozminski, because he is still the most likely suspect.

One of the most discrediting facts about this candidate for "Ripper" is that he must have quit doing it and lived many more years after the murders. Most serial killers can't stop once they start. It becomes addicting--and the fact that he didn't tell anyone, write more letters later, etc., doesn't connect with the usual serial killer's ego problems, need for recognition/validation, or ability to stay quiet. This guy also had a big ego so keeping a secret wouldn't be his strongest pesonality trait.

I vote for the nutty butcher, Kosminski, after whose admission to Bedlam (or wherever) the murders ended. Also, the police knew who it was and immeidately after they got him locked up, they quit assigning overtime to the force, as if they were pre-scient in their knowledge that the murders were over.
