based on this analysis, he said, "it's possible the Ripper could be female".

Based on this quote I've concluded that the Ripper was either male or female. Startling information indeed.

My prior would be p=0.167 (cite: Wikipedia, "one out of every six serial killers is a woman").

That's still way too high (after conditioning on the nature of the murders). Most all female serial killers are angels.

This is why they should give names like Chris to unknown serial killers.

No. Using undiscovered evidence, I've pieced together the facts to uncover that Jack the Ripper was, in fact, the Loch Ness Monster.

does not compute, Loch Ness Monster lives in Scotland and Jack the Ripper lives in London.

+ the loch ness monster is huge..there is no way he could have sneaked up on someone to stab them.

Don't really see what this has to do with startups or technology

What I learn for my startup : say something shocking about an unsolved mystery and gain attention for free.
