Cain, the First Serial Killer!
Here's the Jack the Ripper message board at GameFaqs.

People are wondering about the game. What sort of game could this be, they wonder?

-Could it possibly be based on the secret attack of Disgaea?
-Was Jack the Ripper really a vampire or a witch?
-Morrissey?
-A publicity stunt to boost tourism?
-Or to look 'tuff' like those Yanks?
-And Cain! The original serial killer!

Watch and be amazed as a message board of finds out who Jack the Ripper was!

Or not.

I might have posted somewhere in there. Or maybe it WAS JACK THE RIPPER!
(I wish I could make this shit up.)

My favorite line:
yes publicity because they prolly wanted to look all tuff like america to show that they had some tuff people their also, or that they had their huge crimes also.
the world may never no, well except for london</a>
