My money's still on Druitt.

I have always believed that the British royal family was at least somewhat involved, I also think the theory that Lewis Carroll could have done it. Here is a website that contains almost everything there is on Jack the Ripper.

Montague was always my favorite suspect, especially since his parents told the cops he was the Ripper.

I'd cover my bet by placing some money on "person or presons unkonwn" as well, but yeah Montague John Druitt looks good for it.
