And it was those prostitutes that Jack preyed upon: he murdered at least five of them. But what made this serial killer so utterly horrifying is what he did to his victims while slaughtering them. He sliced them open, leaving terrible wounds, and in some cases is even said to have removed various internal organs.
In the 130 years or so since the murders were committed, though, more than 100 people have been named as possible suspects. Many of those have been quickly refuted by investigators, but others retain at least some claims to plausibility. And so frenzied has speculation been over the decades that those obsessed with the crimes have been dubbed Ripperologists.
One author and Ripperologist, Richard Wallace, even claimed in a 1996 book that a certain Charles Lutwidge Dodgson was the murderer. Dodgson is better known by his pen name Lewis Carroll and is the author of Alice’s Adventures in Wonderland. Wallace based his widely-disregarded claims on anagrams constructed from Carroll’s literary output.
