The Ripper, far from being the savage, messy slasher of popular myth, was a calm and careful killer. Rather than simply lunging at victims with his knife, he would first choke them and lay them quietly down before commencing the evisceration. This is part of the reason he didn’t alert anyone within earshot to what was going on. Holmes, too, had a methodical killing style, and was also a trained medic – meaning he was adept at the removal of organs. Of course, one of the most widely held beliefs about Jack the Ripper is that he had some degree of medical training. It’s also important to consider that the last of the official, canonical victims of Jack the Ripper was killed in her own bed rather than on the streets. And she wasn’t simply cut open. She was utterly obliterated by the Ripper’s blade, to the point of being almost unrecognizable. This was a huge escalation from the previous Ripper killings, both in terms of context and ferocity. In other words, Jack’s style had evolved. If Amaryllis Fox’s theory is right, this could have been Holmes trying out different methods, and moving towards the more grandiose style he displayed in the Chicago Murder Castle. Holmes left a trail of business documents which allows us to chart his movements. Except, that is, between 1888 and 1889, when the paper trail goes mysteriously quiet. This coincides with the timeframe of the Ripper killings in London – so could this have been when Holmes was Jack? We do know from ship logs that an individual by the name of “H Holmes” was a passenger who sailed from the UK to the US shortly after the Ripper killings ended. There’s more. Linguistics experts consulted by Mudgett and Fox carefully analysed the “Dear Boss” letter, widely regarded as having been sent by Jack to the London media of the time. The expert confirmed that various quirks of language suggest the writer of the letter was American. Mudgett and Fox also commissioned a forensic sketch artist to create a portrait of Jack based on witness testimonies of 13 people who’d seen the Ripper victims with men just before they died. The result? A portrait so similar to photos of HH Holmes that Mudgett – an attorney by trade – firmly believes it would merit an arrest warrant if the case was active today. Fox agreed. Link to report of findings I understand where people say it's not possible. But I also saw the evidence saying he is. The evidence to him being the ripper is getting more and more towards being proven. I was just curious what others thought.
