I think that an often overlooked detail in the comparison between the Ripper/Torso cases is that both of the series started back up around the same time in 1889, and both seemingly ended in the same year. Personally, I'm unconvinced McKenzie was a Ripper victim but she's the last victim that meets the criteria (throat cut, body mutilated). Does this hold any significance? It would be statistically rare for two serial killers to be active in the same locality at the same time. What are the odds that the both of them reemerged after a long layoff? Unless one was motivation for the other?
