Hi Simon. But are you not quoting it out of context? Let’s read it again, adding the preceding line…
“A gentleman, who on the night of the Mitre-Square murder, noticed in Duke-Street, Aldgate, a couple standing under the lamp at the corner of the passage leading to Mitre-Square. The woman was identified as one victim...”
Hold the phone. Really? Is that strictly true?
While there is no doubt that the woman in Mitre-square was indeed Kate Eddowes, the above statement implies that the woman standing under the lamp was also identified as the victim, Kate Eddowes. That’s two different claims.
In truth, Lawende admitted to only seeing the woman’s back, and, taken to the morgue, only stated that Eddowes clothing appeared to be the same as the woman he had seen under the lamp. I'm not sure that qualifies as "the woman was identified" and, whatever he may or may not have scribbled in a margin years later, the contemporary Swanson appears to have been unimpressed.
Thus, I suggest that, if not an outright porkie, it is at least an exaggeration of what had actually occurred.
