Finding Jack the Ripper https://g.co/kgs/7QXGyD9

I stumbled on this program recently, a rebroadcast from 2019 of a series called "What on Earth" which usually looks at satellite images of apparent oddities on Earth. These generally have archaeogical or natural explanations.

The episode "Finding Jack the Ripper" focused on an American gentleman named Guy English, a crime profiler specializing in historic serial murders. He used satellite photos of London's East End, as well as historic images and on-the-ground investigation with a Ripper expert named John Bennett.

English's angle seems to be geographic profiling, which I've heard a little about, but don't know very much. He identified Jack as a marader type killer, murdering within a safe known area to his home neighborhood. Starting with the known murder sites of the Five, he established a Kill area, separted by a Buffer zone, then looked at addresses of known suspects. He narrowed the field to 7 possibles within his data, then found the center of the area led to the dwelliing of Nathan Kamisky (aka David Cohen), the violent man who ended up in Colney Hatch.

Very interesting program. Did anyone catch this? Any thoughts?

Hello Pcdunn

Like with criminal profiling - geographical profiling is not an exact science. Not sure also if it wasn't proven that Nathan Kaminsky and David Cohen (Aaron Davis Cohen) are not the same person. Next thing is that Cohen gave his place of residence. Was it not a retreat for poor and homeless Jews?

I guess it might also be difficult to know what is the exact place where Ripper lived as we don't really know (or we aren't sure) who was the first victim and even how many victims there were. Criminal profiling often points that for this kind of killer - he will live in close proximity to first crime. It could be either Polly Nichols or Martha Tabram. In both cases Black Lion Yard (it's the address isn't?) is very very close. So on the other end it's this.

My understanding is that Kaminsky and Cohen weren't proven to be two different people, but Martin Fido, who was the one who discovered them and theorized that they were the same person, later decided that there wasn't enough evidence for that to even be a good theory, and withdrew the theory. Since then no one seems to have pursued the idea that they were the same person.

Then why we have full name - Aaron Davis Cohen? Fido suggested that David Cohen was a bit like John Smith in English but i don't think it would fit to Aaron Davis Cohen. I think that story of Cohen is a bit more refined. I think this can be useful: https://www.youtube.com/watch?v=0uIdC-ENk54
