Any other major finding or anything new?

also, did it compare the 1896 winters coming letter? this letter is the last document in the WC file and ive always thought that it might have been from the same writer as Dear boss/saucy jack as did the police at the time.
My reading is that they limited it to those received prior to the first letters becoming widespread, to reduce the possibility of copy-cat.

the present analysis will pay special attention to those early texts that were received not later than the 1 October 1888, before the content of the ‘Dear Boss’ and ‘Saucy Jacky’ was popularized by the police and the media and therefore hoaxers could have knowledge of it.

I read this last night.

Agree with GUT, they paid special attention to the "pre publication letters" i.e. all letters purported to have been sent by the killer PRIOR to Dear Boss and Saucy being published by the Press that are on file and recorded in 'Letters From Hell', Evans & Skinner.

This group comprised of 4 letters - including Dear Boss and Saucy Jack and apparently excluding the (probable modern fake) "17 September letter".

The second group is the "post publication" letters compromising all other letters on file. This included the 1896 letter.

All the letters are grouped in Fig.3 of the paper.

The conclusion was that the Moab and Midian letter was most probably written by the same person who wrote Dear Boss and Saucy - see Table 2 in the paper for an interesting visual analysis.

BTW in case anyone is wondering - the "threat letter to an unknown witness" postmarked 8/10/88 is the first label in pink titled JR 081088 directly below "Dear Boss" i.e the green group that also contains "Moab & Midian" in Fg. 3 of the paper.

If anyone wants to see how their "favourite" letter rated have a look at Fig 3. and DL the supplementary data file within the paper which identifies the letter and the label name used.

I've read the Introduction and skimmed some of the rest, and it seems to be very scholarly indeed. I will try to read it over the weekend,, as I have been interested in the so-called Ripper Letters and the public fascination with the case for some time now. Thank you for the link to the article.

The radial dendrogram lists nothing beyond 1891.

Rather pertinent as "Jack" died 9 June 1891.

Thanks Phantom

what does that mean though? its similar according to there analysis to saucy Jack?

if so, how is it similar-just the same words and phrases used? any handwriting comparison done in this study?

Hi Abby

The author doesn't specifically say anything about the 1896 letter apart from grouping it in the green label "Dear Boss" cluster in Fig.3.

The letters in this cluster e.g. Moab and Midian, 1896 letter etc. are considered the most linguistically similar to Dear Boss and Saucy Jack.

I presume that as the dendrogram radiates outwards from the green label "Dear Boss" cluster, they are considered more to less linguistically similar.

For example the pink/magenta groups directly above and below the green "Dear Boss" cluster are considered to be the next most similar. As the dendogram radiates outwards from these, the other clusters are considered less similar.

No handwriting analysis was done as part of this study. Linguistic comparison only.

The author also acknowledged the problem with plagiarism i.e. a lot of the "Post publication" letters are deilberately written to imitate the language of Dear Boss and Saucy, but he tried to factor that into account with the method he used.
