      Doesn't mention that the victims were first choked into unconsciousness. They were not subdued by the knife. No, I'm wrong, it does in one place.
      Also the Victorians kept very good records. I wouldn't call this a good source exactly, nothing new.

        Thank you so much C4 for enlightening us all on this subject. Now everybody finally knows that the couse of death for all victims (I presume since you write "the victims") was strangulation.*irony*

          Cause of death

          Hello Pierre

          Sorry if I was a bit harsh. What I said was that they were choked into unconsciousness. Of course the cause of death was blood loss following severance of the carotid artery.

          Your source seems to rely quite heavily on JTR books for information - something I thought you disapproved of, as they do contain inaccuracies. There is no evidence that all the women were prostituting themselves when killed. The keeper of the lodging house where Kate lived, for example, stated that she was never known to sell herself and Liz Stride had no need to that night, she had both money and something to sell if need be. The strangulation while they were lifting their skirts is not fact, but someone's theory. Whoever wrote this eould have done better to go directly to the sources for information.

          We have come to expect better of you Pierre.

          Best wishes

            PS We know that the murders were unusual - that is why people are still trying to solve them

                It's possible that the victims were strangled, however, there is no conclusive evidence either way. The Keppel study is usesful, but should be considered critically. For instance, picquerism is cited as a main signature characteristic, even though it's at least questionable as to whether such a condition actually exists. And, as has been pointed out, picquerism is usually associated with sadism, but I don't see JtR as a sadist. Reliance on the HITS database, I.e. in determining the rarity of the crimes/signature characteristics, has already been discussed: I've no doubt that these crimes are very rare, nonetheless we obviously can't assume that data from 1880s London would equate with modern data from Washington State.

                  Hello John

                  Beg to differ. Tabram's face was said to be so swollen it was almost unrecognisable, Chapman's tongue was protruding, Kate's hands were clenched, all signs of strangulation. Even Stride's hand was so clenched that they had to prise the cachous from her hand. I do agree with you about the piquerism though.

                    Research shows that his modus operandi is very unusual. For example Keppel et al (2005) has shown that the murders of this serial killer were linked by distinct personal signature characteristics.

                    They compared his murders to a 1981-1995 cohort of 3359 homicide cases in the US. The signature characteristics displayed in the murders of Jack the Ripper was found to be extremely rare.

                    There were only 6-8 cases where they found partly similar signatures in the whole cohort of 3359 cases.

                    So what do you think about this? And do you think it can effect the search for him and the research about him? How and why?

                    Pierre
                    I agree with this.

                      I think this means the case for WH Bury as the Ripper is an extremely strong one.

                          I disagree Steve if Jack is a rare serial killer than a killer who killed his ex-prostitute wife in a similar manner to the C5 must be seen as the leading candidate when compared to the rest.

                            Bury garotted his wife with a rope and hid her in a box, whereas Jack the Ripper slashed his victims' throats and left them in the open to be found. Even at this basic level, the MO and singatures are rather different, to say nothing of JTR's habit of inflicting extensive abdominal wounds and removing organs.

                              Its very unusual to group murders under 1 killer that are by evidence and definition incompatible too, so who knows what to think about this area of study at all?

                              There are 4 murders within a 5 person assumed group that have some similarities, and within that smaller group there are 3 that closely resemble each other in both Victimology and Methodology. Perhaps if people would follow a simple rule that dictates that things that are alike can be grouped we would have a much different perspective on these cases.

                              The desire to bundle murders despite their differences is a modern construct, due to the fact that modern serial killers can change their spots to elude detection or to explore new sensations. There is no indication to me that the killer of Polly and Annie sought to deviate from a preferred method and strategy.

                                But surely you can recognise the difference in murdering random prostitutes on the street, to murdering one's own spouse in the home?

                                Was Bury the Ripper? Dunno. But he's the only suspect who's a proven killer with a "Ripper-esque" signature, who lived in the East End during the murders. That puts him in a league of his own.
