Hi Abby. As with all-things JtR, there's always that one definitive clue or piece missing which might tip the scales definitely to a certain consensus. In the immediate, he doesn't seem to be a killer out for a sexual gain just based on the nonsexual contact with the victims and the amount of time spent with them (well, except for Mary Kelly).
That's what I was trying to get at Robert, in particular with the brief amount of time it appears he had with some victims. I think in the case of Kelly though we may see some evidence that her killer "vented" on her. And there is a high possibility that she and her killer knew each other, and by the time and the state of her dress, Id guess pretty well.
In that instance there may well be some romantic implications in the damage inflicted...and perhaps in the organ taken from that scene.
If Kelly's killer "vented" on her how would you describe what was done to Eddowes? I see the same hand only just more time with Kelly.
The facial slashes and the wounds on the legs and arms cd, and I think the evidence in the Kelly case suggests she struggled somewhat with her attacker. I see in the Eddowes case a high probability that what was done to her was intended to create an impression, not just the result of the impulsive actions of a mad-man with a sharp blade.
