Similarities between JTR and Thames Torso murders?

[RockySullivan]

Finding bodies has never been rocket science. Making a connection between two apparently unrelated murders is.

"These women were butchered and cut slightly differently days apart, therefore I see no reason they could be connected!"

[John Wheat]

And one strikingly dissimilar aspect is private acts vs public ones. The main objection I would have with this is the incorrect assumption that we already know which victims fell to the fellow nicknamed Jack the Ripper. It may be multiple killers within just the Canonical Group. To stretch a presumed "series" already on shaky ground to the extreme by suggesting all the murders of stray prostitutes in London at the time were by the same man is too far a stretch.

I myself think the C5 with the possible exception of Liz Stride were the work of Jack the Ripper. However I agree your point about attributing the Torso Murders to Jack the Ripper as a real stretch. The Torso Murders all involve dismemberment and the C5 don't.
