I had a Ripper doc on the other day. The conclusion was that it was a morgue worker, whose name I didn’t catch.
The kidney that was sent had indications of practiced knife skills, as well as a disease one of the victims had.
The kidney had been stored in wine spirits, available at the morgue.
The morgue at the time was at the geocenter of the killings.
The worker grew up in the area, mother being a hooker.
They attribute two other victims a predecessor, but more importantly, a final victim that had comparatively shallow cuts, which they attributed to the pleurisy of the morgue worker, which was his COD.
YMMV.
that would be Robert Mann —
