Did he have anatomical knowledge?

[Trevor Marriott]

Thats a new one on me.
You must be referring to Chapman?, her legs were drawn up in the same fashion.

It was always my belief that if you stand close behind your victim strangling them until they loose consciousness, then lower their torso to the ground, laying their back flat out then the feet of the victim pretty well stay in place. Which means they bend from the knees, which is what we see with Chapman.

That was always my assumption.

and not forgetting that with the knees bent up would be hard to effect the removal of organs from the abdomen !

Exsanguination by leg bending

It seems to me JtR knew that by cutting their throats while on the ground, all he had to do was bend their legs upwards to increase the flow of blood out the neck quicker (also by the hearts own pumping action) and therefore have less blood to deal with in his mutilation.

There is no blood when eviscerating anyway until a major vessel is cut, which in the abdomen of a mammal lies next to the spine.

When are you going to stop comparing the anatomy of animals to humans!

Now the thing is anyone here might say, oh but anyone in a slaughterhouse can do that. However has anyone pointed this out before? I don't think someone who works in a slaughterhouse would be able to think that one out. It seems to me more medical thinking.

A good piano player doesn't have to look at the keys to hit the right ones.

No, but he's not likely to lose a finger if he makes a mistake either.

Does anyone know the make of amputation knife Rumbelow has?

Hi Jon,

Who knows why the killer did a lot of things? I understand your point about Bond's description of Mary Kelly's rib cage, although considering where the heart is located, the sternum and compactness of the ribs connected to it would still be - to me - an impediment without splitting the breastbone.

All I know is that a large mammal's heart can be removed by circumventing the diaphragm with the knife, firmly grabbing the heart from below with the off hand and cutting the attached vessels with the other while crouched to one side.

In field dressing animals, the windpipe and esophagus are also removed the same way. You just know to cut above where the other hand is placed. Then you simply pull down and out with the off hand.

Maybe everyone wouldn't be capable of doing this, but certain people would. A good piano player doesn't have to look at the keys to hit the right ones.

Something you might all be interested in with respect to the stocking cut.

[Wickerman]

"The intercostals between the 4th, 5th & 6th ribs were cut through & the contents of the thorax visible through the openings."

It is a shame Dr. Bond did not clarify whether he meant the ribs on both sides, or just one side. The intercostals is the space between the ribs, apparently muscles & tissue between those ribs was removed (but not between the other ribs?)
If it was not to enable the killer to see into the thorax, then what was the purpose?

Creating holes between the ribs would enable him to see where to sever the heart as he pulls it down towards the bottom of the thorax.

[Hunter]

Yes...

Hi Jon,



Hunters do it that way all the time. Helps keep debris out of the upper body cavity while dragging the animal out. Done by feel. Piece of cake.

Thankyou Cris.
This scenario though requires our killer to stand by the left side of the bed, reach up/under with one hand and slice the uppermost attachments with the other, while both hands are inside a human ribcage?

A piece of cake?

[Hunter]

Hi Jon,

...The killers (left?) hand will have grasped the heart from below, yes, but there is no way he could have used the knife (in his right hand?) to sever the arteries & attachments from below at the same time...

It's like the ripper had the key to be confident enough to make those severe mutilations

I see what you did there. ;-)
