Flaws in David1819's Sheila scenario.

[Rob_]

Do you agree that the guilters explanation of how Sheila's blood got into the silencer - back spatter, is watertight?

No sorry Adam I believe the silencer was never on the gun that night.

Ok thanks Adam, however I think you will find that dried clots of blood do not dilute in water.

Clots of blood is quite common in you know what.

You know what I think, which is someone got lucky with the flake of blood matching Sheila's blood group.

Who?

Answering my own question, Rob believes it is watertight.

However he believes Sheila shot herself twice in an area of high blood flow with a contact & 'within 3 inches' shot, minus the silencer.

He needs to explain why there was no back spatter blood on the rifle barrel. Together with providing his silencer fabrication scenario.

A head shot I would agree, a contact shot to the neck I am not so sure. Sheila would have immediately fallen back. The neck area is nothing compared to a head shot in terms of splatter.

Where is all the blood from the other victims? cannot just be Sheila's in the silencer? if it is then surely this proves it was planted?

Do you have any sources that certain wounds were fired with a silencer on the gun? I have seen nothing conclusive?

I have already posted the distances & locations of the other shots. You should know anyway.

I do and there should be blood from some of the other victims present in the silencer.

If it wasn't Sheila's blood whose was it?  On the assumption it was Sheila's blood what viable options for a source exist other than 'drawback' as the jury was told at trial?

it's a blood group

it can't be ascertained

What can't be ascertained?

[killingeve]

Nothing to do with back spatter Jane, I thought two sets of groupings were required to get a reliable result? Just what I have read I don't set the standards.

To my knowledge only one was done I assume because of the small size of the flake of blood, but then you read there was a lot of blood in the silencer?

You need to read Dr Lincoln's report for the defence.

Again you keep saying diluted Adam? please explain.

The method used to determine the blood groups in 1985/6 was serological analysis using gel electrophoresis.  This requires good quality dried blood stains of a certain quantity.  Blood from a pair of menstrual stained knickers soaking in a bucket of water is a complete non-starter.  Many blood stained items were unable to yield results eg the rifle that had numerous blood stains on because the stains were too small or too degraded.

So you know why.
