David has not supplied a source to back up reply 9.

This is not surprising as there will be nothing saying whether testers could tell the difference between period and normal blood in 1985. 

What is agreed by everyone is that the testers could determine between human and animal blood and match blood to people. David is even saying they did this with watered down blood, correctly matching it to Sheila. 

It is inconcievable that the testers would not instantly be able to tell the difference between period & non period blood. Or that the relatives would not have checked beforehand whether the blood in the bucket was suitable.

This is not game over for David.

He does not agree with the industrial frame. Believing the relatives acted alone. Quite where the 60+ pieces of forensic evidence from the COA came from, must just be human error.

He just has to say the relatives put someone's else's blood inside the silencer. Which was a close match to Sheila's.

Read the evidence and trial transcripts. They only tested the blood for blood groups. It never crossed the lab staffs mind to do anything else.

The relatives would have checked to see if period blood could be used. In such an intricate & serious frame, they would not make such a glaring error.

The lab would have tested to see if it was human blood and normal blood (not menstrual). Once confirmed, they would have started the grouping.

It may not have been neccessary to test to see if it was human & normal blood. These things may have been obvious without tests.

If they were able to determine watered down blood put in a silencer matched Sheila's, they would be able to determine what type of blood it was.

They struggle to even do that now let alone 1985.

This was written in 2018

"Driven by the importance of forensic body fluid identification, novel methods have been extensively researched over the years including microscopic examination messengerRNA, microRNA (miRNA), and DNA methylation profiling, which have been successfully applied to the identification of blood. However, distinguishing peripheral blood from menstrual fluid with these methods has been shown to be highly challenging, and the application of more complex molecular techniques requires a considerable amount of training and experience."

You need to provide links. As I did.

If the labs were able to look at a tiny amount of blood in a silencer, which (in your view) had been diluted in a bucket of water, then correctly determine it was Sheila's, they would have been able to determine whether it was normal or menstrual blood.

They only tested blood for grouping, nothing else. Only extensive testing would show whether it was menstrual or not by the waste products contained in it.

ABO testing only yields the blood group. The lab dissolved the blood in distilled water in order to carry out the test.

This is the procedure they used. the Absorption-Elution Technique

'Sheila’s menstrual blood (which was watered down inside a bucket) was planted deep inside the silencer, in EXACTLY the same pattern that back spatter makes is impossible. Menstrual blood is not like normal blood. It doesn’t coagulate, for one thing. It also contains tissue and mucous from the uterus, has different cells, and has fewer platelets, less haemoglobin and is completely different. The forensic team would have immediately seen just by looking at it that it was menstrual blood.'

NOPE !

It is not me saying it.

You do not have to automatically disagree as you believe Sheila's blood fell into the silencer mid massacre.

What blood of Sheila's would fall into the silencer mid massacre. She only bled after being shot.

The blood flake tested negative for PGM
