the doctors who did the autopsies and sighned the death certificates dident sugest there had been a murder and they would of had the advantage of actually examining the body
That's because they are only looking for natural causes.
From Thirlwall inquiry: evidence of one of the pathologists -
My question: why is it necessary to conduct paediatric postmortem examinations in combination with a forensic pathologist?
A. Well, if there is a suspicion that criminal activity may have led to the death or in some types of traumatic death where we might need the assistance of someone with forensic expertise then we perform the postmortem jointly and the role of the forensic pathologist is to consider matters of forensic importance and particularly those relating to injuries,and the role of the paediatric pathologist is to consider natural causes of death and look at growth and development and other medical conditions.
Q. So when you say the forensic pathologist looking for injuries, do you mean potentially deliberate infliction of injuries?
A. Yes.
Q. Because there is a suspicion --
A. Yes.
Q. -- that they may have been caused? Does that really from the off dictate who and how the pathology investigation should be being undertaken; if there is a suspicion, they go down a different route?
A. Yes. If, when a death is reported to the Coroner, it's clear that there -- it is a suspicious death from the outset, then the police will be involved and a forensic pathologist will be instructed as well as a paediatric pathologist.

Q. If he asked you the question: is there any evidence of deliberate external administration of air, how would you have answered that? What would you have said to that?
A. Well, that --
Q. Is that within your expertise or not?
A. That would have alerted us the fact that this was a concern of a criminal case and that this needed a much more in-depth and forensic pathology opinion. So if he had said that to us, we wouldn't have made a brief email response; it would have been apparent that that needed a very different approach.
