Rolfe, early on in this discussion, someone posted a link to a statement that stomach contents were "too imprecise to be useful" in determining ToD in the context of quite another murder case. Among the PMF fraternity, this morphed into "too unreliable to be useful", and they have taken this as allowing them to claim that "nothing can be concluded from stomach contents".
Of course, it is quite common for stomach contents not to be especially helpful in determining the time of death. That's probably the norm. However, in this case, the particular circumstances of the timing of the meal and the time when the victim was last seen alive make the stomach/duodenal contents absolutely crucial and compelling evidence.
And unlike a lot of the forensic work in this case, the evidence is that the
post mortem was meticulously carried out and the results are reliable. Despite various people dishonestly trying to suggest that "maybe" it wasn't done as carefully as all the evidence indicates it was.
AFAIK, this (along with one source which stated that maximum T(lag) is 4 hours rather than 3, and the fact that the median ToD based on T(lag) is a time when Meredith was known to be alive) is the only basis for the claim that the conclusion is in doubt.
You couldn't make it up.
I think you have to be peculiarly dense (or peculiarly blind and stubborn) to affect to doubt the time of death on these grounds. The four-hour time is the outlier - three hours is pretty much accepted fact. So Meredith was already close to the time when
inevitably food would have started to move on when she was killed. It provides an unusually precise time frame.
The idea that maybe we could stretch this to four hours still doesn't help if you're defending a scenario with a ToD at 11.40pm. And to say, well most people would already have started to pass food on by the time Meredith was last known to be alive, so in that case I can justify asserting that this still wouldn't have happened for another two or three hours, is preposterous.
Now we're all going to be accused of googling and having library cards.
Excuse me, I have to go, I have a
post mortem examination to perform now.
Rolfe.
