Hi, "LooneyJohn"!
I read that nonsense at PMF.org, and was thinking of replying here, though I was in two minds about whether to dignify such drivel by addressing it. I found this comment by Stilicho particularly offensive.
I know they read over here, though, and I hope many of them will understand why (in more detail than anyone thus far has bothered to explain to them) their pet theory is flawed. This is why they lurk here in droves. If they weren't able to read your statement then they'd never know why or how they were wrong.
As I said before, the medical evidence for time of death is hardly my "pet theory", it's merely what I picked up on as being so blindingly obvious that I realised right then and there that unless the prosecution could come up with a theory of how Knox and Sollecito had killed Meredith around 9.20, they had to be innocent.
These publications the PMF crowd like to post are in fact cautionary tales to dissuade the inexperienced from relying too heavily on GI tract findings to the exclusion of all else. As the documents correctly state, there are a number of factors that can influence these findings, which must be taken into consideration.
Anecdote in spoiler tags - the squeamish are counselled not to click.
That's just an example of how other circumstances must be taken into account when interpreting the findings. However, the circumstances have to be
present. There's no point in saying, but maybe this or maybe that, if there's no evidence for this or that having been a factor.
The findings in the Kercher necropsy were that
the entire last meal was present in the stomach. 500ml - does "cardiol" realise how much that actually is? (I have some doubts whether "cardiol" is really medically qualified, but I think it may simply be that this person is not a pathologist and doesn't think about these things in a professional capacity. And people do sometimes use the word "pylorus" as shorthand for "pyloric sphincter".) And of course the duodenum was empty, and as I understand it, most of the jejunum right down to the ileum where there was some ingesta present. Not only that, but the constituents of the last meal were still recognisable in the stomach to some extent, in a semi-digested state.
It is
absolutely impossible for these findings to be consistent with a normal healthy young woman having eaten a meal with nothing "bad" about it (food toxins will certainly cause a meal to be retained in the stomach, but the others who are the meal showed no signs of food poisoning), and having lived subsequently for more than five hours, undisturbed for most of that time.
"Cardiol" thinks maybe stress caused intestinal transit to speed up, moving ingesta on from the duodenum to the distal jejunum. Wrong, for at least two reasons. One is that the
entire meal was still in the stomach, only semi-digested, so it hadn't gone anywhere. And secondly, if stress had caused such speeding up of intestinal transit, what about the large intestine? I'm sorry, but as LondonJohn says, there would have been stained underwear or other evidence of involuntary defaecation.
He also suggests vomiting as another possible confounder. I think even Stilicho corrected him on that. That theory would perhaps explain an empty stomach - but Meredith's stomach wasn't empty, the meal was still there. Also, "cardiol" has to postulate a selective and perfect clean-up of the vomit, which is clearly impossible.
This illustrates one of the double standards which are so prevalent on that forum. Anyone coming and making a point suggestive of innocence is immediately met with a demand for citations to show that their point has been unequivocally proven. "Please post a link to show that x was shown to be the case. Thanks in advance." But this nonsensical speculation about cleaned-up vomit (of food that was still quite plainly tucked up in Meredith's stomach) is allowed to pass without comment.
In contrast, a little way up this thread someone posted some speculations he clearly stated were speculation, as regards how Rudy might have got in and whether a staged burglary must inevitably have been staged by Knox and Sollecito. Stint7 (who is of course a completely separate person from Pilot Padron, even though both share some very unusual quirks of written English) immediately trots over there and posts a paraphrase of these musings, stating that they have been claimed here as being actual truth.
The sooner they just let these poor innocents out of jail, the better, in my view.
