The "actual scientific literature" reveals that scientists do not much trust stomach contents as an accurate TOD indicator. Viz.:
Trigood, if you had been paying attention you would have seen my response to Sherlock_Holmes trying to use exactly the same paper to discredit this point.
Allow me to repeat myself, only substituting "Trigood" for "Sherlock":
Be honest here Trigood... have you actually read the article?
I'm thinking you didn't, because paragraphs seven to twelve of the discussion section concern themselves with "unusually well-defined circumstances" under which stomach contents can eliminate some possible times of death, and cites a case of a woman whose claimed TOD for her children was falsified because their stomachs were full of (undigested) food when she claimed they died eight hours after their last meal.
Since we are talking about unusually well-defined circumstances, where someone's stomach was full of (mostly digested) food, and this is being used to falsify the claim of a much later time of death, your article includes a caveat specifically addressing cases like this one. So if you had read the article then you would be guilty of deliberately misrepresenting its contents, but I'm going to be charitable and assume that you never bothered to look beyond the abstract.
Be honest here Trigood... have you actually followed up the citations for Table One ("Some agents and conditions of potential forensic importance and gastric emptying")?
I checked the most relevant ones and they turned out to be rat studies, unreplicated studies with eight subjects done in 1970 which contradict other studies done on the same topic and which involve the subject slamming five whiskies and so on.
The fundamental problem here is a lack of scientific literacy. You can't just find an abstract that seems to say what you want it to say and declare victory (although if you lack scientific literacy, it might seem to you that this is what other people are doing). You need to find out what the collected, relevant literature actually says.
I'm not sure what you're referring to when you mention Dr. Ronchi. As it says in the Massei Report PMF Translation, p 178, Dr. Umani Ronchi contradicts your main thesis:
Once again the question of scientific literacy comes into play here. If you actually read the text you quoted, Ronchi is making statements about how long the stomach takes to completely empty itself. Massei is discussing them because, well, the man's a fool. Since Meredith's stomach was full and her duodenum was empty when she died, the length of time it takes for the human stomach to empty has got nothing to do with the matter at all.
What matters is t(lag), the time for the stomach to start emptying. As we've demonstrated time and time again, t(lag) is typically around 80 minutes, and anything over two hours is already well into the range of the unusual.
The report goes on to state two other issues, on this page and the next, that support the later TOD:
1) The duodenum appearing empty could have been an artefact of poor handling in autopsy. Material in duodenum could have slipped into the small intestine. Therefore, part of her meal may have been in duodenum at death.
Yeah, except for two things. One, Dr Lalli would have to have been a total incompetent for this to happen because any remotely competent investigator ties off the stomach and duodenum before they start mucking around with the contents, to prevent exactly this happenieng.
Two, the autopsy video shows him tying them off. Which kills Professor Ronchi's fairy story stone dead.
But it's nice for us that he tried, because by doing so he confirmed for the benefit of those people who have the relative evidentiary value of the peer-reviewed scientific literature and the Massei report completely backwards that barring some such manoeuvre with Meredith's duodenum contents, she could not possibly have died at 23:30.
2) Presence of vegetal fragment in her esophagus plus a low alcohol level in blood could indicate MK ate another small meal at home, including a mushroom (say) and beer or wine. Alcohol slows down digestion, as well as the other food she ate.
You want to cite us a paper showing that a glass of wine, taken two and a half hours after the ingestion of a meal, will delay t(lag) for another three hours?
Because that seems wildly inconsistent with the literature I've read.
There is an "actual scientific" concept called the normal, or Gaussian, distribution. Most natural phenomena follow it. By this distribution, although most digestion times would mainly fall within the 2-sigma limit, there would be others that would fall under the long tail. This is one reason you cannot say that digestion time is absolute.
Yes, but a 21:05 time of death is already in the long tail, given she ate at 6:30 or earlier and we can establish this with confidence based on the length of the movie they watched.
Another variable is how much MK ate. It's possible she ate heavily as she was hungry from staying up all night the night before. Again, her friends were probably not taking notes on this at the time, unaware that she would be murdered later that evening.
You want to cite us a paper showing that a heavy meal of pizza, mostly digested at 150 minutes after ingestion, will hang around for another 150 minutes without beginning to progress into the duodenum? Because that sounds pretty far out there to me as well.
