I'm sorry - you're just plain wrong. None of the medical experts can come close to correlating the prosecution's time of death with the stomach/intestinal contents. The prosecution essentially claims that Meredith was STABBED at around 11.30pm - the time of the "piercing scream". This would put her actual time of death (at the brain stem) at a good 20-25 minutes later, given the nature of the wounds and the cause of death.
So, the time of the stabbing (if the prosecution is to be believed) was around 5 hours after the start of Meredith's pizza meal. Yet there was no matter in Meredith's duodenum. I guarantee that you will not find a competent forensic pathologist or gastro-intestinal specialist who would agree that a meal of this type and size would still be 100% within the stomach (and indeed not yet fully broken down into chyme) more than three hours after consumption. It's true that it can take up to 4-5 hours for the stomach to empty completely after a meal such as this - and if there had been matter in Meredith's duodenum then this indeed would have blurred the time of death significantly. But Meredith's duodenum was empty.
So, three hours after 6.30pm takes us to 9.30pm - and this is the outer time limit of established medical knowledge on when the stomach starts to pass a digested meal through to the duodenum in a healthy young adult who consumes a moderate-sized meal, followed by a normal, calm, relatively sedentary period.
Therefore....in order for the prosecution's case to stand up to the stomach/intestines evidence, two things have to essentially be true:
1) Meredith was confronted by around 9.30pm, but was not fatally stabbed until 11.30pm (the time of the "scream");
2) Meredith was in such extreme terror between the 9.30pm confrontation and the 11.30pm stabbing that her gastro-intestinal function ground to a complete halt during that entire time period (not merely slowed down, but essentially completely stopped).
Unfortunately, neither of these two conditions makes sense at all, and I sincerely hope that the defence bring in a couple of internationally-renowned medical experts to spell all this out in front of the appeal judges. As the defence already point out in Sollecito's appeal documents, even taking the most extreme range of the times presented in court in the first trial, the 11.30pm "scream" is totally invalidated.
I think there is scope to be very confident indeed that 10.00pm is the very outside estimate for time of death, and in fact I still think that this is being generous on timings - I think there are very many eminent people in this field who would be more than willing to stake their professional reputations on putting 9.30pm as the upper limit for ToD. Bit whether it's 9.30pm or 10.00pm, this ToD clarification will drive a coach and horses through the prosecution's (and the first court's) entire theory of the murder.
