I still feel NC was murdered shortly after coming home. We don't know exactly when she got home, just after midnight per BC affidavit.
The strongest most compelling to me is the red fluid, but also the other things I have noted.
The red fluid is most likely wine. If it were blood it would have been noted by the ME. Below is a link referring UP to 2 hours to complete absorption. Possible wine still in the stomach puts this within 2 hours if not sooner after her last cup of wine.
Onion takes longer to exit the stomach. Link below. Meat was obviously not noted per autopsy, so this would answer why a possible piece of onion remained. Stomach contents usual are emptied within 6 hrs. She eats ribs at sometime between 6-8pm, stomach empty between 12- 2am. This 6 hour rule has been a rule of thumb for the last 30 yrs I worked in surgery. Anyone who has ever had a procedure is told nothing to eat or drink after midnight.
Brownish green vegetable material IMO is vomit. Again, the link states vegetable take longer to exit. DD is big on vegetable dishes as she has posted. I feel it would have been stated vegetation. Unless vomit is immediate once it has been in the stomach with other contents and stomach acid it will be brownish green. At least that is all the vomit I have unfortuntely witnessed.
Possible wine still in stomach, within 2 hours of last glass or sooner. Possible vomit of vegetables, within 6 hours of last bite. IMO she was murdered between 1-3am.
When large amounts of alcohol are consumed over a short time interval, or when a large quantity of food is eaten with the alcohol, the absorption phase may not be complete for up to two (2) hours after last consumption.

Some foods such as celery, onion, potato, corn and tomato skins typically take longer than meat or other foods to exit the stomach. This can be found on page 15 of 118. Warning! If you scroll futher there are gruesome photo's you might not want to see if you have a weak stomach.

Normally patients are fasted for 2 hours after clear fluids and 6 hours following a meal before they are anesthetised. This is to reduce the chance of any residual food remaining within the stomach.
