I know you have been discussing Adam's favourite topics (Sea Wall and AM) but this is an important point. If the adult 's bodies were moved why does liver mortis suggest they were not moved.
Liver mortis begins within 20 to 30 minutes post death. However dependent on the ambient factors in play it can take between 6 and 12 hours to fully form. This is a very large time window. If a body is moved the liver mortis will change to the new positioning. Thus since we are talking of a 4 and a half hour time frame (03.00am to 07.30 am) more if you use the SOCO activity it is possible that the bodies were re-staged and given that PV only saw the CS photos his conclusions could be entirely accurate even though it is possible that the adult bodies were moved.
So it cannot be argued that the bodies could not have been restaged because of liver mortis.
