Not especially Lookout. However, you said earlier you didn't think they were Sheila's feet either. If they are, then it's provable.
Because circulation has ceased,there are evident changes in the extremities,including the feet. In fact it's soon after death that these changes occur,and to be perfectly honest,what I've personally seen in someone deceased looked far different to the pics of Sheila in every way,which tells me that she hadn't been dead many hours at all. Even in the feet pics,there's no sign of spotting or discolouration,something which would have occurred if she'd been dead for the supposed length of time.
